I can't help but think that with Biodiesel, whether soybean oil, peanut oil, mustard seed oil, etc... Or ethanol from corn, milo, wheat, etc. We sure don't have enough WVO around in one small city to fuel anything more than one block of households. Do we have enough farm-land and resources to fuel the US/Canada on a plant based fuel? We burn so much gas that it seems that every last acre of the US would be used to create enough fuel. Not to mention that most of the northern states that grow corn for ethanol can only grow during the summer because of the single crop per year season due to the climate. It seems like we would have a price difference during the winter every year. What do you guys think about this? I'm just curious how feasible do you think this could be?
