In an electric motor driven vehicle, including an electric motor adapted to provide motive power to drive said vehicle and electric storage battery means to provide electric current to said motor, an arrangement to provide electric current to the battery including: (a) fluid flow responsive impeller

In an electric motor driven vehicle, including an electric motor adapted to provide motive power to drive said vehicle and electric storage battery means to provide electric current to said motor, an arrangement to provide electric current to the battery including: (a) fluid flow responsive impeller means rotatably carried in a generally horizontal plane about a central generally vertical axis of rotation for rotation in a generally horizontal plane in response to air flow wherein said impeller means is of generally circular shape having a plurality of spaced vanes to rotate said impeller means in response to flowing air contacting said vanes; (b) generally vertical shaft means carried by said impeller means for rotation by said impeller means; (c) cage means stationary with respect to said impeller means located in spaced relation therefrom, to define a chamber to receive said impeller means, wherein said cage means includes a plurality of generally parallel spaced vertically disposed flat air directing cage louvers physically defining the exterior boundary of said cage means, where said cage louvers define air flow conduits therebetween so as to admit a multiplicity of air streams to said impeller means to rotate said impeller means where said louvers are disposed with one side to direct air flow disposed at a selected attitude relative to a tangent line of the periphery of said cage to direct air flowing therethrough to rotate said impeller means, and where a selected number of said cage louvers, lying consecutively along a portion of the periphery of said cage means are individually attitudinally disposed irrespective of ambient wind of vehicular direction, at different angles, which when measured relative to a tangent to said cage means drawn at the locus of an individual cage louver, is less than ninety degrees, and where the attitudinal disposition of a first portion of said cage louvers defining flow paths therebetween to admit a first portion of an air stream to said impeller means to rotate said impeller means in a selected direction; (d) electric generator means mechanically connected for rotation by said shaft means to generate electric current for said electric motor.
