Systems and/or methods for using air/wind power to charge/re-charge vehicle batteries
First Claim
1. 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; 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.

Abstract
Certain example embodiments of this invention relate to techniques that harness air/wind power to charge and/or re-charge a battery of a vehicle that is at least partially electrically powered. In certain example embodiments, air/wind enters into a channel formed in a vehicle and turns a turbine which, in turn, generates electricity that may be used to charge and/or re-charge a battery of the vehicle. In certain example embodiments, the velocity of the air/wind may be increased within the channel by virtue of features including, for example, retractable and/or directional vanes and/or side wall elements that help create constricting locations (or choke points). In certain example embodiments, the velocity of the air/wind may be increased within the channel by virtue of features that produce the Coanda effect. Thus, for instance, both the Venturi effect and the Coanda effect may be used to increase the efficiency of the overall system.
