Four African girls have created a generator that produces electricity for six hours using a single liter of urine as fuel

So how exactly does the urine-powered generator work?

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.
