Patent ID: 8710789

Claim:
A system for charging and/or re-charging a battery in a vehicle, comprising: a channel having a body into which wind/air can flow; a plurality of turbines located in the body of the channel, each said turbine being rotatable by the wind/air flowing through the channel; a plurality of vanes located in the body of the channel upstream of the turbines, wherein constricting locations are created between adjacent vanes, the constricting locations being located so as to increase velocity of the wind/air flowing through the channel upstream of the turbines, wherein the turbines are retractable; a computer-based control system configured to cause the each of said vanes to retract when the vehicle reaches a predetermined speed threshold associated with the vanes; and an electric power subsystem configured to harness energy generated by the turbines and charge and/or re-charge the battery in the vehicle using the harnessed energy.
