UK scientists are claiming a world first in developing a way to charge mobile phones using human urine. The Bristol-based boffins 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.
