Brazil is magic, we can't do what they have done. The highly profitable ethanol plants only run on government dollars. Why invest in alternative fuels now when we can keep giving Oil barons our money and trust them to wean us off of their product. The status quo cannot be improved in my lifetime, I'll fight progress away from petroleum till I die. Make my kids drink MTBE, anything but natural safe renewable bio-fuel.Subsidized, corn derived ethanol doesn't make much sense, IMHO. I want energy independence. I have no problem with fuel from biomass, waste, switchgrass, etc.
Kudzu is the answer, it is immortal and unstoppable, it provides protein for animals and incredible biomass. It will grow anywhere it is not wanted.
