Book Summary – “The Boy Who Harnessed the Wind”
At the heart of the book “The Boy Who Harnessed the Wind” is the captivating and inspiring narrative of an entrepreneurial African teenager who built a windmill from scrap to bring electricity to his entire community.
William Kamkwamba was born in Malawi, a country where magic reigned and modern science was a mystery. It was also a land marked by drought and famine, a place where hope and opportunity were hard to come by. 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, transforming his life and those around him. His neighbors may have mocked him and called him “misala” – crazy – but William was determined to show them what a little determination and ingenuity could do.
Fascinated by electricity since childhood, William set his sights on studying sciences at the best boarding schools in Malawi. But in 2002, his country was hit by a famine that left his family’s farm devastated and his parents penniless. Unable to pay the eighty-dollar annual tuition fee for his education, William was forced to drop out of school and help his family search for food, as thousands across the country starved to death.
However, William refused to give up on his dreams. With nothing but a handful of cornmeal in his stomach, a small stack of forgotten science textbooks, and an armor of curiosity and determination, he embarked on a daring plan to bring his family luxuries that only two percent of Malawians could afford and the West considered a necessity – electricity and running water. Using recycled metal, tractor parts, and bicycle halves, William forged a rudimentary windmill, an unlikely invention and small miracle that eventually powered four lights, complete with homemade switches and a circuit breaker made of nails and wires. A second machine powered a water pump that could combat the drought and famine that loomed every season.
Soon, news of William’s “electric wind” reached beyond his home, and the boy once called crazy became an inspiration to people around the world.
This is the remarkable story of human ingenuity and its power to overcome overwhelming adversity. “The Boy Who Harnessed the Wind” will inspire anyone who doubts the power of individual ability to change one’s community and improve the lives of those around them.
