Everyone told him he was crazy.
But William Kamkwamba had a dream. He believed he could make a difference for his family and his village.
At 14 he dropped out of school because his parents couldn't afford the $80/year fee. But he still loved to learn. He borrowed books from the local library and just from the pictures (he couldn't read English!) taught himself how to build a windmill. Using scraps from the village - a tractor fan, a discarded bicycle wheel - he built a windmill that powered a radio and a light bulb.
He now has four windmills that provide electricity for families and pump water to irrigate their fields. His memoir is being published this fall.
Watch this and be inspired.
