6. How a Windmill Works A windmill is a device for harnessing the power of the wind. A windmill has a large rotational disc fixed to an axle. The disc has angled sections called vanes. The axle is geared to a shaft, which turns with the axle. The shaft is connected to a device such as a pump, generator, or belt drive wheel. When the wind blows the force of the wind is deflected by the angled vanes and thus pushes them in one direction. The rotation of the disk is transferred through the turning shafts to the machines to which it is connected. A well-designed windmill can produce a great amount of cheap non-polluting energy. The energy can perform many tasks depending on the appliance to which it is connected.
