Hacker rewarded for creating electricity

diy_windmill

[garhol] tipped us off about a self-taught hacker who brought a little light to his tiny home. [William Kamkwamba] dropped out of school because his family lacked the $80 per year for tuition. At the age of 14 he read books from the library and gained the knowledge he needed to built a 12 watt wind generator from junk parts. Wow!

We’re pretty used to hearing about creative people who end up getting punished for their hacks. Fortunately he has been rewarded for his brilliance. He’s now studying at the African Leadership Academy in Johannesburg with a well-deserved scholarship.

His story comes to the surface now because a book about his experiences has just been released. We need more people like this, and they should be rewarded for their efforts like he has been. We’ve put the book on our hold list at our Public Library and can’t wait to gain some knowledge from [William's] experiences.

Check out his short talk at the TED conference, embedded after the break. [Read more...]

DIY vertical axis wind turbine

This vertical axis wind turbine (VAWT) uses five 3” PVC pipes cut in half for blades rotating on three kids bicycle wheels to spin an Ametek 38 volt motor or a wind blue alternator. The whole thing spins in a frame that is a 12 feet high and 2 foot square box that is able to sit on his deck. In total it cost him about $125 plus time, a bit more if you use the wind blue alternator.
