#Nanotech to Covert Sewage into Electricity

The world is quickly running out of fresh water, but these researchers claim to be able to convert sewage into clean water with microbial fuel cells that harvest enough energy to run the plant. Look for self-sustaining sewage plants by the end of the decade. R.C.J.


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...
