Researchers at the University of the West of England have developed a urinal prototype that converts urine into electricity. Human urine has been used for a variety of things over the centuries, from distilling phosphorous to producing gunpowder.
Of course, for a urinal prototype to work, it requires a constant supply of pee -- which shouldn't be a problem given that this urinal is thoughtfully located right outside the student union bar at the university. The structure is fitted with a clear plastic screen through which people can observe the microbial fuel cell process that converts the electricity into electrical power.
As the global community is forced to become increasingly creative in its quest to generate power sustainably, this urinal prototype project is hugely encouraging. After all, the world may run short of oil or wood but where there are people, there will always be pee.
