windmill Definition, History, Types, & Facts Britannica

The vertical windmill, with sails on a horizontal axis, derives directly from the Roman water mill with its right-angle drive to the stones through a single pair of gears. The earliest form of vertical mill is known as the post mill. It has a boxlike body containing the gearing, millstones, and machinery and

US4115027A Vertical windmill Google Patents

Vertical axis windmills employing aerodynamic lift rather than differential drag have come to be of some interest as a means for employing wind energy to do work. Such vertical windmills are quite efficient and are able to derive power from the wind regardless of the wind direction. In theory, the upper limit of performance of differential drag windmills, or panemones, is 13 percent of the

A Vertical Windmill Advantage Environment

Vertical-axel windmills need fewer moving parts than traditional designs, keeping maintenance costs lower. Turbines with blades that revolve on a vertical rather than horizontal axis can improve the efficiency of clean wind generators, according to the Swedish manufacturer Vertical Wind. Based in the university town of Uppsala, north of Stockholm, Vertical Wind aims to become the nation’s

The vertical windmills of Campo de Criptana were immortalized in chapter VIII of Don Quixote. The first windmills in Europe appear in sources dating to the twelfth century. These early European windmills were sunk post mills. The earliest certain reference to a windmill dates from 1185, in Weedley, Yorkshire, although a number of earlier but less certainly dated twelfth-century European

Turbine Wind turbines Encyclopedia Britannica

Turbine Turbine Wind turbines: Modern wind turbines extract energy from the wind, mostly for electricity generation, by rotation of a propeller-like set of blades that drive a generator through appropriate shafts and gears. The older term windmill is often still used to describe this type of device, although electric power generation rather than milling has become the primary application.

Power for Technology: Wind Encyclopedia

Vertical Windmills. Vertical windmills are much larger and more powerful than horizontal windmills, and they were more common throughout Europe. A vertical windmill has several blades, or sails, mounted on a horizontal shaft and set on a tall tower, where they could turn in the wind. The sails were sometimes made of wood, but frequently they were made of cloth, often in a triangular shape that

In early Middle Eastern windmills the blades that turned in the wind were enclosed in a chamber at the bottom of the windmill. The blades were attached to a vertical axle, which was attached to a millstone above. The early windmills, which are still used, could grind a ton of grain per day and generate about one-half the power of a small car.
