Four African Teenagers Create Power From Pee
Wednesday, November 14, 2012
Over the last two days, Lagos, Nigeria has hosted Maker Faire Africa, the Maker movement’s bastion on that continent. One of the most impressive and surprising devices displayed there is a device that uses a material we all have ready access to in order to power an engine. That’s right: four girls, aged 13 and 14, have created a prototype generator that runs on urine.
For one liter of urine (about half what a person produces in a day), the generator will six hours of electricity. The process works by separating the hydrogen out of the urine, and then using it to power the generator.
