Researchers create super-efficient microbial fuel cell, dream of selling excess electricity

Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and altered bacteria, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons - rather than the hydrogen or methane that other methods rely upon - are produced and run from an anode to a cathode within the device to create an electric current.
