On the Daily Show, William Kamkwamba talked about building an electricity-generating windmill for his family’s farm in Malawi, using a library book as a guide, at the age of 14. He’s since presented at TEDGlobal 2007 in Tanzania, and wrote a book, “The Boy Who Harnessed the Wind.”

Toward the end of the interview, Kamkwamba explains how he found out about Google, at the TED conference: “I was like, ‘Where was this Google all this time?’”

Kamkwamba is scheduled to speak at MIT’s Technology & Culture Forum on October 21.
