I was waiting for that. Not being a scientist, even I know that producing enough of the material just to be burned up is not going to see wide spread use. All these people seem to forget the amount of energy it takes to make energy. What's going to power the mines?
I see solar, wind and water movement as the best 3 approaches, even if they are only used to refine petroleum.
But, they certainly can shift some of the use of petro fuels away from electrical generation and the like. We can't build more dams because of the rivers and water life? I'll bet we could if we studied the issue a bit more. Why do we have to stop up the whole damn river? Can't we "waste" a little water?
