Windmills

A windmill is a machine with sails or blades, usually four, driven by the wind, originally used to pump water, or grind grain,

Windmills were originally just that, a wind-powered grain mill (to turn grain into flour). Many "windmills", for instance those scattered around the Australian outback, are actually "wind pumps" to bring water from to the surface from deep underground.

Modern ones are used on wind farms that use the renewable source of energy, wind, to make energy.

The simplest part of a windmill are the rotor blades, generator and the shaft. but there are many parts when it comes to wind turbines. hope this helps!

Yes,the companies which are under Clean Development Management can avail carbon credits....

If the blade hits you in the head. Lol. What a funny questions. Can the electricity the produce kill you? Sure, if its big enough. Can the blades kill you when they spin? Sure, if they spin fast enough. Just like everything in life, if its moving fast enough - it will kill you ;)

Windmills are used to pump water over the dikes, so that the land is farmable and not flooded by sea water. Also they are used to provide electricity.

In the past they were also used to saw wood, make bread, make oils and probably some other things as well.

Since 1992, Ireland's first commercial

wind farm has been operating at

Bellacorick, Co. Mayo. The wind farm comprises 21

wind turbines with a total installed

capacity of 6.45 MW, and produces

enough electricity to supply 4,500

households.

Holland (the Netherland) is a low country. Next to the Northsea and with lots of rivers the Netherlands has been dealing with water for centuries. Building dams to keep the water at bay for instance. The Netherlands has a windy climate and uses the wind through windmills to fight the water.

Law of physics . . . energy cannot be made, and for that matter, cannot be destroyed. The only thing that you can really do with energy is to change it into a different form.

So, wind generators turn energy in the wind into energy in the form of electricity and a bit of heat. Power output is how wind generators are measured. Power size gives us an idea of how much work can be done by the electrical energy that wind generator put out. Wind generators come in many sizes (of power), from 'backyard' to huge wind farm sizes.

Windmill composed of 2 energies. One is the mechanical energy. To make it work the force of the wind allows the windmill to run and this process produces the second energy called the wind energy.

A simple windmill consists of a vertical post with two rotating hubs - one vertical, one horizontal - attached at the top. Each hub is attached to the other, allowing the windmill to rotate horizontally and point into the wind. The vertical hub has slats attached radially to it, each one at a slight angle. As the wind passes over the slats, the Bernoulli principle (high pressure/low pressure) causes the vertical hub to rotate. By itself, a windmill is just decorative, but if big enough, it can be used to rotate grist stones in mills, run pumps, etc.

Wind turbines, used in combination with other kinds of renewable energy, can slow and eventually stop global warming if we also stop burning fossil fuels (coal, oil and natural gas).

As much as it costs

As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver

it to the reciprocating pump, the suction and discharge takes place.

Most common uses are generation of electricity and pumping water (especially agricultural pumping for irrigation).

One way is to cut a piece of construction paper, staple equal-sized streamers on one side in a row ( ten is a good amount), then form a circle with the paper and staple it. Make at least 3 (6 would be better), equally spaced holes, with a hole-punch. Attach a string to each hole, tie a knot in all the strings at once, so that all the strings are equal in length and attach it to a pole (the taller, the better).

You can find dutch windmills all over the Netherlands. You can find most of the mills in the western part of the Netherlands. There are still about 1000 windmills in the Netherlands. Most popular: Kinderdijk (near Rotterdam) and Zaanse Schans (near Amsterdam).

Yes

A working model of a windmill is easy to construct from popsicle sticks. Simply place four popsicle sticks across each other at angles. Then put a nail through the middle of the sticks to attach them all together making the hole a little bigger than needed. Attach to a base.
