On a continent woefully short of electricity, 20-year-old William Kamkwamba has a dream: to power up his country one windmill at a time.
So far, he has built three windmills in his yard here, using blue-gum trees and bicycle parts, the first when he was just 14. His tallest, at 39 feet, towers over this windswept village, clattering away as it powers his family's few electrical appliances: 10 six-watt light bulbs, a TV set and a radio. The machine draws in visitors from miles around. (Wall Street Journal)
