Eugene, you may don't see it in a big Chicago - maybe too busy to see it, but if you take a drive around country you can see a lot of people began to use solar and wind energy. and if we had cars offered to us which use green oils don't you think we would of purchased them instead.. let's say bmw or dodge offer us something like this? which is not hard to do for them, they can switch overnight, but they don't because we still buying their cars as it is (I have 740I myself, I love bmw), we still buying gas that tripled in price because we "have to" and a lot of people like Mihail and Vitaliy still wants to vote for the candidate whom paid off by oil lobbies...
