They were also Vitruvian (after the Roman engineer Vitruvius), with a vertical wheel carried on a horizontal axle. The water feeds in at the wheel's perimeter and the power is taken off through the axle. In a timber water wheel, water can get in between the …
A tower type vertical axle windmill includes a tower portion. The tower portion has a plurality of layers and a plurality of wind turbines and a computer is used to open and close the walls of the tower portion. Each of the wind turbines includes a seat portion, an energy output assembly and a rudder assembly. The seat portion can carry other components.
The water wheel is an ancient device that uses flowing or falling water to create power by means of paddles mounted around a wheel. The force of the water moves the paddles, and the consequent rotation of the wheel is transmitted to machinery via the shaft of the wheel. The first reference to a water wheel dates back to around 4000 BCE.
A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, …

There are records of vertical axis wind turbines as far back as 9th century Persia or even the 7th century BC Afghan highlands. These early VAWTs were simple devices based on aerodynamic drag; one side of the turbine was covered and the wind …
The English Medieval Windmill. Windmills abounded in England from the twelfth century onwards. Terence Paul Smith describes how their bodies usually revolved on a vertical post so that the miller could face the sails into the wind. In the earliest Middle Ages milling - where it was not done by hand using quern-stones ('blood-mills', as they ...

The horizontal-axis or vertical windmill (so called due to the plane of the movement of its sails) is a development of the 12th century, first used in northwestern Europe, in the triangle of northern France, eastern England and Flanders. It is unclear whether the vertical windmill was influenced by the introduction of the horizontal windmill to Southern Europe in the preceding century.
Hydropower, tidal power, and wind power were used to power mills and factories. Limited use was also made of fossil fuels such as petroleum. The industrial use of watermills in the Islamic world dates back to the 7th century, while horizontal-wheeled and vertical-wheeled water mills were both in widespread use since at least the 9th century.
Traditionally, wind speed is measured by anemometers – usually three cups that capture the wind rotating around a vertical axis (pictured below). The wind direction is measured with weather vanes. After measuring wind data for at least one year, the mean annual wind speed can be calculated.

How much power does a vertical wind turbine produce? There is no specific answer to this question. The output of a vertical wind turbine relies on the speed of the wind through the rotor. For example, a massive 2.5–3 MW wind turbine can produce up to six million kWh annually. It is sufficient to supply at least 1500 s with electrical ...
The European windmills of the 12th and 13th century have upright sails, of the kind still familiar today. They require simple gearing, to transmit the power to the vertical shaft which will turn the millstones. And they have to be able to turn through 360 degrees so …
The Vertical Axis Wind Turbine is a wind power generation design that puts the main rotor shaft transverse to the wind. The main components of the system are located at the base of the tower on which the vertical blades sit. This differs from the more common Horizontal Axis Wind Turbine (HAWT), where the blades attached at the horizontal rotor shaft.
The first known practical wind power plants were built in Sistan, an Eastern province of Persia (now Iran), from the 7th century. These "Panemone" were vertical axle windmills, which had long vertical drive shafts with rectangular blades.

The more powerful vertical wheels come in 2 designs: undershot and overshot. The former is a paddle wheel that turns under the impulse of water current. This technology requires gears to drive a typical millstone. When the levels of rivers fall in the dry season, and their flow diminishes, undershot wheels lose some of their power.
