Small scale HAWTs and VAWTs have historically all suffered from one major failing and this pertains to their ability to handle high winds or turbulent conditions. Currently there isn’t a variable pitch vertical axis wind turbine system available anywhere in the world available for general sale. The technical difficulties that need to be over come have proved too taxing even for research institutions which have no limitations in terms of time or product cost. Recent history has recorded few designs which have provided a slightly improved performance over existing fixed pitch systems; however the mechanisms used have been extremely complex and proved woefully unreliable.

Rotate on a horizontal axis generator mounted at the top. What most of us perceive as normal wind turbine that are now all around us now on wind farms.

Revolve around a vertical axis;  The main rotor shaft arranged vertically, imagine a cup spinning on pole, fixed blades.
