What are windmills used for?

Wheel-alike

A windmill is a machine that uses the power of the wind for pumping water and generating electric power.  A windmill is a machine that uses the power of the wind to do work of some kind.  In the United States, windmills are generally to be found on farms where they serve as a cheap source or power for pumping water from wells and driving electric generators for electric power.

The kind of windmill commonly used to bump well water has a big wheel with several blades.  It is usually mounted on tail tower so that the blades will catch the full force of the win.  A tall vane acts as a rudder and keeps the wheel facing into the wind.

By the means of gears, the turning wheel provides the power to work a pump, a small electric generator, or to do some other useful job.  Of course, a windmill is not of any use unless there is enough wind to turn it.  Today, many farmers don’t use windmills to get water from their wells.  They use electric pumps to do the work because they are more dependable. Dick Rogers
