Waste water plus bugs make hydrogen
"You could go to a farm, where there's lot of cellulose or ... agricultural cellulosic residues, take that and make hydrogen there."

State College, Pennsylvania, USA - Bacteria that feed on vinegar and waste water, zapped with a shot of electricity, could produce a clean hydrogen fuel to power vehicles that now run on petrol, researchers report.
These so-called microbial fuel cells can turn almost any biodegradable organic material into zero-emission hydrogen gas fuel, says Professor Bruce Logan of Penn State University.
