A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Centuries ago, windmills usually were used to mill grain, pump water, or both. Thus they often were gristmills, windpumps, or both. The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater.
The windwheel of the Greek engineer Heron of Alexandria in the first century is the earliest known instance of using a wind-driven wheel to power a machine. Another early example of a wind-driven wheel was the prayer wheel, which has been used in Tibet and China since the fourth century. It has been claimed that the Babylonian emperor Hammurabi planned to use wind power for his ambitious irrigation project in the seventeenth century BCE.
The first practical windmills had sails that rotated in a horizontal plane, around a vertical axis. According to Ahmad Y. al-Hassan, these panemone windmills were invented in eastern Persia as recorded by the Persian geographer Estakhri in the ninth century. The authenticity of an earlier anecdote of a windmill involving the second caliph Umar (AD 634–644) is questioned on the grounds that it appears in a tenth-century document. Made of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water, and were quite different from the later European vertical windmills. Windmills were in widespread use across the Middle East and Central Asia, and later spread to China and India from there.

Windmill Failures Nearly 120 wind turbines catch fire each year, according to a research - ten times the number reported by the industry. The researchers claim that out of 200,000 turbines around the world, 117 fires take place annually - far more than what is reported by wind farm companies. Fire has a huge financial impact on the industry; Each wind turbine costs more than £2 million and generates an estimated income of more than £500,000 per year. Any loss or downtime of these valuable assets makes the industry less viable and productive. Fires are a problem for the industry, impacting on energy production, economic output and emitting toxic fumes, this could cast a shadow over the industry’s green credentials. Wind turbines catch fire because highly flammable materials such as hydr...
In the middle of nowhere in the Southern California desert are thousands of windmills providing electricity to surrounding cities. It's a magnificant sight against the beautiful mountains.

I dont want to care
but I have to stop and stare
watch my house burn down
as the flames dance around
I dont want to breathe
all the memories that I see
from the house that used to be
thats where I used to be
Kick the dust Im moving on
Dont care where Im coming from
Windmill keep on turning
As my life goes burning away
Burning away
Windmill keep on turning
Keep turning
Keep turning away
Left here standing still
No more bitter pills
But I cant leave this hill quite yet
Until the moonlight starts to set
The roaring of the flames
It overtakes the shame
The framework crumbles to the ground
But my ears cant hear a sound
Ill be waiting for the sun
With heavy sails spinning up above
Windmill keep on turning
As my life goes burning away
Burning away
Windmill keep on turning
Keep turning
Keep turning away
Just the slightest breeze
Keeps the house burning
Keeps the windmill turning
Windmill keep on turning
As my life goes burning away
Burning away
Windmill keep on turning
Keep turning
Keep turning
Windmill keep on turning
As my life goes burning away
Burning away
Windmill keep on turning
Keep turning
