National Geographic reports: "Crude oil and gasoline prices are near an all-time high. But don't despair. One scientist has found an alternative source of energy: pig manure."
It seems that we can make alternative fuels from corn (Ethanol), vegetable oil (Biodiesel), and now pig manure. It is absolutely amazing what they're making fuels out of these day. One day we will be able to run our cars on just s (wait, that has already been invented too).
