Going green may now involve something a bit yellow, as four teenage girls show off a urine-powered generator at Makers Faire Africa.
The small group of 14 and 15 year old girls had the ingenuity and inspiration to help change world with one bathroom trip at a time. Imagine powering your house or charge you electronic devices after making a trip to the little boy or girls room. It takes only one liter of urine to run the generator for 6 whole hours.
The machine works by putting urine into an electrolytic cell, which separates out the hydrogen. Then, the hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder. After that, the gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas. Finally, this purified hydrogen gas is pushed into the generator.
Do you have any genius and world-changing ideas that you wish you could create, or would you ever use this miracle machine in your own home?
