Teenage girls in Africa entered a science fair in Lagos in November, 2012 unveiling a device of their own invention — a urine-powered generator.

The collaborators, ages 14 to 15, said their device generates one hour of electricity from one liter (about a quart) of urine and described the process like this:

  • 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.
