Default Fuel Cell That Uses Bacteria To Generate Electricity

Fuel Cell That Uses Bacteria To Generate Electricity
ScienceDaily (Jan. 7, 2008) — Researchers at the Biodesign Institute are using the tiniest organisms on the planet -- bacteria -- as a viable option to make electricity. In a new study featured in the journal Biotechnology and Bioengineering, lead author Andrew Kato Marcus and colleagues Cesar Torres and Bruce Rittmann have gained critical insights that may lead to commercialization of a promising microbial fuel cell (MFC) technology.

"We can use any kind of waste, such as sewage or pig manure, and the microbial fuel cell will generate electrical energy," said Marcus, a Civil and Environmental Engineering graduate student and a member of the institute's Center for Environmental Biotechnology. Unlike conventional fuel cells that rely on hydrogen gas as a fuel source, the microbial fuel cell can handle a variety of water-based organic fuels.

"There is a lot of biomass out there that we look at simply as energy stored in the wrong place," said Bruce Rittmann, director of the center. "We can take this waste, keeping it in its normal liquid form, but allowing the bacteria to convert the energy value to our society's most useful form, electricity. They get food while we get electricity."

Default New Microbe Strain Makes More Electricity, Faster

New Microbe Strain Makes More Electricity, Faster
ScienceDaily (Aug. 3, 2009) — In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, Derek Lovley and colleagues at the University of Massachusetts Amherst supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power. It also works with a thinner biofilm than earlier strains, cutting the time to reach electricity-producing concentrations on the electrode.

New Microbe Strain Makes More Electricity, Faster
excerpt from above:
Quote:
“In very short order we increased the power output by eight-fold, as a conservative estimate,” says Lovley. “With this, we’ve broken through the plateau in power production that’s been holding us back in recent years.” Now, planning can move forward to design microbial fuel cells that convert waste water and renewable biomass to electricity, treat a single home’s waste while producing localized power (especially attractive in developing countries), power mobile electronics, vehicles and implanted medical devices, and drive bioremediation of contaminated environments.

We need to cross our fingers and hope an oil company doesn't buy the patents to these.
