Windmills: Definition, History, Types & Facts
A windmill is a device that harnesses the power of the wind by harnessing the wind's energy via the use of sails that are mounted on a revolving shaft. Both a Persian millwright in the year 644 A.D. and windmills in Seistan, Persia, in the year 915 A.D. are credited with being the first known references to windmills.

Vertical Axis Wind Turbines vs. Horizontal Axis: Which Is …
Cons of Vertical Axis Wind Turbines: Lower Efficiency: VAWTs often suffer from lower efficiency rates compared to HAWTs, mainly due to aerodynamic limitations and increased drag on the blades. Limited Scalability: Scaling up VAWTs can be challenging as the structural integrity of the turbine becomes more difficult to maintain with larger sizes.

Vertical Axis Wind Turbines
The Darrieus rotor is a type of vertical axis wind turbine (VAWT) known for its distinctive eggbeater shape. It consists of curved airfoil blades that are arranged in a vertical orientation around the central axis. Darrieus rotors are named after Georges Jean Marie Darrieus, a French engineer who patented the design in 1926.
