I have written about William Kamkwamba before: Inspirational Engineer – Home Engineering: Windmill for Electricity. And along with the post, Make the World Better, donated to his cause. His new book, The Boy Who Harnessed the Wind, is quite enjoyable and provides an interesting view of how he persevered. His talk of the famine, not being able to afford school and putting together a windmill using scrape parts and a few books from the library (donated by the American government – much better foreign aid than all the military weapons that are often counted as aid) is inspirational. And should help many sitting in luxury understand the privileged lives they lead.
“I’d become very interested in how things worked, yet never thought of this as science. In addition to radios, I’d also become fascinated by how cards worked, especially how petrol operated an engine.
How does this happen? I thought?
Well, that’s easy to find out – just ask someone with a car… But no one could tell me… Really how can you drive a truck and not know how it works?” (page 66)
“Using Energy, and this book has since changed my life… All I needed was a windmill, and then I could have lights. No more kerosene lamps that burned out eyes… I could stay awake at night reading instead of going to bed at seven with the rest of Malawi. But most important, a windmill could also rotate a pump for water and irrigation.” (page 158)
William set out to demonstrate his windmill for the first time to a skeptical crowd saying (page 193)
“Let’s see how crazy this boy really is.”… “Look,” someone said. “He’s made light!”… “Electric wind!” I shouted. “I told you I wasn’t mad!”
I like how the story shows how long, hard work, reading, experimenting and learning is what allowed William to success (page 194-5)
For the next month, about thirty people showed up each day to stare at the light. “How did you manage such a thing?” They asked. “Hard work and lots of research,” I’d say, trying not to sound too smug…
[to William's father] “What an intelligent boy. Where did he get such ideas?”
“He’s been reading lots of books. Maybe from there?”
“They teach this in school?”
“He was forced to drop. He did this on his own.”
The diagram demonstrated twenty-four volts being transformed to two hundred forty. I knew voltage increased with each turn of wire. The diagram showed the primary coil to have two hundred turns, while the secondary had two thousand. A bunch of mathematical equations were below the diagram – I assumed they explained how I could make my own conversions – but instead I just wrapped like mad and hoped it would work. (page 200)
Soon I was attacking every idea with its own experiment. Over the next year, there was hardly a moment when I wasn’t planning or devising some new scheme. And though the windmill and radio transmitter had both been successes, I couldn’t say the same for a few other experiments. (page 215)
William is now attending the African Leadership Academy in South Africa, with an amazing group of classmates. See how you can support the Moving Windmills Projects.

Unless We Take Decisive Action, Climate Change Will Ravage Our Planet
Posted on December 6, 2009 Comments (6)
Tomorrow 56 newspapers, in 45 countries, are taking the unprecedented step of publishing the same editorial. The editorial will appear in 20 languages, as the United Nations Climate Change Conference is set to begin in Copenhagen.
Climate change has been caused over centuries, has consequences that will endure for all time and our prospects of taming it will be determined in the next 14 days. We call on the representatives of the 192 countries gathered in Copenhagen not to hesitate, not to fall into dispute, not to blame each other but to seize opportunity from the greatest modern failure of politics. This should not be a fight between the rich world and the poor world, or between east and west. Climate change affects everyone, and must be solved by everyone.
The science is complex but the facts are clear. The world needs to take steps to limit temperature rises to 2C, an aim that will require global emissions to peak and begin falling within the next 5-10 years.
…
Few believe that Copenhagen can any longer produce a fully polished treaty; real progress towards one could only begin with the arrival of President Obama in the White House and the reversal of years of US obstructionism. Even now the world finds itself at the mercy of American domestic politics, for the president cannot fully commit to the action required until the US Congress has done so.
…
the rich world is responsible for most of the accumulated carbon in the atmosphere – three-quarters of all carbon dioxide emitted since 1850. It must now take a lead, and every developed country must commit to deep cuts which will reduce their emissions within a decade to very substantially less than their 1990 level.
…
The transformation will be costly, but many times less than the bill for bailing out global finance — and far less costly than the consequences of doing nothing.
Many of us, particularly in the developed world, will have to change our lifestyles. The era of flights that cost less than the taxi ride to the airport is drawing to a close. We will have to shop, eat and travel more intelligently. We will have to pay more for our energy, and use less of it.
…
Kicking our carbon habit within a few short decades will require a feat of engineering and innovation to match anything in our history. But whereas putting a man on the moon or splitting the atom were born of conflict and competition, the coming carbon race must be driven by a collaborative effort to achieve collective salvation.
…
The politicians in Copenhagen have the power to shape history’s judgment on this generation: one that saw a challenge and rose to it, or one so stupid that we saw calamity coming but did nothing to avert it. We implore them to make the right choice.
Most of the newspapers have taken the unusual step of featuring the editorial on their front page. Even with the overwhelming evidence and tremendous consequences I don’t expect politicians to make the right decisions. We know full well what the choices are. We just choice to avoid the unpleasant choices. To bad so many that don’t get to choose are going to suffer. The politicians will be weak. They will play to those that pay them money. They will delay taking important steps now. We have chosen to elect non-leaders for quite some time. We can’t really expect them to act with courage, vision, wisdom and leadership given who we elect. The politicians are responsible for their failing but we are more responsible for electing them. Some politicians, even now, do possess fine qualities but not nearly enough. Maybe I will be proven wrong, but I doubt it.
