windmill

Definition of windmill in English English dictionary: To rotate with a sweeping motion
She ran down the hill, windmilling her arms with glee.; A dunk where the dunker swings his arm in a circular motion before throwing the ball through the hoop; A guitar move where the strumming hand mimics a turning windmill; The false shower; A child's toy consisting of vanes mounted on a stick that rotate when blown by a person or by the wind; The structure containing such machinery; Of a rotating part of a machine, to become disengaged and rotate freely
The axle broke and the wheel windmilled in place briefly before careening through the wall.; A machine which translates linear motion of wind to rotational motion by means of adjustable vanes called sails; {n} a mill turned by the wind alone; a mill that is powered by the wind; A mill operated by the power of the wind, usually by the action of the wind upon oblique vanes or sails which radiate from a horizontal shaft; A device that uses wind power to mill grain into flour But informally used as a synonym for wind generator or wind turbine, and to describe machines that pump water with wind power; {i} device which harnesses the power of the wind by means of large blades which rotate around a shaft from the force of the wind (especially used to pump water, power a millhouse, or generate electricity); A childs toy consisting of vanes mounted on a stick that rotate when blown by a person or by the wind; (wind) In a strictly technical sense, only those wind-powered MACHINEs that drive mills to grind grain However, the term is generally used to describe WIND MACHINEs of all kinds A windmill is powered by wind pressure, and usually has a slowly turning ROTOR with two or more BLADEs attached to it The blades are turned by the wind, thus rotating the rotor and the WIND SHAFT In this way, WIND ENERGY is converted to mechanical energy Some typical windmill applications include water pumping, milling or threshing, and electricity generation F - moulin a vent, eolienne S - molino de viento; A windmill is a building with long pieces of wood on the outside which turn around as the wind blows and provide energy for a machine that crushes grain. A windmill is also a similar structure that is used to convert the power of the wind into electricity. Machine for harnessing the energy of the wind using sails mounted on a rotating shaft. The sails are mounted at an angle or are given a slight twist, so that the force of wind against them has two components, one of which, in the plane of the sails, causes rotation. Like waterwheels, windmills were among the original prime movers that replaced human beings as a source of power. Their most important traditional use was for grinding grain, though in certain areas their use in land drainage and water pumping was equally important. Windmill use became increasingly widespread in Europe (particularly the Netherlands) from the 12th century to the early 19th century, but thereafter slowly declined. Interest in windmills for generating electric power revived in the 1970s. See also wind power; A WECS that is used to grind grain, and that typically has a high-solidity rotor; commonly used to refer to all types of WECS; generator that extracts usable energy from winds a mill that is powered by the wind; a one-handed brooming throw similar to a softball pitch; (basketball) A dunk where the dunker swings his arm in a circular motion before throwing the ball through the hoop; generator that extracts usable energy from winds; technically, a wind powered machine used to grind grain for flour
