Patent ID: 7665554

Claim:
In an electrically powered motor vehicle comprised of a chassis, a body, an electric motor operatively connected for propelling said vehicle, and on-board rechargeable battery means operatively connected to said electric motor for providing power thereto, and having a front end portion defining a compartment therewithin, and an underside spaced above the ground, the combination comprising: an air-flow conduit of circular cross section contained in said front end portion compartment of said vehicle, said conduit having an entrance end, proximate the front of said vehicle, and an exit end proximate said underside of said vehicle, whereby air flow is conducted by said conduit from said entrance end to said exit end during forward movement of said vehicle, said conduit comprising a first portion that extends rearwardly from said front of said vehicle on a longitudinal first axis of said vehicle, and a second portion that extends continuously from said first portion downwardly toward said underside of said vehicle generally on a second axis transverse to said first axis; a plurality of air-driven electric generators mounted in tandem and contained wholly within said first portion of said conduit and having rotor structures disposed for effective rotation, substantially on said first axis, in reaction to air passing through said first portion of said conduit from said entrance end, for generating electric current; an additional air-driven electric generator mounted and contained wholly within said second portion of said conduit, proximate said exit end, and having rotor structure disposed for effective rotation, substantially on said second axis, in reaction to air passing through said second portion of said conduit, for generating electric current; and means operatively connecting said plurality of tandem-mounted electric generators and said additional electric generator for delivering electric current for effecting recharging of said rechargeable battery means.
