Lunch over IP on young Malawi windmill inventor:

William Kamkwamba, a 15-year-old Malawian (…) built a windmill in his rural village based on a picture he saw in a book. He used old bicycle parts, wooden poles, plastic pipes, and an old car battery for energy storage. The windmill now powers four lights and two radios in his home, and he’s working on a larger model to help with irrigation. After he told his story on stage, a number of TED attendees banded together to support him financially to complete high school and go onto university.
