Read the excerpt from The Boy Who Harnessed the Wind by William Kamkwamba.

The wind would spin the blades of the windmill, rotate the magnets in a dynamo, and create electricity. Attach a wire to the dynamo and you could power anything, especially a bulb. All I needed was a windmill, and then I could have lights. No more kerosene lamps that burned our eyes and sent us gasping for breath. With a windmill, I could stay awake at night reading instead of going to bed at seven with the rest of Malawi.
