Teenage Girls Invent Pee-Powered Generator : via @TreeHugger

November 10, 2012
TreeHuggerA urine-powered generator was presented at Maker Faire Africa in Lagos by Duro-Aina Adebola (age 14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15), and according to the Maker Faire Africa blog, 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.
  • NOTE: Kinda neat project by a group of creative young woman but looks like another browns gas example (more energy consumed)
