The present invention relates to a roadway power generating system configured to generate power from vehicles as they pass over the power generating system. The novel system is sized and shaped to be positioned in roads. The system includes pistons positioned to be engaged by car tires. The pistons are connected to alternators. As the pistons are engaged, they turn the alternators to generate electricity. The entire system is housed in an enclosure that can be easily installed and removed.
One embodiment of the present invention is a road power generating system that includes a piston housing, a piston slideably positioned within the piston housing, wherein the piston is disposed in an extended position and is shaped to be engaged by a car tire, a crank pivotally connected to the piston and the piston housing, and an alternator connected to the crank.
The system may further include a spring positioned under the piston to dispose the piston in an extended position, the spring is sized to compress under less than 25% of the weigh of a typical car.
The system may further include a piston rod guide and a piston rod connected to and extending below the piston and slideably positioned within the piston rod guide and connected to the alternator. The piston of the system may include a rounded top that extends beyond the piston housing when the piston is in an disposed in an extended position. The piston's rounded top may also be surrounded by a non-skid surface. The piston's rounded top may be configured to extend beyond said piston housing by approximately ¾ of an inch when in an extended position.
The spring of said system may be sized to turn said alternator when returning the piston to its outwardly disposed position.
The road power generating system may be positioned within an encasement.
Another embodiment road power generator includes an encasement, a piston housing positioned within the encasement, a piston slideably positioned within the piston housing and adapted to extend beyond the piston housing and shaped to be struck by car tires, and an alternator operably connected to the piston and configured to generate electricity when the piston is depressed. The system may further include a crank connecting the piston to the alternator and designed to pivot about the piston housing.
The piston of the embodiment may be configured to extend no more than 2 inches above the piston housing. The road power generator further includes a piston rod connected to the piston and the crank and is in guided relation to a piston rod guide. The system may further include a spring positioned under the piston and sized to compress under the force exerted by a car tire. The piston may be rounded. Further, the distance between the piston housing and the piston rod is less than the distance between the piston housing and the alternator.
The system may further include a compression plate positioned below the spring, wherein the piston rod extends through the compression plate.
A further embodiment includes an encasement, a plurality of pistons slideably engaged within the encasement and extending above the encasement when not compressed, a plurality of actuators positioned within the encasement and connected to the pistons, and a non-skid surface positioned over the encasement. The pistons may be separated from each other by no more than the width of a car tire. The encasement of the system may be embedded within a road. The pistons of the system may be configured to extend no more than 2 inches above the road.
The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which in addition to the above form the subject of the claims of the invention. It should be appreciated that the conception and specific embodiments disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized that such equivalent constructions do not depart from the invention as set forth in the appended claims. The novel features which are believed to be characteristic of the invention together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures are provided for the purpose of illustration and description only and are not intended to define of the limits of the present invention.
The advantages, features, and details of the invention are explained in greater detail in the following description of the preferred embodiment, with the aid of drawings as listed below. For a more complete understanding of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawing, in which:
Upon review of the detailed description and the accompanying drawings provided herein, it will be apparent to one of ordinary skill in the art that the roadway power generating system can be used in a number of different applications. Accordingly, the present invention is not limited to the structures specifically described and illustrated herein. The disclosed systems, however, are particularly adapted for roadway power generating applications.
The system includes piston (12) positioned so that the piston head extends above encasement (11).
Pistons (12) are retained within piston housing (13). Piston housing (13) secures pistons (12) within the system (10) and more precisely constrains their movement to vertical movement. Pistons (12) are shown surrounded by bearings (14). Although bearings are shown, other means such as lubricant can be used to reduce resistance between pistons (12) and piston housing (13).
Pistons (12) are shown in an outward, extended position. They are extended by springs (15) positioned beneath each piston. Springs (15) are sized according to the load required to move alternators (20). Although single springs are shown below each piston, any number of methods can be used to extend pistons (12). For example, multiple springs, rubber bushings, compressed air, or combinations thereof can be used.
Springs (15) are braced by compression plate (21). The compression plate (21) is positioned beneath springs (15) and receives the load from springs (15). Compression plate (21) also prevents dust and other debris from entering the lower part of system (10).
Piston (12) is connected to piston rod (16). Piston rod (16) extends below piston (12), through spring (15), compression plate (21) and piston rod guide (18).
Attached to piston rod (16) is crank (19). Crank (19) is rotationally attached to piston rod hosing (13).
Encasement (11) is covered by non-skid surface (23). Non-skid surface (23) is shown with holes for pistons (12) and piston housing (13), but could be a uniform coating.
Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the invention as defined by the appended claims. Moreover, the scope of the present application is not intended to be limited to the particular embodiments of the vehicles and the methods described in the specification. Accordingly, the appended claims are intended to include within their scope such articles and/or methods.
This application claims priority to Provisional Application No. 60/704,490.
