Poop fuels hydrogen cars

Publication: msnbc.com   Date: August 11, 2011   View Article

An experimental fuel cell at a wastewater treatment plant in California is turning poop flushed down the drain into hydrogen fuel for cars.

The novel fuel cell converts biogas — methane — produced in digesters at the plant into heat, electricity and hydrogen. The heat is fed back to the digesters, the electricity powers the plant, and the hydrogen is fuel for cars.
