Maker Faire Africa 2012, Lagos

There are a number of kids at this year’s Maker Faire Africa, and it’s a real treat to see what they’re coming up with.

Odo Gerald is a quiet 15 year old boy who loves to make things. At Maker Faire Africa this year, you’ll find his table surrounded by all the other little boys whenever he flips the battery on. That’s because he’s got the coolest toys around by far, all manner of heavy equipment machines that operate by batter and hydraulics. Odo has 4 toys he’s made over the last 4 months. They’re made of painted plywood, syringes, wooden pieces, wire, water and small tubes along with a motorcycle battery to run it all. His next big project is to make a small helicopter that he can get off the ground.

Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls. The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15).

1 Liter of urine gives you 6 hours of electricity.

The system works like this:

  • Urine is put into an electrolytic cell, which separates out the 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.

 
Along the whole way there are one-way valves for security, but let’s be honest that this is something of an explosive device…

More on some of the other projects later.
