It compares corn-based ethanol with soy-based biodiesel, commenting on energy gain and emission reductions.

Interesting article- I'm glad to know that all the biofuel hype has SOME basis in fact. I didn't realise that using soy as a biofuel has carbonload benefits as well. While there is such investment in maintaining the supremacy of the gasoline engine for cars, I guess corn ethanol is what everyone will push; I'm aware that many more acres of the MS delta will be under corn (for ethanol) rather than cotton. Given the chemicals used for cotton production, corn might actually come out ahead ecologically. I wonder if anyone is investigating crops like cassava and manioc- it seems that the leaf matter could be used for fuel, and the tubers for food. Since the leaves are toxic to many insects and small critters, there's much less need for pesticides, and now that there are commercial scale methods for processing the tubers, it could at least be used for animal feed, if not for human consumption. Just a thought, anyway
