A solar collector includes a roller rotatably attached to a vehicle. A carrier fabric panel is attached on one end to the roller. Side guides are attached the sides of the carrier fabric panel. Solar cells are connected in series and are attached to the carrier fabric panel. The solar cells are connected to an electrical power storage system. Electrical leads are attached to the carrier fabric and electrically coupled to the solar cells. Electrical conductors are attached to the carrier fabric between the solar cells and the right and left guides or are provided with retainer strips. A slip ring connector is disposed on the roller for electrically coupling the electrical conductors to an electrical power storage system. The solar energy collected may be used to power actuatable accessories or passive systems that may draw power when the vehicle is not being operated.

A wind turbine panel is configured to distribute electricity to a load. The wind turbine panel includes a frame further comprising a first slot having a first slot first end and a first slot second end. A first alternator is located in a first alternator mount on the first slot first end. A second alternator is located in a second alternator mount on the first slot second end. A wind turbine is connected to the first alternator and the second alternator via a first alternator shaft and a second alternator shaft, respectively. The first alternator and the second alternator are electrically coupled to an electrical outlet point on the frame. Wind traveling through the frame rotates the wind turbine, impels the alternator shafts to generate electricity which is then transferred to an electrical outlet point and further to an electrical panel for use in a plurality of downstream applications.

The invention provides an alternative electrical charging system for a vehicle which is at least partially powered by electricity. The system employs a wind driven generator which produces electricity in response to air motion. When the generator is operating, electricity is communicated the battery of the vehicle. Operation of the generator involves a controller that monitors the electrical status of the battery and selectively activates a fan or opens a ducting system communicating with the generator. The controller also, in some embodiments, monitors the motion and the attitude of the vehicle.

An air-guiding device which is arranged in a top rear region of a vehicle and includes an air-guiding element which is shiftable from a retracted inoperative position to an extended operating position, wherein, in both positions, the air-guiding element serves for guiding air in the rear region of the motor vehicle. At least one propeller of the air-guiding device which, together with the air-guiding element, is shiftable between the retracted and extended positions, wherein the propeller, in the extended operating position, is fixable in a first operating state, wherein the at least one propeller, in the extended operating position, is operable in a second operating state in order to produce a throughflow in the direction of travel, and wherein the at least one propeller, in the extended operating position, is operable in a third operating state in order to produce a throughflow opposed to the direction of travel.

An energy-producing system comprising an axle configured to be driven by an electric vehicle's wheels when in motion. The axle supports a series of wind-catching cups contained within an aerodynamic housing configured to direct air to the cups while also increasing the air speed. During vehicle motion, the cups are acted upon by rushing air causing the rotation of the axle such that the rotation may be transferred into energy via a generator/alternator linked thereto. A series of similarly polarized magnets integrated on said cups and/or spacers and/or housing proximate thereto further maintain the axle in motion during short vehicle stops. The system extends the life of the batteries between charges as well the distance the vehicle can travel between charges. A bracket supporting a series of permanent magnets assists with driving the axle.

A fluid dynamic kinetic energy-based frictionless type generator of a range extender and recharger for an electric vehicle or device and the production of electricity is characterized by converting fluid motion into electric energy. This device uses the drag force acting opposite to the relative motion of objects moving with respect to a surrounding fluid. This force can exist between two fluid layers or a fluid and a solid surface. The device comprises a cylinder covered with paddles, air ducting ramp, permanent magnets, armature winding, charge controller and battery bank. It's a frictionless, high efficiency, brushless generator design that utilizes kinetic energy produced by drag, pressure, friction, fluid resistance, fluid dynamics, aerodynamics, wind, and or motion together with the device itself to create a frictionless brushless generator that will deliver power to the engine directly, the enclosed battery bank or can be diverted to the vehicle battery bank for recharging.
