Nigerian girls create urine-powered generator
A team of Nigerian schoolgirls has impressed the crowds at Maker Faire Lagos with their urine-powered generator.
The girls, Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15), have built a generator that uses one litre of urine to deliver six hours of electricity.
The urine is placed into an electrolytic cell, which separates out the hydrogen. This 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.
