Wheel based generator system
A wheel having a tire, rim and for connection to an axle, contains a hollow circumferential solenoid tube, oriented in the same plane as the wheel, around the rim, with at least one permanent magnet situated within the hollow solenoid tube. The solenoid's wires are connected to a built-in battery which can situated inside of the wheel or the vehicle to store electricity for later use. The current generated may also be connected to transfer the electricity from the wheel-generator, to an external load, via a wire or wireless means; performed while the wheel is in motion or at rest.
1. A wheel for a vehicle comprising:
a hollow closed loop circumferential tube, oriented in the plane of the wheel, and affixed to the wheel so as to rotate with the wheel;
a permanent magnet in the circumferential tube, the tube and magnet being configured so that the magnet can move within the tube;
a conductor disposed on the tube so that when the wheel is rotated, the magnet will be acted upon by gravity to reach a point along the tube so that there continues to be relative motion between the magnet and the conductor to generate an electric current in the conductor; and
electrical connections to the conductor so that current generated in the conductor is coupled to a device for receiving the electrical current.
2. The wheel of claim 1 , wherein the device for receiving the electrical current comprises an electrical storage device associated with the wheel, for storing electrical energy of the electrical current.
3. The wheel of claim 2 , where the electrical storage device is a chargeable battery mounted in the wheel.
4. The wheel of claim 1 , in combination with a mounting arrangement to rotationally mount the wheel on a vehicle, wherein the electrical connections connect the conductor to circuity of a vehicle on which the wheel is mounted.
5. The wheel of claim 1 , wherein the electrical connections connect the conductor to a storage battery in the vehicle.
6. The wheel of claim 1 , wherein the circumferential tube is evacuated of air.
7. The container of claim 1 , wherein the circumferential tube contains a lubricant for lubricating an inner surface of the circumferential tube and a surface of the magnet that comes into contact with the inner surface, to facilitate motion of the magnet along the circumferential tube, when said wheel is rotated.
8. The wheel of claim 7 , wherein the lubricant is a synthetic oil.
9. The wheel of claim 7 , wherein the lubricant has 5w-30 viscosity characteristics.
10. The wheel of claim 1 , wherein permanent magnet is a neodymium-iron-boron magnet.
11. The wheel of claim 1 , wherein permanent magnet comprises a rare earth metal.
12. The wheel of claim 1 , wherein the permanent magnet produces a magnetic field strength of at least 1.4 Tesla.
13. The wheel of claim 1 , wherein the permanent magnet is of arcuate shape to match the curvature of the circumferential tube, and is sized to allow movement of the permanent magnetic along the circumferential tube.
14. The wheel of claim 1 , wherein the conductor is wound around the circumferential tube so as to form a solenoid winding.
15. The wheel of claim 1 , wherein the electrical connections comprise inductive power transfer circuitry.
16. The wheel of claim 1 , wherein the electrical connections comprise a split ring assembly for the transfer of the electrical current.
17. The wheel of claim 1 , wherein the electrical connections comprise a commutator assembly for the transfer of the electrical current.
18. The wheel of claim 1 , wherein current is generated in the conductor when it is rotating in either a clockwise or counter-clockwise direction.
19. The wheel of claim 1 , wherein the permanent magnet remains within a lower half portion of the wheel when the wheel is rotating.
20. The wheel of claim 1 , wherein the conductor is a solenoid disposed about the circumferential tube.
