text: is there a cheap, realistic & practical method to extract hydrogen from water? with the crude oil soaring and heading to $ 100 +, is all the take about altnative fuel and hydrogen economy is just a dream? the closest we could come to doing it economically would be electrolysis using off peak power from nuclear power plants.  in the future we might be able to use more efficient thermo-chemical processes using the higher temperatures that future reactors will be able to provide.
