African girls come up with pee power

CNET - In a stroke of ingenuity that could have proven handy during Hurricane Sandy, four teenage African girls have come up with a urine-powered generator.

Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all 14, and Bello Eniola, 15, collaborated on the invention, which they claim generates one hour of electricity from one liter (about a quart) of urine.

A post on the Maker Faire Africa blog describes the generator's workings in the following words:
  • Urine is put into an electrolytic cell, which separates out the hydrogen.
  • 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.

They should definitely get full-ride scholarships for that work.

But I bet they won't.
