Coal bad Glass good
I urge everyone to read Gregor Macdonald on “Coal and Treasuries” at http://www.theoildrum.com/node/6175. CO2 policy is about exactly one thing: leaving coal in the ground. Everything else is fluff. Nuclear is the only thing that can replace it. Australians need to understand this.
And here is a potential game changer, spray on very thin glass: Spray on Liquid Glass to Make Things Easier to clean and antimicrobial for Years and Can Increase Crop Yields. Need to be sure that fragments of it aren't more of a health hazard than the normal SiO2 dust we all live with. Just the seed protection alone seems likely to help us get through the peak oil food crisis.
