The inspiring story of Malawian William Kamkwamba: Unable to afford school and forced to drop out at age 14, Kamkwamba used his spare time educating himself at a local library. His interest was sparked by the sciences and in 2002, after coming across a diagram in a tattered textbook, he built a functional windmill out of scrap material and spare parts to provide the luxury of electricity to his family’s home in Masitala. Journalist Bryan Mealer turned this inspirational story into a book, The Boy Who Harnessed the Wind, and Kamkwamba has since gone on to speak at TED—he is widely seen as an emerging young leader in Africa.

William Kamkwamba was born in Malawi, a country where magic ruled and modern science was mystery. It was also a land withered by drought and hunger, and a place where hope and opportunity were hard to find. But William had read about windmills in a book called Using Energy, and he dreamed of building one that would bring electricity and water to his village and change his life and the lives of those around him. His neighbors may have mocked him and called him misala–crazy–but William was determined to show them what a little grit and ingenuity could do.

Enchanted by the workings of electricity as a boy, William had a goal to study science in Malawi’s top boarding schools. But in 2002, his country was stricken with a famine that left his family’s farm devastated and his parents destitute. Unable to pay the eighty-dollar-a-year tuition for his education, William was forced to drop out and help his family forage for food as thousands across the country starved and died.

Yet William refused to let go of his dreams. With nothing more than a fistful of cornmeal in his stomach, a small pile of once-forgotten science textbooks, and an armory of curiosity and determination, he embarked on a daring plan to bring his family a set of luxuries that only two percent of Malawians could afford and what the West considers a necessity–electricity and running water. Using scrap metal, tractor parts, and bicycle halves, William forged a crude yet operable windmill, an unlikely contraption and small miracle that eventually powered four lights, complete with homemade switches and a circuit breaker made from nails and wire. A second machine turned a water pump that could battle the drought and famine that loomed with every season.

Soon, news of William’s magetsi a mphepo–his “electric wind”–spread beyond the borders of his home, and the boy who was once called crazy became an inspiration to those around the world.

Here is the remarkable story about human inventiveness and its power to overcome crippling adversity. The Boy Who Harnessed the Wind will inspire anyone who doubts the power of one individual’s ability to change his community and better the lives of those around him.

“Biofuels” are transportation fuels like ethanol and biodiesel that are made from biomass materials. These fuels are usually blended with the petroleum fuels — gasoline and diesel fuel, but they can also be used on their own. Using ethanol or biodiesel means we don’t burn quite as much fossil fuel. Ethanol and biodiesel are usually more expensive than the fossil fuels that they replace, but they are also cleaner-burning fuels, producing fewer air pollutants.
What Is Ethanol?
Ethanol is an alcohol fuel made from the sugars found in grains, such as Corn, Sorghum and Barley. Switchgrass can yield almost twice as much ethanol as corn, estimates geneticist Ken Vogel, who is conducting breeding and genetics research on switchgrass to improve its biomass yield and its ability to recycle carbon as a renewable energy crop.
Other sources of sugars to produce ethanol include: Potato skins, Rice, Sugar cane, Sugar beets, Yard clippings, Bark and Switchgrass.
Most of the ethanol used in the United States today is distilled from corn, gving rise to concerns over world food shortages, as biofuels demand increases. Scientists are working on cheaper ways to make ethanol by using all parts of plants and trees rather than just the grain. Farmers are experimenting with “woody crops,” mostly small poplar trees and switchgrass, to see if they can be grown cheaply and abundantly.
Ethanol Is Blended With Gasoline: About 99% of the ethanol produced in the United States is used to make “E10″ or “gasohol,” a mixture of 10% ethanol and 90% gasoline. Any gasoline powered engine can use E10, but only specially made vehicles can run on E85, a fuel that is 85% ethanol and 15% gasoline.

Ethanol Is Nontoxic and Biodegradable. Using ethanol means that we use less oil (a nonrenewable fuel) to make gasoline. Unlike gasoline, ethanol is nontoxic (safe to handle) and biodegradable; it quickly breaks down into harmless substances if spilled.
Ethanol Can Reduce Pollution. When small amounts of ethanol are added to gasoline, usually less than 10%, there are many advantages. Ethanol reduces carbon monoxide and other toxic pollution from the tailpipes of vehicles, making less air pollution. It also keeps engines running smoothly without the need for lead or other chemical additives.

Ethanol is made from crops that absorb carbon dioxide and give off oxygen. So growing crops for ethanol may have the potential to balance out carbon dioxide emissions to the atmosphere. The impact of greater ethanol use on net carbon dioxide emissions depends on how ethanol is made and on whether or not indirect impacts on land use are included in the calculations.

What Is Biodiesel?

Biodiesel is a fuel made from vegetable oils, fats, or greases — such as recycled restaurant grease. Biodiesel fuel can be used in diesel engines without changing them. It is the fastest growing alternative fuel in the United States. Biodiesel, a renewable fuel, is safe, biodegradable, and produces lower levels of most air pollutants than petroleum-based products; below is a video of the backyard version of the process of making biodiesel:

Of course all this uses up land that could be used for food. This practice is better run at small-scale local levels, using waste products exclusively.

Cambridge University physicist, David Mackay, in a passionate, personal analysis of the energy crisis in the UK, in which he comes to some surprising conclusions about the way forward. The film is based on his new book Sustainable Energy without the hot air, in which Prof Mackay has calculated the numbers involved for the alternatives to fossil fuels like coal, gas and oil.

He debunks some myths about energy saving – unplugging our phone chargers, does not make any appreciable difference. After showing us what won’t work – he goes on to show what will make a difference at home, like turning your thermostat down.

But, his big point is that this will not be enough – individual efforts are not enough. Instead we need to make sweeping national changes to our energy production, and we can’t reject everything available to us. If we are going to follow the advice of climate scientists, and get off fossil fuels by 2050, which currently provide 90% of our energy, Britain’s main options are wind power and nuclear power. But to make this huge change in our power supply, Mackay says that we have to get building now!

In Permaculture alternative energy systems are an integral part of any good design. There is no better example of this than the humble bicycle. In this short fun film there are many examples of the innovative and creative uses of bicycle power.
