‘Living battery’ generates electricity from sewage and wastewater

A new type of living battery has been created that generates electricity from dissolved organic matter such as that found in wastewater flushed down the toilet or washed off farms and out to sea.

The system is as efficient as the highest performing solar cells and, in theory, could generate as much energy as is needed to treat wastewater with current technology, according to researchers working on the so-called microbial battery at Stanford University in California.
