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.

Mimi and Toutou’s Big Adventure

Mimi and Toutou’s Big Adventure: The Bizarre Battle of Lake Tanganyika

by Giles Foden
[cover name=mimiandtoutousbigadventure]

If you think history is boring, you should read this book. History isn’t all names and dates. Sometimes it’s crazy people doing stupid things, and in this case, it’s both amazing and hilarious.

When World War I breaks out, the Royal Navy of Great Britain is ordered to destroy the German fleet wherever it can be found. This includes Lake Tanganyika, a massive lake in Africa. The Germans have a steamship on it that the British want to sink so they can carry troops across the lake.

Unfortunately, the British don’t have any warships on Lake Tanganyika. They don’t have much of anything there. The Belgians had a ship, but the Germans destroyed it. They can’t send the parts and build a ship at the edge of the lake. The Belgians tried that, too, but the Germans have spies everywhere, and they would destroy the ship before it launched. The only logical solution is to take two small gunboats, ship them to Africa, load them onto a train, take them as far as the tracks went, and then carry them the rest of the way across Africa. Sure. That makes sense.

With a plan that is this good, the Royal Navy needs the best officers they can get to carry it out. They pick Lt. Commander Geoffrey Spicer-Simson, the oldest Lt. Commander they have. Although he has barely been involved in the war, he has already managed to sink two ships and nearly destroy a submarine – all of them on his own side. He has been court martialled twice, once for running his destroyer onto a beach (not counted as one of his two kills) and once for accidentally ramming and sinking another ship. As if Geoffrey isn’t enough, the Royal Navy picks out a few more goofy people to send to Africa along with him.

Somehow these misfits and their gunboats make it to Lake Tanganyika and actually manage to cause the Germans some serious trouble. They don’t quite do everything they had hoped to do, but at least Geoffrey Spicer-Simson can now claim to have attacked a German ship. In fact, Lt. Commander Spicer-Simson is the first Royal Navy officer to capture a German ship in the war.

The Radioactive Boy Scout

The Radioactive Boy Scout: The True Story of a Boy and His Backyard Nuclear Reactor

by Ken Silverstein
[cover name=theradioactiveboyscout]

How would you like to come home one day and find people from the Environmental Protection Agency in your neighbor’s yard wearing those hazmat suits that they only wear when dealing with some kind of horrible disease or nuclear accident? Well, this actually happened to the residents of Golf Manor, which is near Detroit, Michigan. The folks from the EPA were busy cutting up a shed and sealing away all the parts in big canisters with radioactive warning signs on them.

What happened? Well, the seventeen-year-old boy who lived next door, David Hahn, was building a nuclear reactor in his back yard. Why? Well, he had always loved chemistry, and he may have been worried about the world eventually running out of oil. He was also a boy scout, and he had enjoyed getting his Atomic Energy badge, and he wanted to become an Eagle Scout. Very few scouts become Eagle Scouts, since it involves a really big project. Ideally, the project does not involve breaking federal laws and endangering the lives of 40,000 people, but David figured that making a nuclear reactor would still be the biggest Eagle Scout project ever.

You aren’t supposed to be able to get the material to build a nuclear reactor in the Unite States if you aren’t officially approved by the federal government, but that didn’t stop David. He pretended to be a high school science teacher (and eventually a college professor) when he wrote to various scientists for advice. He got a list of ordinary household items that contain radioactive materials, bought them in bulk, and extracted the radioactive elements. He bought or stole smoke detectors to get americium-241. Apparently he got a hundred broken smoke detectors for $1 each by claiming they were for a school project. He took tiny amounts of tritium from the sights of glow-in-the-dark plastic guns, wrote to the manufacturers claiming the sights were damaged, had them replaced, and took that tritium, too. He scraped the paint off glow-in-the-dark alarm clock hands because it contained radium-226. These clocks don’t really contain a lot of radium, but David managed to find a lot of spare paint in a clock at an antique store.

He used blowtorches, aluminum foil, coffee filters, and other household items to refine the radioactive materials he needed. Amazingly enough, most of his crazy ideas worked. He eventually decided to build a breeder reactor, which is a nuclear reactor that generates power and makes more radioactive fuel for itself. He never got the energy part working, but he did get it to produce more fuel.

Eventually David decided that the dangerous levels of radiation might be a little too dangerous, so he dismantled his reactor and put parts of it in the trunk of his car. While he was doing this, the police showed up. They were looking for a kid who was stealing tires, but they decided to check David out. You can guess what happened when he told them not to open the toolbox because it was radioactive.

There’s much more to the story, but you’ve got to read it yourself. If they put this stuff in a movie (and they might), nobody would believe it.

While this book is about science, it is not a science textbook. There are some big words, but you don’t need to know very much to enjoy the story, and what you do need to know will be explained. Basically, as long as you know that building a nuclear reactor in your bad yard is not a safe idea, you already know most of the science you need. You might even learn a thing or two. Just don’t try this at home.

You can read the first chapter online at the publisher’s website.

This book came from an article that Ken Silverstein wrote for Harper’s Magazine. You an read that article at the Harper’s site.
