No, corn is not gonna do it. I personally love the idea of E85 being widely available (105 octane, just hafta use a lil’ more of it) but unfortunately, corn does not have enough sugar in it to make it economically viable (costs more to produce the alcohol than it sells for - that’s why it’s subsidized). Sugarcane is the only crop that will generate a payback. Look at Brazil. They are 60% self-sufficient on E85 made from sugarcane. Unfortunately we don’t have the best climate to grow sugarcane (except Hawaii).
