Not that's what I'm talking about:
http://www.wired.com/wiredscience/2011/09/bacteria-water-hydrogen-fuelUsing the natural process of osmosis across a membrane between salt water and fresh water, you can create an ion deficit/ surplus on two sides of an Anode/Cathode pair, of course creating the possibility for electrical current. But the amount is very small. Put 5 such "batteries" together in serial and you do better.
But add a particular type of bacteria, give it food like acetate or better, animal/human waste, and you get a radically larger amount of current. More importantly, the byproduct of the bacteria poop is hydrogen.
Love it. Where can I buy stock?
