Windmills
Windmills are machines used to convert wind energy into other usable forms. They are commonly used for the pumping of water or milling of grains.

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.
Where Are The Largest Windmills?
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.
How did homesteaders use windmills?
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.
What did snowball say the windmill could do?
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.
What is bad about the windmills?
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.
Which country have the largest number of windmills?
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.
Where are windmills being used today?
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
What are some traditional uses of windmills?
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.
What type of energy transformation does a windmill have?
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.
What greatly improved life on the Great Plains by providing access to the underground water?
windmills
What are the benefits of a wind mill?
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.
Windmills are so tall because they need to be able to tell the direction of the wind
Do you plug into 120 or 240 on your generator for home use?
In the U.S. the normal voltage for appliances (refrigerators, washing machines, lamps, microwaves, computers, televisions, etc.) is 120vac. Such things as air conditioners, electric ranges, electric clothes dryers, etc. use 240vac.
What do you know about windmills?
A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails or blades. The reason for the name "windmill" is that the devices originally were developed for milling grains for food production; the name stuck when in the course of history, windmill machinery was adapted to supply power for many industrial and agricultural needs other than milling. The majority of modern windmills take the form of wind turbines used to generate electricity, or wind pumps used to pump water, either for land drainage or to extract groundwater.
How do windmills work without electricity?
Soo there is a turbine in the center of the rotating part, so when the wind make the three spikes rotate, the turbine spins generating electricity. It makes electricity; it doesnt need it. The turbine king of works like a rotor or if you know anything about hyropower elctricity then you know about the turbine that spins when water falls. So basically in windmills, the wind causes the spikes to turn making the turbine work generating power... hope it helps...:)
