Urine Powered Generator by 4 Nigerian Teenage Girls

A urine powered generator

Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls. The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15).

1 Liter of urine gives you 6 hours of electricity.

The system works like this:

  • 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.

Along the whole way there are one-way valves for security, but let’s be honest that this is something of an explosive device…

Note: This is an experiment more than a real new tool for electricity generation. The net power output is negative due to the energy needed to get the hydrogen from the urine through electrolysis.

I’ve been blogging most of this on the Maker Faire Africa blog, so go there to find more posts on the stories from Lagos, Nigeria and the innovative and fun products made there.
