Kiwee One: an airborne wind turbine. An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism.
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
The Gansu Wind Farm Project or Jiuquan Wind Power Base is a group of large wind farms under construction in western Gansu province in China.The Gansu Wind Farm Project is located in desert areas near the city of Jiuquan in two localities of Guazhou County and also near Yumen City, in the northwest province of Gansu, which has an abundance of wind.
Roller Bearing - Brake (Semi-active system): The nacelle is mounted on a roller bearing and it is free to rotate towards any direction, but when the necessary orientation is achieved an active yaw brake arrests the nacelle. This prevents the uncontrolled vibration and reduced gyroscopic and fatigue loads.

Charles Brush's windmill of 1888, used for generating electricity. Wind power has been used as long as humans have put sails into the wind. Wind-powered machines used to grind grain and pump water — the windmill and wind pump — were developed in what is now Iran, Afghanistan, and Pakistan by the 9th century.
Wheatley Windmill, Oxfordshire. Wheatley Windmill is an 18th-century tower mill at grid reference SP 589 053 between the hamlet of Littleworth and Wheatley in Oxfordshire , England . [ 1 ] The windmill has an octagonal plan which narrows to form the circular rotating cap.
