14-Year-Old Nigerian Girls Invent Urine-Powered Generator
The generator is on display at an exhibition in Lagos Nigeria where people from the tiniest villages to those from big cities are talking about making stuff. This is part of an initiative by 'Maker Faire Movement' which seeks to showcase how traditional handicrafts can be a solution in the wake of expensive robot.
Their invention ensures that 1 Liter of urine gives you 6 hours of electricity.
The system works like this:
1. Urine is put into an electrolytic cell, which separates out the hydrogen.
2. The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.
3. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
4. This purified hydrogen gas is pushed into the generator.
