Most of us just flush it down the toilet, but a group of four girls in Africa turned urine into electricity. 14-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola created the project for the recent Maker Faire Africa in Lagos, Nigeria.
So how’s it work? Basically they use a few different chemical processes to extract and purify the hydrogen from the urine and then use the hydrogen to fuel a standard generator.
One liter of urine equals six hours of power. QED.
Here are some more pics of the project from the Maker Faire Africa blog.
