If You Can Pee, You Can Make a Phone Call

If asked what would be a great power source for mobile phones, it’s a fair bet that most people wouldn't make urine their first choice. But that's exactly what a group of scientists at Bristol Robotics Laboratory in the UK have done. As part of a project to find new ways to provide electricity for small devices in emergency situations and developing countries they have created a new fuel cell system powered by pee.

 The key to this rather unorthodox way of powering a phone is a microbial fuel cell (MFC) that converts organic matter directly into electricity. Inside the MFC, there are a mixture of ordinary anaerobic microorganisms that release electrons as they feed – in this case, on the urine. (more)

Thus giving a whole new meaning to streaming media. (rimshot!) Gee whiz.
