Windmills: What are they used for? What do they do,
Dec 20, 2016· The earliest documented windmills were vertical axis systems, with vertical sails made from reeds or wood that was attached by horizontal struts to a vertical shaft with a stone for grinding purposes. The first windmill to appear in Europe was the post mill with a horizontal axis system, with a four-bladed mill attached to a central post.
How Do Windmills Work? - Alternative-energies.net
Sep 02, 2017· Vertical windmills have become very popular in Europe in the fourteenth century reaching at peak (200,000) in 1850. Today, instead of using windmills, we are using wind turbines that are turning the power of the wind into clean electricity. A windmill is a mill that turns the energy of the wind into a rotational energy using sails or blades.
Windmill - Wikipedia
The first practical windmills were panemone windmills, using sails that rotated in a horizontal plane, around a vertical axis.Made of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. It is recorded by medieval account that the windmill technology were acknowledged in the middle east during the reign of
Wind turbine - Wikipedia
A wind turbine is a device that converts the wind's kinetic energy into electrical energy.. Wind turbines are manufactured in a wide range of sizes, with either horizontal or vertical axes. It is estimated that hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year.

Windmills were used for pumps. But shafts had to be restricted to depths of 90 to 105 metres (300 to 350 feet) and a mining radius of 180 metres. It was not until 1710 that the water problem was eased by Thomas Newcomen’s steam atmospheric engine, which supplied a cheap and reliable power source for a vertical reciprocating lift pump.
