Abstract: An improved windmill and a method for generating electricity, pumped air or rotational shaft energy are provided. A vertical mast rotatably mounts one end of a substantially horizontal and upward cantilevered support arm whose other end mounts a horizontal axis stator of dual function for both the windmill and the energy generating mechanism. A rotor is mounted co-axially to the stator, being the rotor for both the windmill blades and the energy generating mechanism. Fixed windmill blades or blades which lessen angle of attack in response to increasing wind pressure are attached to the rotor. A fan shroud in the form of a band supported by fins from the stator may encircle a disk defined by the tips of the rotating windmill blades.
