British Researchers Test 'Pee-Power' Urinal

Researchers at the University of the West of England and the humanitarian organization Oxfam are testing on the streets of Bristol a new urinal intended for refugee camps. The urinal uses urine to power microbial fuel cell stacks, which in turn generate electricity. To ensure the prototype sees plenty of traffic, the urinal is "conveniently situated near the Student Union Bar," the university said in a press release.
