  • WIND-WORKS: Vertical Axis Wind Turbines

    Vertical axis wind turbines aren't replacing horizontal axis offshore turbines February 18, 2014, by Mike Barnard. Over the past few months, an interesting wrinkle on the vertical-axis-wind-turbines-are-better mythology has surfaced: that they are superior offshore and that many countries are investing heavily in...

  • Vertical Axis Wind Turbine - InDepthInfo

    A vertical axis wind turbine (VAWT) has a shaft that spins vertical to the ground. Because of its orientation, the turbine never needs to be reoriented to face the wind. This generally means that it requires fewer moving parts and safety devices than the horizontal axis wind turbine (HAWT).

  • Horizontal Vs. Vertical Wind Turbines | Education - Seattle PI

    Wind turbines have two main design categories: horizontal and vertical axis. The horizontal-axis turbine typically has a three-blade vertical propeller that catches the wind face-on. The vertical turbine has a set of blades that spins around a vertical axis. Each type has .
