In 2002, during Malawi's worst droughts, 14 year old William Kamkwamba had to forego schooling, since his family couldn't pay his fees. Based on a book in a library, he made, in three months, a Windmill!
His "resources" : spare bicycle parts, a tractor fan blade and an old shock absorber, and fashioned blades from plastic pipes, flattened by being held over a fire. He bolted the pieces using a screwdriver made of a heated nail attached to a corncob.
This is the subject of the book "The Boy Who Harnessed the Wind" by Bryan Mealer
