The Vertical Axis Wind Turbine Instruction. The rotor of the vertical axis wind turbine rotates around a vertical axis. The main advantage of it is that it can receive wind from any direction, so when the wind changes, the wind turbine of this kind has no need to initiate the steering device to deviate the rotor to face the wind.
Oct 31, 2014 Efficiency When the wind blows on the blades of a HAWT, all of them contribute to energy production. When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely go along for the ride. The result is comparably reduced efficiency in power generation.
