Urine-powered generator unveiled at international exhibition

11-12-2012 • http://news.yahoo.com

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.

And what powers the electrolytic cell?

This is just urine substituting for water. In a very electricity using process. To produce a substance that is hard to keep bottled up because it leaks through any seal.

And the other thing about urine versus water it stinks once the microbes start partying in it.
