Gift To The Future

Gift To The Future

We, the people of the 20th Century and the beginning of the 21st are bequeathing our descendants a grim legacy: too many people, many resources running out (crucially and perhaps declining already: oil), and environmental damage (including a significant increase in atmospheric CO2 with unknown consequences that might be very serious).

We would like to fix these problems, but realistically many will get worse rather than better. The loss of resources has many people fearing a significant collapse of our civilization, perhaps in the form of a serious and ever worsening Depression. Rather than just aiming to solve all the problems, we need to also make a gift to the future which will help them cope with the problems that we don't completely solve.

For old folk like me, the Gift to the Future is for our grandchildren and for the preservation of our civilization. For younger readers there is an extra good reason to make a Gift to the Future: You'll be there.

The Plan

The detailed justification is provided in more technical sections below. The plan itself is very simple.

In the energy business, as in many important businesses, we can divide the costs of running a particular bit of that business into the initial up-front costs (mostly construction costs), and then on-going, marginal, costs. In a normal way money is borrowed to cover the initial cost, then revenue is used to cover the resulting interest payments and the ongoing costs. For the business to be profitable, and not go broke, the price has to be high enough to cover both. However the energy business can't typically set its own price, which is dictated by the market: by the amount of demand at each price point, and by the actions of other sellers. For the seller it is best to sell whenever the price at least covers the on-going costs.

It is very difficult for business to build energy infrastructure in the current and near future environment. Interest rates are uncertain, energy prices are uncertain and if the declining production of oil leads to economic decline then demand may be low. Yet failing to build energy infrastructure guarantees economic problems. 

We need to cut this disastrous loop by making the initial up-front cost of new energy infrastructure as a Gift to the Future.

For America this will be a radical proposal, but for most countries it is just a return to normal. Most countries have traditionally run their energy infrastructure as a socialist part of a mixed economy. Energy infrastructure has been built by the central (or regional) governments from tax revenue and national borrowing. The radical aspect of the proposal is to get well ahead of obvious demand growth, to be ready to cover for reduced energy from fossil fuels.

There are however tricky aspects of the plan that are considered in the following technical sections.

The Energy Market

In the natural world, species are never content to enjoy a comfortable existence. If things are comfortable then the population increases until things aren't comfortable any more. Capitalist energy is like that. The most marginal oil producer is walking a fine line and can't afford any increase in costs or decrease in price. Consider an electricity supplier that owns its plant outright and is making a nice profit on the electricity sold over the marginal costs. In those circumstances modern management feels compelled, by threats of takeover, to mortgage the production facility, pay the cash to the owners (and managers) and continue on the edge with revenue having to cover interest as well as on-going costs.

Having the energy industry on a knife edge is worrying. There is no spare capacity at the current price. It is hard to know whether a rise in demand will be met in time by increased production. Indeed it is hard to know whether any significant increase in production is possible for some energy types. Occasionally we get a clue. The 2008 price spike in oil failed to bring significant extra sources on stream. It is very easy for electricity production to not be ready for rising demand, as we've seen in Pakistan, South Africa and many other places down the years.

Government intervention in Energy

Outside of America, government intervention in energy has been common. In European-style mixed economies, electricity and natural gas supply have been seen as natural monopolies and core infrastructure, and so have been commonly run as government services. In recent years governments have sold off energy infrastructure and most places are now in a similar situation to America.

Once infrastructure is in private hands it makes government initiatives tricky. If the government becomes a participant in the market, this is going to damage the private participants. Presumably compensation should be paid. This is particularly the case where the government has recently sold its previous infrastructure.

The straightforward way to proceed with the Gift to the Future is to (re)nationalize the electricity and natural gas industries. Then the addition of substantial non-carbon generating capacity can be done without consideration of the impact on other businesses. When the energy crisis is passed then governments may choose to privatize energy infrastructure again.

The Energy Crisis

The culture and prosperity of the modern world stems from the exploitation of fossil fuels, starting with coal in the Industrial Revolution. There is a limited quantity of these fossil fuels (coal, oil and gas) and naturally we have been using the best quality and most conveniently located first. So increasingly the fossil fuels we use are more expensive to acquire, and deploy. As the cost goes up we see a narrowing range of uses to which fossil energy can be cost-effectively deployed. And as a simple mathematical fact, as you use up a finite resource there must be particular months and years which represent the highest points of production. Whether you perceive this as peak demand or peak production doesn't matter. The world economy has expanded on increasing use of these fuels and must contract as use of these fuels contracts. That's the medium and long term crisis, but there is a more immediate problem.

Liquid fuel is the most convenient form and so oil has been the most important fossil fuel. The experts are unanimous that the days of easy cheap oil are past. Indeed 2005 was a recent peak of production of oil as it came out of the ground, though 2008 was slightly higher when you include liquid hydrocarbons obtained more indirectly. What we did see in 2007-2008 was that a massive run up in the price of oil was not able to induce significant extra production. Subsequent lower prices have seen the postponement of some exploration and development. It is not unlikely that the plateau from 2005-2008 will be the peak of oil production, and the practical impossibility of obtaining higher rates of flow represents a cap on world economic production for as long as so much infrastructure, particularly transport, is oil dependent.

Burning fossil fuels also creates a wide variety of serious pollution. One inevitable part of burning carbon-based fuel is the creation of CO2, and since it is a trace component in the atmosphere we have been able to make a significant change to the amount of CO2 in the air: from 280 to 380 ppm (parts per million). Most scientists think that it would be wise to stop increasing the level of CO2. Consequently significant sections of the populations of Western countries oppose the expansion of the coal power industry. This political fact is another part of the Energy Crisis.

The Electric Society

Non-carbon energy sources only produce electricity. You can do a lot with electricity. You can split out the hydrogen from water: and possibly use hydrogen as a portable fuel. Perhaps more sensibly one can make more manageable fuels like methanol. Or we can do a lot more things electrically: such as battery (plus capacitor) powered vehicles; railway electrification; heat pumps for heating and cooling.

Whether one generates fluid fuels or uses batteries, there is a substantial loss of energy compared to the magic of oil-derived fuel. So it is not going to be good enough to add electricity supply with equivalent energy to current fossil fuel energy. We need to add much more. We need to generate about triple the amount of electricity that we currently do.

It is crucial that we start this massive build up of carbon-free electric generating capacity as fast as we can. We don't have time to spend agonizing over whether the returns will cover the interest payment. If they do, that will be good. If they don't, that will be because the future is in even greater need of our gift.

Nuclear, wind and solar

Nuclear, wind and solar meet the criteria for the Gift to the Future. The majority of the expense is up-front. Once they are built they provide cheap power. Wind and solar have additional deployment costs associated with energy storage (since they are not always available) and an improved electric grid to cope with the level of variability.

The decision of how to implement the Gift to the Future is an engineering decision. Nuclear has to be in the implementation options for the Gift to the Future, because without that option it will be seen by a significant proportion of the population as yet another Green fantasy.

Notes

When individuals save for future problems they might save money. Society as a whole can't do that. Taking money out of the economy would cause deflation and force the central bank to create more money. Similarly if a substantial amount of money were brought back into circulation it would only cause inflation, it wouldn't deliver wealth to the future. Sometimes one country can try to save money in the currency of another, as China has by investing in America, but we can see that that has put them in a difficult position having lost control of the value of their savings.

We also note that the Gift to the Future would discourage private companies and individuals from investing in energy research. This is something that needs to be addressed, guaranteeing inventors that successful research and development will be well rewarded.

Summary

The Gift to the Future cuts through a lot of the argument about predicting the future. It is an insurance policy. You don't have to believe the climate computer models to worry about the significant change in atmospheric CO2 and other gases. You don't have to subscribe to the theory that Peak Oil is here now to believe that we need to prepare for an electricity-based future with energy security.

The worst that can happen is that we are unnecessarily poor now, as we construct more electric power generation than is immediately needed. The decision to be poorer now to save for the future is one that we all make at times in our lives. Society as a whole can't do that through saving money. We need to actually invest in core infrastructure. Energy is the most important infrastructure for our modern society. The Gift to the Future is a gift to ourselves. This is something everyone can understand.

Carbon politics after the ETS

Carbon politics after the ETS

In all interesting team games the good players are thinking more than one move ahead, and the most interesting team game is politics. Consider the ETS. It is, in principle, a brick wall. We set a cap on our carbon emissions and emitters are forced to trade to stay below that. The assumption is that the magic of the free market will supply the best possible way of staying below the cap with minimal economic pain. 

Does the free market have enough common sense to avoid running full speed into a brick wall? This was amply disproved in 2008 when the economy proved totally unable to prepare for the spike in oil prices which has been predicted for decades. We don't need the magic of the market to work out how to get over the ETS brick wall, because there is only one possible way.

Things that aren't going to work include: the hydrogen economy, carbon capture and storage, solar energy of any sort, covering the landscape with wind farms, building dams, switching agriculture to producing biofuels, geothermal, tidal dams, stopping cows from farting. Many of these involve mankind making a grab for ever more of the limited resources supporting life on Earth. It is a relief that they won't do the job, so that we will be forced to move to the one energy source that nature isn't interested in.

The only thing that will get us over that ETS brick wall without economic disaster is Nuclear Power. Which brings us back to the game of politics. Once Malcolm and the Coalition get the ETS signed up, then they can roll out the Nuclear solution. It will be trivial to use the Senate's powers of enquiry to tear all the alternative options to shreds. They can unwrap a Nuclear policy, complete with a proof that nothing else will do the job. And then suddenly the boot is on the foot. Nuclear Power will tear the ALP and the Greens to shreds, since so many of them think that the truth should never be allowed to get in the way of a good fantasy.

Is anybody in Australian politics thinking more than one move ahead? It is hard to know. You would think that such a plan would make it easy for Malcolm to get Senators to pass the ETS. However he may be wary of discussing it, given that many in his party hate his liberal views, and others are just too talkative to keep quiet about it. I suspect however that is is the clued up ALP that can see this possibility. They'd prefer to have the ETS fail. This avoids the problem. Once again such a cynical intention could not be shared with the rank and file MPs, so we are not likely to ever know. Still it will be interesting to keep this next move in mind while we follow the struggle for an ETS.

World Saving

World Saving

During the boom, China saved for a rainy day. This now looks wise, but it was only possible because of western countries doing the opposite. We no longer hear Eastern leaders saying that "the West should save, as we do". I guess they've figured out that it is impossible for everyone to save money.

Money is funny stuff. You can't actually move wealth into the future through money. That seems silly, since we do it all the time. However what actually happens is that when you put your $100 in a jar under the bed, then you create a tiny bit of deflation that makes all other dollar holders richer. Then when you take it out and spend it ten years later you cause a tiny bit of inflation that makes all other dollar holders at that time poorer, and that wealth is transferred into your $100 as you spend it. If you doubt this think: is any real wealth lost if the money is accidentally destroyed?

A country can only move wealth into the future through money if it is some external currency. This however puts that country's savings in the hands of that external country, as China has found. And when the amount of money under the bed is in the trillions then the normally prosaic act of getting it out and putting it back in circulation becomes quite tricky. However that may turn out, the relevant point for this discussion is that:
The World as a whole cannot move wealth into the future through money.
And yet there are a number of reasons why the World as a whole should now be doing all it can to prepare for a rainy day. Even though things aren't too flash now, they will get worse on the peak oil down-slope, before we can get the inferior alternative energy sources operational. We need to save.

Saving means doing things now that don't translate into consumption now. This means less consumption now: the very reverse of trying to restart business as usual. 

The simplest thing to do is to stockpile useful stuff that is, or embodies, energy. That's what China is doing now: saving oil and iron ore instead of saving money. But there's another name for that: "hoarding". It is an amazing feat of modern thinking to perceive a simple act of preparing for the future as a negative thing. The explicit value of hoarding oil is that it is much more valuable than the current price: quite valuable enough to justify long term storage costs. The act of hoarding raises the current price. This might annoy current consumers (hence the negative name), but this is something we need to do to sustain the oil industry and postpone a complete collapse of the oil industry and everything else. Of course the cheapest place to store it is to leave it where it is, hence Sarkozy's suggestion of a producer-consumer deal on prices, but this seems likely to be politically impossible.

Another thing to do is to build infrastructure now that will be useful later. There's a lot of infrastructure building going on, but a lot is seriously misguided: like extra freeways. The infrastructure we need is for energy and for electrification of transport. We need to build those things now, even though they aren't justified by current economic conditions. Businesses don't spend money to prevent social collapse: that's the government's job.

Using public transport and occasional taxis is cheaper than owning a car. However, once you have (rightly or wrongly) bought a car, it changes your decision process on transport. You can now undertake trips that wouldn't have been justified previously, based on the marginal cost of using the car. You don't include an allowance for the sunk cost of the car when deciding whether to use it for a particular trip. This brings me to the next point.

Having built our low marginal cost energy plants, and our wonderful double track electrified railway network, then we need to make maximum use of those resources. We need to let the price we charge for them drift low towards the marginal cost (including maintenance), not try valiantly to make enough money to cover our sunk upfront costs. If it was possible to cover those costs as well as the marginal costs then business might have built that infrastructure rather than the government.

So how would we actually do this? The aim is to reduce the amount of consumption for immediate use in order to have money and workers available for the infrastructure costs (and for stockpiling as well). The way to do this would be to follow the model of "War Bonds" during war time, and issue "Energy Crisis Bonds" to soak up money. What such bonds should promise to preserve is their value as a fraction of total national wealth. Since the activities are not designed to be rigorously economically justified, they might reduce total national wealth, and hence the value of the bonds, but people will actually be happy to accept that if it is up front. And indeed we know that national wealth will decline in real terms for quite some time for other reasons. People are actually more interested in keeping their share of the total pie, rather than taking risks to preserve value in absolute terms.

There are other ways of saving:
  • Useful education (small farming?);
  • Relevant research and development (forget going to the moon);
  • Cleaning up environmental problems rather than leaving them to our poorer descendants;
  • Building a low power, mostly text, mostly wireless, free Internet infrastructure for relevant applications (such as education and transport optimization);
  • ...your ideas here...

If the government were to do as I suggest and build energy and transport and provide them cheaply it would undercut businesses trying to deliver these services. Apart from fairness concerns, there have to be serious doubts as to whether governments can make good decisions in these areas. But it seems clear that business perspective is too short term and won't move until too late. The traditional American answer is to provide carrots and sticks for business to move in the directions that government wants. This often seems to combine the worst of both worlds, with poor targetting (e.g. biofuels) and it is very difficult for government to walk the line between too little incentive to do the job and too much granting windfall profits. My feeling is that we need a bit of socialism for a while to have any chance of getting through the Peak Oil downslope to hopefully find the nuclear electricity plus natural gas upslope. Leaving the energy/financial crisis to private enterprise will eventually leave the world's important assets in the hands of a small number of men who are more noted for their ruthlessness than their public spirit.

Even if the details are wrong the fundamental point is right: One of the things we need to be doing is saving and the thing we need to be saving, in various ways, is energy.

Free Will

Free Will

Many systems behave with very exact determinism. The circling planets and a sphere rolling down an incline were examples that attracted applied mathematical treatment in the early days of modern science. When it became apparent that humans were systems built from the same stuff as inanimate objects it came to be thought that the behaviour of humans must be exactly determined. If you could know the exact state of the person then that persons responses could be exactly calculated. This was interpreted to mean that people don't have free will.

Then came the quantum revolution. Systems don't have exact state. The state of a system and its evolution are only determined statistically, not exactly. This was seized on by some as restoring free will.. This never made any sense to me.

Instead of mapping out a persons exact future, we can instead only map out the probability of all possible futures. Or if you prefer the multi-worlds interpretation then we can map out all the person's futures and how frequently each occurs. It is a mystery to me why anyone feels that this bestows any more free will than the more exact Newtonian determinism.

The problem of free will comes from the intersection of the ideas of science with the idea of an infinite God. God is envisaged as being able to do infinite amounts of calculation at infinite speeds. If we remove the idea of an infinite God then the problem of free will disappears.

Lets suppose that we wish to solve the problem at the heart of the free will issue. We wish to enter the state of a person into some computing device and extract information about the future behaviour of that person. If a person was as simple as a perfect sphere rolling down an incline then we would expect an easy and definitive result.

One possible way to address the problem is to make an exact copy of the person and follow the behaviour of that copy. Effectively we are using a human as a calculating device giving back information about human behaviour. A key question is: can we do better? Can we build a simpler system which will predict the behaviour of the person. Science now understands the butterfly effect: where in unstable systems small changes to small parts rapidly expand their effect to alter the macro state of the total system. Mathematically we now also understand that most information, such as the information describing the state of a person, is incompressible -- it can't be described by a simpler system.[1]

It thus seems overwhelmingly likely that you can't build a simpler system to determine the evolving state of a person. What this means is that the only effective way to find out what a person will do in a given situation is to put that person in the situation and see what they do. To rephrase that:

Observing what a person does is the only way to find out what that person will do.

To me this expresses the fact that the person has free will. The person's actions are not "determined" in any physically meaningful sense.

There is a problem with this interpretation. It also applies to hurricanes and bacterium. Clearly a hurricane doesn't have free will because it doesn't have will at all. A becterium, like a person, does act purposefully to decrease local entropy. If you don't want to allow that a bacterium has free will then the next step up is to creatures which have specialized cells used for decision processes. It seems unlikely that this is a hard break. Probably as soon as there is some cell differentiation then some cells are more concerned with decision and others less. And from there to people there is no clear cut point where we could reasonably divide those with free will from those without.

Sadly even the break between life and non-life is not that clear cut. Perhaps we are forced to the straight forward view that some things have more will than others. Will is always free will because the extent to which a systems actions are predictable by a simpler system is also the extent to which we would not identify something as really displaying will at all. We thus return happily to the sensible view that prevailed before the imaginary monster of determinism arrived on the scene.

[1] somebody, probably Chaitin, proved "nearly all information is incompressible" or something like that.

The Crisis

The Crisis

Overview

The current financial crisis is not understood correctly, and the proposed solutions are thus incorrect.

The crisis is caused by the inability of the modern economic system to deal with a declining economy. The declining economy is an expected consequence of the Energy Crisis. The fact that oil production is increasingly incapable of keeping up with the demands of a growing economy is the first phase of the Energy Crisis. Later phases will be even worse unless we prepare now.

The Crisis is not about confidence, it is about real underlying problems that need to be addressed. The desire of people to take steps to prepare for the future is correct. The desire of governments to restart business as usual is wrong. People prepare by saving money. This is not the correct way for society as a whole to respond.

This document will mention many actions by society that might contribute to a solution. There is not enough leeway for us to go down many wrong paths. We need to make decisions based on hard-headed numerical calculation and vigorous open debate. We need to minimize decisions based on sectional interests and hidden agendas.

We need to accept that there will be a period of greater central control of the economy, and greater public ownership of economic assets. A Republican administration in the US has found that it needs to acquire an insurance company, so this should be obvious. It needs to be done in a more organized way. We need to plan for Long Crisis Socialism, not just do one ad hoc nationalization after another.

The Crisis will be marked by oscillations between periods of decline and deflation, and periods of economic revival and inflation. We need a better way of dealing with deflation. Current proposals to combat deflation by printing money and spending it randomly will work out badly, particularly if politicians get their hands on the money without oversight.

We are going to be short of expertise for many things we need to do. We are going to have to proceed bravely using intelligence and knowledge, as we do in wartime. The Internet makes knowledge accessible, and is a key tool.

Preamble

We face multiple crises: an energy crisis, a financial crisis and an environmental crisis. Let's just call it The Crisis. We will emerge from The Crisis significantly poorer. But the majority of people in the developed world, the middle class, will be happier, because they will have reclaimed their lives from the incomprehensible and incompetent economic powers that have imposed the current massive economic inequality on society.

According to the statistics we have enjoyed 60 years of nearly uninterrupted economic growth. Surely the middle class has benefited enormously from that? Let's compare the median American 2 child family between 1972 and 2006. In inflation adjusted terms the 2006 family spends significantly less on food, on clothes, on appliances. However they spend 70% more on housing. Does this mean they live in a big new McMansion? No only richer folk do that. Our median couple live in a fractionally bigger house, 6.1 rooms instead of 5.8, but it is 20 years older. The 2006 couple is less likely to have health insurance. The other new cost is education for pre-school and then for college. The significant fall in wealth is despite the fact that in 2006 it is much more likely that both parents work, even with very young children. The two jobs necessitates 2 cars. The final straw is this: in 1972 our median couple was saving 11% of their income. In 2006 it is -1%. Our 2006 family is gradually sinking into debt at the rate of 1% of income per year.

America is, in fact, poorer in many ways than it was in 1972. The reason is that 1972 was the peak of US domestic oil production. Since then an increasing amount of oil has come in from the global oil market, with wealth pouring out in return. But wait, a lot of the outgoing money isn't spent, and returns to America in loans. A giant financial industry grows up, skimming off enormous wealth while selling the white powder of debt to the increasingly impoverished American middle class. It was in fact a giant Ponzi scheme, dependent on new borrowing to prevent a credit collapse. Then the world as a whole hit peak oil in the 2005-2008 period. The resultant oil price spike pricked the debt Ponzi-like scheme. The economic collapse continues as this is written (Dec 2008), with no end in sight.

Society needs to make massive changes in basic infrastructure. It is abundantly clear that the current capitalist financial system is going to fail to support this work. We don't have the resources to get this work done while preserving the extravagant frivolous lifestyle of the rich. And indeed we can see that the rich have not been making the constructive contribution to our society that has been claimed and which might justify their privileges. How the middle class responds politically will determine how we come out of this crisis in 20 years time. We can go through a period of socialism and planning to get the job done, then transition back to an improved free market system that is ponzi-proof and doesn't require the current excesses of social inequality. Or we can just let the crisis play out with endless unplanned government interventions supporting the rich, and finally emerge with the massive social inequality that prevailed before the Industrial Revolution. The middle class is big, and waking it up is not easy, but that is the only route to change we can believe in.

Socialism is a dirty word in much of the West, but even Republican America is doing ad hoc nationalizations now. What we need is serious well-planned socialism. I commend Mike Moore's plan to socialize the American car industry for the duration of the crisis, but it needs to be done in a much wider planning context.

We'll start by trying to understand The Crisis before getting back to solutions and how to get there.

Money

The first thing to understand is money. Money is certainly funny stuff, and our understanding of it is rather coloured by the way it used to be a redeemable stand-in for some physical stuff (typically gold). As it currently operates money does two things well, and is pressed into service for some other things which it does less well, particularly in volatile times.

The things money does well are:

  1. Act as a medium of exchange to avoid the inconvenience of barter;

  2. Provide a measurement of the relative value of things at a point in time.

Money is not so good at providing a comparison of value across time. This is not just because of inflation and deflation, but because the relative values of things change, so that inflation and deflation are not well defined: they only make sense if you know exactly what basket of goods and services you are considering, and typically the basket that makes sense at one time is incorrect for a different time.

Money is used by people and organizations to move wealth into the future. We put dollars into a suitcase under the bed, and spend it at a later time. It seems as if the money in the suitcase is a magical store of value, but that is very misleading. What actually happens is this: when you put the money in the suitcase you take it out of circulation. This reduces the amount of money chasing the same amount of goods. This causes a small amount of deflation, making everybody else holding dollars minutely richer. Then when you get the money out of the suitcase and put it back into circulation, that money acquires its value by causing inflation and taking a small amount of value from all the other circulating money.

It is important to see that this process, which makes it possible to move wealth into the future through money, only works for entities embedded in a relatively stable wider environment. Society as a whole can't move wealth into the future through money. We'll come back to this point later. Real wealth isn't money, it is useful physical stuff, and knowledge and expertise. Some of it can be moved into the future, but most loses some or all of its value in the process.

There is a real economy out there with real goods and services and activities. One needs to think clearly about that, and not think too much about money. That's what we'll be trying to do in this document.

The Energy Crisis

The prosperity of the modern world has been built on cheap fossil energy, starting with coal for the Industrial Revolution. This fossil fuel is running out much more rapidly than estimates from official geological sources. Oil, and particularly cheap good quality oil, is evidently running out first. Even when the price was recently very high it was not possible to expand supply. Demand is now down because of the worldwide economic meltdown, but we are still using up this finite resource at a great rate. By the time demand recovers, the maximum available oil production rate will not be able to reach the plateau that we've seen from 2005 to mid 2008. It is almost certain that the peak of oil production is behind us and a long and bumpy decline lies ahead. The core job of governments over the next 20 years is to manage that decline and optimize the changeover to other sources of energy. More on that later.

This document will assume that we've passed peak oil, with peak natural gas and coal to follow within a decade or two. If you don't agree with this then what follows will describe a future rather than a current problem. That would be great. There would be time to prepare and possibly avoid any monumental economic catastrophe. But make no mistake: there has to be an end to exponentially rising consumption of finite resources (in this case fossil fuels), and there will be something like a bell shaped curve, with a peak followed by decline.

Oil use tracks the economy

The last 60 years have been the age of Oil, and the clearest indicator of that is how closely the world's economic production has tracked up and down with oil production. It makes no sense to ask which causes which. We saw how quite small reductions in oil production during previous oil shocks lead to matching economic declines. Most of the time we've seen the reverse, with a rising world economy demanding more oil, and until recently getting it.

The world's economic infrastructure, particularly transport, is tuned to oil. The economy will decline with oil production, though at times it won't be clear which is leading and which is following. As we switch away from oil, the economy will eventually decouple. We need to make sure that happens sooner rather than later. Some Peak Oil commentators think that this won't happen until there is something like a complete collapse of civilization. I don't believe that, but I do think the problem is very serious, and how bad things eventually get will be determined by the quality of our response now. If there was a break in the continuous thread of industrial civilization, then, with all the easily accessible resources used up, our descendants would have a much tougher time rebuilding an industrial civilization than our ancestors had in building it. Quite possibly there will be no second chance.

The Tsunami Effect

Those likening the current economic problems to a tsunami are more correct than they realize. The characteristic of a tsunami is that a sudden change in the ocean floor requires the ocean to make a matching change. But it can't make the change across the whole ocean instantly. Instead it makes a much larger change locally, and that change is communicated to the rest of the ocean in a series of waves. Suppose there is a sudden uplift in a part of the ocean floor. Then instead of lifting the whole ocean a minute amount, instead it lifts the water just above the uplift by a lot. The top of that water is then higher than the surrounding ocean and collapses outwards as a spreading wave. It collapses so fast that it overshoots downwards creating a local trough at the scene of the uplift. This then follows the spreading wave with a following spreading trough. And so on, so that we get the series of peaks and troughs that characterize the tsunami.

Something similar happened during the recent rise in the oil price. The underlying dislocation was the sudden appearance of an unbridgeable gap between the demand for oil at the prevailing price and the available supply at that price, and indeed supply was unable to rise at any price. There was a need to reduce demand to match supply. But it was impossible to reduce demand in a uniform way across the whole economy, since so much activity was predetermined by existing contracts and unavoidable use. So the bits of the oil demand that were able to reduce needed to be hit extra hard. The price had to go up enough to stop vacation and other optional driving across the world, and other easily modified behaviour. To do this the oil price overshot upwards by a lot. At the prices that were reached, many companies were the living dead, continuing only on momentum and hope and existing contracts.

The effects of the high price spread out like a wave, touching enterprises that aren't obviously much affected by the oil price. At the time of writing (December 2008) the economy is in free-fall. It has already dropped enough so that there is no shortage of oil, but it has much further down to go before it rebounds. When it does recover it will once again rise enough to hit declining oil production, the oil price will again soar, and a new episode of economic collapse will start. These are the waves of the Peak Oil Tsunami.

The future promises to actually be messier than the picture above suggests. Jeremy Grantham, chairman at Grantham Mayo Van Otterloo, an institutional money manager, said recently: "The global economy gives a good impression of having run at top speed into a brick wall". It is doubtful if we will get up that head of steam again. So the next time we will run into peak oil at a slower speed, with some parts of the world economy going well, and others less well. The price break out will be less dramatic and the crash less catastrophic. Maybe we'll ride the wave down the slope for a while instead of wiping out.

The Financial Crisis

Many think that the economic meltdown is just a result of problems in the financial system. It is certainly hard to disentangle these issues, but we'll try.

Recycling Money

In a barter economy, if you wanted to save for the future then you'd acquire durable stuff that would be useful later or exchangeable later. In a money society we like to save money. But money is funny stuff. If someone saves money then someone else has to go in to debt, to balance it out. Maybe you think they could just put it in a suitcase under the bed, but that would cause deflation and the central bank would end up creating money to lend to balance it out, aiming, as they do, for 2-3 percent inflation.

Unfortunately the world is cursed with some very determined savers. This includes the Chinese government and, most relevantly to us, some of the major oil producers. Hasn't it been a cosy deal. They send us oil and we send them bits of paper: dollar bills, bonds, equities. Much of this paper is turning out to be worthless. A huge financial industry grew up to recycle oil money back into the Western economies as loans. Hundreds of millions of dollars, or more, was siphoned off as our enthusiastic savers were connected to ever more dubious borrowers. “You mean I can live in this house for nearly nothing for 2 years, then walk away when you put the interest rate up?”; “Yep”. Then the lenders borrowed more money using those mortgages as collateral. Wow.

Still, no real wealth is destroyed by this chicanery. A lot of wealth has ended up in the wrong hands. The fact that banks and other financial institutions (and even countries) are insolvent is a real problem, but can be fixed, as we are seeing.

The real problem is that we have a declining economy and our economic system is not designed to handle that correctly. The oil price overshoot was always going to lead to an economic (and oil price) crash. But the management of the crash is incorrect. In particular allowing deflation is disastrous.

Deflation

The prices of houses and other fixed assets are declining. The prices of commodities are falling. This is deflation. It hasn't made its way to the supermarket shelves yet, so official CPI figures are still registering inflation. That's a good reason why governments need to change their way of identifying inflation/deflation so that they get on to the problem sooner.

The combination of economic decline with deflation is disastrous for many reasons. With total output declining, wages need to go down in real terms. Deflation means that wages are rising in real terms, and this can be very hard to renegotiate. The result is rapidly rising unemployment and companies going broke. Another problem is that companies are unwilling to sell assets preferring to leave them on the balance sheet at an inflated price, thus concealing the loss.

When we have a forced economic decline (and we need to get used to that) then we would like to have that run smoothly, with everyone getting poorer together. Deflation prevents that, causing the economy to seize up. Deflation is actually easy to fix, but the important thing is to do it in a way that addresses the underlying problems rather than the symptoms.

It is crucial that independent central banks, not politicians, address deflation, just as they have the job of preventing inflation. The solution to deflation is to print money and spend it. However it should be done in ways that (a) are reasonably fair and automatic; and (b) is to a large extent reversible when inflation reappears. It is also sensible for the government to requisition some of the printed money to spend addressing the underlying structural problems which lead to the economic decline.

Printing money is a tax. It is used by all governments in war time because it is so easy to collect. It is a tax on people holding money and on lenders. Because it is a tax, the central banks should provide the printed money to government for spending when there is appropriate tax legislation. Other than that it should be constrained to spend the money in an automatic way that is reversible. In America the Fed buys up outstanding government bonds. Australia doesn't have any such, and I think even America may not be able to buy enough. Also pumping money into the bond market is a very indirect way of getting it into the general economy. I think the questions of how to reversibly spend the money needs to be considered more. My instinct tells me that the right approach is for the central bank to buy durable stuff that it can expect to sell when the economy picks up. Why? Because this is what an individual in a pre-money society would do to prepare for the future.

In our current crisis Governments need to spend some of the printed money on infrastructure to address the underlying problems, but this will turn into a feeding frenzy of bad decisions if governments are allowed to spend the printed money without the consent and oversite of the legislature.

Capital Destruction

We've seen how reaching Peak Oil requires some process to destroy demand. More important than demand destruction is capital destruction. Here I am referring to real capital: useful physical assets, knowledge and expertise.

When we move to a new technology we destroy the capital associated with previous technologies. A recent example is the move to mobile phones. Suddenly all those pay phones weren't making any money. And it wasn't just the pay phone booths that had lost value: behind that was a whole lot of back office equipment and human expertise. Of course we absorbed that particular capital loss with no widespread pain. Switching from an oil based infrastructure will be extremely painful, even if the replacement is just as good. And it won't be.

The Great Depression of the 30s has been portrayed as being about nothing substantial: just economic mismanagement by Government and Central Banks. However looking back we see that it was a time of enormous change in the underlying infrastructure of the Western world. Energy moved towards electricity, oil and natural gas. Transport moved from horses to motorized vehicles. Communication moved to the telephone. There was massive capital destruction, and the need to build new and different capital. Having said that we can see that things would have worked better if governments had not allowed deflation and perhaps they could have done more to help get the new infrastructure up and usable.

In our current crisis, the capital destruction caused by moving transport away from oil is not just the obvious: vehicles, service stations, mechanic expertise, airports, ... . It also includes a lot of things built on the assumption of cheap transport, particularly the Western world's sprawling suburbs. When we subsequently move away from fossil fuel for electricity generation, that will also destroy the value of a lot of energy infrastructure.

The Underlying Problem

Getting the financial issues sorted out will reduce the pain and duration of the transition. Addressing the underlying energy problem is more important.

The initial problem is the decline in amount and quality of oil produced. Liquid energy has been particularly important for transport. We need to transition as smoothly as possible to alternatives. Boats and trains can transport for much less energy than road vehicles. Train lines can be electrified. Larger vehicles and boats can be run on compressed or liquefied natural gas. Cars can run on batteries or hybrid engines. Large ships could return to coal or even move to nuclear.

This is a huge change in infrastructure. Government will have to lead. Good decisions need to be taken about what to do and in what order.

Following uncomfortably soon we will see the worldwide peak and then decline of all fossil fuels. This is hard to believe in Australia where we have a lot of coal and gas, however there is no doubt that we will sell this, at least to our traditional friends, in an increasingly dangerous world. So the world, including Australia, needs to prepare for a post carbon economy. Of course this is pleasing for Australia which is predicted to be badly affected by climate change. Our chances of co-operation on reducing use of fossil fuels was never good, but it will turn out that the world has no choice.

The bad news is that all our non-carbon options, nuclear and various sorts of renewable, have significant up front capital costs before they then deliver energy with low marginal cost. The exception is biofuel which doesn't seem to deliver net energy at all, and will not be considered here.

As with transport, the government is going to have to take the lead in a huge capital investment during very difficult economic times. There is no room for spin, pork or emotional consideration in determining where to put that effort.

Energy for everything

It seems as if there are many inputs to our modern life, but all of them can be replaced with enough energy. If you want fresh water then energy can desalinate sea water and energy can transport the water.

If we look at any physical thing shaped by human intention or any human activity, then we can see that it was constructed using existing infrastructure plus energy. If we look at that infrastructure we can see that it, in turn, was constructed with previous infrastructure and energy. This can conceivably be traced backwards to when there was no infrastructure shaped by man at all. Energy is everything.

There is one other essential ingredient: Suitably educated humans to utilize the infrastructure.

Energy and Jobs

Energy and appropriately educated humans utilize existing infrastructure to generate directly useful stuff plus new infrastructure:

Note that our productive infrastructure is effectively decreasing because it is tuned to an energy mix which is changing. So total output is going to be reduced till that is fixed. To fix it we need to devote a larger proportion of output to building new infrastructure. So that is going to reduce the amount of useful output even more. And then our productive infrastructure is not optimized for its new job of building this new infrastructure, which reduces its effective size still more.

With the Industrial Revolution, we learned to utilize an easily expandable supply of cheap energy. This leads to ever more sophisticated infrastructure, and a huge demand for educated workers to drive that infrastructure. The relative shortage of workers drove up wages and drove the price of energy down. In the following diagram the icons are set so that a typical activity requires an equal number of people (workers) and barrels (energy):

Because there was plenty of energy, energy prices were driven way down. The fact that energy prices got off the floor over the last few years shows that we aren't in this position any more.

If we get to the point where there is a significant shortage of energy then we might go back to the way things were before the Industrial Revolution, with wages driven to the floor:

This future destruction of the middle class is an additional reason that the middle class needs to wake up politically now. With this sobering possibility in the distance, we will turn to the consideration of what needs to be done.

Navigating to a solution

There are no easy answers. That's why we must look at the process, not just grasp at possible solutions.

The Truth will set us free (or at least give us a chance)

There is this idea that the economic issue is lack of confidence. This is demonstrated in Australia by both sides of politics accusing the other of not talking up the economy. Nothing is more destructive of confidence than lies. Nothing would do more for confidence than publicly identifying the real underlying issue, explaining what is the best we can expect under the circumstances, having a plan to get that best possible result. People will get behind that, if the plan clearly identifies how it shares the pain as evenly as possible.

We don't only need more truth from government to people. We need more information available about what people and organizations are doing. We need more transparency.

The more transparency there is, then the better decisions the markets and governments will take. This becomes much more important in a long period of decline. People are going to be asked and required to make sacrifices. They need to be able to see that everyone else is also making sacrifices.

Since we need to make massive infrastructure changes at a time of economic weakness, we can't afford to make mistakes about this. We can't have politicians picking the most articulate advocate, or the most politically advantageous option. We need independent scientific and engineering teams with strong mathematical skills to conduct an open and vigorous evaluation of the costs and benefits of different options. This has to include substantial powers to investigate the claims of companies with a commercial interest in government decisions. A nice name for this investigation team might be "The Ministry of Truth": reminding us of the novel "1984" and the destructive power of spin.

“Prepare for the future” mode

People are clearly showing that they want to save to prepare for a difficult future. Meanwhile governments want their citizens to get back to normal spending patterns to get the economy back to business as usual. The people are right. We must go into “prepare for the future” mode. But governments can't prepare for the future by saving money, except by the beggar-my-neighbour tactic of saving some other safe currency, and indeed there is no such currency.

To prepare for the future we have to stop spending money on swimming pools, SUVs, eating out, etc. Instead the community as a whole has to spend on new infrastructure for a changed future.

To encourage people to save, and to channel those saving where they are needed it seems that we can learn from war time experience, and issue “Energy Crisis Bonds”. These would logically safeguard the value of the investment in real terms, as a proportion of the nation's wealth. During the period of deflation there will also be money available from unfunded spending (printed money) and that will also be available for building infrastructure -- preferably with the consent and oversight of the legislature.

Clearly switching the working population to different activities is going to cause a lot of dislocation, with massive unemployment having to be absorbed into infrastructure construction. The government will naturally make more labour-intensive infrastructure development choices, because of the substantial cost in unemployment benefits that is already effectively committed for each worker.

Happiness

Research, and common experience, tell us that people will not be less happy when they are poorer, as long as they feel that it is unavoidable, and as long as they feel that everyone is suffering equally. This can not plausibly be achieved without a higher level of transparency into individual wealth than we have known recently. We remember Mrs Bennett in "Pride and Prejudice" saying that Mr Bingley, who she hasn't met, has "five thousand pounds a year". We don't need to get back to that level, but we do need to have real statistical information published regularly about how different groups in society are faring, about asset price changes, and so on. Social harmony will be preserved if government responds quickly when some groups are benefitting unfairly from the difficulties of society as a whole.

Phases of the Energy Crisis

The first phase of the energy crisis is peak oil, and that is happening now. Oil will still be our major transport fuel for a decade and have continuing use long after that. However the steady decline in maximum achievable oil production puts a cap on maximum economic production. When we are near that cap the price of oil will limit demand and initiate further economic collapse. During this phase we are not short of energy, just of liquid fuel, particularly hitting transport. During this phase it is possible to make progress without improving efficiency, as long as liquid fuel use is reduced. For example trams use much less energy than electric trolley busses, but electric trolley bus systems are cheaper and easier to install. Looking at longer routes, trains are much more energy efficient than buses, but it is much easier to set up a bus infrastructure with natural gas powered buses. But choosing the less efficient quick solution should always be done with eyes open, and with a plan to move beyond that choice.

The second phase of the energy crisis will be the decline of natural gas. This will not hit the world uniformly since natural gas is less likely to be transported. The infrastructure for transporting gas is being built, but will not be adequate for a fully global gas market for a long time: so most places without gas will be forced to go to phase 3 early. Natural gas does make a useful replacement as a transport fuel, even though the handling issues are more difficult and potentially dangerous.

The third phase is the decline in coal which will start within 10 or 20 years. We are used to hearing that coal will last for hundreds of years. However already we see that the good quality coal and the easily accessible coal is disappearing. While there is a lot of coal out there, it is not much use if it takes nearly as much energy to get it out and prepare it for use as you get out of it by burning it. The UK provides an example of what we might see with coal production: estimates of coal reserves in the UK were still being given as decades, until just before the coal industry collapsed in the 80s. We also hope to close down coal mining earlier than necessary in order to leave as much coal in the ground as possible, to reduce the level of global warming.

Peak coal is the most important. If we aren't well on the way to non-fossil energy sources by then, the consequences will be drastic. The timing of peak coal is very uncertain. There are other important reasons to want to leave coal in the ground. So moving to carbon-free electricity generation must be given very high priority, nearly as great as the priority we give to dodging the bullet of peak oil by moving to transport options that don't depend on oil derived fuel.

The key thing to understand about phase 3 is that electricity is nice for some things, but it isn't convenient for all things. A lot of energy conversions will have to be done, a lot of batteries will have to be built. You can't just add the current electric energy and the current oil and gas energy use and say "that is how much electric energy we will need". Instead we will need much more than that, just to stay in the same place. This at a time when it is hard to get any sort of power station built at all. Governments are going to have to ride roughshod over local objections to every sort of power station.

Specific Actions

This section is meant to give an idea of the range of possible specific actions to address the Energy Crisis. Different ones harm or help different groups of people. So getting the right plan adopted and implemented expeditiously will require a lot of political energy. The problems will start with the evaluation of options and that needs to be done vigorously and transparently by engineers not politicians. However it is reasonable to expect that many actions can be identified as no-brainers that we can start on immediately. For others we can start on preliminary planning and initial work, without definitely committing to that action.

Transport

If all countries put a huge effort to move away from oil dependence for transport, it won't come soon enough to prevent real problems the next time the world economy gets going again. But the sad fact is that some will make less effort, and oil exporting nations may make no effort at all. So the countries that do make preparations need to do even more:

  • Stockpile oil while its relatively cheap during economic down periods, to release when the price shoots up;
    • Strategic Petroleum Reserves need to be much larger than they currently are. Australia currently has the worst.
  • Convert as much public transport as possible to electricity or natural gas (if locally available), and where that is not possible, stockpile the fuel;
    • Busses and trucks can all be Natural Gas in Australia.
  • Expand public transport, and rail and coastal shipping freight, as rapidly as possible;
    • Now is a good time to buy ships;
    • Busses should have more right of way;
    • Car congestion taxes should be used to keep the roads unclogged;
  • Install the infrastructure to support electric and natural gas vehicles and keep raising taxes on petrol and diesel and on new petrol and diesel vehicles;
  • Remove the duty and quickly fix any unnecessary standards issues to allow the import of electric and natural gas vehicles;
  • Install additional electric generating capacity to cover additional transport requirements;
  • Rezone land near railway stations for medium and high density housing and facilitate actual construction;
  • and lots of other stuff...

Energy

In the short run we need more energy, in order to support transport in various ways, heating, etc. The government needs to lead because, from a business point of view, there is less need for energy during the economic slump. Also alternative and nuclear energy have large up front costs which will be very hard for businesses to raise in the current credit squeeze.
  • Expand existing fossil fuel power stations where possible, to bridge the time gap to non carbon power;
  • Start to plan and build every sort of new power production, combining learning with doing: wind, geothermal, solar, nuclear;
  • Improve the electricity grid substantially in capacity and intelligence;
    • Need high capacity DC links from energy sources (like wind on west Tasmania) to customers;
    • Need to handle variable input better (like wind and solar);
    • Need to allow entepreneurs to safely connect and get reward from electricity generation and storage;
  • Provide government funded oil (and gas) exploration and development while oil prices are low;
  • and lots of other stuff...

Long Crisis Socialism

When there is a real crisis then everyone is a bit of a Crisis Socialist. Wars and economic collapses cause all governments to engage in the sort of economic activities that normally only Socialist governments do. Even George Bush is a bit of a Crisis Socialist: his administration has purchased the insurer AIG and some banks.

Normally it doesn't make sense to describe yourself as a Crisis Socialist since it is only applies in temporary circumstances. This time it's different. The Energy Crisis is going to be a very long crisis, lasting decades, with other environmental and resource limitation issues threatening to extend the crisis. The current financial crisis is the first phase. Ad hoc crisis socialism is happening everywhere, without any understanding of the nature of the crisis. We need to do Crisis Socialism properly: understand the problem, work out what needs to be done, and plan so that things are done in the right order. When we get past the crisis we can denationalize the socialized activities.

Socialism only works when people are in the mood to sacrifice for the good of the community. It works in crises. Preserving the people's good will and support is the essential ongoing requirement. This can only be done with a high level of trustworthy transparency.

Politics

‘what is democracy but the stage immediately preceding oligarchy?’ Aristotle
In the World's current circumstances Socialism is not extremism, it is just an inevitable practical step. There will be plenty of extremist voices in the months and years to come. To resist those calls we urgently need clear headed leadership that can sell the necessary sacrifice to the people.

Dealing with Deflation

Dealing with Deflation


The prices of houses and other fixed assets are declining. The prices of commodities are falling. This is deflation. It hasn't made its way to the supermarket shelves yet, so official CPI figures are still registering inflation. That's a good reason why governments need to change their way of identifying inflation.

The combination of economic decline with deflation is disastrous for many reasons. With total output declining, wages need to go down in real terms. Deflation means that wages are rising in real terms, and this can be very hard to renegotiate. The result is rapidly rising unemployment and companies going broke. Another problem is that companies are unwilling to sell assets preferring to leave them on the balance sheet at an inflated price, thus concealing the loss.

When we have a forced economic decline, and we need to get used to that, then we would like to have that run smoothly, with everyone getting poorer together. Deflation prevents that, causing the economy to seize up. Deflation is actually easy to fix, but the important thing is to do it in a way that addresses the underlying problems rather than the symptoms. More on that later.

Decline leads to Deflation

Deflation occurs when there is less money chasing the available goods and services. Since the available goods and services are going down, it is not obvious why an economic decline leads to deflation. The reason is that money is not just the stuff the central bank prints. For practical purposes it includes credit.

In an expanding economy it is relatively easy to use borrowed money to do things which will bring in more money, or for the consumer to buy now expecting to earn money in the future to repay. In a declining economy, and particularly when switching from expanding to declining, we see that loans go bad, wiping out credit, and then lenders are unwilling to lend and borrowers are often unable to roll over their debt.

There's a chicken and egg problem here. To a large extent it is the deflation itself that stops lending, which in turn leads to more deflation. Only the first few percent of the current decline was caused by the contracting oil supply.

Why does deflation stop lending? I remember when I had a young family I bought a house on borrowed money. Then, after a bout of inflation, I was lucky to be able to repay it with much less valuable money. Deflation has the reverse effect. If you borrow money then you have to repay a larger amount in real terms. If you are trying to run an enterprise and you borrow money to buy the inputs, by the time you have a finished product to sell its price has gone down. Inflation hits those lucky enough to have money in the bank, but deflation hits the most vulnerable and the most productive.

Inflation makes real interest lower than nominal interest rates. Deflation has the reverse effect, making real interest rates higher than nominal.  This is a problem for central banks, which try to stimulate the economy by reducing nominal interest rates, and they can't reduce nominal rates below zero.

Printing money

Deflation is easy to deal with. Just print enough money. It is hard to do this without distorting the economy. Even when you do want to distort the economy in a particular direction, it is a mistake to go too far, and most of the created money needs to be distributed in a way that does minimal distortion. More on that in the next section.

The next problem with printing money is that the extra money will tend to cause inflation as soon as the economy bottoms out and credit starts to rise again. So money needs to be put into the economy in a way that is substantially reversible. However it would be a good idea, particularly in our expected peak oil economic decline, to not allow the huge credit expansions of the past. This is what many advocates of sound money desire, but they want to get there by allowing deflation to run its course, and that would be a catastrophic and unnecessary mistake.

When governments print money they do it as a loan from a magic account, which then goes negative, to the spending agency. Repayments to the magic account represent money being "burnt", the reverse of "printed". It is important to understand that this is not a real loan in any sense. It is not "this generation spending money that furure generations will have to repay" or anything like that. Printing money is all about the here and now, and not about the future. It is a tax on people holding money and on lenders. It is the easiest tax to collect, which is why it is so popular in war time.

An alternative way for governments to raise money is to really borrow money, by selling bonds. This doesn't normally counteract deflation. However when people are just holding on to money, then that is deflationary and government can counteract that by selling ultra-safe bonds to soak up that money, then spending it. America particularly needs to do this because they buy a lot of oil and other stuff without sending equivalent amounts of goods and services in return. They should try to stop doing that, but until then they need to provide somewhere for all those dollars to go. Since the oil exporters and other savers have lost confidence in commercial opportunities it is necessary for the US Treasury to borrow that money so that it has somewhere to go, so that the wheels of commerce don't grind to a halt.  The $700 billion expansion of US borrowing won't be enough. Now borrowing money like that really is a debt that future Americans will repay. However Americans worry unduly about this since they can obviously print money to repay the loan if necessary. This is not an option for most countries whose loans are denominated in a foreign currency, normally US dollars. Argentina might go broke and default, but the USA never needs to.

How to spend printed money

As with inflation, preventing deflation needs to be a central bank job, not a government job. Since the solution is to print money and spend it, the politicians would spend it on vote buying and that would distort and destroy the economy.

It is also wrong to do what we are seeing worldwide: Giving money to banks and encouraging them to lend it. This is an unjustified gift to bank shareholders and bondholders, and success would be just another credit bubble.

Deflation happens when people are sensibly battening down the hatches and preparing for the future. The government has to respond to this by shifting economic activity to things that will be useful in the expected difficult economic future. The matter needs to be given careful consideration and modelling. However to me the likely best answer seems obvious:

The central bank should counter deflation by printing money and spending that money to buy and store durable commodities. This has multiple positive effects:
  • It puts money into the economy to counteract the shortage of money caused by the collapse of credit;
  • It keeps up the price of those commodities and hence the products that are derived from them, counteracting the decline of prices;
  • It can be done in a fairly automatic way, with purchases being done to preserve normal relative levels of production uniformly across all durable commodities;
  • When the economy turns and there is a need to soak up that extra money put into the economy before it causes inflation, then all that needs to be done is to sell the commodities. This is doubly anti-inflationary since it soaks up the money and reduces the price of the commodity.
  • Stockpiling useful commodities really is a good way to prepare for various future difficulties such as wars and natural disasters interfering with supply.

Critics won't mind this when the commodity is produced locally. However it is important to cover the range of commodities evenly so that the central bank can do it in a very automatic way, just like setting the interest rate. In may ways it is even more important to stockpile essential stuff that can't be sourced locally.

When the central bank prints money and buys commodities that are sourced overseas then the local currency has to be converted into the sellers currency. This takes place in the currency market. The effect is to reduce the value of the local currency relative to others. This makes exports more competitive and imports more expensive. The import of the purchased commodities has to be matched by higher net exports (and/or higher foreign investment). Either way the money that seems to be spent on foreign stuff actually finances an equivalent amount of local activity.

Summary

Central banks need to have the job of fighting deflation as well as inflation. To do this they need to print money and pump it into the economy in a reversible way so that it can be removed when inflation reappears. A simple an automatic possibility will be to use printed money to buy and stockpile (and later sell) durable commodities in their normal ratio of use.

Garnaut and the Peak Oil Tsunami

Garnaut and the Peak Oil Tsunami

Describing Peak Oil as a tsunami is actually a good analogy that goes beyond the scale and destructive power, here's why: In a tsunami an earthquake under water rapidly displaces water. But it can't spread the displacement of water across the whole ocean, so it does a larger local displacement. Then that raised water collapses spreading a wave of high water rolling outwards, followed by a trough, and so on. These waves constitute the tsunami. In the case of oil production we find that supply is unable to grow, being near its peak, while demand is increasing, so the gap at any given price keeps rising. If this gap had arisen slowly then the whole economy would slowly adapt. However it has arisen rapidly. So the price of oil has had to overshoot, rising enough to kill off the sort of demands, like vacation driving, that can easily be foregone. Meanwhile many businesses are continuing that are not viable at this oil price. They are just continuing on momentum and hope and existing contracts, and continuing to consume oil. What then happens, as we see throughout the world economy, is that those businesses die or contract. And since the oil price rise has overshot, this demand destruction will soon cause the price of oil to start falling. This will in turn overshot in a downward direction, resuscitating demand. This will then interact with the worsening supply problem to cause a new bout of demand destruction. So we see that the destruction of demand, that is necessary to bring demand into line with the long term decline in supply, will occur in waves. Each wave first hits the most easily destroyed demand, but reaches out to touch the whole economy.

If, as many have speculated, the recent increases in energy prices are already enough for us to meet our carbon emission targets, then there will be more emission certificates issued than are actually needed to meet our targets. So the market price of emission certificates will rapidly fall to zero, and there won't be any additional burden on the public. The Garnaut scheme is sufficiently flexible that we don't have to worry about whether it might be unnecessary. We must, however, look more deeply into the question of how peak oil and its related problems interact with carbon mitigation.

Some of the people who predicted the timing of Peak Oil so exactly, starting with M. King Hubbert in 1956, have also looked at natural gas and coal. Their deduction is that there is much less than is commonly supposed. The people who said until recently that there was no chance of an oil shortage, are the same people who say that natural gas and coal will last a very long time. Some of those who have been proved right on oil, believe that we will see the world peak of natural gas in 10 years and the peak of coal production in 25 years. Even the lowest scenario for carbon emissions in the IPCC report will never materialize, so the world temperature rise won't exceed 2 degrees (barring unmodelled positive feedbacks). It would however be nice if we could make the temperature rise even less.

The whole thrust of the Garnaut report is on reducing the rate of emissions worldwide to be aligned with the ability of nature to absorb that carbon. We can now see that that isn't going to be a problem. From a point of view of reducing the impact of carbon emissions the issue moves to this: As we move inevitably to a post fossil fuel era, can we leave some carbon in the ground? Clearly if, as I am convinced, those predictions are correct about peak natural gas and peak coal, then the world needs to move very rapidly to a post carbon economy. If we sensibly leave a bit of margin for error in that change, by moving more quickly than is entirely necessary, then we will, as a consequence, leave some carbon in the ground and suffer less climate change.

Garnaut encourages Australia to take the lead in mitigating climate change, since the modelling suggests that we will be the worst sufferers. Other countries are less negative about warming. Russians are publicly licking their lips. The Canadians are too polite. Many countries are too poor to consider any sacrifices. Garnaut himself has expressed pessimism about the whole enterprise. But the world has to respond to peak fossil fuel to lead us to a post carbon energy environment. If we do that as fast as we possibly can then we're still more likely to be late than early. If we're early and manage to leave some carbon in the ground that will be a bonus. If you're worried about climate change but don't actually believe that fossil fuel will peak, I'd still urge support for a world wide campaign to address peak fossil fuel, because that is more likely to actually move the world off carbon than appealing to moral sentiments and good will.

The aims of climate mitigation and overcoming peak fossil fuel are better aligned than they seem to be. Let's look at the two most obvious conflicting cases.

  • Oil is running out first. It is the world's main transport fuel. Compressed or liquefied natural gas is a good replacement. In the circumstances it is a bad idea to burn natural gas for electricity instead of coal. As Matt Simmons says in a recent presentation "Natural gas is our most precious fossil fuel". Carbon trading (or tax) oriented to reducing the rate of emissions may force a switch to gas. However if, as indicated, the gas will soon peak, then we will get back to burning the coal later. If you see the aim as leaving carbon in the ground then the advantage of switching to gas to generate electricity is much less, if any.
  • There is a huge worldwide infrastructure for liquid fuels for transport: most particularly the existing vehicles and service stations. We can't magically switch all that to natural gas and electric in a short time frame. One way to preserve the value of that infrastructure and reduce the economic impact of peak oil is, during the transition, to do some conversion of gas to liquid (GTL) and coal to liquid (CTL). This requires energy, so the quoted figures show high carbon emissions for this process. This is exaggerated however, because the energy source doesn't have to be a fossil fuel one. One needs to also consider the cost in energy of moving the infrastructure away from liquid fuels more quickly, if we don't do GTL/CTL.
Garnaut is an economist and assumes, I guess, that the magic of the market will produce a replacement energy source. It will be wise to be more proactive and to move forward with an option we know will work, even if that doesn't end up being the economic winner. Many people are hoping for coal combined with carbon capture and storage (CCS). That is not going to work if CCS fails or if the world runs out of coal, and I expect both of those things to happen. It is hard for renewables to fill the whole bill because they are intermittent and their huge scale inevitably involves significant ecological impact. I have high hopes for geothermal, but the limitations and costs of drilling technology suggest that this won't be universally applicable.

To me it is clear that the core energy infrastructure for most of the 21st century will have to be nuclear power. If it is inevitable, then let us get there as soon as possible and leave some carbon in the ground. There are many wild claims about this. Some say it is not price competitive. In that case it won't happen, and a lot of dispute will be unnecessary. With modern reactors the available uranium and thorium will last a long time, and there need not be a problem of very long term waste. Nor are modern reactors useful for making real atomic bombs. It would also be possible to site nuclear reactors in safe places and generate other fuel in various ways: e.g. hydrogen from water. Australia would be such a safe place, geologically and politically.

The question of whether Nuclear Power is necessary or not is one of fact. There are many other important questions that need to be answered. We need to get past politicians believing the most plausible experts and pandering to voters special interests. We need open vigorous expert well funded impartial investigations of the facts by people with mathematical skill. As Professor David MacKay says: we need numbers not adjectives, modelling not arm-waving. Prof MacKay is head of the Inference group in the Physics Department at Cambridge. I urge everyone to read his book on sustainable energy which is available free on the Internet at withouthotair.com.

We are running out of fossil fuel. This is the immediate problem that we need to address. Luckily doing so will address climate change more effectively than worldwide cooperation and goodwill were ever likely to do.

ECAL posting

The previous post is from a google doc: http://docs.google.com/Doc?id=dg7nkx7d_41g5zrpx8k. I don't know why it decided to make H3 headings bigger and brighter than H2. I'm looking for people who roughly agree on proposed policy. to discuss the possibility of forming such an organization. Mostly in Australia, but if people want to do the same elsewhere it would be a good idea to have an umbrella organization. If you're interested in joining, please comment in this post. If you want to disagree on my policy items please comment on the previous post.

Energy Crisis Action Lobby

Energy Crisis Action Lobby

Political response to the Energy Crisis is misguided. This is a matter that affects everyone. The Energy Crisis Action Lobby (ECAL) is an organization of like minded citizens to press for a recognition of the seriousness of the crisis, and to urge the rapid implementation of valuable policies. ECAL's membership consists of citizens that support 3 specific policies:
  • Continuous vigorous well funded open investigation of all relevant facts, led by mathematically expert scientists and engineers.
  • Actions to address the Energy Crisis will incidentally address climate change, but additional actions to address climate change can not be sustained during the crisis.
  • Nuclear energy is the essential core energy source for a world without fossil fuel.
Many other specific policies and actions are needed, and ECAL will participate in the debate about the possibilities. These need to be subject to vigorous and continuous assessment. We can't afford too many more mistakes (such as using ethanol from agricultural land for transport fuel). A forth principle is implicit in the educational aims of ECAL: Voters need to be fully informed and made aware of the inevitable sacrifices. ECAL has complete confidence in the willingness of the people to work together to solve this crucial national and world wide crisis, as long as they are fully informed and confident that the sacrifices will be shared.

Characterization of the crisis

There is a limited supply of fossil fuel and it is now running out. Currently oil producers are unable to expand supply and supply will decline very soon if not now. Peak natural gas will follow within 10 years and peak coal within 25. Demand would be expanding rapidly now if prices had stayed low. The price has to rise high enough to destroy that incipient demand and more, to make supply and actual demand balance. This demand destruction will reduce the output of the world economy. This is not like previous economic contractions which were part of a cyclic financial process. As such it will continue, and continue to worsen, until we rebuild the economy with new infrastructure based on new energy sources. So the rise in the price of oil is not caused by a bubble, or by speculators. It can't be fixed by government action, other than moving to different energy sources. It isn't likely that there will be a complete collapse of civilization as some predict, but if that were to happen then it is impossible to see how industrial civilization could ever get going again without the surface coal and oil oozing out of the ground that fueled the initial rise to our current industrial state. Our failure to heed many warnings, starting with M. King Hubbert in 1956, means that we have no chance of escaping a serious economic contraction which will likely far exceed that of the Great Depression. Managing that contraction fairly and optimally, so that we can emerge from the other side without collapse, is the business of all governments over the next 40 years. Business as usual (BAU) is over. Keeping the voters uninformed to prevent panic is highly counter-productive. We need debate, we need open investigation and analysis, and we need action, but all action needs to be kept under review so that the inevitable mistakes (such as biofuel from food) are not continued.

Intensive open investigation of technical issues

There are many important technical debates which will shape the way we respond to the energy crisis: How quickly will oil exports disappear? How will that affect the availability of other things like fertilizer? How will the economy respond to shocks? Will algal biodiesel save the day? How long will natural gas last? Should we go through a phase of compressed natural gas vehicles, or go straight to electric? And many more. Currently these debates get carried on in an academic style where people express a detailed opinion, but rarely respond to those with a different point of view. Also a lot of important information is hidden as trade secrets. It is crucial that planning be put on a less haphazard footing. We need mathematically competent experts to conduct open enquiries on these and other important matters. They need to be able to bring opposing parties together to find the core of their disagreement. They need to be able to extract important information where necessary. They need to be able to fund research to shed light on crucial technical questions. These investigations need to be conducted by mathematicians, or by scientists and engineers with strong mathematical skills and insight. As Prof David MacKay, head of the Inference group in the Physics department at the University of Cambridge has said, we need numbers not adjectives, modelling not arm-waving.

Global Warming action is not a short term priority

There are 4 reasons why economic action to address global warming is not appropriate now:
  • The amount of fossil fuel that can be economically extracted and consumed is much less than feared in the IPCC and other reports. Even the lowest option considered by the IPCC is more than will ever be burnt.
  • We have already had the price rises for fossil fuel needed to foster efficiency and alternatives. And indeed even higher rises are coming. There is no need for specific carbon taxes as well.
  • Government action to address the Energy Crisis will also mostly addresses CO2 emissions, and it will do so with much greater universality and urgency than would ever have happened to prevent the less immediate and less desperate issue of climate change
  • This mega oil shock is going to cause immense economic pain throughout the world. Until that is reversed there is no chance that governments will impose extra pain to address global warming.
Of course scientific understanding of the climate still needs to be strongly supported.

Nuclear Energy is a crucial part of the global solution

While we have high hopes for renewable energy, particularly geothermal and solar-thermal, still their scalable effective operation remains to be seen. Corn-based biofuel has been the first major renewable to be brought on stream. With high use of mechanized equipment and fertilizer it doesn't produce significant (or perhaps any) net energy. We can't afford to waste too much effort on such mistakes. There are plenty of potential issues with each of the other renewable energy sources. We mustn't step off the cliff into a world without fossil fuel without initially having substantial nuclear energy up and running. Modern nuclear energy is very reliable and fails safe. By moving to breeder reactors and utilizing Thorium as well as Uranium it is possible to make the existing mineable resources last a long time and not produce long-lived waste. Australia, with lots of sunshine and geothermal potential, might survive on renewables. However we will be a major supplier of nuclear fuel, we need the world to get its nuclear act together, and we have a particular reason to want the world to switch to the safer thorium since we are likely to be the major exporter of that. So we have good reason to get experience building and running modern nuclear reactors. Maybe voters will not allow these near population centres. However if the economy goes as bad as expected, then communities will be pleased to have the work and other industry that comes with them. Prof David MacKay, head of the Inference group in the Physics department at the University of Cambridge, is writing a book on sustainable energy, based on his principle of "numbers not adjectives". When he first started his investigation he was anti-nuclear. However he discovered that Britain can not be supplied with energy without incorporating a significant nuclear component.

Possible Actions

There are a lot of practical actions that can be taken to reduce the impact of the energy crisis, and to try to overcome it. Many have an energy cost and we must choose wisely which to support. The following list is illustrative, not exhaustive:
  • Lower speed limits and run an education campaign on saving petrol when driving.
  • Build infrastructure for Compressed Natural Gas vehicles, and/or electric vehicles.
  • Stop putting money (and energy) into road building.
  • Enhance rail: new routes, new rolling stock, electrification.
  • More CNG buses with more bus lanes and other right of way.
  • Shipping: LNG fuel? Docks integrated with rail as well as trucks.
  • More support of energy and transport research.
  • Build big parking stations near railway stations.
  • Make suburban trains more freight friendly.
  • Forcibly rezone land near railway stations for high density.
  • Stop plans to burn natural gas for electricity, since it can replace petrol/diesel for transport, so we mustn't waste it.
  • Develop, with the help of India and the US, a plan for nuclear energy. Implement it.
  • Help India to get to a nuclear future based mostly on Thorium. Partner with them and with the US to provide this to the world, using our large Thorium deposits as the fuel source.
  • Build large solar thermal and geothermal power stations so that we can evaluate their potential for large scale reliable energy.
  • Keep using low quality coal for power generation (since we can't afford to switch to gas), and exporting the better stuff. We also need to export natural gas to the world, which will be hit much harder by the Energy Crisis than we will. We need to keep enough to complete our transition to a post carbon world.
  • Build gas to liquid and coal to liquid capability, to extend the useful life of the massive infrastructure supporting liquid transport fuel.
  • ...
There is no shortage of things to do. With the money from our net energy exports we should be able to keep employment high through the crisis. We should take advantage of worse conditions in other English speaking countries to bring in people with useful skills and expertise. Because Australia is a net energy exporter our position is far better than most. However we are unprepared for peak oil which is happening now, and we are an oil importer. Also the greater collapse of our trading partners will harm us. Increased international transport costs will also be a problem because of our remoteness.

Additional Notes

Building the nuclear future

Currently nuclear power plants are one-off constructions designed then run by highly qualified staff. This will make it hard to expand nuclear energy rapidly enough to replace declines in fossil fuels. This can be overcome by building smaller nuclear plants which are identical and mass produced to exact specifications and which run automatically in a fail safe way. There are many groups working on this and there are no overwhelming technical issues. The most viable designs use thorium and cannot be subverted for military use without the sort of time consuming effort that would raise alarm bells and be easily circumvented.

Climate Change issues

Here are some things that the people worried about climate change will argue for:
  • No GTL/CTL. Response: The quoted values for CO2 emissions are exagerated. You need energy to do the conversion, but that energy can come from nuclear/renewable sources.
  • Replace coal with gas for electricity. This wastes the fluid advantage of gas which makes it suitable for piping and for transport. We can't afford to do that.

Energy conversion issues

Nuclear and renewable energy will mostly be in the form of electricity and heat. This has to be converted to be useful for transport. Batteries convert electricity to chemical energy. Or we can use energy to create fluid fuels. For example you can use energy to get hydrogen from water, then burn it later to get the energy. There are lots of choices, but the common fact is that you need a lot more energy than at present because a lot of energy is used in the conversions.

Investigation details

The need for nuclear and the lesser importance of climate change action are based on a particular view of the facts. These facts would also be up for investigation by the proposed continuous open investigation. The key characteristic of the investigation teams, in addition to their ability to understand mathematical aspects of scientific work, will be a willingness to change their mind and admit to having been wrong when their are new facts or improved modelling of other analysis of the situation. This will be improved by minimizing the extent to which they reveal their own opinions during the investigation, or identifying themselves in conclusion documents.

Managing economic decline fairly

It is a human characteristic to take risks to avoid a loss, even a small loss. The farmer risks injury to stop people stealing apples from his tree. This might be irrational on a single occasion, but it is necessary on a long term basis. On the other side of the coin people are happy to make sacrifices in a common cause when they feel that others are doing the same. So it is essential that the coming economic decline be managed by tapping into that latter characteristic. Otherwise we'll get violent protest, as we have started to see already. The way to achieve this is with a high level of transparency. Currently remuneration is private. This has allowed the high level managers to capture most of the extra income during the recent boom, and lower ranks have been tolerant as long as they were making some progress, or had the opportunity to do so. This will not work during the coming decline. Resistance to ad hoc wage cuts will make it hard for businesses to survive. What is needed is government managed transparency about incomes, and coordinated cuts in incomes by all, falling more strongly on the higher ranks. These coordinated cuts might be in a single business or industry, but it might also be necessary at times to do it nation wide, to maintain the general level of employment. Higher levels of transparency are also needed to facilitate business planning during economic decline. Parts of the economy are interconnected and there needs to be coordinated planning to change the way the economy works. For example currently trucks take things from pickup to final destination. This may well change to using trains and shipping in the middle for longer movements. This can be achieved by allowing blind economic forces to take their course, but it will be better if there is some government coordination of the change, with involvement of the participants. Truck owners, small farmers and many other people needed to be helped through the crisis, even if in some cases it is just to help them see that their business is not going to continue to be viable.

Peak Carbon and Global Warming

I have lately been obsessed by Peak Oil and related stuff (Peak Gas, Peak Coal, etc). I've got to stop worrying about this stuff because it is time consuming and there is not much I can do about it. So here's my summary, to get it off my chest.

Huppert predicted in 1956 that US oil production would peak in 1970. He was derided but was almost exactly right. He predicted world production would peak in 2000. It is currently plateauing, only slightly late. However nobody seems to talk about a very big difference between US peaking and the world peaking. When the US peaked, it started importing, but the price wasn't much affected. When the world peaks the price goes up, potentially quite a lot, as we see. This means that a lot of things start to happen:

  1. People use less (vacation travel the first to go).
  2. Exploration goes up (though there probably aren't any more big oil fields with cheap production to find).
  3. More expensive recovery techniques can be used in existing and restarted oil fields. This includes using nuclear power to extract oil from Canada's tar sands.
  4. Gas-to-oil and coal-to-oil technology becomes profitable. [Gas-to-oil is insane with peak gas not far away, but coal to oil is bound to be important, despite the impact on CO2 production.]
  5. Substitutes come into play: electric cars, nuclear energy, renewable energy.
These things take a while. In the short term all these things are likely to be swamped by a global recession. Unfortunately that will reduce demand for all energy and prices will, temporarily, fall. This is where it is very important for government to step in and do what it can to encourage all the processes above to continue during the recession.

America will pull itself out of the recession by energetically going back to making real things and doing real things, not just shuffling money around. In particular they will drive the development of the energy industry. One only has to look at how quickly they ramped up ethanol production given a little incentive. In particular I expect them to lead the push to nuclear energy, thermal solar energy, and electric transport.

There is a vast oil-based transportation infrastructure. We can't turn it around on a dime. Oil for transport will continue to dominate for the next 15 years even though the consequences of expensive transport will be horrible:

  • A return to more locally produced and more expensive goods and food.
  • Economies that work less well, so that everyone is poorer.
  • Everything that uses oil for raw material or transport is more expensive, particularly food.
  • Much less tourism, particularly global.
  • Sea transport is favoured, then rail. Truck transport will be for shorter hauls. Much more messing around getting stuff between different media types: more use of containers/etc.
  • Much reduced jet travel, some return of propeller planes.
The pressure will be on because production of oil will not keep pace with demand, and may decline. So the price will rise inexorably, except when financial systems fail and there are periods of widespread economic collapse. There needs to be a lot more thought about how to manage periods of economic decline without revolutions, wars, starvation, etc.

Prices are already at the point where nuclear energy and solar thermal energy are competitive with coal. The demand for coal for coal-to-liquid will make it even more expensive. So we can move beyond a carbon based economy starting now. This is an unbelievably huge project. It requires us, the whole world, to put a very large fraction of our productive resources into it, at a time when our productive resources will be severely constrained by the growing cost of oil (shortage of oil). But we have to do it, because if we haven't got there when the oil/gas/coal runs out then the bootstrapping process to get back to prosperity will be very hard. It will be done because, with high energy prices, there is money to be made by doing it.

Many people think that catastrophe cannot be averted. Certainly it is hard to have faith in politicians:

  • Cheney and Bush were well aware of peak oil before elected, and their response has been Iraq and food-to-fuel.
  • Australia has just elected an anti-nuclear government.
  • Windmills and solar energy use a lot of steel.
  • Nuclear industry is limited by shortage of expertise and perhaps some essential materials and capabilities.
Still I think we will be ok on non-transport needs and we'll survive the transport problems with a bit (or a lot) of belt-tightening and localization. I'd certainly like to see economic models that confirm this with non-optimistic projections for oil production. The economic theory that increased prices must produce supply does NOT apply to a finite resource like oil. Does the Treasury know this?

Which brings us to global warming. The good news is that there is not enough carbon in the ground (that can be extracted for less energy than they produce) to cause the extreme CO2 rises sometimes considered. It can't go over 500 ppm. The bad news is that the inertia of the vast petrol/diesel transport infrastructure means that we will use more carbon and generate more CO2 than economic fundamentals require (given nuclear energy). In particular there is no way to stop a lot of coal-to-oil production. Even if Australia didn't do it, and we didn't allow our exported coal to be used for it, still our exported coal would just displace other coal that was used for it. Better if it is done as cleanly as possible in Australia.

So there can't be reductions in CO2 emissions between now and 2020. Impossible. The serious economic problems that will be faced between now and then will make extra carbon charges impossible to maintain, and also unnecessary as the natural price of carbon will be enough to encourage everyone who can get off it to do so. The government's job is to plan and to push ahead of the market. Build nuclear and renewable energy power stations, and sell them. Build railways and ship docking. Get into ship building.

Beyond 2020 there will be huge reductions. 90% by 2050 is guaranteed. We just hope the reductions will be because of a smooth and prosperous switch to nuclear and renewable energy, and not because of global economic collapse.

Government for the nation not the marginal seat

Let's kill too ugly birds with one stone. The first ugly bird is the election of governments with a minority of the two party preferred vote. The second ugly bird is the way money is thrown at marginal seats, particularly at election time. We want to preserve the essential electorate-based nature of the House of Representatives. This creates a house where Government usually has a workable majority. So the proposed solution has the following structure:
  • Most members are elected from single party seats;
  • A small number of additional members are selected (by single transferable vote as described below) to ensure that the balance in the parliament is determined by the will of the total electorate;
  • Minor parties don't get into the lower house this way because only parties that win 2 or more electorates outright then participate in the further distribution of votes to add extra members. If you want to see minor parties in the lower house, that is a separate issue, but probably most Australians don't.
Suppose that we have 140 electorates, but we have 150 total seats. To some extent this system will be run as if it is a single seat returning 150 candidates by single transferable vote. So a quota is 1/151 of the total vote.
  • However first each of the 140 electorates elects one candidate with half the vote in that electorate, which is approximately 1/280 of the total voters.
  • In the context of the single national electorate, votes from losing candidates (and votes from winning candidates beyond the 1/151 quota) are distributed to other winners in their party to get them up to a national quota.
  • If a party doesn't get enough transferred votes for all their winners to get a 1/151 quota then those extra winners get their votes from nowhere, just reducing the value of all other remaining votes.
  • That process also applies to independents in the (likely) event that they don't get a 1/151 quota in their only seat.
  • At this stage there are 140 of 150 quotas taken. So the remaining votes are distributed to create 10 more quotas using additional lists of candidates supplied by the parties. Parties which have not won two electorates just get any extra votes for that party transferred without consideration of whether they would have got more quotas.

75%-baked: Only Live Music

I have various half-baked ideas for making money, but I reckon this one is 75% baked. It would definitely attract a significant following if it got going. The problem will be how to make money out of the popularity. Perhaps sell it to google, like YouTube.

The day is fast approaching when all radio and video will be delivered over the Internet. You pick a radio station by clicking an icon on your PDA. As we see on YouTube and many other places, this opens things up to the amateur contributor.

Another trend we see is the return to live music. Why do we have shows like "Australian Idol"? Because the whole point of music production is for the performers to show off their natural talent and for the audience to evaluate the performers. Music produced by electronic trickery in studios is increasingly recognized as comparatively empty.

It is possible to stream live sound over the Internet today. Internode is leading the way in Australia: http://www.internode.on.net/radio/. Many of the network providers can do this very efficiently using multicast. So my idea is to start an internet radio station providing only live music. It would later be split into multiple stations providing different sorts of music.

Initially it would be all free with amateur sound engineers and performers not paid. Later some extra channels would be supported by advertising or require a subscription (or both), and those channels would pay production staff and performers, not to mention management. Initially expenses, including some payment to management, will attempt to be covered by subscribers who will be able to vote on which acts they prefer to hear.

The station announcement between performances is "This is OLM: Only Live Music. We don't believe that recorded music is real music, and now you don't need it because OLM streams live music, produced with analog devices, 24 hours a day. Recording OLM performances is not permitted and detracts from their intentionally transient and contemporary nature. This doesn't prohibit technical aspects of streamed radio transmission such as the necessary cache delay. If you miss something then encourage the performers to do OLM again. And become a paid up subscriber so that you can vote on which performers you want us to feature".

The assertion that only live music is real, is a marketing position. It is designed to annoy and make people talk. Participants don't have to agree with it.

The key to OLM is to broadcast performances from different time zones around the world. This can be as simple as a solo performer with a good quality microphone broadcasting from their own home. However it will be better to broadcast actual live performances from venues. That requires some sound engineering, though these days that can be just multiple microphones feeding into a computer running some sound software.

Obviously OLM needs lots of people around the world. The sort of things one needs to do to achieve this are:

  • Set up discussion forums for interested people: a wiki and a blog seem likely to be a good start.
  • Put information on the wiki pointing to anything that can be found out about how to broadcast music on the Internet.
  • Look for support from useful people. Simon Hackett the head of Internode has been involved in Internet multimedia for a long time and might well be interested -- I remember him demoing listening to California radio from Australia, including remote tuning using SNMP.
  • Communicate with groups where interested people might hang out (without spamming too much), to invite them to join it.
  • Start practicing broadcasting music, preferably as early as possible from different places around the world, to see how well it reaches.

My view is that if some major ISP owner was interested to be part of it then all the technical issues would be addressed. I also think that OLM would attract amateur sound people and musicians willing to work for no payment if the technical issues were sorted out.

2005/03/24: The Case for a Human Future

I attended a talk that referred to trends and extrapolated them to talk of people living much longer than before, and of intelligent robots that surpass our abilities.

Humans are the most amazing thing that has happened in this universe. David Barrow summed it up neatly in the title of his book: "The Universe that Discovered Itself". The idea that the human story should end and be replaced by a superhuman or nonhuman world is something that people are too willing to accept: even otherwise intelligent people.

The first point to make is that there is not a requirement for change to make way for progress. Humans are tool users. Humans with intellectual and communication tools provided by Information and Communication Technologies are not limited in what they can achieve (relative to computers or improved humans).

There is an idea in the populace that when computers pass a certain level of intelligence they will magically acquire motivation. This is not the case. Our motivation comes from our genes. Our genes have motivation but it is not the same as ours. In the simplest example: If I or my identical twin brother is going to drown, then my genes don't care which. Genes give us complex motivation in which the desire to live and the desire to reproduce are only the most trivial parts. But the fact that genes, even in the simplest bacteria or virus, display clear though unconscious motivation shows that motivation is unrelated to intelligence.

Sure we could give our little machines motivation. We might accidentally give them enough motivation to wipe us out. What we couldn't do is give them the sort of subtle motivation which genes supply that keep us striving to understand, to explore and to conquer the universe, while at the same time perpetuating ourselves and living fascinating lives that we turn into literature and other art. In fact I'm certain that any motivation that us junior gods could bestow on our creations would grind to a halt very soon after we became unable to guide it.

And losing the ability to lead is the great danger of this inhuman or partly human world. If people start living for ever then we will quickly lose the input of youth that keeps human society fresh. The replacement of humans with computers and robots in positions of any importance will lead even more quickly to the loss of humanity's spark.

If machines were given motivation that would make them independent of humans then that would be a terrible crime which would hold the seeds of our destruction. Any motivation less than that would be sufficiently weak as to be no motivation in the big scheme of things.

There is no choice to a human future. The hard bit is to understand what that means in a world where many people have ignorant plans to change humanity. Our present life has already acquired features which will drive evolution towards something which is not fully human.

The "Maximum Estate" tax

It would be better to tax wealth than income, but that is not easy. It would be better to get more tax from death duties, but that is not popular with voters. It would be particularly nice to raise more tax from criminals. I have a simple plan.

Tax payers have to specify to the tax office their Maximum Estate. When they die, if their estate is larger than their last declared Maximum Estate then that excess goes 100% as tax. So there is a strong incentive for those who want to leave money to set their declared Maximum Estate fairly high.

On the other side of the coin there will be a small tax, less than 1%, on the Maximum Estate value. This is effectively a wealth tax.

Even more importantly there will be a hefty tax on changes to Maximum Estate beyond income. So if your taxable income in a year is $100,000, but your Maximum Estate value goes up by $150,000 then the extra $50,000 that appeared from nowhere will be taxed at something like the maximum income tax rate.

Different people will make different decisions about where to set their Maximum Estate. Some will leave it at 0, effectively leaving all their money to the nation when they die. Others will pay as they go. Either way it will be a very progressive tax that will be effective against criminally acquired wealth.

2005/03/15: I hate fake conservationists

Conservationists are too nice. They let all sorts of fake conservationists string along under the conservationist banner. This is leaving the voters confused.

Firstly: animal liberation and the protection of specific animals from human action, has nothing to do with conservation which is about the protection of species and ecosystems. Indeed animal protection is often at odds with sensible conservation. We don't cull koalas or fruit bats even when they are destroying endangered plants. We don't cull kangaroos but insist on letting them destroy their habitat and then starve to death. We don't allow kangaroo farming, so farmers are forced to continue with sheep and other things that destroy the Australian environment. We need to meet this sentimentality head on when it conflicts with the desire to manage the environment well. And we particularly need to denounce attempts by animal rights people to claim to be conservationists. The idea that the way to save animals is to not kill them is something that appeals to children and we need to forcefully say that habitat loss is the overwhelming cause of the loss of species, ecosystems and diversity. [Which is not to say that there is anything wrong with people pursuing animal welfare, I'm only complaining about those that claim that this activity is conservation.]

A second group think that conservation means conserving the view. So that people who don't want to see windmills on their bit of coast will try to claim to be conservationist.

The third group is opposed to modern life, and fearful of scientific and technological change. They are easily detected by their claim that primitive people are in tune with nature and never destroy their environment. How wrong they are! The greatest ecological disaster in Australian history was the destruction of the megafauna when Aborigines first arrived. Indeed it is impossible to understand ecological management in Australia unless you realise that we can't get back to the natural environment of 50,000 years ago. It is not the case that we can leave nature alone and it will return to a natural state. Instead without megafauna and Aboriginal burning we get fuel build up followed by ecologically disastrous fires.

A fourth group are anti-conservationists. They think that we should only adopt conservation policies when there is no risk to humans, and damn the environment. In particular they favour continuing to burn coal and build dams rather than moving to nuclear power. The environmental impact of blocking the natural flow of rivers and of pumping CO2 into the air is horrific. The environmental affect of nuclear power stations is to create a really effective nature reserve around them. An accident has no negative impact on wildlife. Chernobyl has allowed the native flora and fauna of Ukraine to return. Not that we'd embark on nuclear power if we expected accidents. There is every reason to believe that Australia at least would run such stations very well. And we can quite easily site them far from the madding crowd. And we have just as much uranium as coal. This is something we can do for the world.

The Greens are so heavily infiltrated with fake conservationists that I can't imagine them ever having genuinely environmentalist policies.

2005/03/12: In favour of sign language

It has been known for many years that the time to learn languages is when very young. Three or four is the best time to start, but five or six is ok. If you learn a second language early then your brain develops general structures which make it much easier to later learn a third or forth. If, like most Australians, you only know one language then the brain hardwires itself for that language and it becomes impossible to become fluent in other languages later.

Teaching a language is the natural thing to do at pre-school and in the early years of school. Children of that age are all wired up and ready to learn languages. Teaching them other things, like mathematics, is a waste of time. Children who learn non-language subjects at that age don't do any better, all else being equal, than those that don't. But for languages it is the best, and to some extent the last, time in which to do it. The failure of education departments to act on this knowledge over the last twenty years is verging on dereliction of duty.

There is a clear cut choice for a second language that can be taught everywhere: Sign language.

Sign Language

The language of the deaf is a real language. It isn't a variant of English. It has its own grammar and structure, so it fills the role of a second language for children. And adopting it has a lot of important advantages:

  1. It will greatly facilitate the integration of deaf people into the wider community if everyone learns their language.
  2. And indeed it will provide a fulfilling job to many deaf people as teachers of sign language, either directly to small children or else to other teachers.
  3. Any of us may become deaf. Those who don't learn sign language early are never proficient.
  4. More commonly we all have laryngitis and other diseases that cause us to lose our voices at times. Having sign language makes a valuable backup.
  5. There are lots of situations where sign language is much more convenient than speech: in the library; in a noisy venue; at the theatre or music performance; when filming or hunting wildlife.

Perhaps the most interesting situation where sign language might be useful is in negotiations involving multiple people on each side. I can just imagine the Chinese putting barriers between the seating positions of visiting Australian trade negotiators so that they can't sign to each other under the table during the negotiations.

Sign language is a natural part of the human language armoury. It was famously used between the plains Indians in North America. It is almost certain that sign language preceded spoken language in the human story. This avoids the chicken-egg problem that you don't need a complex vocal system unless you have a complex language and you can't use a complex language without a complex vocal system. The fact that the brain is wired to allow language information to flow through other routes and not just our mouth and ears is the reason that we can read and write.

Summary

Currently we take pre-school and early school children who are all ready to learn languages, but not much else, and we do little to develop them. Let's teach them sign language. The kids of that age will love it and it will have all sorts of later benefits for the children themselves and for society.

Moving wealth into the future through money

Saving is good, but what does it mean? If in the future we will need some grain, then it is wise to save some. If in the future we will need something perishable then maybe we can save something non-perishable that we can swap for the perishable item at that time. We treat money as such a non-perishable item. This works in a small way, for individuals, but not for a whole society.

Suppose I save some money in a suitcase under the bed. That reduces the amount of money in circulation (by a small amount), thus making all the money that is in circulation more valuable (deflation). When I later put the money back into circulation it acquires its value from all the other money in circulation by making that other money fractionally less valuable (inflation). In this way an individual or a group can move wealth into the future through money. Society as a whole can't move wealth into the future through money. This is slightly confused by the fact that an individual country might be able to do it in the context of all other countries. However since there is no global economic control, or global currency, a country can only do it by putting itself at the mercy of some other country, as countries holding US dollars do today.

There is also a problem when too many individuals try to move wealth into the future. In so far as they try to hold money they cause deflation. However governments can't allow that, so more money is put in circulation. The trouble is that this leaves the potential to cause inflation in the hands of consumers, and the government has more trouble taking money out of circulation when inflation starts. The other way people try to move wealth into the future is by buying assets. This leads to bubbles when there is too much money chasing too few assets of genuine long term value.

Money has three roles: as a mechanism for efficient exchange of goods, as a unit of value, and, as discussed above, as a way of moving moving wealth into the future. The first two are related and inseparable. The third doesn't work and gets in the way of the other two, because stored money is always threatening to flood onto markets causing inflation and bubbles.

More on this another day.

Climate change: a view from the right

We have to thank the Green Left for energetically bringing the issue of Climate Change to our attention. But now that we are starting to understand the problem we need to develop an Economic Rationalist solution. The views of the Green Left on how to solve the problem are not just wrong, they are dangerously wrong.

The message from the Green Left is that we have to sacrifice and suffer. If we suffer enough from higher energy prices from renewable sources, and from reduced energy consumption then that will solve the problem. Suffering is necessary and sufficient, they say. Does this sound familiar? Sacrifice and suffering is what religious leaders have been prescribing to appease the gods from the beginning of humanity. It taps into an instinct to sacrifice for the good of the community. We are all good at pretending to do it, while hoping that others do more. However it is completely irrelevant to solving Climate Change because it is not necessary, and because the sort of sacrifices being proposed, for example by Al Gore at the end of "An Inconvenient Truth", are nowhere near sufficient.

The first mistake is to see the solution in terms of specific regulations, penalties and subsidies. That always creates lots of busy work for government without making real progress on the issue. What we need to do is impose a cost on activities we want to reduce. I'll call that a tax. We want to give money for activities we want to encourage. I'll call that a negative tax. The Carbon Tax Base (CTB) will be the estimated cheapest marginal cost of removing 1 tonne of carbon from the air. Some fraction of the CTB will be applied to fossil fuels as they come out of the ground, and to imported fossil fuel (unless there is an intergovernmental agreement with the source country). The same fraction of the CTB will be paid, as a negative tax, to activities that permanently remove carbon from the air. Turning grassland into forest might be the cheapest way to do this, but it is a one-off and is not renewable. There may be a renewable solution here if the wood is regularly harvested and treated so that it won't rot. There will be in between cases where there is payment for CO2 taken out of the atmosphere (as wood in this case), and the money is repaid as positive carbon tax as the CO2 is returned (by rotting).

This proposal opens up every option to solve the problem. Energy costs are increased, so people will favour activities which use less. Fossil fuel is made less attractive as an energy source relative to alternatives. And finally people can put their minds to ways to remove CO2 from the atmosphere and get rewarded by that (and the continuing burners of fossil fuel will have an advantage in doing this, since they will have a more concentrated stream of CO2 to work with).

Initially the tax will bring in more than is paid out to those removing CO2. Indeed the aim will be to take 20 years to reach equality. During this period there will be a surplus, but the aim will be for the carbon tax to be revenue neutral. The excess will be returned to the people in the form of a negative poll tax (in other words equally to everyone). This will be quite close to an equitable way of helping people handle the increased costs. It would be silly to return the money in a way that gave more to those who use more energy since that would just subtract from the effect of the carbon tax.

There is basically just one parameter which needs to be adjusted in the scheme: the product of the CTB and a fraction chosen for policy reasons. This would be set by an independant body, following the very successful model of interest rates. The legislation would set Australia's aim for CO2 levels in the atmosphere. The independant body would aim to hit a net rate of emission/removal which would aim to hit the legislated target in about 50 years if all other countries were cooperating. It would work up to that cruising rate over an initial 20 year period.

Carbon Trading is another market based approach to greenhouse emissions. It is a left wing bureaucrats idea of how to do it. It targets the emissions, which need not be fossil fuel derived. It should target the fossil fuel extraction because that all ends up as CO2 eventually, and it is easy to police. Existing schemes don't seem to distinguish between renewable extraction of CO2 and one-off actions like reafforestation (which then needs to be policed to see that it isn't undone). Still this is an international system and the best way for Australia to use it would be to act as a single entity, with our verified CO2 extraction (paid for as negative tax) attracting carbon trading credits for Australia as a whole. We could then use these to encourage other useful activity world wide. And of course we should push for a more sensible international system, and make reciprocal agreements with other countries that are carbon-taxing fossil fuel mining.

The Green Left would say that the aim of combatting climate change is to return the world and its climate to its natural state. This is a terrible idea. With 6 billion mouths to feed, and counting, we need to manage the climate and keep it at an optimal level. Nature is just as capable as humanity of messing up the climate.

If you look at a graph of the world's temperature over the last 100,000 years or so you'll see this little straight bit in the top right. That's 8000 years of stable warm wet climate. Before that it jiggles around all over the place, and nearly always much colder and much drier than it is now. Very unstable, very cold and very dry is the worlds natural state since the age of the glaciers started half a million years ago. It is more important to avoid a return to those normal conditions than it is to avoid global warming. Of course global warming is much more urgent.

There is a lot of misleading comment around associating "warm" with "dry" climate change. Naturally the warmer the ocean is, and the higher the sea level, the more water evaporates, and the more rain that falls eventually. That's why the world's climate is either cold and dry during ice ages, or it is warm and wet during interglacials like the one we are enjoying. The reason the warm-dry combination gets mentioned is that climate change is not uniform. A British study based on simulations claims global warming will make 2/3 of the world wetter and 1/3 drier. However accurate that is, there are reasonable general arguments as well as simulations to suggest that global warming will make the southern half of Australia drier. Outside Australia the concerns about drier conditions seem to be only based on particular simulations and seem to be taken more seriously than they should.

Another popular misconception is that there was this CO2 in the atmosphere, just sitting there at a particular level, then we added more. In fact CO2 moves into and out of the atmosphere at quite a high rate. So, the fact that the level of CO2 has remained quite stable over long periods means that the rates of.CO2 entering and leaving are the same. But it means more than that. The world settled into a stable equilibrium of atmospheric CO2. If the amount of CO2 increases, say from a volcanic erruption, then the processes taking CO2 out of the atmosphere also increase, and similarly any decrease encouraged the processes that put CO2 back. We can imagine the state of the world as a balling rolling on a plane that isn't flat. It will roll down hill, following the course that water would take. Eventually it comes to rest in a depression. Whichever way it is pushed it wants to roll back to the lowest point of the depression.

Continuing our analogy, suppose we give the ball a push in a direction that we might call "higher CO2". Eventually we might push it over the lip of our local depression and the ball might start rolling again looking for a new depression: a new equilibrium point. However there is no guarantee that it will keep rolling in that direction. It might go around and end up in the other direction from the way it was pushed. In other words, a push in the direction of greater warming might tip us into an ice age, though perhaps not as fast as in "The Day After Tomorrow". I've been assuming that the push back force is well behaved like gravity. It might not be and it might force the ball back towards the low point, but then overshoot. In that way it might find a much lower lip that it can easily get over and then keep heading towards the other stable equilibrium that we know exists that puts the world into an Ice Age.

Suppose we set our CO2 target at 350ppm. Perhaps in 40 years the CO2 level will start to fall rapidly. If we've set up a flexible mechanism then that mechanism will react to support the CO2 level. When the carbon tax goes negative then business might go back to those abandoned gas fields and make money just by venting methane.

This plan doesn't involve government telling everyone what to do, it just readjusts economic incentives in the same way that interest rate adjustments do. This plan doesn't involve handing control back to mother nature, instead it takes a necessary step to control her. This plan doesn't involve any necessary sacrifice, it is designed to come in sufficiently slowly that it can leverage ongoing economic growth. These three things might annoy Bob Brown, but that is just a subsidiary benefit. The main point is that we need to solve Climate Change, and only rational economic policies will do it. If we don't do it then the Left will be pleased to take the reins, causing economic mayhem, and failing to address the problem.

2005/03/11: Workflow user interface

2005/03/11: Workflow user interface

My current obsession is workflow, and particularly a workflow-oriented user interface to everything.

Once upon a time computers were expensive and people were (relatively) cheap. So the idea was that people would attend to the computer and keep feeding it. The modern progress bar continues that idea: "here's something to look at while you wait for the computer to finish something". Window systems, and underlying multiprocessing, mean that computers can do more than one thing at one. Instead of looking at the progress bar we go to another window. Now we don't know when the activity is finished except by coming back to it. So we have to remember all the things that we are trying to juggle and keep going back and checking them for progress. So we need a workflow user interface, and what do people use: they use e-mail. That's something they keep looking at and maybe it comes with a notification system. But it is a really bad workflow user interface.

A real workflow user interface lets us know what activities need user input, or want it, or would be willing to receive it. My conception is that activities are organized in a tree and the nodes change colour: green means that this activity can't proceed without input from this user; yellow means the user might push things along, but does not have primary responsibility to do so; orange to red means that the user can only do things that won't affect other players much. For example if the activity is a chess game then the tree node for that activity is green if it is your move and orange if not (since you could resign) and red if the game is over.

Now we don't need a progress bar: the node for that activity will be reddish until it goes back to waiting for us to input. More on this another day.

Wirelessly networked PDAs threaten to become ubiquitous combined with mobile phones. These can hardly afford a multiwindow UI. Also it will be hard for the user to look around for stuff needing attention. Also interaction activities are likely to be the main applications. So for various reasons my workflow user interface is likely to be a good answer.

Oh to be Canada: Why do nuclear waste storage

It must be nice to be Canada. They don't have to go along with the United States' military adventures like Vietnam and Iraq, except when right and World opinion are behind them, as in Korea and Afghanistan. Yet they know that the US can never let anything bad happen to Canada. Australia would love to be in that position. Well we can. More details below, but first some introductory facts.

Australia's proximity to the largest Muslim nation makes us nervous. This is undoubtedly irrational, but the feeling is a potent force in Australian politics. The response is to show slavish friendship to the Americans. The electorates support for our involvement in Iraq is typical. The fact that the war is a disaster doesn't matter. In fact in a funny way it helps. Our message to America is that we support you, right or wrong. However our slavishness is going to start to wear thin with the electorate as the government enacts the provisions of the amusingly named "Free Trade Agreement", like the recent Copyright act that will make nearly every Australian a criminal.

As a practical matter it is not clear that all our attempts to ingratiate ourselves with the Americans will be effective. The American electors have still never heard of us, except for those who think we have something to do with "The Sound of Music". Their political system nearly always picks a state Governor with no foreign policy expertise for President. The Presidency does not adapt to shifting opinion in the way that a parliamentary government does. So it is by no means certain that America will help us when we need them, particularly if America has other problems distracting it at the time.

Fear of our neighbors might be irrational, but one thing that worries me is the nuclear waste that is scattered around the world, often in geologically and politically unstable areas. Personally I would be more comfortable if it was skillfully processed, then buried in our sparsely populated and geologically and politically stable land. One form of processing that would make sense would be to use it in a Thorium reactor. This produces CO2-free energy, and at the same time it reduces the radioactivity of the waste to a two hundred year problem instead of thousands of years. Australia has huge reserves of Thorium.

Indeed I think that we shouldn't be shipping out Uranium (or Thorium) and washing our hands of the waste problem. We should take it back, for everyone's greater safety.

There are lots of reasons why storing nuclear waste is a natural economic activity for our technologically advanced and Uranium exporting nation. But there is a huge additional side benefit. Suddenly we are like Canada. We become a nation that America, and other advanced nations, can not afford to let fall into the hands of the bad guys. We no longer have to follow America into every quagmire. We no longer have to submit to their latest schemes to protect their wonderful Intellectual Property from the depredations of Australian consumers.

This is a plan than can be sold to the Australian voters. It will make the World safer if we can get all that nuclear waste stored in deep and stable granite. And by making the Australian voters feel safer, we can turn Australia into a force for peace, as Canada has long been.

2005/03/10: HIV and male circumcision

Doctors are conscious of the importance of ethics, but many of them have no feel for the subject. A month or so ago The Age ran a story about a Professor Short who was recommending that male babies be circumcised for health: circumcised males are much less likely to get HIV from an infected partner. I wrote the following response, but never got around to sending it:

The discovery that uncircumcised males are more likely to get HIV led to an investigation of the role of the foreskin. It was found that it contained cells that were designed to interact with their environment. There can be no doubt that these cells are there because they are beneficial in some way. Even if you don't agree with that: there is no urgency to circumcise babies, because they won't commence sexual activity for many years. So why is Prof Short explicitly recommending that babies be circumcised? The whole point is to intentionally deprive those children of their right to give informed consent to the operation. This is disgraceful.

Of course religious Australians are entitled to circumcise their children for religious reasons. Secular Australians must be allowed to discuss secular ethics without religious Australians taking offence.

Integration of Muslim communities in the West

Women drive cultural conflict, as we particularly see with Muslim radicalization in Western countries. Indeed women are amazingly keen to risk male lives. I guess their genes know that there will never be a shortage of sperm, and the less aggressive males there are around the safer their children are. Anyway here's something I wrote about that last year, and about how to achieve cultural harmony in the West:

Muslim culture is part of the normal spectrum of human cultures. It is not long ago that Western culture severely limited the rights and opportunities of women. That world is perfectly described by Jane Austen, one of our greatest writers. Towards the end of "Pride and Prejudice", Mrs Bennett says of her naughty but lucky daughter and her new no-good son-in-law: "We must have them to dinner". Mr Bennett is heard to say "They will never enter this house". Somehow we are not surprised to see the disreputable pair arriving for dinner. Indeed in nearly all the relationships portrayed in the book, the women strive and succeed in getting their way with their men. The exception is Jane and Mr Bingham, and that relationship seems completely implausible: who can believe a man really falling for someone who makes no attempt to stand up for herself in the relationship. We believe attraction, and lust, but we don't believe he can fall in love.

How much influence do women have on male behaviour? We know from the statistics that delinquent boys turn moderately responsible when they get a steady girlfriend. When it was suggested to Winston Churchill that women would rule the world in 2050, he replied "Still?". However a nearly universal aspect of human behaviour is that women defer to men in public. If a woman shows dominance over her husband in public, it reduces his status, and that is unlikely to be in the interests of her family. So Western culture is familiar with the idea of the woman going along with her husband in public, then telling him off in private. It is one of those incongruities that comedians love to exploit.

If women are so powerful within relationships, then why do they let themselves get into positions of limited rights, as in Jane Austen's day, and with Muslim women today. We really need to understand this in the modern Western world where young Muslim women, raised in the West, are taking to scarves and veils that their mothers had escaped. The answer is that it is a mistake to see men and women as separate groups that are in conflict for power and status. Rather it is groups of men partnered with women who are competing with other such groups of men and women together. We can hardly imagine the importance of this competition in our wealthy society, but historically most societies have lived close to the edge and power and status greatly increased the chances of survival and reproduction.

When we look at it that way, we can see that women will not necessarily wish to have the cultural dial set to a point where women have independence and public power and status based on merit. Different settings favour different groups. How much influence do women have in setting this dial? My opinion, and the argument of this document, is that women are actually by far the main influence in setting the cultural dial. When there was resistance to votes for women, this resistance included women. When resistance from women stopped then resistance from men faded away. Similarly we see, and are shocked to see, in the modern world that women are often involved in supporting activities that attack the rights of women: genital mutilation, honour killings, wife killings. Terrorism would not be possible without at least passive female support. Men would not do this if it meant coming home to the disapproval of mothers, sisters and wives.

If we can find a way to get into a dialog with Muslim women in Australia, then there are two things I would say to them in the form of a deal, discussed below. Others may have other ideas. Certainly we need to keep the conversation reasonably simple. One way to organize it would be to invite women to meetings which would elect representatives to meet with the governments representatives (female) and then report back. A way of compensating the women for their time would be to give them a voucher at the first meeting that would be redeemable for $100 at the 2nd.

The first thing the government needs to say to Muslim women is this: In the important business and government organizations in Australia, women have equal rights. If Muslim sons and husbands go to work in these important organizations, and we want them to, then they'll always be working with women and sometimes they will have women bosses, and women subordinates. This equality of women at work is an absolutely non-negotiable part of Australian life. We would eventually like Muslim women to actually take part when they are comfortable doing so. More immediately, and the first part of this proposed deal, we want Muslim women at home to encourage their men to get a good education and join these important organizations and accept the environment of equality there.

The other half of the proposed deal concerns politeness from the rest of Australian society to the Muslim people. I try to explain to my 3 year old grandson the difference between "bad" and "rude". You can be bad even when you are all by yourself. Rudeness is something you do, like saying a rude word, that is upsetting to other people. We vary what we say and do depending on who is around. To allow and encourage Muslim Australians to participate more in wider society we all need to avoid behaviour which Muslim people will perceive as rude. There are limited situations where the government can directly change this, such as broadcast TV and what is displayed on the public street. The main part of this offer from the government to Muslim people is to advertise to make people aware of the need for more modest behaviour in public and modest attire, particularly at work. The place for normal Australian vulgarity is at home, and in places where Muslim people will know not to go, such as pubs.

So that is the proposed offer. We want Muslim Australians to join in the major activities of Australian life, accepting the non-negotiable fact of female equality in those environments. In exchange the government will do all it can, without infringing civil liberties, to avoid activities which are rudely insensitive to Muslim people.

This is a small step. Others are needed. I support the call to have only government primary schools -- compulsory, very well resourced, and with thorough mixing, using bussing if necessary. Also, the more ways the government can find to give resources directly to women, such as the baby bonus, the better. Maybe somebody will do a movie of "Pride and Prejudice" set in the Muslim community in Australia, to remind us how close we are.

2005/03/08: Lack of trust in official health advice

In the Age (theage.com.au) a nutritionist gets stuck into people like me who are trying a gluten free diet without having probes inserted and biopsies taken. It claims that only people with full celiac disease should avoid gluten.

Why don't we trust these official pronouncements on diet? We just suspect that they are working for segments of the food industry. Gluten is associated with other health problems, particularly autism.

There are plenty of other cases. There is a compelling case that the western diet is magnesium deficient. And there is the amazing suppression of the A1/A2 milk story. Here is an extract from the NZ Food Safety Authority's study:

The best study was the most recent one which had a better design with blinded assessments where possible and a random allocation to diet or no diet. The majority of the measurements showed significant improvements on the diet (casein-free, gluten-free).

4.4 Summary and implications

The available evidence is suggestive of a role of reducing the casein and gluten in the diets of people with autism to improve the autistic behaviours and overall functioning of the individual. Further research is needed. The evidence is not strong enough for clear dietary recommendations to be made for people with autism and schizophrenia.

You'd think that governments would spring into action to evaluate the health risks of milk and whether it is particularly A1 milk that causes problems. But no: silence has descended over the whole matter and A2corporation has been beaten up in the courts to stop "false claims".

It is hard to think what could be done to restore my faith in nutritionists. Robust public debate without law suits. Funding of serious trials. Extricating nutritionists from the grip of the food industry. These would certainly help.

P.S.2003/03/09: Another example of failure to act where there was good cause for concern was the issue of honey with toxins from Patterson's Curse (aka Salvation Jane). The issue of the need for more sun exposure (with lack of sun exposure strongly implicated in various problems including osteoporosis and cancer) is another where people have to find out for themselves: official sources are silent. For most health issues you have to find out for yourself and weigh the evidence yourself without trustworthy guidance. It is then really stupid for the people who should be providing sound guidance to criticise us if we get it wrong by being overcautious.

Iraq and oil

The fact that the Iraq war is about oil is not news to many people. Nearly everyone, supporter and opponent, has known this from the beginning. All the other explanations have been provided with a metaphorical wink and a nudge. The practical economic purpose of the war has been the reason why there has been public support, even as casualties have mounted. The war is more about being well placed to protect Saudi oil, without having troops on holy Arabian soil, than it is about Iraqi oil.

So why did Howard (delicately) and Nelson (indelicately) have to say it? The answer lies in the Liberal party's parlous electoral position. Maybe 90% of the electorate already knew, but the government feels it has to reach that other 10% and tell them that the whole thing has some practical purpose. Of course their hasty retreat shows that they are well aware of their dubious ethical position, and that is what this post is about.

My grump for the day is with the journalists. When Nelson said "oil security", the question that needed to be asked was: "Do you mean helping the legitimate owners of the oil secure it against 3rd parties, or are you talking about securing it for our use against the legitimate owners?" Of course we all know that the latter is the case, but he would have been forced to respond with the former. But at least once he'd responded we can ask him who the legitimate owners of Saudi oil are: the princes who put the money in Swiss bank accounts, or the people who currently get the crumbs.

Which brings me to the biggest mistake of the Iraq war. The effect of preventing the Baath party and other opponents of the Americans from standing in the election was that the election had no legitimacy, particularly in the eyes of those opponents. If the Baath party, and even Saddam himself and al Qaeda, had been allowed to stand then they would have been roundly trounced, and the government would have had legitimacy, and everything would have worked out much better. As it is the insurgents can reasonably choose to ignore the election, assert that the government has no legitimacy to request American military presence in the country, assert that the current government are Quislings, and claim the normal human right to resist foreign occupation. And isn't it incredible that the Americans, whose country was founded on that right, completely fail to perceive its possible applicability here.
