Since it takes about a half gallon of gasoline to make a gallon of ethanol with corn, why are they not allowing hemp to be grown in this country? I'm not talking marijuana to smoke, but hemp, which is a tall plant, with lots of cellulose that makes ethanol a lot better and cheaper than corn ethanol. We could also get our rope material, fabric material out of it before loading it in the ethanol plants. In iowa, here, we could grow hemp on hills and valleys that are no good for corn or beans. It would bring in extra money, and could be vital to the ethanol plant, instead of corn.
