  • Scientists turn pee into power in Uganda

    Labs and researchers have discovered that urine can be used as a renewable energy resource by using microbial fuel cells to generate electricity. It’s a cheap, abundant resource and the nutrients in the urine can also be used to fertilize gardens and save on water. One lab has produced 1,760 fuel cells so far, some of which have been placed in local schools.
