Out: Solar power. In: Poo power?

Electricity could be generated from microbes in sewage, according to U.S. scientists.

The team have created a ‘battery’ driven by microbes that produce electricity as they digest organic material.

They claim the microbial battery could offset some of the electricity now use to treat waste water.

That use currently accounts for about three per cent of the total electrical load in developed nations.

The system was developed by Stanford University in California and their results published in the Proceedings of the National Academy of Sciences.
