Bio-fuels *are* a great idea.

Until you realize *how much* gasoline & diesel this country uses
(then add 3x more to that for the rest of the world), and the fact
that stuff like corn ethanol needs lots of (*petrolem* based)
fertilizer.

(However, sugar cane ethanol in Brazil is a *great* idea, because of
cane's higher sugar density, Brazil's proximity to the equator and
lower population).
