Windmills

I believe they were used for irrigation. definitely to pump water out of the ground whether for crops or not.

There are two traditional Dutch style windmills located in Golden Gate Park in San Francisco. They were originally built in 1902 and 1905 and are 75 and 95 feet high, respectively. They can be viewed, but are in need of restoration.

There are also many other windmills located in California, but are for the most part conventional and are used to generate electrical energy from wind.

Orginally windmills were used as a source of power to turn stones to grind grain and make flour. Many can still be seen in places like The Netherlands. Wind turbines are a different mechanism and are used to collect wind power as a "green" alternative to using fossil fuels to make power.
Windmills provide energy to allow things to run. They are an alternate energy source that not many use, but are very good for the environment.

They were invented around the 9th century in Persia, Greater Iran, then became popular in the Middle East and Central Asia, later widespread to China and India.

Windmills always turn counterclockwise, but this is an exception to the windmills found in Ireland.

I don't think there is another name other than blade.

you can use wood or fiberglass

Windmills stay put. The tower does not move.

The blades rotate when wind blows. Most modern wind turbines are made to start producing electrical energy when the wind blows at 3 or 4 meters per second, they achieve maximum (rated) power production in winds around 8 meters per second and shut down when the winds reach 25 meters per second. The 50 meter long (100 m diameter) blades of a 2 MW turbine rotate at about 14 rpm when the wind is 8 m/s; the tips of the blades are then moving at about 75 m/s.

Its very, very tall. The largest windmill in the world (currently) is the Enercon E-126. It's blades are just over 200 feet long and the windmill height including the blade at vertical position is around 650 feet (taller than two football fields)!

They did in fact use windmills to pump water from wells, but very little watering of crops occurred from this use. The water produced was usually only sufficient for the farm family's needs plus those of the livestock they raised. Irrigation (watering) of crops usually requires much larger volumes of water than the typical windmill of the 19th century was able to produce.

One always thinks of windmills grinding corn, and indeed this is a common use - though note that such a windmill would almost invariably belong to a miller or a Lord of the Manor rather than to a farmer. Worldwide, however, the commonest use for a windmill is for drainage - pumping the polders of Holland dry, for example, or irrigating land near rivers. For the last hundred years, they've also done a pretty good job of generating electricity.

they are giant fans that spin when wind turns the blade and then it turns the tubine to create electricty.

He was blamed because he was a political opponent of Napoleon. Napoleon also wanted all of the animals to harbor fear towards him. A common enemy makes allies.

the blades turn gears, which drive the generators to produce electricity. The controller points the windmills head into the wind to keep the blades turning rapidly.

Holland. Holland is a former province in the Netherlands, and is famous for its windmills, which kept the lowland areas from flooding by pumping lakes and bogs dry.

I am doing giant windmills in class today and I just wondered if you could answer my question for me? This is my question: 'are giant windmills used anywhere already' thankyou!!!!!! As far as I know the biggest in use now is rated at 2 megawatts

Since earliest times windmills have been used to manage water and grind grain. Holland developed windmills to pump water out of low lying lakes and lagoons. Wind power was the main source of energy after wood until the Industrial Revolution and the regular burning of coal.

Windmills have been used to pump water (for agricultural installations, for example) by gearing the windmill shaft to a pump shaft. They have also been used to charge batteries which provide electrical power in rural locations.

A windmill undergoes a transformation of energy from kinetic energy in the wind to mechanical energy in the motion of its blades. This mechanical energy is then converted into electrical energy through a generator connected to the windmill.

to get free electricity by the wind if the electricity is gone.And the main fact is there will be no environ -mental pollution...

The object that resembles this imagery is a wind chime. Just as leaves respond to the wind's gentle touch, a wind chime dances and produces melodic sounds, creating a harmonious atmosphere. Both evoke a sense of joy and connection with nature, as they react to the subtle whispers of the breeze.

The Windmills of Your Mind was created in 1968.

Windmill Theatre ended in 1964.

Windmill Theatre was created in 1931.
