Urine could charge mobile phones
A team of experts working at the Bristol Robotics Laboratory have been able to charge a Samsung phone by putting urine through a cascade of microbial fuel cells. They have generated enough electricity to send text messages, browse the internet and make a brief phone call.
The scientists now plan to develop the technology to be able to fully charge the handheld device.
The project has been funded by the Engineering and Physical Sciences Research Council, the Gates Foundation and the Technology Strategy Board. The 'Waste to Real Energy: the first MFC powered mobile phone' article has been published in the journal Physical Chemistry Chemical Physics.

-- In 2006, Cellular News reported that physicists in Singapore had developed a battery that could be powered by human urine for for those "emergency" phone calls when your conventional battery has died.
-- The first urine-powered paper battery was created in Singapore. The credit-card sized unit could be a useful power source for cheap healthcare test kits for diseases like diabetes, and could even be used in emergency situations to power a cellphone.
