I really wonder why farmers don't run their equipment on biodiesel or bioethanol. (Actually, the answer is bloody obvious. Admittedly somewhat off-topic, too.

  AFAIK there's been some success in Germany with being able to combine a big enough crop devoted to biodisel along side a meaningfully size crop for food - but oil, especially subsidized oil, is really cheap energy. But there was recently a big scare connected to farmers taking subsidies to produce biodisel - and biodiisel production out-competing food production and/or leading to hike in food prices... so yeah. If you have X square meters in which to grow food, you can't readily use some large percentage of that for "growing" biodiesel, without cutting into your food grow area. I'm sure there are certain biomass that will work as both, but it's not trivial to "just use biodisel".
