Wee-powered phones

Claiming a world-first, scientists from Bristol Robotics Laboratory, have used urine to produce electricity to charge a mobile phone. The urine is passed through microbial fuel cells and, so far, enough power has been generated to enable the phone to make a brief phone call, send text messages and browse the internet.

The team developed a microbial fuel cell to convert energy. Live microorganisms inside the fuel cell process the urine to produce electricity.

They are now working on scaling up the electricity output from Microbial Fuel Cells. They believe that the technology has the potential to be installed into domestic bathrooms, producing electricity to power showers or lighting as well as mobile phones.
