When searching for people to solve enormous problems like the world’s energy crisis or global warming, we never think that children might have the answers. But four teenage girls from Africa have come up with a revolutionary idea that debuted at Maker Faire Africa this week that could change the world. And certainly life in the third world. It’s a generator that runs on pee. And it’s brilliant. Here’s how it works:
– Urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and hydrogen. (Follow the link if you’re a super genius.)
– 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.
– 1 Liter of urine gives you 6 hours of electricity.
Now, who knows if your whole house ends up smelling like ammonia as a result of using this generator, but hey — if you don’t have power, your house probably already smells that way.
The inventors are 14-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola. I wish I could tell you more about them (like, for example, what country they’re from) but this is all I know. Anyway, my heart swells at what they’ve been able to accomplish, and if you can see this girls, I’m over here in New York City giving you a standing O! (But I totally get it if you’d rather have a squatting pee.)
