"Some people see lemons and make lemonade. William Kamkwamba saw wind and made a windmill. This might not seem like a mighty feat. But Kamkwamba, who grew up in Masitala, a tiny rural farming village off the grid in Malawi, was 14 years old in 2001 when he spotted a photo of a windmill in a U.S. textbook one day. He decided to make one, hacking together a contraption from strips of PVC pipe, rusty car and bicycle parts and blue gum trees."
