The windmill's blades act like a rotating fan which pushes the rod attached to it to the direction the wind is blowing. As it goes to the end of the rod, the stone, which is attached to the rod too spins. This causes the two stones which are joint together crush and grind the grain between them.

How is wind energy harnessed and used?
The wind turns a windmill which then turns a turbine that generates electricity using inductance. Also, more 'primitive' applications simply use a windmill to turn gears and shafts to pump water or grind grain, etc.
What is inside of a windmill?
Old windmills had grinding stones that were used to mill grain into flour, these were powered by the wind.
How is wind energy havested?
Wind energy is harvested by a windmill. It is also called a turbine. Windmills have been connected to machinery to grind grain or pump water. They are also connected to electric generators. The electricity is sent to a grid. Sometimes the electricity is used as it is produced. If a hydroelectric dam is nearby, the electricity can be used to back pump water and then hydroelectric energy is available when it is needed. That way wind energy is stored.
What makes a wind mill make wind?
it makes it by less weight and to ,make sure you put ur wind mill in a place were there is a lot of wind ============================= A windmill doesn't "make wind". The windmill is built in a place where there's plenty of wind. When the wind blows, it makes the windmill turn, and the turning is used to do useful work, like grinding grain, pumping water, or producing electricity.
How did people first use wind as energy?
Probably in primitive sailing boats. Before electricity was even known about, millers used windmills to grind grain into flour.
What is the derivation of the word windmill?
These devices were first used to harness WIND power to grind grain on a MILL stone.
Why was the windmill invented?
The earliest windmills were invented in the ninth century AD in the Middle East and were used to grind grain or to lift water.
What are the advantages and disadvantages of a windmill?
Advantages1. wind to harness electricity2. Environmentally friendly, does not produce green house gasesDisadvantages1. Reliability.The output power of a windmill depends on the speed of the wind.If wind is not strong in the area, the windmill will not generate enough power to grind grain to flour, or, will grind only some grain. Thus building windmills in this type of areas will be useless.2.Noise pollution is also another problem. When rotating, the vanes of the windmill make a considerable amount of noise.3. A lot of resources needed
What is the functions of windmill?
A windmill was used in the old days to help grind grain into flour. Today it is used to change wind or kinetic energy into electrical energy and place it out on the Electrical Grid for people to use.
What kind of work can a windmill do?
Windmills were originally used to grind grain and pump water. Recently they are used to produce electricity. See the related link for more information.
How do traditional windmills grind grain and bring underground water?
By capturing the power of the wind as it passes the windmill's sails. This causes the sails to turn, which rotates the sails axle and this, through gears and cogs, powers the pump or the grind stones.
A place where people grind grain into flower?
People grind grain into flour in a mill.
How is wind energy harnessed and used?
The wind turns a windmill which then turns a turbine that generates electricity using inductance. Also, more 'primitive' applications simply use a windmill to turn gears and shafts to pump water or grind grain, etc.
What is the place to grind grain?
A mill is the place where grain is ground into flour. Mills can be powered by water, wind, or electricity, and they use grinding stones or rollers to crush the grain into a powder.
Can a windmill power light bulbs?
Yes, but it is really a wind turbine, not a windmill which used to be used to grind wheat to flour.
How do you use grind in a sentence?
The machine could grind up grain easily.
How is a windmill an alternate source of energy?
A windmill captures the energy of the wind, which is free, and uses the energy for something else. In the olden days it was used to grind grain into flour, or to pump water up a hill. It is now being used to generate electricity, without any harmful emissions of carbon dioxide.
