(2014) Four African (Yoruba) girls have created a generator that produces electricity for six hours using a single liter of urine as fuel. The generator was unveiled at last week’s Maker Faire in Lagos, Nigeria, by the four teens Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all age 14, and Bello Eniola, 15.So how exactly does the urine-powered generator work?*.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 gascylinder.*.The gas cylinder pusheshydrogen 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.And as for delivering the fuel itself? Well, we’ll leave that up to the consumer.The Maker Faire is a popular event across the African continent, drawing thousand's of participants who travel to Lagos to show their inventions and other practical creations.
