Kid in Malawi homebrews a windmill generator

Tom sez, "With sticks lashed together, a bicycle wheel, a bike generator and rudimentary information gleaned from a primary school text, a Malawian teenager built a wind power system for his house. As others heard of his work, they and his family members chipped in to improve his system. He now provides lighting for his parents' home, and battery charging for his neighbors. His blog (with pictures) is wonderful."
