William Kamkwamba

William Kamkwamba is a Malawian inventor, engineer and author, born in 1987 in Kasungu. His story matters because it shows how scrap materials and self-taught knowledge can solve real problems in a poor rural area, and it reached an international audience without him ever leaving his country.

He grew up in a farming family in the Kasungu region, where agriculture was the basis of household life. A severe famine in 2001-2002 meant his family could no longer pay his school fees, and he had to leave school. To keep learning, he spent long hours in the school library, where he found his interest in electronics. He had already set up a small radio-repair business in his village, though it brought in little money.

After reading a book called Using Energy, he decided to build a makeshift wind turbine. He tested a small model with a cheap dynamo and eventually built a turbine that powered his father's radio and other appliances at home. Neighbours and local reporters came to see it, and the news spread first through Malawian media and then online. Since then he has built further turbines, a windmill-driven and solar-assisted water pump, and projects to bring clean water and better schools to his community.

His profile grew after he spoke at TEDGlobal 2007 in Arusha, Tanzania, where his talk moved the audience and several investors offered to help fund his secondary education. He then studied at the African Leadership Academy in Johannesburg and graduated from Dartmouth College in 2014. His book, The Boy Who Harnessed the Wind, written with Bryan Mealer, became a common read at several universities and was adapted into a 2019 film directed by Chiwetel Ejiofor. His legacy lies mainly in showing that innovation can grow out of necessity, using whatever is at hand, even a school library.
