Besides, if it doesn't work out, fusion power is only 20 years away, and can perpetual motion be much later than that?
Buck, if we found a way to produce all the energy we needed without any pollution, those who profit from fossil fuel would also fight that. They simply don't care what happens as long as they don't have to pay the bill when it comes due. The only economic law that you can really count on to work is "Money doesn't talk, it swears."
