The windmill also plays an important role in Animal Farm, a book by George Orwell.
Modern windmills are designed to convert the energy of the wind into electricity.
At Fort Senneville, a large stone windmill was built on a hill by late 1686, doubling as a watch tower.
Most modern windmills, more appropriately called wind turbines, are used to generate electric power.
Two builders were the Eclipse Model of Windmill (later bought by Fairbanks-Morse) and Aeromotor.
The arrival of electricity in rural areas, brought by the Rural Electrification Administration (REA) in the 1930s through 1950s, contributed to the decline in the use of windmills in the United States.
More than 20 windmills on display in the museum at Loeriesfontein, in the Northern Cape, South Africa.
Fixed windmills, oriented to the prevailing wind were, for example, extensively used in the Cyclades islands of Greece.
A windmill is a machine with rotating blades that is designed to convert the energy of the wind into more useful forms.
Today, the increases in energy prices and the expense of replacing electric pumps has led to an increase in the repair, restoration, and installation of new windmills.
The familiar lattice style of windmill blades allowed the miller to attach cloth sails to the blades (while applying a brake).
The fantail, a small windmill mounted at right angles to the main sails which automatically turns the heavy cap and main sails into the wind, was invented in England in 1745.
Don Quixote and Sancho Panza after an unsuccessful attack on a windmill by Gustave Dorй.
Windmills were often built atop castle towers or city walls, and were a unique part of a number of fortifications in New France, such as at Fort Senneville.
Windmills feature uniquely in the history of New France, particularly in Canada, where they were used as strong points in fortifications.
Original seventeenth century wooden windmill, Gettlinge, Oland, Sweden.
By mounting the body this way, the mill is able to rotate to face the (variable) wind direction; an essential requirement for windmills to operate economically in North-Western Europe, where wind directions are various.
Prior to the 1690 Battle of Quйbec, the strong point of the city's landward defenses was a windmill called Mont-Carmel, where a three-gun battery was in place.
The Netherlands is well known for its windmills.
Windmills and related equipment are still manufactured and installed today on farms and ranches, usually in remote parts of the western United States where electric power is not readily available.
A windpump is a type of windmill used for pumping water from a well or draining land.
Most modern generations of windmills are more properly called wind turbines, or wind generators, and are primarily used to generate electric power.
Vertical axle windmills were first used in eastern Persia (Sistan) by the ninth century C.E., as described by Muslim geographers.
Horizontal axle windmills of the type generally used today were invented in Northwestern Europe in the 1180s.
Trimming the sails allowed the windmill to turn at near the optimal speed in a large range of wind velocities.
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click on the image to see an animation of wind at work.
The earliest known wind powered grain mills and water pumps were used by the Persians in A.D. 500-900 and by the Chinese in A.D. 1200. The first windmill manufactured in the United States was designed by Daniel Halladay, who began inventing windmills in 1854 in his Connecticut machine shop.
By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East. New ways of using the energy of the wind eventually spread around the world.
Historically, windmills in Holland served many purposes. The most important probably was pumping water out of the lowlands and back into the rivers beyond the dikes so that the land could be farmed. In the fourteenth century, hollow-post mills were used to drive scoop wheels to drain the wetlands.
A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Centuries ago, windmills usually were used to mill grain (gristmills), pump water (windpumps), or both.
Snowball proposes the windmill to ease the animals' heavy burden of work. The original hope was for the windmill to produce "electrical power." ... Not only is the windmill being used to grind more and more corn, but Napoleon demands a second windmill to be built, again for the dictator's own use.
