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. which fact about malawi the reader understand what the excerpt is mostly about?
