I think we found an alternate solution to our Gas problem. Our country has found a way to make ethanol or fuel made out of corn. This does not come without drawbacks though. Because we are converting corn to gas, corn as well as certain food prices have close to tripled! Godd luck in trying to use this without damaging your wallet.
I have heard of an experiment a group of college kids did where they rigged a car to use cow manure for fuel.
I wonder if there are any other solutions that would not punish our wallets....
