William Kamkwamba, Malawian
Meet the boy who harnessed the wind. Born in Malawi, William was only 14 years old when he built an electricity-producing windmill from junkyard scraps in order to provide a steady source of water for his family’s farm and village in Masitala Village, Wimbe. With a bicycle dynamo and chain ring, tractor fan, rubber belts and bamboo poles, William succeeded in building a functioning windmill that provided energy for two radios and four light bulbs. Fuelled by the modest success of the initial windmill, William set out to build a larger windmill to help with irrigation for his entire village. Kamkwamba is currently studying for a degree in Environmental studies and Engineering at Dartmouth College in the USA.
