Bath Bus Company is harnessing the power of poo. Its new Bio Bus fleet runs on waste gases from the biomethane decay of human feces and food scraps, and is now carrying passengers from Bristol to Bath, U.K.

Using what amounts to the yearly waste of five people, the bus can travel 186 miles on a tank of poo. It's a new spin on the idea of energy independence... and adds a strange new step to the cycle of buying local.

The buses use a diesel-like engine to combine the methane gases with propane, but the resulting fuel has 30 percent fewer carbon emissions than pure diesel. If the program is successful, perhaps a brown energy economy will become part of the green movement.
