Sewage plant can produce hydrogen with purple bacteria

Someday you may fill up your hydrogen fuel cell car at the wastewater treatment center. City buses, some of which already run on fuel cells, could run on this stuff. This research discovered that purple bacteria, with a little energy, were amazingly effective at converting the carbon in sewage into biofuel.

Purple phototrophic bacteria -- which can store energy from light -- when supplied with an electric current can recover near to 100 percent of carbon from any type of organic waste, while generating hydrogen gas for use as fuel.
