Abstract
Abstract A wind energy capturing device for moving vehicles including a wind turbine powered electrical power generator for installation on the roof of a moving vehicle such as a truck cab or tractor. The invention takes advantage of the powerful wind force generated by the vehicle moving on the road at moderate to high speed impinging against the wind deflector mounted on the truck cab or tractor. This otherwise “wasted” wind energy is captured and directed to the face area of the rotor blade, rotating the turbine, which, in turn, drives the generator to generate electricity. The electrical energy may be stored in a battery system and used to drive the motors of an electric vehicle or hybrid-electric vehicle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
A wind energy capturing system for moving trucks having a roofed cab comprising: a truck wind deflector mounted on the roof of said truck cab at a point forward of said wind turbine, said truck wind deflector being configured to deflect wind in a slip stream upward and over said truck cab; a wind turbine having a plurality of blades, said wind turbine being mounted to said truck cab roof; said wind turbine having an inlet located in the slip stream of said wind deflector for receiving wind deflected by said wind deflector at maximum velocity; said inlet including a turbine wind deflector projecting into the slip stream so as to deflect the maximum velocity wind into said turbine; said turbine wind deflector being located above and immediately behind said truck wind deflector so as to receive maximum velocity wind from said truck wind deflector; and an electric generator mounted on said truck and connected with said wind turbine so as to generate electricity upon the turning of said wind turbine; whereby, upon forward movement of said truck, wind deflected by said deflector enters said wind turbine inlet and turns said wind turbine, generating electric power by said generator for storage or use to operate accessories on said truck.
Claim 2
Dependent Claim
209 words
A wind energy capturing system for moving trucks having a roofed cab comprising: a truck wind deflector mounted on the roof of said truck cab at a point forward of said wind turbine, said truck wind deflector being configured to deflect wind in a slip stream upward and over said truck cab; a wind turbine having a plurality of blades, said wind turbine being mounted to said truck cab roof; said wind turbine having an inlet located in the slip stream of said wind deflector for receiving wind deflected by said wind deflector at maximum velocity; said inlet including a turbine wind deflector projecting into the slip stream so as to deflect the maximum velocity wind into said turbine; said turbine wind deflector being located above and immediately behind said truck wind deflector so as to receive maximum velocity wind from said truck wind deflector; and an electric generator mounted on said truck and connected with said wind turbine so as to generate electricity upon the turning of said wind turbine; whereby, upon forward movement of said truck, wind deflected by said deflector enters said wind turbine inlet and turns said wind turbine, generating electric power by said generator for storage or use to operate accessories on said truck.
Claim 3
Dependent Claim

Claim 6
Dependent Claim
55 words
The system of claim 1 , wherein each said wind turbine and said generator have rotating shafts, each shaft having a pulley located thereon, and a belt connected therebetween for turning said generator shaft upon rotation of said wind turbine shaft; whereby upon rotation of said wind turbine, electric power is generated by said generator.
Claim 7
Dependent Claim
15 words
The system of claim 5 , wherein said wind turbine and said generator are located
