DETAILED DESCRIPTION

[0020] A feature of the disclosed solar collector assemblies resides in the multi-faceted solar receptors that accept solar energy both on their top surfaces and their lower surfaces; thus, increasing the area upon which solar energy strikes without consuming additional acreage. This is possible by orienting the multi-faceted solar receptors with respect to a parabolic or other designed surface that also reflects the incident solar energy to the lower surfaces of the dual faced solar receptors. Solar energy, then, strikes both the upper surface and the lower surface of the multi-faceted solar receptor assemblies. A uniqueness in design of the disclosed solar module resides additionally in making the parabolic reflector wind rotatable.

[0021] The basic components of the solar module are as follows:

A. vertical support column clad with solar receptor;
B. multi-faceted solar receptor assemblies;
C. rotating parabolic solar reflective assembly;
D. optional mesh portal for use with water filtration reservoir;
E. system display; and
F. circuitry, and battery and/or inverter components.

[0022] Referring now to FIG. 1 is a field, 10, of the disclosed solar module assemblies with rotating parabolic reflector assembly. While 9 such solar module assemblies are illustrated for field 10, the number could greater of less. The dashed arrows represent solar energy impacting field 10 while the solid arrows represent the prevailing wind experienced by field 10. The circular arrows around each solar module assembly represent the direction of rotation for each assembly caused by the prevailing wind. Energy, then, is generated by a combination of solar radiation and wind. Field 10 is mounted on a single base, 12, which may be concrete, pavement, or other material.

[0023] Referring now to FIGS. 2-5, one of the solar module assemblies, 14, in field 10 is illustrated. Segmented solar module assembly 14 includes a central solar receptor tower, 16, a rotating solar reflector assembly, 18, and a housing or base, 20, for a gear assembly (not seen). The design of rotating segmented solar reflector assembly 14 is one of choice so long as its inner surface, 22, is parabolic in shape to maximize solar reflection onto solar receptor tower 16; although alternative curvilinear or other geometric shapes likely will find use in constructing the solar module disclosed herein. Depending upon the orientation and design of solar receptor tower 16, the number of towers, and their orientation, different shaped inner surfaces may be appropriate for solar collector assembly 14. Materials of construction for solar collector assembly 12 will be appropriate for durability, resistance to weathering, and like factors, bearing in mind that solar collector assembly 12 also provides support for solar receptor tower 14. Appropriate materials, then, include, for example, metals, ceramics, glasses, plastics, combinations thereof, and the like, optionally laminated and optionally with special finishes. Regardless of material of construction, solar collector assembly 18 has a specular interior surface. In fact, the solar collector assembly even may be inflatable. Since solar collector assembly 18 is segmented, each segment has a specular inner surface and the assembly of such segments results in a curvilinear inner surface that may be parabolic in shape.

[0024] The interior surface of segmented solar collector assembly 18 will be specular so as to reflect solar radiation (dashed arrows in FIG. 1) incident thereupon. Segmented solar collector assembly 18 can be inherently specular, such as, for example, by being made from metal, such as aluminum, or can have a specular coating, 24, (see FIG. 5) applied to it. Such mirrored coating 24 is present on each segment. While such segments or panels can be horizontal or vertical in orientation and held in place by hardware (e.g., nuts and bolts), vertical such segments are illustrated in the drawings. Also, while 12 such segments, 30a-30l, are illustrated in the drawings (see FIG. 3), the number of segments or panels can be greater or lesser in number. Each segment is connected to an upper ring, 26, and to a lower cup, 28, as best seen in FIGS. 5 and 6.

[0025] With a specular lining, the structure supporting the specular lining can be made from a variety of durable materials, such as, for example, concrete, wood, metal, plastic, ceramic, combinations, and the like. Use of a specular lining may make maintenance and replacement of the specular lining, especially with for the use of segments or panels panels, easier and more cost effective. Of course, remote monitoring of the solar collector assembly or more likely an array of solar collector assemblies may find advantage.

[0026] In order for segmented solar collector assembly 18 to rotate, some type of wind interference needs to be present. In FIGS. 1-5, a curvilinear wing is affixed to each segment 30a-30l, as illustrated by wings, 32a-32l, affixed to segments 30a-30l, respectively. Of course the number of wings could be greater or lesser in number than the number of segments. Each wing is interrupts for flow of wind, which causes solar collector assembly 18 to rotate, since solar collector assembly 18 is mounted on a gear, 34, affixed to a shaft, 36, mounted within base 20, as illustrated in FIG. 5. Gear 34 in turn meshes with a geared inverter, 26, for generation of electricity. Of course, other methods for converting the generated solar and mechanical energy could be envisioned and are within the scope of the present disclosure. Referring now to FIG. 6, segments 30a-30l without wings, 32a-32l is illustrated along with cup 28 that holds the bottom of segments 30a-30l. The segments may be laterally joined by use of dovetails joints or other mechanical joining technique that desirably does not cover up too much of the inner specular surface area and does not adversely contribute to the weight of solar collector assembly 18. In this regard, the designer may want to use materials of construction that are light in weight so as to minimize the weight of solar collector assembly 18 since its rotation is desired by the designer. Incidentally, only a few of the segments are labeled in order to not obfuscate the view of the segments.

[0027] Referring now to FIG. 7, an alternative rotating solar assembly, 40, is illustrated. It will be observed that each segment now has a differently designed wing affixed to its outside, as illustrated by a wing, 42. Wing 42 is cup shaped for capturing the wind and causing solar assembly 40 to rotate for mechanically generating electricity in addition to the solar generation of electricity by solar receptor tower 16.

[0028] Since solar collector assembly 18 will be located in the sun and its interior surface will be specular or made from material providing a specular surface, it is reasonable that solar collector assembly 12 will become hot. Commonly-owned application Ser. No. 14/535,350 addresses the heat issue by proposing to use a fluid conduit(s) formed into the interior of walls forming the solar collector assembly. Running water or other fluid flowing within the fluid conduits remove excess heat. Such fluid conduits could be used in the present design at the expense of adding extra weight.

[0029] Electrical leads and electrical circuitry and connections are not illustrated in the drawings, but are to be provided in conventional fashion. Since some configurations of the disclosed solar module will have the parabolic mirror exposed to rain, provision can be made around the juncture of the central column and the mirror to place a mesh for filtering and permitting rain to flow therethrough and into a base reservoir for its collection and reuse. Of course, the disclosed solar module will have a readout display for maintenance and collection of data. Provision of an inverter, battery, and other components for collection of the generated electricity will be provided as needed.

[0030] In FIG. 8, central solar receptor towers, 44 and 46, are mounted to a base or pad, 48, much as has been described above. In this embodiment, however, a pair of projectors, 50 and 52, project holographic parabolic mirror images, 54, 56, 58 and 60, that surround central solar receptor towers 44 and 46 and reflect incident solar radiation/energy, indicated by the dashed lines, onto the solar receptive towers for generation of electricity, as has been described above. In this embodiment, rotation of the holographic reflectors is not possible or needed. The same is true for the need of cooling of the parabolic reflectors, since no cooling is needed. Of course, the number of holographic projectors could be greater or less than the number illustrated in FIG. 8.

[0031] While the device and method have been described with reference to various embodiments, those skilled in the art will understand that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope and essence of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the disclosure not be limited to the particular embodiments disclosed, but that the disclosure will include all embodiments falling within the scope of the appended claims.
