Patent ID: 8710691

Claim:
A wind-driven electricity generating system for a vehicle, said vehicle having a body and a back section and being at least partially electrically-powered by a battery mounted in said vehicle, the system comprising: a) an air intake unit having a plurality of inner walls forming airflow channel comprising an air scoop forming an inlet opening, and an air exhaust forming an outlet opening; b) turbine, being rotatable perpendicular to the vehicle direction of motion, said turbine positioned in airflow communication with said air outlet opening; and c) an electric generator operatively coupled with said turbine, wherein said air intake unit is sealingly attached to an external surface of said body of said vehicle; wherein said air scoop faces the forward moving direction of said vehicle; wherein the airflow channel is positioned in airflow communication with said inlet opening; and wherein said electric generator is operatively connected to said battery of said vehicle thereby at least partially recharging said battery, said vehicle being in forward motion; and wherein said airflow channel is disposed only on a roof ( 60 ) of the vehicle, thereby said airflow channel substantially is not curved, and thereby said turbine ( 120 ) being positioned in airflow communication with said air outlet opening ( 114 ) is disposed substantially adjacent and below the roof, thereby diminishing length of said airflow channel; and wherein a length of said turbine ( 120 ) is larger than a length of said air outlet opening ( 114 ), and occupying at least 70% of a width of said vehicle at said turbine location, thereby enlarging a cross-sectional area of said airflow channel, thereby improving air flow supplied to said turbine.
