I'm surprised no one has mentioned converting a car to run on used vegetable oil (usually happily donated by a greasy restaurant). Just google it on the internet - unfortunately it looks like a lot of labor, but for a very inexpensive result. Actually another risk for people like me is that the smell would constantly make me crave french fries.
