When you can watch the film…”The Boy Who Harnessed the Wind” … based on the true story of… William Kamkwamba, a Malawian innovator and author. He gained fame in his country in 2002 when he built a wind turbine to power multiple electrical appliances (including a welk water pump that saved them from starvation) using blue gum trees, bicycle parts (including a bike light rim dynamo), and materials collected in a local scrapyard. #wp #bicycle #bicyclepoweredmachines
