Windmills

Windmills are so tall because they need to be able to tell the direction of the wind

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.

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.

A Dutch building with sails is commonly called a windmill.

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...:)

It is a mill. The wind is a power source

One can find information on windmill generators from their local libraries. One can also find information about windmill generators from online websites such as Whole Sale Solar.

Wind mills have traditionally been used to power grain mills, saw mills, and small manufacturing mills. A wind mill can also be used as a wind turbine, to generate electricity.

All the MEDC like Nepal, Afghanistan, Iraq and Wadiya

Although some LEDC like, America, England and Arabia. ooohhh and Canadia

Windmill vanes are called blades or sails. These are attached to the rotor of the windmill and capture the wind's energy to generate power or perform mechanical work.

Ummm . . . windmills use the wind to keep them turning. No biofuels are involved.

Design life is 30 years; with normal repair cycles most components have a 50% chance of being exchanged once.

I have seen 10 cm diameter models that generate a few volts & milliamps.

6000 years ago wind power was harnessed in what now is Iraq.

The hub is where the blades connect. From here the blades are turned and the rotational power is transferred (maybe through a drive-shaft and gearbox) to a generator where electricity is generated.

oops

William traveled throughout America and spoke about what he went through and how he did it. He also made a book, "The Boy Who Harnesses the Wind." Hope this helped!

A windmill generator works by harnessing the kinetic energy of the wind to turn the blades of the turbine. The spinning blades then rotate a rotor inside the generator, which produces electricity through electromagnetic induction. The electricity generated is then transferred through power lines for use.
