About 3 years ago the story about the Malawian boy, William Kamkwamba, that rose to fame because he built windmills out of literally waste was circulated all over the internet. Since then he has spoken at TED and with many media outlets. Since his first windmills, he has built four more, and is now speakign at many shows, conferences, and this week will be on the Daily Show with Jon Stewart.
This past week, a book on this boys journey was released entitled “The Boy who Harnessed the Wind”.
