Jatropha Being Developed as a New Biodiesel Source

Shaun, you have a good point, though I don't actually feel negative about the article on jatropha, which sounds like a nice, "juicy" plant.

Insofar as hybrid cars (and trains, for that matter), I think compressed air is probably the most efficient method of storing energy (and I am apparently correct, according to the recent cover story in Scientific American, which proposes compressed air as a means of storing energy from solar).

Of course, I don't mean to imply that any one method should dominate the energy sector -- that would be the same idiotic mistake that our oil/coal/nuclear based economy was based on originally, and why we're in a polluted, violent, screwed up world. Certainly batteries and ultra-capacitors have already shown their worth, and will continue to do so.
