Waste-burning Fuel Cell Could Power a Hydrogen Future

Microbial fuel cells may well be the next black (or at least brown) gold. But to tap those anaerobic reserves, we'll need a power station that can run on carbon-rich gas. Something like the DFC-3000 fuel cell—it turns biogas into power 2200 for homes and their hydrogen cars. » 3/26/12 11:35am 3/26/12 11:35am
