What a great story. William Kamkwamba built a wind turbine from whatever he could scrounge up.
“William went about collecting the parts for a wind turbine from trash heaps and junkyards. He used old plastic pipes, a broken bicycle, a tractor fan, sticks, and bits of wire. He soldered the electrical components together using a piece of wire heated in a fire, and used a bent bicycle spoke as a wrench adapter.”
