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 solar cell assembly is provided, the configuration of which effectuates artificial tropism. The solar cell assembly may include a combination of at least one transparent solar cell and at least one opaque solar cell. The at least one transparent solar cell may transmit some wavelength(s) of incident sunlight while the at least one opaque solar cell may transmit some wavelength(s) of incident sunlight and absorbing some other wavelength(s) of incident sunlight. The transmitted wavelength(s) of incident sunlight excite or cause one or more shape-changing elements that support the at least one transparent solar cell and the at least one opaque solar cell to actuate in a manner that causes the solar cell assembly to re-orient itself towards a direction of the incident sunlight.

The disclosure is directed to an apparatus for generating energy in response to a vehicle wheel rotation. The apparatus may include a first roller comprising a curved roller surface configured to be positioned in substantial physical contact with a first wheel of the vehicle. The first roller may be configured to rotate in response to a rotation of the first wheel. The apparatus may further include a first shaft rotatably couplable to the first roller such that rotation of the first roller causes the first shaft to rotate. The apparatus may further include a first generator operably coupled to the first shaft. The generator may be configured to generate an electrical output based on the rotation of the first shaft and convey the electrical output to an energy storage device or to a motor of the vehicle that converts electrical energy to mechanical energy to rotate one or more wheels of the vehicle.

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.
