Wind turbine design Wikipedia

Wind turbines have ways of reducing torque in high winds. A wind turbine is designed to produce power over a range of wind speeds. The cut-in speed is around 34 m/s the stable atmosphere is disrupted because of friction turbulence and the atmosphere will turn neutral. A daytime atmosphere is Innovation in Wind Turbine Design.
