Here's a note that should thrill all environmentalists.The Integral Fast Reactor,or IFR,(check Wikipedia)could generate sufficient electricity to electrolyze(split)ordinary water into hydrogen and oxygen.Current internal combustion engines can burn hydrogen with little modification to use hydrogen in place of petroleum with a slight loss in efficiency,a small price to pay to avoid the projected consequences of global warming.The emissions,water.Thats it.No CO2 emissions to generate the electricity,so you could continue with expanded IFR use without horrible environmental consequences.A win-win
