Windmill

OverviewForerunnersHorizontal windmillsVertical windmillsMechanicsSpread and declineWind turbinesSee also

A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (gristmills), but in some parts of the English-speaking world the term has also been extended to encompass windpumps, wind turbines, and other applications. The term wind engine is also sometimes used to describe such devices.
