An apparatus for converting solar and wind energy into rotational energy comprises a housing defining a lower aperture, an upper aperture and a plenum extending between the apertures. A wheel carrying a plurality of cylindrical foils is mounted within the housing for rotation about a horizontal axis. As the wheel rotates, the foils are sequentially located between the apertures. An elongated tube extends upwardly from the upper aperture to develop airflow through the plenum.

An apparatus for converting wind energy into rotational motion comprising: a housing having a lower aperture and an upper aperture; a wheel mounted for rotation within said housing and having a generally horizontal axis of rotation; about five cylindrical foil members mounted on and adjacent to the perimeter of said wheel at equal angular spacing of about 72°for rotation therewith; a semi-cylindrical cowl member for partially enclosing said cylindrical foil members and being mounted within said housing in a concentric relationship with said wheel and being dimensioned to be slightly greater in diameter than a circle defined by the outermost points of said cylindrical foil members; a cylindrical hub mounted concentrically on said wheel and being spaced radially inwardly of said foil members at a selected distance so that said hub and said cowl define a semi-annular air passageway disposed concentrically about the center of said wheel through which said foil members travel when said wheel rotates, said cylindrical hub isolating the semi-annular air passageway from space within the interior of the hub; plenum structure cooperating with said cowl member and said hub to define a plenum extending from said lower aperture to said upper aperture and being disposed so that said cylindrical foil members are disposed within said plenum as said foil members are traveling in a generally upward direction as they rotate on said wheel; an elongated tube member extending upwardly and outwardly from said upper aperture to an exhaust end, said tube member and exhaust end being configured so that wind impinging thereon causes air flow upwardly into the lower aperture, through the said plenum, through said upper aperture, through said tube member and out said exhaust end, whereby the rising air in said plenum lifts the cylindrical air foils disposed in the plenum to rotate said wheel and cause semi-circular air flow within said annular air passageway.
