The amazing microbial fuel cell: turns poo into power

Now if they can just put this in a car....  Imagine, no more pulling over 10 times on a long trip so the kids can go potty.

Microbial Fuel Cell

Researchers at Penn State, working in cooperation with a scientist from Ion Power, Inc., have developed a microbial fuel cell that can turn wastewater and bacteria into hydrogen. According to Penn State, the new process can get up to four times as much hydrogen straight out of the biomass than what can typically be generated by fermentation alone. But Bruce Logan, the co-inventor of the process (seen at right), doesn’t think he smells a solution to the world’s energy problems, saying that there’s just not enough “waste biomass to sustain a global hydrogen economy.
