    [0004] FIELD OF THE INVENTION
    [0005] The present invention relates to structures and methods for growing crops (or producing valuable chemical and / or biological compounds and / or materials of interest) and capturing solar energy.
    [0006] EXHIBITION OF THE BACKGROUND
    [0007] The production of greenhouse crops represents a significant and growing part of agriculture, especially for special crops and certain plants. The area dedicated to the cultivation of greenhouse vegetables worldwide is estimated at 473,466 hectares (+ 14 % in 2015). However, conventional greenhouses are energy intensive and expensive to light, heat, or cool. Energy forms a substantial fraction of total production costs (15-30%) in at least some conventional greenhouses.
    [0008] So-called "smart greenhouses" can also capture solar energy to generate electricity without necessarily reducing plants' ability to grow. For example, scientists at the University of California, Santa Cruz (UCSC) have shown that crops such as tomatoes and cucumbers can grow relatively normally in such solar-powered "smart" greenhouses that capture solar energy to generate electricity.
    [0009] Bright magenta panels cover the top of UCSC's "smart" greenhouses, absorbing sunlight for a long wave or specific wavelength band and transferring the energy to photovoltaic strips. Photovoltaic strips produce electricity. Greenhouses are capable of taking a certain portion of sunlight as energy and leaving the rest, allowing plants to grow using a technology known as a wavelength selective photovoltaic (WSPV) system. The technology can be less expensive and more efficient than traditional photovoltaic systems.
    [0010] It has been reported that 20 varieties of tomatoes, cucumbers, lemons, limes, bell peppers, strawberries, and basil were tested for growth and fruit production at two or three locations in California. 80 % of the plants were unaffected by the slightly darker lighting from the magenta panels, but 20% of the crops grew better. The tomato plants needed 5% less water under the magenta panels.
    [0011] This "Background Statement" section is provided as background information only. Statements in this "Background Statement" are not an admission that the object disclosed in this "Background Statement" section constitutes prior art. to this disclosure, and no part of this "Background Statement" section may be used as an admission that any part of this application, including this "Background Statement" section, constitutes prior art to this divulgation.
    [0012] SUMMARY OF THE INVENTION
    [0013] The present invention relates to structures (for example, buildings or other enclosures) adapted to produce multiple "crops", continuously and / or intermittently for a predetermined period of time (for example, a calendar year or other period of time comprising multiple seasons culture). Crops generally include food crops or plants from which valuable materials (such as certain biological compounds and other chemicals), electricity and potable water can be obtained. During the growing season, multiple food plants, or other biological crops, can be grown in the same space within the structure. Therefore, in some embodiments, the present invention relates to a fully productive greenhouse, configured to produce solar energy. For example, sunlight in the green wavelength band can be captured by a solar concentrator, and light in the red and blue wavelength bands can be used for greenhouse crop production. The light captured by the solar concentrator can produce electrical energy, which can be used in the greenhouse or sold for income. Revenues can, in turn, finance greenhouse production. Therefore, the present invention increases climate resilience.

The solar energy concentrator comprises one or more absorbers or fluorophores selected from phycobiliproteins, fucoxanthins, and luminescent molecules and materials. Luminescent materials and molecules can be inorganic. The energy conversion device is configured to receive and convert the light emitted and / or collected by the solar energy concentrator into electrical or thermal energy.
    [0015] The structure may be characterized in that the energy conversion device comprises a plurality of photovoltaic (PV) cells configured to receive the light emitted or collected by the solar energy concentrator, and / or the solar energy concentrator absorbs the first length of wave or wavelength band of light and emits a third wavelength or wavelength band of light that has longer wavelengths than the first wavelength or wavelength band of light. For example, the third wavelength or wavelength band may have a minimum wavelength greater than the maximum wavelength of the first wavelength or wavelength band. The third wavelength or wavelength band may be different from the second wavelength or wavelength band.
    [0016] The structure can be further characterized in that the energy conversion device receives the light emitted by the solar energy concentrator and converts the received light into electrical energy.

Likewise, the solar energy concentrator may have a main surface (i) facing the roof, (ii) parallel to the roof, or (iii) orthogonal or substantially orthogonal to sunlight for at least part of the day (for example, the solar energy concentrator can be configured to "follow the sun"). The structure can be further characterized in that the energy conversion device surrounds one or more, two or more, or substantially all of the peripheral edges of the solar energy concentrator.
    [0017] The structure may be characterized in that the one or more supports or surfaces are configured to allow the algae to receive the second wavelength or wavelength band of light. Alternatively, the structure can be characterized in that the support (s) or surfaces can be configured to support one or more water tanks, and the one or more water tanks can be configured to grow photosynthetic plants and / or algae in water. For example, plants can photosynthesize using photosystem II (PS2) or water-plastoquinone oxidoreductase.

Therefore, for example, the phycobiliprotein (s) and / or organic fluorophores can be tolerant (for example, to thermal energy) at a temperature of up to 40 ° C, 50 ° C, 60 ° C, 70 ° C, 80 ° C, 100 ° C, or more. Additionally or alternatively, the framework may further comprise a photoabsorbent material that protects the phycobiliprotein or fluorophore and / or increases the molecular stability of the phycobiliprotein or fluorophore in an environment containing ultraviolet or blue lights.

The condenser may comprise a conduit or container that includes or is in communication with a cold water source. The structure may further be configured to irrigate the plants and / or algae with the condensed fresh water.

    [0042] DETAILED DESCRIPTION
    [0043] Reference will now be made in detail to various embodiments of the invention, examples of which are illustrated in the accompanying drawings. Although the invention will be described in conjunction with the following embodiments, it will be understood that the descriptions are not intended to limit the invention to these embodiments. Rather, the invention is intended to cover alternatives, modifications, and equivalents that may be included within the spirit and scope of the invention. Also, in the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to unnecessarily complicate aspects of the present invention. Likewise, it should be understood that the possible permutations and combinations described herein are not intended to limit the invention. Specifically, variations that are not inconsistent can be mixed and matched as desired.
    [0044] For convenience and simplicity, the terms "part", "portion", and "region" may be used interchangeably, but these terms generally receive their art-recognized meanings. Furthermore, unless otherwise indicated in the context of its use herein, the terms "known", "fixed", "given", "true" and "predetermined" generally refer to a value. , a quantity, a parameter, a constraint, a condition, a state, a process, a procedure, a method, a practice, or a combination thereof that is, in theory, variable, but is usually set in advance and not it is later modified when in use.
    [0045] FIG. 1 depicts an exemplary greenhouse 100 adapted for quadruple harvesting in accordance with one or more embodiments of the present invention. The expression "quadruple harvest" refers to the ability to grow crops for three seasons in a year (for example, a period of time of 12 consecutive months), in addition to capturing energy solar during that period. Alternatively, Quadruple Harvest can refer to the ability to grow crops for two seasons in one year, in addition to capturing solar energy and producing fresh water during that period. The term "fivefold harvest" can refer to the ability to grow crops for three seasons in a year, in addition to capturing solar energy and producing fresh water during that period. A greenhouse or other structure capable of multiplying crops by four or five can produce at least twice the income per acre relative to most farms in the world, using 10 times less water. Therefore, the production of crops is less expensive and farmers' sources of income can be expanded (for example, to additional crops and / or by selling surplus electricity and / or water).
    [0046] Frame 100 includes roof panels 110, walls 140, front panel 130, rear panel (not shown), one or more doors 135, and optional front and rear gables 120. Roof panels 110 include, in Generally, a solar collector (for example, a luminescent solar collector, or LSC). At least one roof panel 110 (and preferably at least half of the roof panels 110) includes a solar collector. In some embodiments, walls 140, front panel 130, and / or rear panel also include a solar collector, depending on their orientation toward the sun. For example, a structure 100 located in the northern hemisphere and having east or west facing doors may include one or more solar collectors in or on the south facing wall.
    [0047] Even combinations of double or triple crops and evaporative greenhouses (for example, greenhouses adapted to collect and, optionally use evaporated water) allow the use of a water source that is not commonly used to irrigate crops, such as seawater or sewage, and are therefore novel combinations. Therefore, evaporative greenhouses can include structures and / or equipment for the desalination of water and have the ability to desalinate a saline solution or a brine (for example, water containing one or more salts) and use the desalinated water for the irrigation and / or cooling.
    [0048] For example, referring now to Figure 7, which shows a schematic representation of an evaporative greenhouse 700 by way of example, the cold brine inlet into the first and second water circuits at inlets 732 and 742 can form the cold part. (or condensation) heat exchanger on the "exhaust side" (that is, where the exhaust air 775 exits) of the evaporative greenhouse 700. The brine can be transported from deep sea water (for example, water from a depth of> 300 m,> 500 m or any other minimum depth greater than 300 m below sea level) or may come from another source (e.g. chemical manufacturing, water purification, fermentation or other biological production processes , food processing, mining, pulp and paper manufacturing, etc.). Pipes 734 that carry saline or brine to a 735 evaporator can pass through a 730 solar heater in the greenhouse roof 700 or other similar structure (for example, just below roof panels 710), in part to limit sunlight in regions with lots of sunlight (such as desert) to 760 plants, and also to absorb more solar heat or other energy on the roof 710 (under the solar collector panels 720). Thereafter, brine or other liquid based of water, now heated, passes into an evaporative medium (eg, evaporator 735, which may comprise a porous medium), through which air 775 is drawn in by one or more exhaust fans (not shown). Air 775 passes through evaporative medium 735, collecting water vapor (for example, absorbing evaporated water molecules) and potentially cooling the air. Downstream of the fan, the water vapor (now a source of fresh water) is condensed in / on a condenser 745. With a source of cold water (for example, the cold brine injected into the inlet 742 which eventually flows into the condenser 745), the evaporated water can be condensed on the exhaust side of the greenhouse 700. The condensate can be collected in one or more pipes 752 as fresh water for use as irrigation water for drip irrigation and / or fogging of plants ( for example, at 754 and / or 756). Alternatively, fresh water can simply be collected and sold or used for other purposes. The saltier brine exits evaporator 735 through outlet 736 (and then greenhouse 700) and can be used for salt production etc.
    [0049] Pipes 744 carry the brine from the inlet 742 to a second evaporator 740, through which the warm outside air 770 passes. The air 770 transfers heat to the brine, the air 770 absorbing some water vapor and cooling in the process. . The slightly warmer and slightly more concentrated brine then flows to condenser 745, where it is heated a little more before exiting the water circuit (and therefore the greenhouse 700) via outlet 746. If desired , some (or all) of the brine from condenser 745 can be recirculated back to evaporator 740 (eg, using one or more valves and pumps, not shown).
    [0050] Figure 2A is a graph 200 showing the visible light absorption spectra of various chlorophylls. For example, the visible light absorption spectrum of chlorophyll a is shown on line 210, the visible light absorption spectrum of chlorophyll d is shown on line 220, the visible light absorption spectrum of chlorophyll b is shown at line 230, and the visible light absorption spectrum of chlorophyll f is shown at line 240. The various chlorophylls do not absorb significantly in the 470-630 nm range, which means that light in this range Unfavorable can be used for other purposes (eg electricity generation, energy storage, etc.).
    [0051] Phycobiliproteins are photodynamic proteins that can drive photosynthesis and function as light receptors. For example, phycoerythrin shows a very intense fluorescence (for example, in the red band of the visible spectrum). A wide variety of phycobiliproteins can be produced from a fairly well characterized source. For example, cyanobacteria produce phycobilisomes, each containing ~ 1,500 pigments. The markets for phycobiliproteins include cosmetics, fluorescent markers, dyes, and biomaterials.
    [0052] Figure 2B is a graph showing the visible light absorption spectra of various phycobiliproteins compared to chlorophylls A and B. In the present structure and method, the solar collector advantageously uses phycobiliproteins (PBPs) to absorb light in bands of wavelength not used by chlorophylls and / or other photosynthetic plants and algae (eg, using photosystem II for photosynthesis). PBPs can emit light (which generally has a different wavelength) to an energy conversion device adjacent to at least one peripheral edge of the energy concentrator solar (eg, along a peripheral edge of a roof panel 110, at an interface between a roof panel 110 and a wall 140, etc.). Light not absorbed by PBPs passes through ceiling panels 110 into structure 100, which may include one or more supports or surfaces configured to allow plants and / or algae to receive the light that passes through roof panels 110. Thus, crops can comprise plants, and algae can be used to make beneficial chemicals and biological compounds and materials that can be harvested using known techniques.
    [0053] PBPs can be made UV stable and thermally tolerant by integrating them into a polymeric matrix (eg, a polymer film). Protection against UV radiation can also be provided with a UV blocking glass on top of the polymeric matrix, or another type or kind of composite UV film and / or filter can be used. Films, including PBP-containing polymer film, can adhere to glass. Alternatively, the absorbent (s) and / or fluorophores can be combined (eg, mixed) with one or more tardigrade proteins. Tardigrades can survive in outer space environments (for example, on the surface of a spacecraft), making them resistant to a wide variety of thermal, oxygen- and water-free, and UV environments. Their proteins, including the tardigrade-specific intrinsically disordered proteins (TDP) and / or a protein known as Dsup, are known to protect tardigrades from desiccation and may even protect the nucleic acids of animals from damage and / or stress. by high-energy radiation (for example, X-rays). Tardigrade proteins can also increase thermal stability and photochemistry of the absorber (s) and / or fluorophores that could otherwise degrade at high temperatures and / or under UV light stress.
    [0054] Photosynthetic efficiency is a useful factor in understanding the potential utilities of phycobiliproteins. For example, terrestrial plants typically have a photosynthetic efficiency of 0.2-2 % (for example, as exemplified by the photosynthetic efficiency of chlorophylls a and b), while some aquatic plants may have a photosynthetic efficiency greater than 8% ( for example, as exemplified by the photosynthetic efficiency of phycobiliprotein B-phycoerythrin from red algae).
    [0055] The potential revenues from products made from or including phycobiliproteins are quite high. For example, in the fluorescent marker market, calculations show that certain marine algae under nitrate-laden conditions can contain up to 0.05% phycoerythrin (PE) by fresh weight. PE has a value of up to US $ 300 / mg. That corresponds to US $ 15M / ton of fresh weight. The PE market will be US $ 4B in 2022, and possibly higher as the market (s) grow.
    [0056] Figure 3 is an exploded view of the layers of a luminescent dye-based solar energy collector 300, which can include a glass layer, sheet or plate 310 (which can be UV protection), the luminescent layer 320 (for eg, containing phycobiliprotein), and a reflective backing layer, film or sheet 330, which can direct emitted light (using total internal reflection) to the energy conversion device (eg, a photovoltaic [PV] cell). Alternatively, layer 320 may comprise an array of PV cells configured to generate electricity from light having a predetermined wavelength or wavelength band (which may overlap with the wavelengths or wavelength bands of light used by plants and algae for photosynthesis), and layer 330 can be the luminescent layer (e.g., containing phycobiliprotein), which can emit light that it has a wavelength or a wavelength band useful for photosynthesis in plants and / or algae. In a further alternative, layer 330 can be the luminescent layer (eg, containing phycobiliprotein), and layer 320 can be a light collection layer that focuses emitted light to PV cells at the periphery of collector 300. An example of the luminescent solar energy collector 300 can be found in United States patent application publication number 2012/0132278, the relevant parts of which are incorporated herein by reference.
    [0057] Figure 4A depicts various cycles of photosystem II, including the quinone depletion cycle and the S-state cycle. In photosystem II, enzymes capture photons of light to excite electrons, which are then transferred through various coenzymes and cofactors to reduce plastoquinone to plastoquinol. The excited electrons are replaced by electrons from water, which oxidize to form hydrogen ions and molecular oxygen. By replenishing the lost electrons with electrons from the dissociation of water, photosystem II provides the electrons for all photosynthesis to occur. Photosystem II (of cyanobacteria and green plants) generally contains approximately 20 subunits (depending on the organism), as well as other complementary light-gathering proteins. Each photosystem II contains one or more units of chlorophyll a 440, beta-carotene, pheophytin, plastoquinone, one or more hae groups, one or more bicarbonate ions, lipids 450, an oxide group of Mn-Ca (which may include chloride ions) , Union Fe2 + non-heme and possibly some Ca2 + ions. Figure 4B depicts the phycobilisome megacomplex 400. Elements 410, 420, and 430 identify the components of the phycobilisome, which include groups of phycocyanin and phycoerythrin molecules.
    [0058] FIG. 5 is a diagram of an exemplary solar concentrator 500 that may be implemented in or via the solar energy collector 300 of FIG. 3. Incident rays 510 from the sun can strike the solar concentrator 500 and pass through a roof. or top layer 520 of solar concentrator 500. Cover 520 can comprise a glass or plastic that is transparent to visible light and can absorb or reflect ultraviolet (UV) light. A plurality of luminescent centers 530 (only one of which is shown for clarity) are present throughout the solar concentrator 500. For example, in a horizontal cross-section of the solar concentrator 500, luminescent centers 530 are present substantially in the the entire major area or surface thereof (eg, other than the periphery and any waveguides that may be present). Luminescent centers 530 may be or comprise a phycobiliprotein (eg, in a polymeric matrix), a fucoxanthin, or a luminescent inorganic molecule or material. Thus, the luminescent centers 530 can absorb a specific solar radiation wavelength or wavelength band and emit light having a different (and usually longer) wavelength or wavelength band. In preferred embodiments, luminescent centers 530 are integrated into a polymeric matrix and are protected against damage (eg, denaturation) by or from the sun and / or heat, as described herein. document.
    [0059] The light emitted by the luminescent centers 530 can be absorbed by an energy conversion device 550, either directly (for example, by direct emissions 532) or indirectly (for example, by reflected emissions 534). Therefore, the solar concentrator 500 may include an underlayer or undercoat 540 (eg, a wavelength selector mirror) that reflects light that has the wavelength or wavelength band of the emitted light. by luminescent centers 530, but are transparent or substantially transparent to light having other wavelengths or wavelength bands. For example, the underlayer or undercoat 540 may fully or substantially completely reflect one wavelength or wavelength band of visible light, and be transparent or substantially transparent at some or all of the other wavelengths or bands of light. wavelength of visible light. Part of the emitted light 536 can escape from the solar concentrator 500 through the top layer or cover 520. To allow the maximum intensity of the incident rays 510 that have the same wavelength or wavelength band as the light emitted from Luminescent centers 530, cover, or top layer 520 may not include a wavelength selector mirror. Alternatively, if the intensity of the emissions from the luminescent centers 530 is greater than that of the solar radiation in the same wavelength or wavelength band, the cover or top layer 520 may include a length selector mirror wave configured to reflect light having a wavelength within the wavelength band of light emitted from luminescent centers 530.
    [0060] The energy conversion device 550 may comprise one or more photovoltaic (PV) cells (for example, to convert received light into electricity) or a photo-absorbent material in thermal contact or in communication with a heat exchanger that transfers heat to a fluid. working for storage in a heat storage tank or container. For example, the light absorbing material can be configured to absorb light having the wavelength or wavelength band of the light emitted by the luminescent centers 530, convert the absorbed light into heat, and transfer the heat through the heat exchanger. to the working fluid (for example, a gas or a liquid, such as water, a brine or a saline solution, a glycol [for example, ethylene glycol, propylene glycol, glycerol, etc.] or a mixture thereof with water, a molten salt, etc.). The heated working fluid can be transported through one or more insulated conduits to a storage container. The heated working fluid can be recovered from the storage container and used to heat the greenhouse or generate another form of energy (eg electricity) by a known process or method.
    [0061] Light 515 that is not absorbed by luminescent centers 530, reflected by lower layer or lower coating 540, absorbed by energy conversion device 550 or emitted through cover or upper layer 520 is transmitted through the underlayer or undercoat 540 to plants or algae (not shown in Figure 5). Optionally, when the energy conversion device 550 comprises one or more PV cells, some of the transmitted light can be absorbed by a solar heater (eg, the solar heater 730 of FIG. 7).
    [0062] FIG. 6 is a diagram showing the operation (s) of an exemplary solar light concentrator 600 in accordance with embodiments of the invention. Light 610 from the sun 615 is incident on the luminescent layer 620 of the solar concentrator 600. Light having a first wavelength or color (eg green light) is absorbed by a luminescent material or substance in the luminescent layer 620, which then emits a light that has a second wavelength or color (eg 625 red light). Red light 625 is reflected by a lower layer or coating 630 configured to selectively reflect red light and is received by one or more PV cells (not shown) along the peripheral edge (s) of solar concentrator 600. Other lengths waveforms or colors of light (eg, blue, green, yellow, violet, orange) pass through the bottom layer or coating 630. The red light received by the PV cell (s) is converted to electricity 640 and, in In this example, it is sold to a municipal, state, regional, or private electric utility and switched to a 645 electric grid. In one embodiment, the luminous solar concentrator 600 may be or comprise a LUMO panel commercially available from Soliculture, Scotts Valley, California.
    [0063] Fig. 8 is a diagram showing an exemplary structure 810 adapted / configured for a quadruple harvesting system 800 in accordance with embodiments of the invention. Structure 810 may comprise a smart home or greenhouse having a plurality of windows 812, 814, 815, 816, and 818, and one or more solar collector panels 820 having one or more PV cells along the periphery 824 of themselves or in a layer (eg, 822) thereof. Solar light 840 radiates from solar collector panels 820. Green light is captured by solar concentrators 820 (for For example, in a photoluminescent layer 830 comprising a plurality of randomly or directionally oriented 835a-z photoluminescent species in a matrix configured to support and / or orient the 835a-z photoluminescent species) and light (eg, light emitted by photoluminescent species 835a-z) to generate electricity is directed to PV cells as described herein. The photoluminescent layer 830 may comprise a plurality of photoluminescent sublayers 832, 834. At least the lowest photoluminescent sublayer 834 (and, in one embodiment, each of the photoluminescent sublayers) has a mirror or wavelength selector coating on it. lower part thereof, configured to reflect the light emitted by the photoluminescent species 835a-z towards the PV cell (s). Different colors or wavelengths of light are used (for example, red and blue light) that pass through the lower layer or back cover 826 of the solar collector panels 820 (some of which may have been generated by the solar collector panels 820) for the production of greenhouse crops. In addition to income from harvests, income from electricity production can additionally finance greenhouse production, increasing climate resilience.
    [0064] FIG. 9 is a flow chart 900 of an exemplary method for generating electricity and simultaneously growing crops in accordance with embodiments of the invention. At 910, a first wavelength or predetermined wavelength band of solar radiation (eg, green, violet or ultraviolet light) is absorbed with a luminescent material (eg, a phycobiliprotein or a dye) in a solar concentrator, as described herein. Then at 920, the luminescent material in the Solar concentrator emits radiation having a second predetermined wavelength or in a second predetermined wavelength band to one or more high voltage photovoltaic (PV) cells along one or more edges of the solar concentrator. Alternatively, the emitted radiation can be received by a material or substance configured to convert the emitted radiation into heat and transfer the heat to a heat storage medium (eg, the working fluid described herein). In some embodiments, the method may further comprise reflecting or otherwise directing at least part of the emitted radiation to the PV cells or the radiation absorbing material or substance.
    [0065] The second wavelength or predetermined wavelength band of radiation is generally longer than the first wavelength or predetermined wavelength band of radiation. For example, when the luminescent material absorbs ultraviolet light, the luminescent material can emit light in any band or have any wavelength in the visible spectrum. When the luminescent material absorbs violet light, the luminescent material can emit a light that has a longer wavelength or a different color (eg green light). Similarly, when the luminescent material absorbs green light, it can emit light in a longer wavelength band or have a longer wavelength (eg, red light).
    [0066] In parallel with 920-930, one or more additional wavelengths or wavelength bands of solar radiation can pass through the solar concentrator at 940, as described herein. The additional wavelengths or wavelength bands of solar radiation can have multiple uses. For example, in 950, low voltage PV cells below the solar concentrator they can be irradiated with the additional wavelength (s) or wavelength bands of solar radiation. For example, low voltage PV cells can be configured to absorb and convert yellow and / or orange light into electricity at 960. Alternatively, a solar heater (eg, as described herein) below the solar concentrator can be irradiated with the additional solar radiation wavelength (s) or wavelength bands. The solar heater can be used in a brine or salt water desalination process, as described herein. In 955, the plants and / or algae below the solar concentrator can be irradiated with different wavelengths and / or wavelength bands of solar radiation (for example, red and / or blue light), as described in the present document.
    [0067] In 965, it is determined whether the plants or algae are ready to be harvested. Typically, a farmer or crop scientist determines if the plants are ready for harvest, and a technician, biologist, or physiologist determines if the algae are ready for harvest. There may be one or more standard criteria for such determinations. For example, plants can have a certain minimum size or bear fruit or other crops that have a certain minimum size or color. Algae can produce a certain minimum concentration of a desired substance or compound.
    [0068] When the collection criterion (s) are met or a determination is made to collect in one way or another (for example, a certain period of time has elapsed since the cultivation of the plants or algae was started), the plants or the algae are harvested in 970 and a new crop of plants or algae is started (for example, they are planted or placed in tanks and / or on supports below the solar collector (s)) at 980. Normally, over the course of a year (for example, a period of 12 consecutive calendar months) a minimum of two or three cycles of growing and harvesting of plants / algae will take place at the beginning at the end.
    [0069] In parallel with the irradiation of the plants or algae in 955, the harvesting of the plants or algae in 970 and the beginning of a new harvest in 980, the electricity generated in 930 and 960 can be used to run electrical equipment in the greenhouse at 990. For example, one or more water pumps, fertilizer injectors, controllers, timers, lights, cameras, etc., in the greenhouse can be operated using the electricity generated at 930 and 960. Alternatively or additionally When method 900 includes desalination of brine or salt water, the fresh water produced by the method can also be used in the greenhouse to irrigate crops (eg en 955). In other alternatives, electricity and / or fresh water can be sold (for example, to a municipal, state, regional or private electricity or water supplier).
