2. Description of Related Art
The federal highway system has tens of thousands of miles of roadway stretched throughout the United States. Millions of vehicles travel these labyrinths of road each day producing emissions harmful to the environment and contributing to global warming. Each year, inclement weather and poor road conditions such as wet or icy roads cause accidents resulting in thousands of deaths and injuries. In a time of great concern for the environment, demand for reducing air pollution from vehicle emissions, increasing gas mileage, and maximizing the efficiency of the use of our dwindling land resources is at an all time high. In addition, demands are always being made for increasing the safety of the federal highway system. No system yet exists for sheltering a road while efficiently using surrounding natural resources.
In addition, it is believed that rising energy costs may someday drastically alter the way we produce and use electricity, and it may be economically viable to find new methods to collect energy for transfer into electricity. Therefore, new and improved ways to collect and use energy are being sought out. For example, there exists in the prior art a number of patents directed to wind turbines which are driven by air current created by vehicles. For instance, U.S. Pat. No. 5,272,378 to Wither; U.S. Pat. No. 6,409,467 to Gutterman; U.S. Pat. No. 7,098,553 to Wiegel et al.; U.S. Pat. No. 7,427,173 to Chen; and U.S. Pat. Nos. 7,498,684 and 7,525,210 to Fein et al. However, the efficiency and economic viability of wind turbines is highly dependent upon a constant and relatively high average wind speed to drive the vanes. Traffic ebbs and flows throughout the day depending upon the time, and it certainly slows down during the night. Thus, air current provided by traffic is not constant, and simply using air flow from vehicles to drive wind turbines is not a viable solution in many areas.
A viable solution to this problem would be a structure or other mechanical means for manipulating the air flow to increase its velocity, thereby making wind turbines an economically sound solution in many more locations.
Therefore, a need in the art exists for a structure which optimizes existing infrastructure to make the existing infrastructure more efficient, and to be optimized in a manner which will collect energy in a highly-efficient and safe manner.
In a first aspect hereof, the present invention provides a structure for sheltering and optimizing the use of a road. The structure generally comprises: (a) a structure extending over a road, having at least one way of traffic and preferably two-way traffic and a median, (b) a cover coupled to the structure, the cover enclosing and protecting the road from overhead precipitation and sunlight, and (c) a plurality of solar panels secured to said cover to convert sunlight to usable power.
In a second aspect hereof, the present invention provides a structure for sheltering a road and optimizing the collection of energy thereabout comprising: (a) a frame extending over the road; and (b) a cover secured to at least a portion of the frame; wherein the shape of the frame causes a wind current passing across the structure to be accelerated.
In a further embodiment hereof, the structure further includes a plurality of wind turbines wherein at least one of the wind turbines is located beneath the cover adjacent to at least one of a side of the road and/or the median of the road. The structure can optionally include wherein at least one of the wind turbines is positioned atop the cover at a position proximal to the peak of the structure. The plurality of wind turbines are driven by air traveling through or over the road shelter. The air flow across and about the road shelter is increased by the geometry and features of the road structure to maximize the speed of the wind driving the wind turbines. The wind turbines each have a tower, a rotor attached to the tower having a plurality of blades (or vanes), and an electrical generator.
Optionally, the structure may include an electrolytic cell, a hydrogen compressor, a hydrogen fueling station and/or compressed hydrogen storage tanks. The electrolytic cell is fluidly connected to a water storage tank to perform electrolysis on water stored in the storage tank. The hydrogen compressor is fluidly connected to the electrolytic cell to compress hydrogen gas produced by the electrolytic cell. Also provided is a compressed hydrogen fueling station, the compressed hydrogen fueling station being fluidly connected to the hydrogen compressor to receive compressed hydrogen.
The present invention may also provide an elevated rail mass transit system. As discussed in further detail below, the elevated rail can be located either within the cover and atop the road, or it can be positioned atop the cover.
In yet another embodiment hereof, there is provided a structure for sheltering and optimizing use of a road comprising: (a) a first major arch beam having an arcuate shape with a first end and a second end, each end of the major arch beam being secured to the ground on opposite sides of the road, across and perpendicular to the road; and (b) a first cross member truss including first and second ends secured to the first major arch beam proximate the first and second end of the first major arch beam respectively.
The first cross member truss is secured at a height above the road to allow clearance of traffic on the road.
A second major arch beam substantially similar to the first major arch beam and having a first end and a second end, the second major arch beam is secured substantially similar to and parallel to the first major arch beam.
The structure, also, has a second cross member truss including first and second ends secured to the second major arch beam proximate the first and second end of the second major arch beam respectively. The second cross member truss is secured at a height substantially similar to the first cross member truss.
A first support beam is secured between the first and second major arch beams adjacent to a first edge of the road. The first support beam extends parallel to the first edge of the road. A second support beam is secured between the first and second major arch beam adjacent to a second edge of the road opposite the first support beam. The second support beam extends parallel to the second edge of the road. A plurality of arcuate support beams forming a rib like structure between the first and second major arch beam and having first ends is secured to the first support beam and second ends secured to the second support beam. A cover extends between the first and second major arch beams and over the plurality of support beams to form a roof-like structure over the road. According to this embodiment, a plurality of solar panels are secured to the cover to convert sunlight to usable power.
The present invention can further comprise a method for sheltering and optimizing the use of a road comprising: (a) covering a road with an enclosed structure spanning over the road; (b) coupling a solar panel to the structure to convert sunlight to usable power; (c) coupling a wind turbine to the structure to convert wind energy to usable power; and (d) providing a vertical wind turbine within the structure to collect energy and redirect the flow of air exiting the vertical wind turbine with the flow of traffic on the road to decrease air resistance against the traffic.
Critical to the design of the road shelter is that the velocity of the air current increases substantially as it flows over, across, and through the road shelter, thereby maximizing the energy drawn from the air by the wind turbines. As air approaches the road shelter from the side, the arcuate shape of the road shelter forces the air upward, and the air accelerates much like the design of an airplane wing. The accelerated air is then redirected toward and through wind turbines to capitalize on the increased wind speeds.
It is believed that wind turbines are not otherwise suitable for use in areas that do not have a sufficient average constant wind velocity to make the wind turbines an economically viable solution. However, the road shelter's inherent design can increase the ambient wind speed by 20% or more, thereby making wind turbines a realistic solution for many more locations than was previously known. In addition, the efficiency of a wind turbine increases exponentially as the wind speed increases. Therefore, the design of the road shelter creates an increase in wind speed which it is able to collect and maximize.
For a more complete understanding of the present invention, reference is made to the following detailed description and accompanying drawings. In the drawings, like reference characters refer to like parts throughout the views in which:
As noted above, the present invention is directed to a structure for sheltering a road and optimizing the amount of energy collected thereabout for transfer into electricity or other usable fuel-sources. The structure includes a structural support frame constructed over a roadway, a cover over a portion of the structural support to shelter the roadway from the elements, and a plurality of solar panels. The solar panels are installed on the cover and connected to an electrical network.
In a second embodiment, at least one vertical wind turbine is located in a median of the road and secured to portions of the structural support beams. At least one horizontal turbine can also be provided which extends above the cover, and which is driven by air current flowing over the cover.
In a third embodiment, an electrolytic cell is provided which performs electrolysis of water stored in a water storage tank filled by a drainage system which collects rain water running off of the cover.
In a fourth embodiment, an elevated rail is located near the cover on either the inside or outside of the structure.
It is to be appreciated by one having ordinary skill in the art that the described road shelter may be one of multiple identical “grid pieces” that can be connected in sequence to create a road shelter stretching many miles.
The following description of the preferred embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
With reference to
In this exemplary embodiment of the present invention, the structural frame 12 includes spaced apart major arch beams 28 and 30, cross member trusses 32 and 34, arch support members 36 and 38, a plurality of support beams each denoted at 40, and foundations 42. The structure 12 may be made from any suitable building material, for example, structural steel, concrete, or like. The major arch beams 28, 30 can comprise a pair of arcuate I-beams having ends 28a, 28b and 30a, 30b, respectively. The major arch beams 28, 30 extend perpendicular to and over the road 20 and are stabilized at the ends 28a, 28b, 30a and 30b by the foundations 42 located adjacent to the road edges 24, 26. Preferably the major arch beams 28, 30 extend upwardly from the foundations 42 at an angle of about 70°-80° with respect to the horizontal plane.
The major arch beams 28, 30 are oriented substantially parallel to one another and are preferably spaced approximately 100 feet apart. However, the spacing may be adjusted depending on road curvature or other design parameters. The cross member truss 32 includes ends 44 and 46 coupled to the major arch beam 28 in a customary fashion at a height of approximately 20 feet such that the cross member truss 32 is in-plane with the major arch beam 28 and extends across and perpendicular to the road 20. Alternatively, the cross member truss 32 may be coupled to the major arch beam 28 at any desired height to allow clearance of vehicles with various heights on the road 20 by at least about 20 foot thereabove. Much like the cross member truss 32, the cross member truss 34 includes ends 48 and 50 coupled to the major arch beam 30 as the cross beam 28 to the arch beam 28.
The arch support member 36 includes ends 52 and 54. End 52 is coupled to the major arch beam 28 in a conventional manner and end 54 is coupled to the major arch beam 30 in a similar manner. The arch support member 36 is at a height of approximately 30 feet above the road 20 and is oriented substantially parallel to the road edge 24. Alternatively, the arch support member 36 may be coupled to the major arch beams 28, 30 at a different height to vary the amount of surroundings visible to drivers on the road 20. The arch support member 38 includes ends 56 and 58. The end 56 is coupled to the major arch beam 28 and the end 58 is coupled to the major arch beam 30 in a fashion similar to the arch support member 36 on the opposite side of the road 20, such that the arch support member 38 is oriented parallel to the road edge 26.
The plurality of support beams 40 may be arcuate I-beams or trusses smaller in size than the major arch beams 28, 30 and having ends 60 and 62. The end 60 is coupled to the arch support member 36 and the end 62 is coupled to the arch support member 38 in a conventional manner such that the support beam 40 extends perpendicular to and over the road 20. The support beams 40 may be placed evenly between the major arch beams 28, 30 to form a rib-like structure, for example every 20 feet. However, the placement of the support beams 40 may vary depending on structural need and geographic location.
Optionally, at least one platform 41 can be provided which is disposed between the successive support beams 40. Preferably, each provided platform 41 is 4 feet in width, and five adjacent platforms 41,41′, etc. are provided to span between each adjacent set of support beams 40. Each of the platforms 41 can be configured for use as desired. For example, at least one of the platforms 41 can comprise a tank or vat (not shown) for storing rain water which has run off the cover 14. At least one of the platforms 41 can also comprise a location for storing batteries (not shown) which are being (or have been) charged in a manner described in further detail below. At least one of the platforms 41 can also comprise a duct 43 for receiving accelerated exterior air and delivering the accelerated air to a respective vertical wind turbine 106. In one arrangement, a successive series of the platforms 41 can be configured to rotate between a tank, battery location, duct 43 and so forth.
As shown in
For any platforms 41 which comprise a duct 43, the extended duct 43 provides a collection point 45 for accelerated exterior air, such as shown in
The cover 14 may be any suitable material for enclosing the structure 12, such as sheet metal, glass, or the like. The cover 14 is secured to the plurality of support beams 40 by any conventional means well-known to one having ordinary skill in the art and extends from the major arch beam 28 to the major arch beam 30 and from the arch support member 36 to the arch support member 38 to create a roof-like enclosure over the rib-like structure formed by the support beams 40. The cover 14 shields the road 20 from environmental elements like rain, snow and sun, thus allowing for safer driving conditions and the ability to expedite road construction even in bad weather.
Referring now to
In one embodiment in
The cover 14 may also include a plurality of photovoltaic cell solar panels 88. As solar panels are well known in the art, discussion of their technical structure is not needed. Any suitable type of commercially available photovoltaic cell solar panel can be used for use herewith. The solar panels 88 may be rectangular and approximately 4 feet long, 2 feet wide and oriented lengthwise across the cover 14 as shown in
In a second preferred embodiment and with reference to
The blades 104 of the wind turbine 16 convert wind energy to kinetic energy as is well-known in the art. While a three-bladed horizontal wind turbine is illustrated, any suitable wind turbine may be used. The rotating kinetic energy of the blades 104 and rotor assembly 102 is then transferred to electrical energy by the generator. The electricity produced by the wind turbine 16 is then stored in batteries (not shown) for later use, connected to a power grid, used to power particular structures within the road shelter 10 itself, and so forth.
With reference to
Each rotor shaft 108 is rotated by the blades 110 in a counter-clockwise direction. Preferably the blades 110 are shaped and oriented so that the air exiting the vertical wind turbines 106 is in the direction of travel of the vehicles using the road 20, thus reducing air resistance against the vehicles. As described above, accelerated air entering the vertical wind turbines 106 can be delivered by a respective duct 43. The wind current generated by the vertical wind turbines 106 will reduce vehicle fuel consumption and vehicle emissions that are harmful to the environment. The rotor shaft 108 and the blades 110 can also be connected to a generator (not shown) for converting wind energy into electrical energy.
Additionally, the vertical wind turbines 106 may further include at least one exhaust deflection wall 112. Each of the exhaust deflection walls 112 can be located in diagonally opposite quadrants to block the air exiting the turbines 106 from being directed towards the oncoming traffic. The curvature of the exhaust deflection walls 112 is complimentary to the rotational path of the vertical wind turbines 106 and assists the vertical wind turbines 106 in directing air current in the direction the traffic is traveling. The air current generated by the vertical wind turbines 106 hitting the exhaust deflection walls 112 will be directed around the curvature in a counter-clockwise direction and in the direction of the flow of traffic on respective sides of the road 20.
In a third embodiment, an electrolytic cell 200 can optionally be provided. When provided, the electrolytic cell 200 is preferably located near the water storage tank 87 or any tank located on the platform 41, as illustrated in
The hydrogen gas resulting from the electrolysis may then be compressed by a hydrogen compressor 202 and transferred by pipe to a hydrogen storage tank (not shown) or a compressed hydrogen fuel station 204 located within the road shelter 10 for refueling vehicles. The compressed hydrogen may also be sent to offsite locations.
In a fourth embodiment, the road shelter 10 can also optionally include an elevated rail transportation system 18 as depicted in
As shown in
Optionally, the road shelter 10 can comprise an elevated platform 120 which includes an overhang 122. It is understood by one having ordinary skill in the art that the elevated platform 120 has particular utility when the elevated rail 18 is positioned atop the cover 14. Solar panels 88 can be placed atop the overhang 122. The overhang 122 also provides a shelter to the railcar 306. As shown in
As shown in
The road shelter 10 described above may be one grid section of a much larger road shelter comprised of identical grid sections connected to one another along a stretch of highway. One or more features described above may be excluded or altered in specific grid sections due to, for example, transportation demands, building requirements and geographic location.
The road shelter 10 can be suitable for use with the intersection of roads as well.
It is known to those having ordinary skill in the art that vertical wind turbines can be subjected to deflection about their vertical axis from high wind speeds, and this deflection causes a decrease in efficiency. Thus, it is advantageous to provide vertical wind turbines which are rotatably mounted at both the top and bottom to substantially eliminate deflection, as is provided for in the exemplary embodiments of the present invention.
It is understood by one having ordinary skill in the art that a “horizontal” turbine is one which generally includes a rotating horizontal axis, and a “vertical” turbine is one which generally includes a rotating vertical axis. The present invention is not intended to be so limited by the disclosure of any particular turbine being either horizontal or vertical. It is intended that any suitable turbine known to one having ordinary skill in the art can be used as described generally above.
It is appreciated by one having ordinary skill in the art that the road shelter can be connected to a power grid to allow the road shelter to provide temporary electricity to surrounding residential and commercial areas during power outages. In this respect, the road shelter can provide near-instantaneous electricity generated by the solar panels and the various wind turbines which is advantageous over many traditional power sources (e.g., coal plants, nuclear power plants, etc.) which can take days to “turn on” and ramp up to full capacity.
It is also appreciated by one having ordinary skill in the art that the present invention described herein provides flexible and adaptive solutions. The road shelter can be modified or outfitted with various implements described above as desired. For instance, the vertical wind turbines can be omitted when the road shelter is located in close proximity to residential or commercial areas. Furthermore, the road shelter uses turbines, solar panels, and other commercially available products to allow older components to be swapped out with newer more efficient products as they become available, thereby continuously improving the efficiency of the road shelter. Therefore, the present invention provides an energy efficient invention which is optimized geographically for use in solving modern day energy problems.
Furthermore, the foregoing discussion discloses and describes merely exemplary embodiments of the present invention. One skilled in the art will recognize from the discussion, and from the accompanying drawings and claims, that various changes, modifications and variations may be made therein without departing from the spirit and scope of the invention as defined in the following claims.
This application claims the benefit of U.S. Provisional Application 61/262,398 which was filed on Nov. 18, 2009, the entire disclosure of which is hereby incorporated by reference, including all drawings and formal papers.
