Hemp is not the answer. It takes energy to harvest (like corn, switchgrass and all other crops). Now, you run into the azeotrope problem that I keep preaching about and people keep ignoring. It's it a fundamental chemical property of water/ethanol mixtures being turned into fuel.
It won't work. Ethanol simply isn't the answer and will never be unless you're cracking it for the hydrogen and even then, there are more efficient ways of obtaining hydrogen.

Bingo. The energy costs to manufacture it would offset the benefits for now anyways.
