Re:How bout ethanol? (Score 1)

Why haven't ethanol powered automobiles showed themselves? Corn products seem like a great way to help improve the economy by helping out the farmers, providing new jobs, and lowering the dependence on petrol?

1. Because it takes more energy to plant the corn, harvest the corn, and turn it into ethanol than what you get back when you burn it. If cars ran on ethanol, we'd actually be burning
2. more carbonaceous fuels, not less.
