More on biodiesel

I did a little follow-up work on my biodiesel post from yesterday. The authors of the study, which unfortunately seems to be getting huge publicity, seem pretty clearly to be dead-set against biodiesel, regardless of the facts. Their "analysis" assumed high-energy inputs in both the growing of soybeans and the production of biodiesel from them, and they even made a rather obvious arithmetic error which (surprise!) supported their bias. I have adapted and commented on a couple of the tables from their article here. (The full article is not legally available publicly; I got access to it through my university connections. But I think my analysis easily falls under "fair use.")
