Bacteria is being used by OSU to enable self-sustaining treatment plants that feed on sewage to generate electricity.
Here's what EETimes says about coverting sewage to electricity: A nanotech coating is claimed to boost the efficiency of microbial fuel cells by 20-times, taking the technology one step closer to commercialization. Microbial fuel cells use bacteria to break down sewage while at the same time generating electricity, combining a renewable energy source with a pressing worldwide need to provide clean water to municipalities. When the technology is perfected, researchers hope that sewage processing plants can become self-sufficient—generating enough electricity from sewage to power the water purifying machinery...
