An interesting and inspiring story of William Kamkwamba, a man who studied at the library at age 15, came home to his relatively remote dwelling, and built a windmill that generates electricity. As he modestly puts it, he didn’t follow the book by the letter, but used it more as background reading to get a better understanding of the materials used. Then he used some wood and scrap materials to make the windmill. The voltage output is about 12 volts, and that is enough to power four lights and two radios for his home. He desires to go on to create more windmills, for his village. The plan for the next one is for it to be double the voltage, for use with irrigation and water pumping.
