Different machines to meet all needs
Windmill Uses. Windmill power was used for a number of functions, such as for pumping water, grinding grain, saw-milling of timber, drainage-pumping, and the processing of commodities such as tobacco, spices, cocoa, dyes and paints. Many small windmills are still in use on farms today, being used for water-pumping, stock-watering and farmhouse needs.

Wind turbines need an unchanging and uninterrupted flow or air to work effectively, which means there must be no obstructions nearby. Researchers have suggested that for residential wind turbines 150 meters away from nearby obstructions is enough. In the case of wind farm spacing, turbines need to be at least 7 rotor diameters away from each other.

Wind turbines and air traffic. They can even let you know that you are least 5 km from an airport. This close to an airfield means that, according to German regulations, turbine blades must have a single orange stripe on each blade. If there is no airport within 5 km the turbine blades must have two stripes.

Ideal locations for wind turbines are: in the country, on farms, or; on the coast; Basically, anywhere away from built-up areas. The more buildings around the installation, the less wind there is. Setting up a wind turbine is a big job that takes time. It can be a very cost effective way of creating power as long as the average wind speed is high enough.

To me, that's self-sufficiency and a nice sense of security. Evidently a lot of backwoods people feel that way because windmills are making a comeback. Aermotor claims that sales of windmills, both for generating electricity and for pumping water, are increasing worldwide, and more windmills are pumping water today than at the turn of the century.

Wind Turbines and the Energy in Wind. Turbine Efficiency If the turbine could convert all the wind's power to mechanical power we would say it was efficient. But as you probably know, the real world is never so generous. To even achieve 50% is unlikely, and would be a very efficient machine. A 50% efficient turbine would convert half of the power in the wind to mechanical power.
