making its debut at maker faire africa 2012 in lagos, nigeria, a group of teenage girls have developed a urine-powered electricity generator. the system works by separating the hydrogen from the ‘yellow stuff’ with an electrolytic cell. a gas cylinder then pushes the hydrogen into a liquid borax container, removing the moisture from the substance, resulting in a purified version of the gas that can be used for fueling the machine. conceived using one-way valves as a security measure, the energy source provides six hours of electricity for every liter, which isn’t too bad considering how often humans go to the washroom.

view of the set up and its components


  • Why am i 100% sure this is a scam?
    is it the 2 fuel tank CLEARLY visible? … maybe not, maybe they are financed by the notorious prince form the area the has way too much money.

    Alex says:
  • Umm…why not just use water?

    Sam says:
  • Thanks so much, Chris…would that the rest of the commenters on this site contribute according to your example.

    Chaszr says:
  • When do people learn that hydrogen is not an energy source, but just a way to store energy? In the situation above is electricity required to make fuel for the generator (hydrogen), which generates electricity again…

    Simon says:
  • it isn’t a scam although I am surprised at the output, the key component is the electrolytic cell, it requires electricity but far less than extracting hydrogen from water [which would use all the energy and some more from the generator]. So the input is electricity [how much, I don’t know] makes the hydrogen which fuels the generator. Scientists are working on a fuel cell where urine [urea] combines across a membrane with oxygen to produce electricity without combustion.

    jules says:
  • Thanks for the article chris, but even with the improved efficiency of extracting hydrogen from urea, you are still producing hydrogen at a loss. It require more electric energy than the hydrogen energy you can get out.
    using the electricity to charge a battery is still more efficient than this. so it’s not even a good way to store energy.

    So unless the fuel cell shown as a COE of more than 1, it is not useful. The internet is full of stuff like that.
    Also, fuel tank

  • if it is worth why cant be used for substitution for petrol
