The first source of windmills is an ancient Hindu book called "Artasas Tira Cantilia" in 1400 BC, in which it also referred to the rise of water. Although the windmills were unknown as a source of power in the Greek and Roman civilizations, Hero of Alexandria (260 BC) gave a description of the small tool in which the air pressure could be used for the citadel, and as never before This device was not created.
The first post-Islamic reports provide more specific descriptions of the real windmills used to grind grain and boost water.
Mas'udi (fourth century AH) in the propagator of al-Zahab has narrated a story of an Iranian worker who seems to be the maker of windmills. Massoudi also describes the wind blastlands and says, "Sistan is a river and a river, and it's the city that says that the wind returns the mills and drains the water from the wells, and the towns all over the world. It's not that much of it is out of the wind and God knows. "
One of his geographically time-consuming donors, the pool (about 951 m / 340 e), confirms this. He says:
"Here there are strong winds that make winding wheels". Ghazvini, a geographer of the following years (death in 1283 AD / 682), writes in his commentary on Sistan: "There never was The wind does not calm down and due to the mills made that all crushing of the corn is done with those wheels, there is a warm land and there are wheels that work with the wind "(Damshawk 1326-1256 m / 726- 654 e) The Syrian geographer describes how to build windmills along with the shape.
"Nutta Bar," a renowned researcher in the Netherlands, who has carried out in-depth research on windmills, writes: "... The construction of windmills in Sistan is the same. At the beginning, they form a tower like a minaret. The mill is divided into two sections: in the lower part, the rocks of Asia are located, which flours the grain through the rocks of the bottom, in the upper part of the wind that flows to the wind It moves. Due to the movement of the wheel and its axis, the bottom of the mill is rotated. After the end of this two-story building, the Sistani create four gaps in the wall. These gaps are like gaps in towers and rains. Slits get tighter inside. The wind blows through these gaps with a lot of force, as the wind blows out of the blacksmith ...
Windmills with Qa'im axis, ie Iranian windmills, arrived in China during the Mongol invasion of Iran in the 13th century. Windmills with the Islamic axis grew up and used in Egypt as one of the main sources of force for crushing sugarcane. In the 11th century, wind mills had reached the islands of the Aegean, Spain and Portugal, but there, they had a 30-degree horizontal orientation instead of a vertical milling axis. With the difference and with the view that some say: This is the reason for the separate invention of milling in those lands.
This theory can not be accepted because it came from the same way as other inventions at that time in the West and the invention of Windmill could not have been carried out separately in that area, either the fundamental difference between the two forms is negligible. The first mention of milling The wind is in northern Europe in the year 1105.
The windmills in Iran today were routinely used in Sistan. The explanation for wind turbines in wind farms in Sistan is that there is a difference between them and today's mills. The difference is that in ancient mills rocks The mill is located on top of the windmill, while in today's mills, the house is located under the blades of mills.
In Sistan, there have been a lot of windmills for a long time. Due to the existence of the blessings and the name of Sistan as the barn of Iran, and on the other hand, the existence of persistent winds, people of that time thought to make windmills whose works in the corners of Sistan It is seen. And even until recently, they were used and used, including one in the village of De Kool, behind the water of Zabul (the birthplace of the ancestors of the father of book collectors).
