Definition of 'windmill' Word forms: plural windmills. countable noun. 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.

Windmill The first practical windmills had sails that rotated in a horizontal plane, around a vertical axis. According to Ahmad Y. al-Hassan, these panemone windmills were invented in eastern Persia as recorded by the Persian geographer Estakhri in the ninth century.

- Learn how long humans have been using windmills, how big wind turbines can be, how much of the world’s electricity is generated from wind power and much more. Wind power involves turning energy from the wind into other forms of useful energy. Wind power can be harnessed in a number of different ways.For example, windmills create mechanical energy, sails move boats and wind turbines generate electricity.Windmills have been around for a long time, they were used in Persia (Iran) as far back as 200 B.C. Wind energy is clean and renewable.Large groups of wind turbines are called wind farms. Around 80 different countries use wind power to generate electricity commercially (as of 2009). In 1997 wind power generated only 0.1% of the world’s electricity, this increased to 1.5% in 2008 and 2.5% in 2010.ind energy is clean and renewable.

windmill The definition of a windmill is an engine that makes use of the wind as its power source. Windmills grind grains, pump water, and generate electricity. The stronger the wind, the faster the rotation of the blades. The blades automatically turn the drive shaft. This process will generate the electricity.

- The Basic Information: Grist mills constructed in the early 1600's to grind corn and wheat to make flour for the early English settlers of coastal areas. Two words in this sentience reveal was the mill was constructed to do. These words are: corn and flour. To English speaking people of the 1600's and 1700's a corn mill means a mill that grinds corn and makes flour. Corn is the English generic word for grain.

Instruments A windmill anemometer is a common instrument used at weather stations to obtain the wind speed. A wind vane is used as part of the anemometer to determine the wind's direction. As the wind flows over the windmill, the speed and direction of the wind can be measured with this instrument. Some scientific anemometers use the speed of sound to measure the wind speed more precisely in three dimensions.

- Sometimes they are called windmills but wind turbine is better. A mill is place where they grind grain, usually for making flour for baking bread. In times past, water mills and windmills were places where the power in water or wind were used to turn big stones for grinding grain.

How Does a Windmill Produce Electricity? In a windmill, when wind moves the blades of the windmill that move the rotor, the rotor rotates a shaft that holds magnets in the magnetic field of the generator, generating alternating current that is sent along power lines.

Wind Energy Today, the windmill's modern equivalent - a wind turbine - can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

- The first known documented design is also of a Persian windmill, this one with vertical sails made of bundles of reeds or wood which were attached to the central vertical shaft by horizontal struts (see Figure 1a). A 19th Century American approximation of this panemone device is shown at the left (Figure 1b). Grain grinding was the first documented wind mill application and was very straightforward. The grinding stone was affixed to the same vertical shaft.

Wind Turbine History By the year 1908, the U.S. had a 72 windmills with a total capacity of 25 MW. By the onset of the 1st world war, the U.S. was producing 100,000 windmills for farm use purposes e.g. pumping water. USSR in 1931 developed a wind turbine at Yalta, which later gave way to the modern wind turbines.
