Persian vertical-axis windmills, also known as the wind-powered panemone or the windmill of Nashtifan, are a type of traditional windmill that can be found in the town of Nashtifan, located in northeastern Iran. These windmills have been used for hundreds of years to grind grains and pump water from underground wells. https://bit.ly/3ZbvOU2
Unlike the more common horizontal-axis wind turbines, which have a propeller-like rotor that spins on a horizontal plane, the Persian windmills have a vertical rotor with multiple blades arranged in a circular pattern around a central shaft. The rotor is positioned perpendicular to the ground and is mounted on a tall vertical pole or tower. As the wind blows, it causes the rotor to rotate, which in turn drives a mechanical system that can be used to power various applications, such as grinding stones or pumping water.
The design of the Persian windmills is simple yet effective. The rotor blades are made of locally available materials such as palm leaves or woven reeds, which are light and flexible yet strong enough to withstand the wind. The vertical axis allows the windmill to operate in any wind direction without the need for a complex tracking system, and the height of the tower allows the windmill to capture the stronger, more consistent winds that exist at higher altitudes.
Despite the emergence of modern wind turbine technology, the Persian windmills continue to be used in some parts of Iran to this day, demonstrating their durability and https://bit.ly/3ZbejUb effectiveness. They are also considered an important cultural heritage and a symbol of the ingenuity and resourcefulness of the people of Iran.
