I guess my take is simpler than a lot of the arguments floating around here. if the current price tag is not acceptable, what price would be? Or, are we really saying that we'd rather spend the money elsewhere? Biodiesel has some advantages, and many disadvantages. To me, I could see this being a part of a energy mix, but it doesn't seem like it is worth the money we are spending on it today, given that we could get better renewable energy/dollar in several other ways. If anything must be spent here, it seems we need some research to figure out how to do this better.
