Le generateur d'urine

invention...intéressante...les médias ne parlent pas de cette manifestation...l'Afrique est riche en pétrole, en minerais de toute sorte....où est le pognon ?....de l'urine ?...avec ce put...de soleil, pas de centrale solaire???
ça change de l'ambition de devenir Beyonce....
 14-year-olds Duro-Aina Adebola, Akindele Abiola, Faleke Oluwatoyin, and 15-year-old Bello Eniola have created a urine power generator

 All over Africa, young men and women have missioned across the country and arrived in Lagos, Nigeria. All they want to do is show off what they have made. Maker Faire Africa is more than your typical startup event: it actually shows off innovations, inventions, and initiatives that solve immediate challenges and problems, and then works to support and propagate them. Put another way, this isn’t just a bunch of rich people talking about how their apps are going to change the world.
These four girls may not end up doing that either, but their efforts definitely stand more of a chance than yet another hyper local social cloud app. Their efforts should not go unnoticed, because if this is what they’re doing as teenagers, I really hope they have the funding they need to be revolutionizing lives when they’re adults.
Here’s how it works:
  • Urine is put into an electrolytic cell, which cracks the urea into nitrogen, water, and 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.
  • 1 Liter of urine gives you 6 hours of electricity.
