Dog Waste Converted into Power?

SAN FRANCISCO San Francisco officials are looking into using dog poop as a source of renewable energy.

Norcal Waste, the garbage hauling company that collects the city's trash, plans to begin a pilot program. It will put containers in some dog parks, allowing owners to deposit their pet's waste in biodegradable bags. The bags then will be dropped into a device called a methane digester where bacteria can feed on the feces for weeks, converting it into methane gas.

The methane could be piped to a gas stove, heater, turbine or anything else powered by natural gas. It also could be used as vehicle fuel and to generate electricity.
