Pee-power toilet to light up disaster zones
After a few drinks, the call of nature inevitably beckons. But scientists from the University of the West of England believe urine isn’t just the result of one-too-many, but also a potent energy source. This prototype pee-power toilet is harvesting human urine to generate electricity. Led by Professor Ioannis Ieropoulos, the scientists are working with aid agency Oxfam to install cubicles like this in refugee camps.
