ABSTRACT:
Apparatus for deriving a rotational motion from air currents including first and second coaxial annular members spaced from each other along their axes by axial struts and a plurality of blade assemblies carried by the struts. In a preferred embodiment, the annular members are formed of circular I beams and the apparatus is supported for rotation about the axes of the annular members by rollers engaging the web of the I beams. The rollers may be carried by first and second posts with one of the posts being rotatable about the other such that the apparatus can accommodate changing wind directions. The blade assemblies may include an impeller hingedly secured to a cross-beam extending between adjacent struts with each impeller being individually spring biased to present more or less surface to the air current, dependent on its velocity. A gear train, including a roll gear secured to one of the annular members, may be employed as a power takeoff such that the derived rotational motion may be delivered to a location for use.
