William Kamkwamba is the Malawian “boy who harnessed the wind”. In 2002, William used blue gum trees, bicycle parts, and materials from a local scrap yard to create a power source for his village. Since then, he has built a solar-powered water pump and two other windmills. In 2013, Time Magazine named William one of the “30 People Under 30 Changing the World”. See his TED Talk presentation1
