What were you doing when you were 14? I bet you weren’t collaborating with friends on a generator that works by converting urine to hydrogen. Well, that’s exactly what the 14-year-old quartet of Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin and Bello Eniola did for Maker Faire Africa. It’s as complicated as it sounds, but necessity drives invention and these girls responded to the needs of their surroundings. As is explained on the Maker Faire website, “The system works like this: Urine is put into an electrolytic cell, which separates out the hydrogen. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas. This purified hydrogen gas is pushed into the generator.” It’s not your average science project, and though the girls’ current prototype converts 1 Liter of urine into 6 hours of electricity, it is admittedly a project that is still in its rudimentary stage, but we’re highly impressed nonetheless.
