Ok, so I was slightly innacurate with the ethanol. It is possible for it to be +EV in some situations in fact, in many situations. I've even posted links about that in the past where conola is 0.8 input/output ratio as shown in this link:

But many are -EV or simply not scalable. Even in situations where it is +EV, the difference isn't anything to get excited about in cost or ROI energy value. I have said in the past that biodiesel will be helpful especially with algae but corn simply isn't the answer.
That original post was long and I spend too much time here as is and was pissed off when I made this post..... sorry about the error. I'm trying to balance time and failing misersably.
Guh... short on time.... Gots to go.
