From Qanāt to Kort: Traditional Irrigation Terminology and ...
When a qandt is built, sometimes a water mill (dstfb) for grinding grain will be constructed into the system. The only mills that I specifically investigated in central Iran are of the type called a Norse Mill by Wulff,4 which depends on a vertical drop of 510 metres in order to power a vertical shaft, which turns a heavy mill stone.

Panemone windmill Wikipedia
A panemone windmill is a type of vertical axis wind has a rotating axis positioned vertically, while the windcatching blades move parallel to the wind. By contrast, the shaft of a horizontal axis wind turbine (HAWT) points into the wind while its blades move at rightangles to the wind's thrust. That is, a panemone primarily uses drag whereas the blades of a HAWT use lift.

Windmill Wikipedia
The first practical windmills were panemone windmills, using sails that rotated in a horizontal plane, around a vertical of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. These windmills are recorded by Persian geographer Estakhri in the 9th century as being operated in Khorasan (Eastern Iran and Western Afghanistan).

Water turbine Wikipedia
A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work.. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical they are mostly used for electric power generation. Water turbines are mostly found in dams to generate electric power from water potential energy.

The windmills of Iran catching the storm's sting
The wind is strong as it blows across the plains of Nashtifan in Iran. It's what gave the region its oldest name 'Nish Toofan' (storm's sting). Where there's wind there's energy and the people of this region have been utilising it for centuries with horizontal windmills (that's rotation in the horizontal plane).

HISTORY OF TECHNOLOGY
The first practical windmills are constructed in or before the 9th century in a region spanning eastern Iran and western Afghanistan. They are descibed in a manuscript by Estakhri, a Persian georgrapher of that period, as having horizontal sails, like the blades of a helicopter, directly linked by a vertical shaft to the millstones turning below.

Energy conversion Windmills | Britannica
These mills, erected near what is now the Iran–Afghanistan border, had a vertical shaft with paddlelike sails radiating outward and were located in a building with diametrically opposed openings for the inlet and outlet of the wind. Each mill drove a single set of stones without gearing.

History of wind power Wikipedia
Sailboats and sailing ships have been using wind power for at least 5,500 years, [citation needed] and architects have used winddriven natural ventilation in buildings since similarly ancient times. The use of wind to provide mechanical power came somewhat later in antiquity. The Babylonian emperor Hammurabi planned to use wind power for his ambitious irrigation project in the 17th century BC.

The Watermill at Jam, Afghanistan: Preliminary Remarks
vertical shaft connecting into the lower part of the horizontal wheel mechanism, which itself consists of slightly concave paddles set at an angle to receive the full force of the water. In the upper part the vertical shaft runs through the fixed lower grindstone (3) to connect with the upper grindstone (4). The fixed

VERTICAL SHAFT WINDMILLS Earth Science
The windmills consist of a vertical ungeared shaft supported at the top. This directly turns a large stone mill wheel. A metal shaft set into the lower mill stone supports the shaft from below. The millstones are protected by a bunkerlike, thick mud brick room with a thick and tiny very solid door.

Gristmill Wikipedia
The early mills had horizontal paddle wheels, an arrangement which later became known as the "Norse wheel", as many were found in paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, causing it to grind ...
