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.
