Abstract
The revolving overhead windmill includes airfoils that harvest wind energy using a configuration, in the class of vertical axis wind turbines, wherein the airfoils are modestly elevated above a water or ground surface through the use of buoyancy forces and elongated structural members. The airfoil angle of attack is controlled in a periodic manner as each airfoil revolves around a closed circuit of revolution, in order to optimize system energy harvest as measured by metrics such as megawatts of electric power generation under rated wind conditions. Typical large-scale applications in high wind, offshore locations can substantively contribute to utility-scale renewable energy production and also contribute towards climate change mitigation targets.
