A vehicle mounted energy generator and storage system includes: a screened air inlet facing a front of the vehicle through which air enters when the vehicle is moving forward; a pneumatic barrel impeller assembly including one or more integral impeller air vanes positioned such that air flowing through the air inlet applies positive pressure to the one or more impeller air vanes to turn the pneumatic barrel impeller assembly and drive one or more generator/transmission assemblies; one or more batteries receiving energy generated by the pneumatic barrel impeller assembly; and an evacuation blower applying negative pressure to the rear of the impeller air vanes by evacuating air through one or more screened outlets not facing the front of the vehicle.

This presents a Utility Model related to an improvement introduced in a piece of equipment conceived to capture wind power generated by the displacement of trains, subways, vehicles in generaloverall trucksalong railroads, roads, etc., and to convert it in electrical power, thus using such considerable energetic potential. Considering that the assembly of one or a plurality of wind rotors (P) and respective electricity generators (G) are assembled on semi-tows (K) of the type engaged and handled by a truck (mechanical horse), considering that the trailers (K) provided with means for storing the electrical power generated, such as batteries (B), or other means for electricity transmission and storage. Thus, the aerogenerators (P) may be displaced to the points with the biggest flow of passing vehicles, and may also be positioned on the direction where the natural (predominant) winds are favorable to the best use of the wind potential.

An electricity generator includes a wind tunnel positioned on the vehicle. The wind tunnel has an open first end and an open second end. The open first end is in communication with ambient air. A turbine chamber is fluidly coupled to the open second end of the wind tunnel. At least one wind turbine is positioned in the turbine chamber. The at least one wind turbine includes a housing. A rotor is positioned in the housing along an axis that is substantially perpendicular to an axis of the wind tunnel.

Systems and methods effective to reduce a drag coefficient in a vehicle are described. A system methods may receive first air directed towards an air intake structure at a first speed. The air intake structure may transform the first air into second air of a second speed. The system may direct the second air from the air intake structure to a tunnel structure. The tunnel structure may include an entrance and an exit, where a cross-sectional area of the entrance may be less than a cross-sectional area of the exit. The tunnel structure may expand the second air into expanded air. A third speed of the expanded air may be less than the second speed of the second air. The system may create a second drag coefficient, where the second drag coefficient may be less than the first drag coefficient.

A vehicle has a plurality of turbines. Each turbine includes a housing with a spindle. Each spindle has a central axis and a rotor with outwardly extending blades. Each turbine also includes a stator positioned adjacent to an associated rotor.

A diffuser system for a vehicle comprises a diffuser component mounted on the vehicle in a position to receive airflow when the vehicle is in motion. Further, a turbine component is provided in or associated with the diffuser component. The turbine component is driven by the airflow when the vehicle is in motion.

A forced-air battery charging system for a vehicle having an engine compartment includes a turbine assembly having a casing and a plurality of blades, the casing being positioned forwardly in the engine compartment for operably receiving ambient air as the vehicle travels forwardly and having an outlet expelling the ambient air. The plurality of blades are situated in the casing between the inlet and the outlet and are operable to rotate about an axis when impacted by the received ambient air in a direction askew to the axis. An electricity generator is operatively coupled to the plurality of blades. The system includes an air duct having walls that define a channel having proximal and distal ends, the proximal end being open and in communication with the casing outlet, the distal end being open through which the ambient air exits under the vehicle after passing through the air duct proximal end.

Vehicle alternative power system is a power and generating system for an electric vehicle that allows the vehicle to self-generate power for propulsion of the vehicle eliminating the use of fossil fuel thereby improving the natural state of the environment.

Air channels and wind turbines systems are provided for cooling vehicle parts and storing electrical energy in a vehicle battery. The vehicle may have a battery, a braking system, an air duct with wind turbines and a generator. The air duct has an inlet portion for receiving an airflow, a body portion having wind turbines, and an outlet portion for directing the airflow to the braking system. A generator converts kinetic energy of the wind turbines to electrical energy stored in the battery. The wind turbines can be positioned in an air duct extending from a front bumper to an area proximal to one or more wheels to enhance vehicle aerodynamics. Alternatively, the wind turbines can be positioned in openings between grill shutters to generate energy and cool a radiator. Alternatively, the wind turbines can be positioned proximal to powertrain or drivetrain components for cooling and generating electrical energy.
