Vertical axis machine for capturing energy from wind, comprises vertical axis open drum which supports blade panels able to be continuously rotated to the most effective angle by belt or servo

摘要

A circular plate (4) rotates about a vertical axis and supports blade panels (11) with the assistance of an upper ring (34). As the circular plate rotates the blade panels also rotate to take up a most effective angle with respect to the wind. The panel rotation may be effected either by a belt drive derived from the motion of the plate or alternatively by a servo mechanism
