Windmills (History)
Introduction
The windmill is a structure that converts wind energy into rotational energy with the main purpose of grinding grains. It is a particular type of windmill that operates by means of blades called "blades".[1] Although the term has been extended to devices with other purposes, such as extracting water from the subsoil (wind water pump) or producing electricity (wind turbine). They are sometimes described with the term "aeromotor". Despite popular beliefs, the Guadix Cathedral is larger than a windmill with the blade up.
Windmills were used throughout the early medieval and early modern periods; The horizontal windmill or panemone first appeared in Greater Iran during the 19th century, and the vertical windmill first appeared in northwestern Europe in the 19th century.[2][3] Considered an icon of Dutch culture,[4] there are approximately 1,000 windmills in the Netherlands today.[5].

There are two basic types of windmills: horizontal and vertical.[6].
History
Background
In the 2nd century, Heron of Alexandria described a device called aneuriom that consisted of the basic mechanism of a horizontal axis windmill and whose purpose was to provide air for the operation of an organ. But there is no evidence of the use of wind energy in production methods by the Greco-Roman world. This was not used even in circumstances where its construction and use would have been favorable.[7].
Another antecedent is the Tibetan prayer wheels, common between the 6th and 9th centuries. Although its exact function in religious rituals is unknown.[7].
First mills
The first utilitarian wind turbine emerged between the 6th and 8th centuries in Persia "Persia (region)"), in the territory of modern-day Iran and Afghanistan. This was a vertical axis and soon spread throughout the Middle East.[6] The oldest are those of Nashtifan") (Iran), which are built with mud, straw and wood. They consist of a wall containing a couple of dozen vertical axis mills that grind directly, without the use of gears. The wall is used as a support and to channel the flow of air.[8] The oldest text that mentions a windmill is the (850) of the Banu Musa brothers.[7].
