Inventor and author William Kamkwamba returns to the TED stage a decade after his TEDGlobal 2007 talk in which he spoke about building a windmill for his community at the age of 14. In conversation with TED Curator Chris Anderson, he shares with us where his dreams and accomplishments have taken him.

William’s original TED talk when he was 19 years old. When he was just 14 years old, Malawian inventor William Kamkwamba built his family an electricity-generating windmill from spare parts, working from rough plans he found in a library book.
