William Kamkwamba of Malawi was expelled from his high school for non-payment. At 14 years old he went to the library and started reading an American textbook called 'Using Energy.'

Using scrap parts and garbage, William set out to make a windmill which could provide electricity to his village. People thought the kid was nuts. Turns out he was just a genius. The windmill now brings power to many houses in his village. He's finishing another windmill to pump water for irrigation. Well played, William, well played.
