Vehicle actuated, roadway electrical generator
First Claim
1. A system for generating electricity in cooperation with a roadway having a vehicle-passage surface adapted for contact traversal by wheeled vehicles, this system comprising:
- (a) means transversely and interceptingly disposed in said vehicle-passage surface in a manner which permits activational rollover by the wheels of traversing vehicles;
(b) a spindle operatively associated with said transverse-intercept means and configured for axially-reciprocating motion activated upon said intercept means being encountered by said traversing wheels; and
(c) rotor-and-stator means for generating electricity, said generator being disposed with its rotor coaxially surrounding a portion of said reciprocable spindle;
with(d) said spindle having screw-thread means carried on its periphery; and
with(e) said rotor having yoke means carried on its spindle-surrounding interior, said yoke means being adapted to be matingly rotated by said screw-thread means when said spindle is axially reciprocated through said yoke.

Abstract
The present invention transforms the vast amount of existent vehicular travel into an equally-vast alternative energy resource employable for the generation of electricity. This transformation is achieved by means of a novel system which generally includes a momentum-conversion assembly configured to convert available vehicle momentum into operational momentum for an associated momentum-referenced electricity generator. The conversion assembly is accordingly structured to be responsive to the passage along an associated roadway of vehicles having predeterminable roadway-traversal momentum, with a portion of this momentum then being that which is cooperatively applied to the generator. The resulting double utilization of associated energy resources for both vehicle motion and electricity generation constitutes an effective increase in resource conversion efficiency.
In a convenient specific embodiment, the generator is of the rotor-and-stator variety and the conversion assembly is companionably configured to convert a given vehicular-momentum portion into rotational momentum for the associated rotor. For an embodiment of this nature, the conversion may then be more-specifically achieved by the particular means of an externally-threaded spindle mechanized to axially reciprocate through a matingly-rotated yoke carried on the interior of the rotor. The reciprocations of the spindle, and hence the rotations of the rotor, are induced by overpassing vehicles encountering a spindle-end which is interceptingly disposed in the vehicle roadway.
The invention yet-more-specifically provides that the subject system may be realized in a modular form entailing a plurality of readily-replaceable and conveniently-transported foldable roadway sections.

9. A system for generating electricity comprising:
-
(a) a plurality of generator modules which in operational ensemble form a portion of a vehicular roadway having a vehicle-passage surface adapted for contact traversal by wheeled vehicles;
each of said modules including;(b) means, transversely disposed with respect to the vehicular roadway, for intercepting the vehicle passage surface in a manner which permits activational roll-over by the wheels of traversing vehicles; (c) a spindle which with respect to said vehicle-passage surface is transversely juxtaposed on the surface side which is opposite from the side along which vehicles traverse; (1) said spindle being both operatively associated with said transverse-intercepting means and configured for axially-reciprocating motion and activated by the wheels of traversing vehicles; and (2) said spindle having spiral screw-thread means carried on said spindle'"'"'s axial periphery; (d) spring means for returning said spindle and the associated surface-intercepting means to their unactivated positions after the passage of an activating vehicle wheel; (e) rotor-and-stator means for generating electricity, said generating means being disposed with its rotor coaxially surrounding a portion of said spindle, said rotor carrying yoke means on its spindle-surrounding interior; and (f) said yoke means being adapted to be matingly rotated by said screw-thread means when said spindle is axially reciprocated through said yoke, said yoke including means for unidirectionally driving said rotor in response to the bi-directional reciprocations of said spindle. - View Dependent Claims (10, 11)
