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.

3. The system of claim 2, further comprising a control system configured to cause the each said vane to retract when the vehicle reaches a predetermined speed threshold associated with the vane.

4. The system of claim 1, further comprising a feature mounted to the side wall of the channel substantially in line with the plurality of vanes.

5. The system of claim 1, further comprising at least one substantially columnar feature located in the channel so as to increase velocity of the wind/air flowing through the channel upstream of the turbines.

6. The system of claim 5, wherein the at least one substantially columnar feature is located upstream of the plurality of vanes.
