The Boy Who Harnessed the Wind

The Boy Who Harnessed the Wind: Creating Currents of Electricity and Hope

by William Kamkwamba and Bryan Mealer

William Kamkwamba grew up in Malawi, a fairly poor country in southeast Africa. His family’s house didn’t have electricity. He had never seen a working computer. People in his village often went hungry. He wasn’t well educated – his family couldn’t afford $80 per year to keep him in school. Then he found a couple of books about physics and engineering in the local library. He studied them carefully – he had trouble reading English, so he looked at the diagrams and used them to help figure out the words. When he got to the one about windmills, he decided to build one of his own.

Building a windmill in rural Malawi wasn’t easy, since he didn’t have a local hardware store. People said he was crazy, but it worked. He figured out how it should work mostly by looking at pictures and he built it out of wood, scrap metal, an old bicycle, and PVC pipe, and it worked. People came from miles around to see it. What did the windmill do, other than turn? It powered a single light bulb. Pretty soon, though, he ran a wire into his house and had an electric light in his room. Eventually, he built a circuit breaker and switches and wired his whole house.

Quite a few people in his village had cell phones, but charging them was not easy. William decided he could do something about this. Again based mostly on pictures and working with spare parts, he built a step-up transformer so that the windmill could charge cell phones.

In my book, that’s amazing stuff from a homemade windmill. What really blows me away, though, was that William was only 14 when he built the windmill.

The Boy Who Harnessed the Wind is William’s inspiring autobiography. I try not to say “inspiring” unless I really mean it, but there aren’t that many other words I can use. This book reminds you that there really are amazing people in the world, and they can do great things.

The book starts with the day William’s got his first windmill working, but then it jumps back to cover some of his earlier life, parts of which were pretty rough. It also describes many of the events that came after that windmill – news spread around Malawi, and at some point it hit the Internet (which William had never seen), and his story made it around the world. William has spoken at two TED conferences and MIT, and he has been on The Daily Show with Jon Stewart. At the first TED conference, he got funding to build more windmills so he could use the electricity to irrigate the crops in his village. He didn’t stop there, though. William has also co-founded a non-profit organization, Moving Windmills, which promotes economic development and creates educational opportunities for the people of Malawi.

Check out William’s first TED conference presentation. He talks about this in the book. This was his first trip away from his home, so within 24 hours, he flew on his first airplane, saw his first laptop (and made a PowerPoint presentation), got his first e-mail account, and gave his first formal talk. He was fantastically nervous, but he managed to get his point across, and the audience really supported him.

Here is his second TED conference presentation. He’s a lot more relaxed.

Here he is on The Daily Show, where he explains how he built the circuit breaker for his house.

One week later he and Bryan Mealer give a talk at MIT. It’s about an hour long. The first few minutes are all other people talking, but then we get to the good stuff.

Finally, here is the short film Moving Windmills: The William Kamkwamba Story. William’s non-profit group has prepared a feature-length documentary based on this.
