Abstract
A roadbed generator provides a roadbed collector positioned within a roadbed. The roadbed collector engages passing vehicles collecting kinetic energy therefrom, which is converted to electrical energy that is collected and passed to a load for use. In one embodiment a roadbed collector is a piston positioned below a hinged surface plate that forms part of the roadbed. Passing vehicles drive the plate and piston down into a cylinder containing hydraulic fluid, driving the hydraulic fluid from the cylinder to a hydraulic generator. A return spring coupled to the surface plate force the plate back into an elevated position after a vehicle has passed on. In some embodiments an expansion tank interposed between the cylinder and generator forces fluid back into the cylinder causing the piston to move upwardly in preparation for engaging another vehicle.
Description
- 1. Field of the Invention
- This invention relates generally to apparatus and methods for generating electricity and, more specifically, to apparatus and methods for generating electricity using hydraulic generators.
- 2. Background of the Invention
- The United States has over 2.4 million miles of paved roads traveled daily by millions of automobiles. Typical automobiles weigh over two tons and therefore contain large amounts of kinetic energy as they move at high speed down the highway. At the same time many auxiliary systems associated with the roadways require electrical energy to operate. For example, many lighting systems are involved, such as street lights, semaphores, warning lights, construction lights, and the like. Other auxiliary systems are services that are provided specifically to motorists, such as emergency telephones, rest areas, weigh stations, and customs inspection stations at State and international borders.
- The nation's roads extend into many remote areas. In the western United States, even highly traveled roads have long stretches extending through undeveloped areas. In such regions, it is costly and difficult to provide electrical power to provide lighting and services that may be necessary or expected. Regardless of the location of lighting systems or services, it is impossible to directly charge those who benefit therefrom. The cost of providing power to lighting systems and services must be born by the government and paid for by the public at large.
- In view of the foregoing, it would be an advancement in the art to provide a system for collecting kinetic energy from passing vehicles and convert such energy to electrical energy for use in powering auxiliary roadway systems or even the power grid of a city.
- The present invention comprises a roadbed generator for generating electricity from the kinetic energy of vehicles on a roadway. A roadbed generator provides a roadbed collector positioned within a roadbed. The roadbed collector typically mechanically collects kinetic energy from passing vehicles and transfers the kinetic energy to a generator. The generator converts the kinetic energy to electrical energy, which is then collected and passed to a load, such as a lighting system, emergency radio, or a power grid.
- In one embodiment, the roadbed collector is a piston positioned below a hinged surface plate that directly engages passing vehicles. The surface plate typically forms part of the surface of the roadbed and the hinged edge is typically maintained flush with the surface of the roadbed. A cylinder receives a portion of the piston, such that as passing vehicles drive the plate and piston down, hydraulic fluid is driven from the cylinder and through a hydraulic generator, thereby creating electricity. The electricity is then collected and passed to a load.
- In some embodiments, a return spring coupled to the surface plate forces the surface plate upward after a vehicle has passed on in preparation for engaging another vehicle. In other embodiments, an expansion tank having a spring-loaded diaphragm collects hydraulic fluid and forces the fluid back into the cylinder after a vehicle passes. Thus, the
piston 60 is forced upwardly to a position suitable for engaging another vehicle. In still other embodiments, both an expansion tank and a return spring are used to recover the surface plate and piston. - Preferred and alternative embodiments of the present invention are described in detail below with reference to the following drawings.

FIG. 9 is a process flow diagram or a method for using a roadbed collector in a sloped environment. - Referring to
FIG. 1 , in a typicalhighway environment vehicles 10 move alonglanes roadbed 20. In one embodiment of the present invention, mechanical collectors, orroadbed collectors 30, are positioned within thelanes vehicles 10. Referring toFIG. 2 , in one embodiment of aroadbed collector 30, asurface plate 40 mounts to theroadbed 20 by means of ahinge 50 and typically forms part of the surface over which thevehicles 10 drive. Thesurface plate 40 andhinge 50 are typically formed of steel and have sufficient strength to withstand the impact of vehicles at high speeds. Thehinge 50 is typically positioned such that a vehicle will first encounter the hinged edge of thesurface plate 40 and then the free end. Inasmuch as thesurface plate 40 and hinge 50 form part of the surface of theroadbed 20, thehinge 50 and hinged edge of thesurface plate 40 are typically flush with the surface of theroadbed 20. Apiston 60 is positioned below thesurface plate 40 and is depressed by thesurface plate 40 as vehicles are driven thereover. - A
cylinder 70 receiving thepiston 60 contains hydraulic fluid, or like fluid. As thepiston 60 is depressed into the cylinder, hydraulic fluid may be driven from thecylinder 70 throughhydraulic lines 80 to agenerator 90. Thegenerator 90 may derive electrical energy from the forced movement of the hydraulic fluid.Hydraulic lines 80 may then carry the hydraulic fluid back to thecylinder 70 for another iteration of the process. Areturn spring 100 may couple thesurface plate 40 to theroadbed 20 and restore the free end of thesurface plate 40 to a position elevated above theroadbed 20 ready to be depressed by another passing vehicle. Alternatively, thespring 100 may secure to thepiston 60, forcing thepiston 60 upward, which will in turn force thesurface plate 40 upward to its original position. - Referring to
FIG. 3 , thegenerators 90 may receive pressurized hydraulic fluid frommultiple roadbed collectors 30 each with acorresponding piston 60 andcylinder 70. Check valves connecting eachcylinder 70 to thegenerator 90 may ensure that backflow from onecylinder 70 to another does not occur.Electrical cables 110 may couplemultiple generators 90 to acollector 120. Thecollector 120 may modulate the voltage from thevarious generators 90 to provide a substantially constant voltage output on anoutput line 130. Aload 140 may connect to theoutput line 130 and make use of the electrical energy. Theload 140 may be the electrical power grid of a city, traffic or street lights, an emergency satellite telephone, an emergency radio, or the like. - Referring to
FIG. 4 , hydraulic fluid driven from thecylinder 70 by thepiston 60 may pass through acheck valve 200 permitting fluid flow only indirection 210 out of thecylinder 70. The fluid may then pass by anexpansion tank 220 before passing through thehydraulic generator 90. Acheck valve 250 permitting fluid flow only indirection 210 may be interposed between thehydraulic generator 90 andcylinder 70 to ensure hydraulic fluid only flows in one direction through thehydraulic generator 90. - In practice, a vehicle may quickly drive over the
surface plate 40 whereas the viscosity of the hydraulic fluid makes forcing the fluid through the generator 90 a much slower process. Accordingly, positioning theexpansion tank 220 between thecylinder 70 andgenerator 90 enables the fluid to quickly flow into theexpansion tank 220 from thecylinder 70 in response to a passing vehicle. Thediaphragm 230 andspring 240 may then force the fluid through thehydraulic generator 90 and back into thecylinder 70. In some embodiments, thespring 240 and diaphragm forcing fluid into thecylinder 70 may also serve to recover thepiston 60 andsurface plate 40, such that areturn spring 100 is not needed. - In some embodiments, a
reservoir 400 may be interposed between thecheck valve 250 and thehydraulic generator 90. Thepiston 60 may draw fluid from the reservoir 260 whereas thehydraulic generator 90 expels fluid into thereservoir 400. ThePiston 60 is typically in fluid communication with the lower portion of thereservoir 400 such that hydraulic fluid, rather than air will be drawn into thecylinder 70. - Referring to
FIG. 5 , various embodiments of theroadbed collector 30 are possible. For example, thesurface plate 40 may be dome shaped to extract energy from traffic flowing in two different directions. Thesurface plate 40,piston 60,cylinder 70 andreturn spring 100 may likewise be mounted in aramp 300 to provide a self contained unit that may be positioned wherever needed, such as at a construction project on a remote section of highway. It will be noted that theslope 310 of the ramps is only an example. Shallower slopes 310 may be used in applications where traffic is likely to be traveling at high speeds. - Referring to
FIG. 6 , in one application amethod 350 may be used in conjunction with aroadbed collector 30. Themethod 350 may include driving 360 a vehicle over a mechanical collector, such as theroadbed collector 30 described hereinabove. Driving 360 the vehicle over the mechanical collector may be an inadvertent act of the driver who happens to drive over the mechanical collector. Alternatively, driving 360 the vehicle over the mechanical collector may be intentional in order to generate electricity to operate an apparatus such as an emergency satellite telephone powered by theroadbed collector 30. - The
method 350 may also include converting 370 mechanical to electrical energy. Various conversion means are contemplated by the invention. For example, thesurface plate 40 may be mechanically coupled to permanent magnets such that depression of thesurface plate 40 causes the magnets to move through wire coils and thereby generate electricity. - The
method 350 may include collecting 380 electrical energy. The energy may be collected in a battery, high capacity capacitor, or the like. In the illustrated embodiment, collecting 380 electrical energy involves collecting energy frommultiple roadbed collectors 30, which are not all simultaneously active. Accordingly, collecting 380 electrical energy may include blending the output of thevarious roadbed collectors 30 to provide a substantially constant voltage output. - The
method 350 may include passing 390 electricity to a load, such as lighting systems or an electrical power grid. Passing 390 may take place substantially simultaneously with generation of the electricity or may be deferred. For example, the collectingstep 380 may include storing the energy to be retrieved when it is needed. For example, aroadbed collector 30 may be coupled to an emergency radio or phone that is only occasionally used. - Referring to
FIG. 7 , themethod 350 may be embodied more specifically as amethod 400. Themethod 400 may include depressing 410 asurface plate 40 andpiston 60, as by a vehicle driving thereover. Depressing 410 thepistion 60 leads to forcing 420 hydraulic fluid flow. Themethod 400 may then include generating 430 electricity from the fluid flow, such as by ahydraulic generator 90. The electrical energy may then be collected 380 and passed 390 to a load as in themethod 350 ofFIG. 6 . Themethod 400 may also include recovering 440 thepiston 60 andsurface plate 40. Recovering 440 typically includes forcing hydraulic fluid back into thecylinder 70 causing thepiston 60 andsurface plate 40 to move to their original position prior to passage of a vehicle thereover. In one embodiment, recovering 440 the piston may include moving thepiston 60 andsurface plate 40 upwardly by areturn spring 100 that is compressed when the vehicle depresses thepiston 60. As thepiston 60 moves upward, it may then draw hydraulic fluid back into thecylinder 70 in preparation for another iteration of themethod 400. - Referring to
FIG. 8 , aroadbed collector 30 may be used to convert potential gravitational energy into electrical energy. As vehicles descend hills, gravity typically powers movement of the vehicle as opposed to the vehicle's engine. Accordingly, aroadbed collector 30 may be used to harvest a portion of the kinetic energy so generated as a clean source of energy. For example, theroadbed collector 30 may be mounted in a roadbed 20 having adownward slope 500. Thesurface plate 40 may mount to the surface having itshinge 50 mounted uphill from the free end. - In some embodiments of the invention, a
lip 501 may be formed on or secured to the free end of thesurface plate 40. Thelip 501 may serve to prevent tire damage to those driving over the free end of thesurface plate 40 first, rather than the fixed end. Thelip 501 may be planar or arcuate having a radius of curvature approximating the distance between the fixed end of thesurface plate 40 and the free end. - Referring to
FIG. 9 , while still referring toFIG. 8 , as a vehicle descends the roadbed 20, aprocess 510 may occur. Theprocess 510 may include converting 520 the potential gravitational energy of the vehicle to kinetic energy as the car moves down the slope under the influence of gravity. Theprocess 510 may then include converting 530 a portion of the kinetic energy to electrical energy by depressing thesurface plate 40 andpiston 60 and causing forced hydraulic fluid flow through thehydraulic generator 90 as illustrated in theprocess 400. The electrical energy from the hydraulic generator may then be collected 380 and passed 390 to a load is in themethods FIGS. 6 and 7 . - While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the the preferred embodiment. Instead, the invention should be determined entirely to the claims that follow.
