FIELD OF THE INVENTION
The embodiments of the present invention relate to energy concentration and collection devices, and more particularly to an energy concentration and collection device that can harness solar energy as heat or electricity.
BACKGROUND
Solar power involves methods of harnessing energy from sun light. It has become of increasing interest as environmental costs and limited supplies of other power sources, such as fossil fuels, are realized. Traditional methods of harnessing solar power involve great expensive and complicated solar cells such as photovoltaic semiconductor cells for producing electricity from solar energy. For most people, the solar cells are cost prohibitive and, therefore, impractical. Thus, there exists a need for a simple, efficient, and easy-to-use energy collection device that can be readily constructed and installed in residential or commercial settings.
SUMMARY
Accordingly, one embodiment of the present invention is an energy collection device capable of absorbing thermal energy, the energy collection device comprising a housing; a passage within the housing having a first and a second end; said passage adapted to contain a fluid, having a first heat energy, wherein the passage accepts the fluid through a first end thereof such that the fluid may absorb thermal energy within the passage and directs the fluid, having a second heat energy, through the second end of the passage. In one embodiment the energy collection device may be elevated (e.g., over a roof) or in a second embodiment the energy collection device may act as the surface (e.g., the roof).
The types of fluid that can be used include water and viscous fluids like oil, or antifreeze. As set forth in more detail below, the energy collection device can also be incorporated within an energy collection system.
In yet another embodiment, an energy concentration device includes a plurality of lenses and/or prisms about a housing for focusing the solar radiation generated during the day and at night. Ideally, the energy collection device and the energy concentration device can be used in combination. However, the devices can also be used independently.
Other variations, embodiments and features of the present invention will become evident from the following detailed description, drawings and claims.

DETAILED DESCRIPTION
It will be appreciated by those of ordinary skill in the art that the invention can be embodied in other specific forms without departing from the spirit or essential character thereof. The presently disclosed embodiments are therefore considered in all respects to be illustrative and not restrictive.
Initial reference is made to FIG. 1, which illustrates a perspective view of an energy collection device 100 elevated over a roof 102. The energy collection device 100 incorporates a tube or pipe 104 having an inlet 106 and an outlet 108 for circulating fluids such as water through the housing. The pipe 104 can also circulate viscous fluids like oil, antifreeze, or other viscous fluids capable of absorbing and transferring heat. Alternatively, the pipe 104 can circulate gaseous fluids such as xenon and argon. Although only a single pipe 104 is illustrated, there can be multiple pipes 104 and/or loops or coils of pipes 104 having multiple inlets 106 and/or outlets 108 in a pre-established or arbitrary arrangement. The pipe 104 can be fabricated of clear plastic, copper, metallic alloy, or any appropriate material for optimal thermal absorption. The use of a black-colored pipe 104 or painted pipe 104 increases the rate of heat absorption and the ability of the fluid to retain solar heat generated by the sun 101. The housing 110 may be manufactured of wood, plastic, or other materials with a high specific heat like stone, concrete, or adobe. Optionally, fiberglass and other protective materials (not shown) can be used to insulate the pipe 104. Although the housing 110 of the energy collection device 100 is shown rectangular in shape, it can take any shape as necessary to collect radiant energy from the sun 101.
As illustrated, the energy collection device 100 is elevated and maintained in position by support posts 112. The support posts 112 allow the device 100 to be positioned on a structure without having to remove roofing shingles or other composite roofing materials. The support posts 112 are metal or plastic with one end coupled to the housing 110 and the other end coupled to the roof 102. Screws and other fasteners can be used to connect the support posts 112 to the roof 102 and the housing 110. The gap or spacing created between the energy collection device 100 and the roof 102 allows the energy collection device 100 to first function as a shade or an awning for the roof 102. In other words, the energy collection device 100 not only reduces the amount of heat or sunlight exposure 101 at the rooftop surface 102, the spacing created by the support posts 112 also allows convection airflow over the roof 102 thereby dissipating heat near the rooftop surface 102.
Alternatively, the energy collection device 100 or multiple such devices can be used as roofing materials in place of shingles and other composite roofing materials. In order to do so, the housing 110 of the energy collection device 100 must be constructed of a sturdy material, such as aluminum, copper, or other metallic alloy that is strong enough to support a person's weight such that people are able to walk on the housing(s) without damaging or collapsing the same.
The basic operation of the energy collection device 100 is as follows. While elevated over the roof 102, the energy collection device 100 is exposed to the sun's energy in the form of visible and ultraviolet light. The energy collection device 100 also collects other forms of energy including but not limited to rising heat from inside the house, energy emanating from the earth's surface (not shown), and energy waves and radiant energy from celestial bodies and gravitational forces exerted thereon (not shown). The collective energy sources provide thermal energy to heat the fluid within the pipe 104. The heated fluid is circulated through the pipe 104 within the energy collection device 100. The heated fluid can then be distributed for domestic hot water use, for heating a building, or can be transferred or stored for other uses. The efficiency of the energy collection and absorption depends on various factors including the material used to fabricate the pipe 104 and housing 110, as well as any insulation that may surround the pipe 104.
Reference is now made to FIG. 2, which illustrates a perspective view of an energy collection device 100 mounted to a wall 114 on a side of a building (not shown). The energy collection device 100 can also be mounted to fences, floors, windows, awnings, patio covers, swimming pool covers, walkway covers, or any area where energy collection and/or shade is desirable. Additionally, the energy collection device 100 can be mounted to the different surfaces without support posts 112. As described above, the energy collection device 100 can be manipulated into any shape necessary to accomplish the objective of maximum energy collection and absorption, and can also be shaped (e.g., parabolic) to intentionally capture a certain spectrum of solar radiation. The energy collection device 100 can also be employed to minimize heat and energy loss by insulating buildings and vehicles, and are ideal for farms, ranches, laundromats, Indian reservations and military bases.
Reference is now made to FIG. 3, which shows a perspective view of a walkway cover 100′ elevated over a ground surface 116 and constructed of an energy collection device 100. Similarly, the energy collection device 100 can serve as patio cover elevated over a backyard cement slab 116. As illustrated, the energy collection device 100 has a pipe 104 with an inlet 106 and an outlet 108 similar to that previously described. The energy collection device 100 is maintained by support posts 112 as described above, whereby the height and size of the support posts 112 can be adjusted accordingly. In this embodiment, the support posts 112 are at least seven foot tall to allow people to walk comfortably under the walkway cover 100. Like the housing 100 shown in FIGS. 1-2, the walkway cover housing 110 can be plastic, metallic, or comprise a single-pane or double-pane glass having high ultraviolet transmittance characteristics. For a single-pane glass housing 110, the glass can be tinted or painted on both sides to increase its heat absorption efficiency. For a double-pane glass housing 110, the glass can also be tinted or painted to increase heat transfer or light absorption. Furthermore, gaseous fluids (not shown) between the double-pane glass housing 110 may be maintained in an excited state to reduce nighttime heat loss. As described above, the walkway cover 100 collects heat and energy from the sun 101 and transfer it for immediate use at the point of collection with its pipe circulation system, while also shading and blocking the amount of radiation and exposure to sunlight 101 thereunder.
FIG. 4 illustrates barrier devices 118 that can be placed at the edges of the energy collection devices 100 illustrated in previous figures. The barrier devices 118 can be made of glass, plastic, or acrylic, and function like panel sidings by insulating the areas shaded by the energy collection device 100. The barrier devices 118 can be sized to form walls for the energy collection device 100 such that the barrier devices 118 trap air and insulate the area between the energy collection device 100 and the respective roof 102, wall 114, or ground 116, thereby minimizing heat loss to the atmosphere. The subsequent increase in the roof 102 or wall 114 insulation translates into lower heating bills.
FIG. 5 illustrates an energy collection system 120 using water as the heat-carrying fluid in the energy collection device 100. As shown, a ground water supply enters the system 120 from an inlet line 122. The incoming water supply can be initially delivered to a water tank 124 in the path of the inlet line 122 as illustrated. The water tank 124 can be situated in a backyard or next to a building and colored black to increase its thermal absorption. The water within the water tank 124 is thereby pre-heated by the sun 101 and other sources of radiant or thermal energy, and may exhibit a slight rise in water temperature. The water in the water tank 124 subsequently leaves via an external mechanical pump 126. Alternatively, the water tank 124 may not be necessary and the mechanical pump 126 can pump water directly from the inlet line 122 into the inlet 106 of the energy collection device 100. Likewise, the external pump 126 may not be necessary if ground water is delivered directly from city or local municipalities, or from natural underground springs.
As previously described, the energy collection device 100 can be elevated over a roof 102 or a wall 114 of a building 128. Likewise, the energy collection device 100 can serve as a walkway cover or in other scenarios as previously described. After the water from the inlet 106 enters the pipe 104 of the energy collection device 100 and becomes heated by the sun 101 and other sources of heat in the ambient atmosphere, the heated water exits the energy collection device 100 through the outlet 108 and travels into a hot water heater (not shown) inside the building 128. Alternatively, the heated water can be converted for heating the house or commercial structure 128 using known materials and methods. Likewise, the heated water can exit the outlet 108 and be transferred to a depository 130 for future use. For example, the hot water leaving the outlet 108 can be carried to a steam boiler or hot water boiler 130 within a shed 132. The shed 132 can be constructed of cinder blocks or energy collection devices 100. As the heated water within the hot water boiler 130 continues to rise in temperature due to its confinement within the shed 132, the water may eventually reach boiling temperature and generate steam. A secondary energy source (e.g., a flame) may also be in communication with the boiler 130 to ensure the water reaches a boiling temperature. However, the energy required of the secondary energy source will be small given the high water temperature it will be working on. The generated steam can be recovered within the shed 132 and converted into electricity using known electric generators (not shown). In other words, the steam generated can be used to charge an electric generator. The converted electricity can subsequently be delivered and used in the building 128 using known methods 134.
Although the previously described energy collection devices 100 are usually external to a building, the devices can also be located within the building's interior. Likewise, although the energy collection devices 100 are situated over or above a structure, they can also be embedded within or underneath the structure. For example, in a two-story house, the energy collection device 100 can be embedded within the floorboard of the second floor thereby collecting heat circulating within the house. Likewise, the energy collection device 100 can be embedded in between the floorboards of multi-story buildings. In addition, the energy collection device 100 can be mounted in an attic underneath the roof 102, which can collect a tremendous amount of heat especially during summer. The energy collection device 100 as described can be embedded within styrofoam, sheetrock, brick, as well as any economically feasible material.
FIG. 6 shows a laundromat layout with multiple washing machines 150-1 through 150-N, dryers 155-1 through 155-N and an energy collection device 100 positioned above a furnace or broiler 160. The energy collection device 100 may be attached to the ceiling such that it hangs down over the broiler 160. The broiler 160 is responsible for providing hot water to the washing machines 150-1 through 150-N and hot air to the dryers 155-1 through 155-N. Normally, excess heat from the broiler 160 is discharged, along with heat from the dryers 155-1 through 155-N, into the atmosphere. By positioning the collection device 100 over the broiler 160, excess broiler heat rises and is absorbed by the fluid therein. The heated fluid can then be directed to the washing machines 150-1 through 150-N or used in some other practical manner. Also, as shown, the excess heat from the dryers 155-1 through 155-N is channeled via pipe 165 to the broiler 160 thereby reducing the energy load needed to operate the broiler 160. It is also possible to direct the excess dryer heat to the collection device 100 to assist in heating the fluid.
In another embodiment, the energy collection device 100 is used without the pipe 104 or fluid. That is, the shade created by the housing 110 reduces the heat temperature of the roof or wall thereby maintaining a cooler temperature within the subject structure. Indeed, a simple canvas or similar material elevated over a roof or wall with supports will reduce the roof or wall temperature thereby maintaining a cooler temperature within the structure.
FIG. 7 illustrates an energy concentration device 200 incorporating a plurality of lenses 202 about a housing 204. The housing 204 can be constructed of any suitable material and in any shape and size in order to maximize the amount of heat that can be extracted from the sun's radiation, and to focus or transfer the extracted energy to heat any fluids, metals and gases. In some instances, the energy concentration device 200 is capable of harnessing artificial radiation or the hot part of the solar spectrum at night. Ideally, the energy concentration device 200 is used in conjunction with the energy collection device 100. However, the energy concentration device 200 can be used as a standalone unit. In addition to lenses 202, other optical elements including without limitation Fresnel lenses, mirrors, glasses, prisms, plastic and polycarbonate lenses may also be used. To further focus and direct the radiation, heat and candle power elements including without limitation diffraction gratings, beamsplitters and other known optical elements (not shown) may be employed as necessary.
Like the energy collection device 100, the energy concentration device 200 can be situated in a backyard or on a house in a manner similar to that illustrated in FIG. 8. In commercial settings, the energy concentration device 200 can be situated on a rooftop of a building 208, upon an empty lot or inside a building or shed 210. The energy concentration device 200 can also be elevated over a water tank 212 situated in a backyard or next to a building 208. The building or shed 210 for housing the energy concentration device 200 can take on any shape and size to facilitate heat recovery and to protect the lenses 202. The building or shed 210 for housing the energy concentration device 200 can also be used to house steam boilers or hot water boilers. To maximize the amount of heat that can be focused by the energy concentration device 200, the building or shed 210 can be situated anywhere as required to effectively capture and distribute the solar radiation. In some instances, the building or shed 210 may be filled with inert gas to prevent fire and explosion. The energy concentration device 200, whether situated on a rooftop of a building 208, over a water tank 212, upon an empty lot or inside a building or shed 210, can be used as a standalone unit or in conjunction with the energy collection device 100.
Returning now to FIG. 7, in another embodiment, the energy concentration device 200 may include a mirror or parabolic reflector 206 to further direct and focus the solar radiation into the housing 204. The parabolic reflector 206 can be a separate unit apart from the energy concentration device 200. In another instance, the parabolic reflector 206 may be integrated with the energy concentration device 200. In operation, the parabolic reflector 206 can be mounted on top of the energy concentration device 200 and tracks the path of the sun to further improve the amount of solar radiation that can be collected during the day. The mirror or parabolic reflector 206 can further focus and concentrate the solar radiation emitted from the sun by directing the thermal energy into the energy concentration device 200. Although illustrated as a single parabolic reflector 206, there can be a plurality of parabolic reflectors 206 depending on the shape and size of the energy concentration device 200.
Although the invention has been described in detail with reference to several embodiments, additional variations and modifications exist within the scope and spirit of the invention as described and defined in the following claims.
