Four girls from Nigeria showcased a urine powered generator system they developed at the Maker Faire Africa just held in Lagos.
Here is how it works:
- 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 then pushed into the generator.
I am very skeptical about the alluded ratio of 1 litre of urine generating 6 hours of electricity; it is highly unlikely. Nonetheless, this is a great start for the girls and given the right tools and guidance they could be headed for great things.
