A Young Tinkerer Builds A Windmill, Electrifying a Nation

MASITALA, Malawi -- On a continent woefully short of electricity, 20-year-old William Kamkwamba has a dream: to power up his country one windmill at a time.

So far, he has built three windmills in his yard here, using blue-gum trees and bicycle parts. His tallest, at 39 feet, towers over this windswept village, clattering away as it powers his family's few electrical appliances: 10 six-watt light bulbs, a TV set and a radio. The machine draws in visitors from miles around.

Self-taught, Mr. Kamkwamba took up windmill building after seeing a picture of one in an old textbook. He's currently working on a design for a windmill powerful enough to pump water from wells and provide lighting for Masitala, a cluster of buildings where about 60 families live.

Then, he wants to build more windmills for other villages across the country. Betting he can do it, a group of investors are putting him through school.

"I was thinking about electricity," says Mr. Kamkwamba, explaining how he got hooked on wind. "I was thinking about what I'd like to have at home, and I was thinking, 'What can I do?' "

The contraption causing all the fuss is a tower made from lashed-together blue-gum tree trunks. From a distance, it resembles an old oil derrick. For blades, Mr. Kamkwamba used flattened plastic pipes. He built a turbine from spare bicycle parts. When the wind kicks up, the blades spin so fast they rock the tower violently back and forth.

Mr. Kamkwamba's wind obsession started six years ago. He wasn't going to school anymore because his family couldn't afford the $80-a-year tuition.

The new power also attracted a swarm of admirers. Last November, Hartford Mchazime, a Malawian educator, heard about the windmill and drove out to the Kamkwamba house with some reporters. After the news hit the blogosphere, a group of entrepreneurs scouting for ideas in Africa located Mr. Kamkwamba. Called TED, the group, which invites the likes of Al Gore and Bono to share ideas at conferences, invited him to a brainstorming session earlier this year.

In June, Mr. Kamkwamba was onstage at a TED conference in Tanzania. (TED stands for Technology Entertainment Design). "I got information about a windmill, and I try and I made it," he said in halting English to a big ovation. After the conference, a group of entrepreneurs, African bloggers and venture capitalists -- some teary-eyed at the speech -- pledged to finance his education.
