Since I don't know much about those batteries that power the hybrids, I did a little googling, and found some interesting stuff.

"Pragmentalists vs Environmentalists (Part 1): Prius: Green or Greenwash?"
http://www.khoslaventures.com/presentations/Hybrids.pdf

This article equates a Prius with a Gucci handbag: they may be popular but people are always gullible to good advertising. This article also mentions the 'flex-fuel' cars: "It (Prius) and its cohort hybrids are unlikely to make 50% penetration of the new car sales worldwide (or US) anytime soon. Flex-fuel cars went from under 5% of new car sales in Brazil to over 75% in less than three years because they don't cost any more than a regular car. They are projected to be 50% of GM, Ford, and Chrysler’s new car sales by 2012 in the US."

I am not familiar with flex-fuel cars, but I hate buying a new car so much I tend to wait until mine are almost composting back into the soil before I look for a new one.

Are flex-fuel cars available (or legal) in the U.S. at all?
