Developed by Victor Cheboxarov. Diameter range from 50 to 300m, with a rated power capacity from 0.5 to 50MW. The WEMU power plant is a structure with vertical blades, i.e. a wind turbine, which consists of a semi-submerged toroidal pontoon slowly rotating around the central tower. The turbine can be developed in large diameter due to the water support. The blades are actively pitch-controlled. Hydraulic transmission is used instead of a common geared drivetrain. It consists of hydrostatic water pumps and high-head water turbines coupled with electric generators. In contrast to any offshore Horizontal Axis Wind Turbine (HAWT), the WEMU turbine's origin can be traced from sailing boats which have been the best means of utilising wind energy at sea for centuries. The WEMU turbine has a vertical axis of rotation. The blades mostly use the lift (not drag) aerodynamic force. The WEMU turbine should not be confused with Darrieus turbines.
