William Kamkwamba

William Kamkwamba (born August 5, 1987, Dowa, Malawi) is a Malawian inventor and author who worked on projects to improve the lives of his family and the residents of Masitala, the rural village in Malawi where he grew up. As a teenager, he made a windmill out of scrap materials that provided electricity to his family’s house. He wrote a memoir about that accomplishment titled The Boy Who Harnessed the Wind (2009; with Bryan Mealer). Kamkwamba also helped build windmills to provide clean water for drinking and for running an irrigation system for crops.

Early life and famine in Malawi

Kamkwamba was born to Agnes and Trywell Kamkwamba as the second of seven children and the only boy. He grew up impoverished on a farm, where his family grew corn (maize). Periods of drought and heavy rainfall led to poor harvests, which, combined with the government’s decision to sell the country’s grain reserve and other factors, led to a famine that began in 2001, when Kamkwamba was 14 years old. His family could no longer afford to send him to school, so he dropped out.

Building the windmill

However, Kamkwamba continued his studies on his own by borrowing books from a small library in the village. One of the books, an American textbook titled Using Energy, inspired him to build a windmill that could power his family’s home. Since Kamkwamba could not read English, he used the book’s illustrations to build the windmill from scrap material, including tractor and bicycle parts, plastic pipes, and tree branches. The 16-foot- (5-meter-) high windmill was able to power four lights and two radios, and soon neighbors arrived to charge their cell phones. Kamkwamba went on to build other windmills—for generating electricity and pumping water—in his village.

Recognition and acclaim

News of Kamkwamba’s success spread, first appearing in The Daily Times, a newspaper in Malawi, and then in newspapers and on websites all over the world. Kamkwamba soon gained financial and mentoring support and was able to return to school after five years. He attended secondary schools in Malawi before enrolling in the African Leadership Academy in Roodepoort, South Africa, from which he graduated in 2010. Kamkwamba then attended Dartmouth College in Hanover, New Hampshire, and graduated with a degree in environmental studies in 2014.

Projects and adaptations of The Boy Who Harnessed the Wind

Meanwhile, in 2008 Kamkwamba had cofounded the Moving Windmills Project, an organization that works with residents of the Masitala area on such projects as drilling wells for clean water and installing solar panels at schools and community centers to provide consistent electricity. The organization also works with young Malawians to create simple solutions to everyday farming challenges. Kamkwamba’s memoir, The Boy Who Harnessed the Wind, was adapted into a children’s book (2012) and a feature film (2019) by Chiwetel Ejiofor, who also starred and directed.
