Vehicle wheel-based power generation and display systems
A power generation system is provided configured for installation within a wheel of a vehicle. The system includes a stator having a plurality of face-mounted permanent magnets; and a rotor having a plurality of windings configured to rotate, with rotation of the wheel, in proximity to the permanent magnets thereby generating a current. The stator is mounted to a brake caliper of the vehicle. Also provided is a wheel-based vehicle display system including a light emitting diode (LED) array arranged on or within a wheel of a vehicle; a power source connected thereto; and a controller connected to the LED array. The display system is configured to display at least one of: textual information, visual images or full-motion video.
1. A power generation system configured for installation within a wheel of a vehicle, the system comprising a stator, mounted to a brake caliper of the vehicle, the stator comprising a plurality of face-mounted permanent magnets;
and a rotor having a plurality of windings configured to rotate, with rotation of the wheel, in proximity to the permanent magnets thereby generating a current, which is connected to a wheel-based automobile display system, which comprises a light emitting diode (LED) array arranged on or within the vehicle wheel; and a controller connected to the LED array, wherein the wheel comprises a plurality of spokes, which radiate from a center portion of the wheel, each spoke comprising a printed circuit board having a microcontroller and wherein the LEDs are arranged on or within the spokes, the display system is configured to display at least one of:
textual information, visual images or full-motion video.
2. The power generation system of claim 1 , wherein the stator is mounted to a bracket, which is mounted to the brake caliper of the vehicle.
