I say we build an engine that can run on beer.

Seriously though, I heard on Paul Harvey years ago that there is a lot of corn waste - cosmetically imperfect ears, cobs, etc. - in the US that could be used for fuel but nobody wants to touch it so it just rots back into the ground. It's too bad because not only could consumers benefit, but so could the farmers, especially during years when their marketable crop suffers.

But I guess that just makes too much sense.

I believe there is money to be made in any kind of fuel and that the oil companies would Still Make Money even if they got away from Oil. But I'm just an unfrozen caveman, what do I know?
