Urine-powered generator unveiled at international exhibition

Four African 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 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.

And as for delivering the fuel itself? Well, we'll leave that up to the consumer.
