Maker Faire Africa is more than your typical startup event: it actually shows off innovations, inventions, and initiatives that solve immediate challenges and problems, and then works to support and propagate them.

This four girls 14-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola have created a urine powered generator.

Their efforts should not go unnoticed, because if this is what they’re doing as teenagers, I really hope they have the funding they need to be revolutionizing lives when they’re adults.

Here’s how it works:

  • Urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and 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.
  • 1 Liter of urine gives you 6 hours of electricity.
