Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin & Bello Eniola: Four Nigerian teenagers have come up with a way to use 1 litre of urine to power a small generator that provides 6 hours of electricity. The urine is passed through an electrolytic cell, which separates out the hydrogen which is then passed through a water filter for purification and then into a gas cylinder. The hydrogen is pushed into a power generator to complete the process. Though in need of much refinement & technological advancement it has been hailed as bold step in figuring out how to use bodily waste as a bio fuel.
