[0002]

2. Description of the Related Art The use of wind energy for cultivation of agricultural products or cultivation of marine products has been actively performed recently. The reason is that the technology of large-scale horizontal wind turbines has rapidly developed and matured, and the power cost of wind power generation has become comparable to the power cost of conventional major commercial power such as nuclear power generation and thermal power generation. The main reason is the decline. Naturally, regarding the recent global environmental pollution problems caused by fossil energy-based use (carbon dioxide, SOx, NOx, fine particles, etc.) and nuclear energy use (accidental radioactive material leakage). The background is efforts to make use of the cleanliness of energy.

The tower, which is a rotary wing support tower, will be built on a foundation block installed on the sea floor, and the part below the sea level of the tower will be used for fishing reefs. The present invention does not conflict with this prior art. There are many other similar prior art examples,
None of the prior art examples conflicting with the present invention was found.

[0005] Regarding the above-mentioned prior art search, item 2)

[0008] Item 5) Technology related to marine product cultivation tower in the above-mentioned prior art survey: The survey items include artificial reefs, fish cages, seedling breeding discharge, artificial upwelling, etc., but the prior art against which the present invention conflicts Was not found. A number of applications have been filed for artificial reefs, which are means for cultivation and fishing of marine products.
There is one. From the viewpoint of cost, in each case, the marine product cultivation tower or the structure that performs the same function as the marine product cultivation tower is a unique facility, and the cost does not become zero.

A description will be given of the above-mentioned known technique, item A) the technique of the rotor support tower of the horizontal axis large wind power generator.
The so-called horizontal axis type is by far the largest number of commercial large-scale wind power generators in recent years, and the vertical axis type large-scale wind power generators represented by the Savonius type and the Darius type are rarely constructed. Here, large means commercial as of early 2001,
This means a 1.5 MW class, which is the class with the largest output, which is stably constructed in large numbers and has the largest output, or a class with 1.5 MW or more, though there are few construction examples.

FIG. 7B is a schematic view of a large-scale horizontal-axis wind power generator. The rotor 12 is supported by the rotor support tower 11. The rotating diameter φDbl of the rotor is about 66 m or more, which is larger than the blade length of the jumbo jet. The rotor support tower (also called a tower) is made of steel pipe and has a diameter φDtw of about 4 m to 6 m. Its height is approximately equal to the hub height Hhb and is about 60 m to 80 m, which is equivalent to the height of a 20- to 25-story high-rise building. FIG. 7 (a) schematically shows a medium-sized or smaller wind power generator having many construction examples before the early 1990s for reference and comparison. In this case, the rotor support tower is similar to a transmission tower.

Next, the above-mentioned known technique: B) A technique related to a plant factory will be described. In contrast to the open-field cultivation method of agricultural products, artificially cultivating the cultivation environment, alleviating the instability of the natural environment (instability of cold and warm, wind and rain, sunshine, diseases and insects, etc.), improving the yield, The technology for earning profit is the horticulture cultivation method. There are various stages depending on the degree to which the instability of the natural environment is reduced. One example of the least relaxed is tunnel cultivation of vegetables. Tunnel cultivation is a cultivation method that only provides a tunnel-shaped cover with vinyl on top of open-field cultivation. The effect is great, it has the effect of preventing harm from frost and the effect of keeping heat. Input costs and energy are relatively low. On the other hand, there is a completely controlled plant factory cultivation method for cultivating agricultural products by alleviating the influence of the natural environment by 100% (that is, completely eliminating or blocking the influence of the natural environment). In this case, the input cost and the input energy are large.
There are various cultivation methods, such as a greenhouse cultivation method and a glass house cultivation method, in the middle stage of the mitigation of the extremes.

The general definition of a plant factory is the following two items. (I) Definition of a completely controlled plant factory: A cultivation device for agricultural products by cultivation without soil, without natural sunlight, using artificial sunlight (lamp light), and completely enclosed and completely air-conditioned (temperature / humidity control). (II) Definition of quasi-perfectly controlled plant factory: A cultivation device for agricultural products by cultivation without soil, combined use of artificial sunlight and natural sunlight, completely enclosed / quasi-perfectly air-conditioned cultivation. The plant factory cultivation method is completely sealed, so there is no pest and disease,
No need for pesticides, multi-turn production / harvest by year-round cultivation,
It aims to generate high profits due to factors such as scientific management. On the other hand, construction costs and input energy costs are high.

The production items of the plant factory are leafy vegetables (lettuce,
Salad vegetables, spinach, watercress, etc.), fruits and vegetables (tomatoes, strawberries, melons, etc.), flowers (gerbera, etc.), medicinal herbs (digitaris, etc.), fungi (mushrooms, etc.). Of these, the current mainstream products of plant factories are leafy vegetables and fungi, and fruit vegetables are not the mainstream products and there are few examples. Fruit vegetables are mainly cultivated in non-closed space cultivation methods: cultivation methods such as glasshouse cultivation, greenhouse cultivation and open-field cultivation.

This is based on the following circumstances. That is: α) The plant factory is in short supply of light (that is, illuminance) with the technology as of the beginning of 2001. However, fruits and vegetables require high illumination for a long time. On the other hand, leaf vegetables often require relatively little required illuminance (required light quantity). This does not mean that technically it is not possible to achieve high illuminance, but simply that the input cost increases and the business becomes unprofitable. Examples of input costs are cooling operation costs (increased illuminance means increased input energy and the amount of heat stored in the enclosed space must be removed), cooling device installation costs, lamps' own costs, Such as lamp power costs. The cost of the lamp itself includes: 1. Lamp cost for the first operation after factory construction; 2. Replacement lamp cost for each lamp life; 3. Cost of power supply for lighting the lamp; The cost of lamp shades (such as lamp reflectors). β) In general, leafy vegetables have a short growth institution, and the annual number of rotations (the number of repetitions of sowing, growing, and harvesting in one year) is large.
It can rotate about 0 times. On the other hand, fruits and vegetables have a long growth mechanism and low rotation speed. The plant factory is a device that increases the annual number of rotations, obtains an equivalently large management area (that is, equivalent open-field equivalent area) with a small site area, and obtains high profits. Is suitable. Mushrooms are also suitable for plant factories because they do not require high illuminance. The management area is expressed by the following formula. * Is a multiplication symbol. Management area (equivalent open area conversion area) = (annual number of rotations) *
(Factory area).

The following mathematical formula clearly shows that the plant factories involved in plant factories have repeatedly and relentlessly attempted, challenged, and repeatedly attempted to make the plant factories three-dimensional and high-rise. Here, N is the number of floors (corresponding to the number of floors in an office building). Management area (equivalent open area conversion area) = (annual number of rotations) *
(Factory area) * N. That is, for example, a 20-story office building can accommodate 20 times as many employees as a one-story office building. Similarly, a 20-story high-rise plant factory would increase the business area by 20 times that of a one-story plant factory.

As an example, a cylindrical three-dimensional, high-rise plant factory having a radius of about 20 m, 20 layers, and a 10-year anniversary is equivalent to a 25 hectare large-scale open-field farm. However, open field cultivation is assumed to be harvested once a year. Operating area = about 25ha (= π * 20m * 20m * 20 layers * 10 rotations). However, in reality, plant factories appeared in the past under the spotlight, but are now on the decline. On the other hand, there are still many patent applications for high-rise plant factories. This is presumed to be due to the following circumstances. i) With increasing interest in global environmental pollution in recent years, there has been increasing interest in the cleanliness of plant factories that do not use pesticides. ii) The cost of wind-generated power, which is clean power, is approaching the cost of generated power that is polluting the global environment such as nuclear power and thermal power. iii) In addition to inducing the above i) and ii), the concept of a high-rise plant factory with a very small site area has a beautiful geometrical consistency if only practical aspects such as feasibility and realization cost are ignored. , Familiar to many patent inventors.

Next, known examples will be described. FIG. 8 shows a three-dimensional plant cultivation apparatus manufactured by Lusner of Austria, Europe. This three-dimensional plant cultivation apparatus has a columnar shape (roughly cylindrical tower) with a polygonal cross section, and its height Hpl reaches as much as 50 m. Construction was in the 1970s. The side surface of the general cylindrical tower is glass-covered and takes in natural sunlight 13. Therefore, it is not fully controlled. Lusner then switched to a fully controlled cultivation method using only artificial light sources, completely shutting off natural sunlight, but that method eventually disappeared (Source: Magazine, Greenhouse Horticulture, January 1999)
October issue, page 48, Masao Iwasaki). Swedish salad vegetable cultivation plant in Sweden and Whittacker salad vegetable cultivation plant in USA are also three-dimensional cultivation methods. U.S.-based Whittaker, a three-dimensional cultivation method, has also withdrawn (source: same as above). The tower greenhouse in Europe and the plant plant with completely artificial light seem to have disappeared, and there has been no significant progress in artificial light plant factories worldwide (Source: same as the above-mentioned magazine).

In the industry, the fact that the withdrawal or the disappearance of the production system usually proves that the profits did not increase, the cost was not satisfied, and that it did not reach other low-cost production systems. Often do. On the other hand, although it is not a three-dimensional and high-rise type but a one-story building type, there are many examples of actual operation and operation using artificial sunlight (lamp) as an auxiliary light source, so actual operation examples will be given. This example is a case of a plant factory having a feature in trough control of adjustment of a growth space accompanying growth of a plant (for example, JP-A-11-127711). This plant factory is a glazed Venlo series. The site area is 1,700 square meters, and the production items are salad na, leaf lettuce, salad spinach and others. In this case, natural sunlight is mainly used, and the artificial light source is an auxiliary light source (so-called auxiliary light type), so it is not a so-called completely controlled plant factory.

For clarity of explanation, the following classifications are made: ah
After all, the practical horticulture cultivation methods that have become practical are the following ae
The schemes that exist only in the domain of published and published patents are f and g below.
For comparison: the method of the present invention, which will be described in detail later, is the following h # # method name, building, surrounding wall, lamp, sun, product, rotation a) complete type * one-story * barrier * artificial light * positive * Hana * Aniversary b) Complete formula * Internal * Blocking wall * Artificial light * Yoshino * Hana * Aniversary c) Semi-complete * Hayaya * Glass * Artificial light * Sun * Hana * Aniversary d) House * Hayaya * Glass * peopleless * sun * all species * slight times e) house * one-story house * vinyl * peopleless * sun * all species * 1 time f) Complete formula * high-rise * wall cut-off * artificial light * yang mu * all species * Anniversary g) Complete formula * High rise * Glass * Artificial light * Sun * All species * Anniversary h) Semi-complete * High rise * Sheet * Artificial light * Sun * All species * Anniversary Here, abbreviations represent the following. # = Classification number, method name: complete formula = fully controlled plant factory, method name: semi-complete = quasi-completely controlled plant factory, method name: house = house cultivation method, building:

A description will be given along the above classification. a), b)
There is no example of a fully controlled, low-cost, high-rise plant factory (Lusner is expensive, not low-cost, and is therefore gone). The plant factories a) to c) can only cultivate leafy vegetables, and it is difficult to grow fruity vegetables. If the purpose is cultivation of fruits and vegetables, the method is d). That is, the plant factory system is abandoned, the agricultural plant is used, pesticides are used, year-round cultivation is abandoned, sunlight is introduced into the glasshouse cultivation greenhouse, and fruits and vegetables are produced. Since the year-round cultivation is abandoned, supplementary light with an artificial light source has little investment effect, and a system that does not use an artificial light source is more profitable. I.e. in a manner similar to d);
2) The use of artificial light sources is not profitable. There is no greenhouse-type plant factory. The reasons are cost of cooling and heating and material strength. This is because even if effective glass is used, the heat insulating property is better than vinyl, so that it is profitable. In addition, tears, cracks due to storms, aging, and tears due to weathering deterioration, etc. are the main features of plant factories and the maintenance of enclosed space, which is a major premise,
Make it impossible. If the hermeticity cannot be maintained, as a result of invasion of pests and insects, pesticide-free cultivation cannot be maintained and pesticide costs are required. Insulation performance deteriorates due to air leakage, and cooling and heating costs increase. The overwhelming majority of actual greenhouse horticultural cultivation apparatuses are the above-mentioned d) and e) methods, and a few examples are a) and
The b) and c) methods are used, and the f) and g) methods do not exist in the horticultural industry and exist only in the patent domain.

In the above, the practical aspects have been described mainly from the viewpoint of cost. On the other hand, there are numerous patent applications for three-dimensional high-rise cultivation apparatuses.
308860 is referred to as a reference number. Examples of patent applications from the viewpoint of location are land, sea, undersea,
There is an application for cultivation located in the air or extraterrestrial. There are also proposals to float in the air using the wind energy in strong altitudes with a westerly wind, and proposals for a plant cultivation apparatus located on the moon (Japanese Patent Laid-Open No. 7-75452). Naturally, there are many proposals for agriculture and fisheries located on floating artificial islands, etc., at sea with good wind conditions.

[0022]

As described above, the prior art has a problem in terms of cost. The problem to be solved by the present invention is to reduce the production cost of agricultural and marine products. The pursuit of lowering the production cost of agricultural and marine products inevitably leads to the pursuit of lowering the production cost of agricultural and marine products by improving the cultivation method including cultivation equipment. More specifically, the problem to be solved by the present invention is the pursuit of a low-cost method for cultivating agricultural and marine products on the background of a cultivation device that has not existed conventionally. More specifically, 1) construction cost of a semi-perfectly controlled plant factory, which is one type of agricultural product cultivation equipment,
The problem is how to reduce 2) cooling and heating costs, 3) glass costs, and 4) operating power costs. Similarly, lowering the production cost of marine products is due to the 5)
The challenge is how to reduce construction costs and 6) operating power costs. Agricultural product cultivation cost, marine product cultivation cost,
It is an issue to be solved how to reduce the cost of cultivating agricultural and marine products by combining both agriculture and water.

[0023]

In order to solve the above-mentioned problems, the present invention selects the following method. As mentioned above, subject 1)
Regarding the construction cost, the cultivation building (that is, the cultivation tower... Pay attention to the difference between the wing and the tower) and the rotary wing support tower are the same, and a means for substantially reducing the cost is taken. Problem 2) With respect to cooling and heating costs, measures to improve the heat insulation performance and utilize seawater cooling and heat sources are taken. Problem 3) Regarding glass cost, a measure is taken to achieve heat insulation performance and strength higher than glass without using glass by using a multilayer sheet. 4) Regarding the operating power cost, measures are taken to mount the wind power generator, and the system is not connected to the commercial power network. If these means are described more specifically, the following means described in the claims will be obtained. 1) Means 1: In an agricultural and marine product cultivation apparatus equipped with a horizontal axis large-scale wind power generator having an output of 1.5 MW or more, the agricultural and marine product cultivation tower is cultivated by also serving as a lower rotor support tower. 2) Means 2: When the means 1 is applied to an agricultural and marine product cultivation apparatus constructed on water, the cultivation wing on the water part is an agricultural cultivation tower and the cultivation wing below the water is a marine product cultivation tower. To grow. 3) Means 3: In any one of means 1 and 2, the agricultural product cultivation tower is provided with a sheet winding device for winding the flexible sheet around the agricultural product cultivation tower, and the agricultural and marine products are cultivated. 4) Means 4: In the means 3, cultivate agricultural and marine products by winding the flexible sheet around the agricultural product cultivation tower within one hour or unwinding the flexible sheet from the agricultural product cultivation tower within one hour. 5) Means 5: In means 3 or 4, cultivate agricultural and marine products by winding a plurality of types of flexible sheets around the agricultural product cultivation tower. 6) Means 6: In any one of means 1 to 5, cultivate agricultural and marine products in such a manner that the telescopic basic legs supporting the agricultural and marine product cultivation device at the lowermost part are monitored by electronic means and controlled to be driven to expand and contract. I do. The present invention achieves the reduction of the production cost of agricultural and marine products, which was a problem of the prior art, by the above-mentioned six new techniques and the later-described means 7 which have not existed before.

The problem of global environmental pollution involves the cost of decontamination. For example, inputting commercial power energy into an agricultural and marine product cultivation apparatus will eventually input energy including thermal power generation and nuclear power generation, which are sources of global environmental pollution, into the production of agricultural and marine products. As the carbon tax burden suggests, global warming, SOx / NOx, pesticides, leaked radioactive materials, and other global environmental pollution issues are the most costly issues in addition to the business ethics of agricultural and fishery producers. In view of the above, there is a possibility that large beneficiary costs will be burdened in the near future.
Some exceptions (isolated power without grid connection to commercial power and renewable power such as solar, wind, and hydroelectric power, using no other than generated power, using no fossil fuel for heating, pesticides Most conventional agricultural and marine product cultivation methods rely on fossil energy and nuclear energy, and are also a source of global environmental pollution. Therefore, the present invention considers not only the viewpoint of corporate ethics but also the future viewpoint of the burden cost of decontamination, and sets the following 7) as a standard to be followed in agricultural and marine product cultivation. 7) Means 7: Reduce the production cost of agricultural and marine products by a clean method that is not connected to the system and does not pollute the global environment.

[0025]

BEST MODE FOR CARRYING OUT THE INVENTION The location of an agricultural and marine product cultivation apparatus when the agricultural and marine product cultivation method according to the present invention is carried out is typically the following location. As described above, the present invention is an invention in which cost is the most important, and the location is also selected from the viewpoint of cost. The description of the embodiment will be given in the next paragraph.
Among the classifications, three examples of aa) an embodiment in which the vehicle is located in the near sea, bb) an embodiment in which the vehicle is located in the distant ocean, and cc) an embodiment in which the vehicle is located in an alpine area will be described later. In any case, the system is not connected to the commercial power network. In addition, water is above the sea, lakes and rivers, but for the sake of simplicity of explanation, the water above is representative of the sea. The invention does not exclude the possibility of application on lakes and rivers.

The classification of the location points is as follows: 5 classifications Inshore waters (on the continental shelf / coastal area) --- A-I-i Near territorial waters (inside / outside 12 nautical miles / floating type)- A-I-i Beach (including breakwater) --------- B-III-iii Alpine area (mountain area) --------- B-II-ii Far sea (Inside and outside of the 200 nautical miles water zone) --- C-I-i The conditions of the location point are that the wind conditions are good (the wind is strong and the wind direction is stable), that is, the power generation power is low cost, The main requirements are low site costs and the availability of low-cost cooling sources for cooling. Above symbol ABC
Is the order in which the wind condition is good, the symbol I II III is the order in which the site cost is low, and the symbol i iii iii is the order in which the cold source cost (seawater and beaches use seawater with as deep a depth as possible, and alpine mountains use outside air). . Naturally, this ranking is very rough and can be reversed significantly depending on the conditions (for example, whether or not there is a right to fish, the right to join a firewood, the right to join a grass, the presence of a grass cooperative, the distance from the coast, etc.). Things. Further, the location is determined in consideration of various conditions such as a viewpoint of distribution costs of produced agricultural and marine products, a viewpoint of costs for coping with public regulations, and the like.

A typical area with good wind conditions is a beach area, a near sea area and an alpine area. Wind conditions are good in coastal areas and near seas because there are few obstacles blocking the wind, and the sea breeze and land breeze are remarkable. In general, the wind is stronger at higher altitudes (an extreme example: the average annual wind speed at the top of Mt.
It can be understood intuitively that the clouds are moving even if there is no wind on the ground. Empirically, there is a mathematical formula expressed as a power of height. ) So the alpine area also has good wind conditions. Regarding the plains, there are many places where the wind conditions are good, such as local winds such as dips and unloading in plains with special terrain, and predominant winds are noticeable in the continental plains. It is not a representative location point of the present invention because it is expensive. Furthermore, low-cost cold heat sources are difficult to obtain in plains.

Next, the case of the location point aa) will be described. FIG. 1 is a schematic diagram in the case where the method for cultivating agricultural and marine products according to the present invention is implemented while being located on a nearshore sea. The agricultural and marine product cultivation apparatus 10 stands on the seabed level L6.
The rotor 29A of the wind power generator, which is the part in charge of energy of the agricultural and marine product cultivation apparatus, the generator 29 directly connected to the rotor
B is supported by an upper rotor support tower 1 and a lower rotor support tower 2. The lower rotor support tower 2 is composed of a plant factory, which is an agricultural product cultivation tower 3, and a marine product cultivation tower 4 below the plant factory. The lowermost part of the marine product cultivation tower 4 is a telescopic foundation leg 5. The lower rotor support tower is constituted by a frame 6 made of steel pipe. The present invention is different from the idea shown in FIG. FIG. 22 in which a cultivation space is simply added to the tower 11 of FIG. 7 showing a conventional technique is shown in FIG. ) It is different from the present invention which aims to eliminate the tower 11 itself.

In FIG. 1, the number N of layers of the agricultural product cultivation tower is N = 11 (ie, corresponding to 11 floors) for the sake of clarity, but actually N = 20 to 50. It is about. An artificial light source (lamp) is placed and installed on the ceiling of each layer. The parts corresponding to the cultivation tanks, such as cultivation pots and cultivation trays, are arranged on the floor equivalent parts of the respective layers in the same manner as in a normal plant factory or facility horticulture cultivation apparatus. The frame 6 is made of a steel pipe, and its structure is omitted for the sake of clarity of the drawing. For example, the cross section YY has a polygonal substantially circular cross sectional structure as shown in FIG. I have. In FIG. 2, the maintenance zone is also used for the elevating space in the tower,
Elevating equipment such as a simple elevator (not shown) is provided. It also serves as a space for power wiring from the wind power generator. The agricultural and marine product cultivation zone also has a frame structure made of steel pipes, and includes a vertical frame 6A and a horizontal frame 6B. On the first floor, an agricultural product cultivation device operation control room, a computer room, an agricultural and marine product storage room, a stuffing station for agricultural and marine product production engineers, and the like, which are not shown, are provided. The deck zone is a space for a sheet winding device described later. The entire space below the sea surface can be used as a space for growing marine products.

The frames 6, 6A and 6B are steel pipes having a cross section of several cm to 10 cm. Accordingly, expensive heavy construction equipment such as a large crane truck is unnecessary, and the construction cost is reduced. The present invention relates to a prior art that does not use any large construction heavy equipment such as a large crane truck for installing the rotor blades of a wind power generator (the same inventor as the present inventor and the same applicant as the inventor in the latter half of 2000). Wind power generation related technology). Therefore, in all the construction steps of the agricultural and marine product cultivation apparatus related to the present invention, a large construction heavy machine such as a large crane truck is not used, and the cost is reduced.

A typical example of the dimension is the rotating diameter φDb of the rotor blade.
l is 66m or more than 66m, diameter φDp of plant factory
l is about 40 m, and the diameter φDfr of the marine product cultivation tower is 50 m
It is about. Vertical dimension is based on sea level L5 0
Assuming that m is plus (+) above and minus (-) below, seabed level L6 = -30m, sea level L
5 = 0 m, deck level L4 = + about 18 m,
Plant factory level L3 = + about 60m, hub level L
2 = + 100m, Top level L1 = + 180m
Degree. FIG. 1 shows a vegetable production engineer 7 of a plant factory in order to obtain a schematic image of the size of the agricultural and marine product cultivation apparatus used in the agricultural and marine product cultivation method according to the present invention. An enlarged view of the vegetable production engineer 7 is shown in a dotted circle for easy viewing.

Here, the light amount relation of the plant factory is calculated to confirm the validity of the above-mentioned numerical values. The numerical values to be checked for validity are as follows. That is: 1) The diameter of the plant factory-40 m 2) The number of layers of the plant factory-20 layers 3) The output of the large wind power generator-1.5 MW The validity of the plant factory (I.e., the illuminance that is the source of photosynthesis) is approximately 10,000 lux or more. As described above, generally, the required illuminance of fruit vegetables is higher than the required illuminance of leaf vegetables. In order to be able to cultivate fruits and vegetables, the plant factory is based on a standard of about 10,000 lux, which is at least slightly closer to the saturated photosynthetic illumination.

The illuminance E (unit is looks) is calculated by the following formula. E = ((PW * TG * LG * PG * TH) / (S * D
H)) + D, S = N * π * R * R, where PW is the output of the large wind power generator = 1.5 MW, TG is the operating rate of the wind power generator = 30% = 0.3, LG Is the luminous efficiency of the lamp = 150 lumen / watt, PG is the fixture efficiency of the lamp = 80% = 0.8, TH is the time of day = 24 hours, S is the area of one layer of the high-rise plant factory, DH is 1
The photosynthetic time of the day = 8 hours, D is the contribution of sunlight, and is estimated at 4000 lux, N is the number of high layers = 20, π = 3.14, and R is the radius of the plant factory = 2
0 m. When the illuminance E is calculated, E = about 10400 lux.

Therefore, a combination of the above-mentioned numerical values (a high-rise plant factory with 20 layers, a large-scale wind power generator of 1.5 MW, a diameter of the plant factory of 40 m and a radius of 20 m) is appropriate. Also, as of 2001, the wind power generator must be a large wind power generator of 1.5 megawatts or more, which is the largest class among the commercially practical wind power generators, and the light intensity is insufficient at 1 megawatt, It interferes with photosynthesis.

Many cultivated plants having high saturated photosynthetic illuminance have tens of thousands of lux or more, and a large-scale wind power generator having a large output is expected to increase photosynthesis and further reduce production costs. . However, if an appropriate heat removing means is not used, the heat generated by the lamp causes burning of the cultivated plant. From the viewpoint of the illuminance of the plant factory, the higher the output of the wind power generator, the better. Since the electric power to be distributed to the operation of the agricultural and marine product cultivation apparatus is relatively small, it is omitted in the approximate stage such as this calculation. Also, the conversion efficiency of the storage system energy is omitted in the estimation stage. The maintenance zone does not require illumination and is not a cultivation area, but correction is omitted. Also, the contribution of natural sunlight was set to 4000 lux which was lower in consideration of the above omissions. When the summer solstice is high, the outdoor illuminance is 100,000 lux (100
It is understood that the above-described contribution illuminance setting is relatively low, considering that the illuminance may reach several thousand lux even in cloudy or rainy weather during the day.

In cultivation exclusively for leafy vegetables with low required illuminance, 20
In the case of a cultivation item in which the required illuminance is insufficient with the above-mentioned calculated values, a plant factory having more layers than layers is possible.
Create a resting layer, apply lighting power to a small number of layers,
A method of operating cultivation by obtaining a bright illuminance can be considered.

The telescopic basic leg will be described. The telescopic foundation leg absorbs the inclination when constructing the agricultural and marine product cultivation equipment, and absorbs the uneven settlement and the equal settlement due to the seabed subsidence after the construction. In general, it is known that the inclination of the seabed is gentle until reaching the edge of the continental shelf and steeply slopes from the edge of the continental shelf. If the slope is, for example, 5/1000 and the continental shelf margin depth is 200 m, the continental shelf margin will be 25 km from the coast by proportional calculation. Further, if the diameter φDfr of the marine product cultivation tower is 50 m, the dimension to be absorbed by the telescopic basic leg becomes 25 cm by proportional calculation.

FIG. 9 is a schematic view of a telescopic basic leg. The telescopic base leg 5 has a double-pipe structure of a steel pipe like a hydraulic cylinder, and the telescopic power is motor, hydraulic, pneumatic, or the like.
The expansion / contraction mechanism is any of hydraulic pressure, pneumatic pressure, a combination of a motor and a long screw mechanism (a ball screw mechanism, a trapezoidal screw mechanism, etc.), and the like. The above-mentioned size of 25 cm to be absorbed can be sufficiently covered, for example, by the stroke of an ordinary small hydraulic cylinder.

A load cell (also referred to as a strain gauge) and a stroke gauge (not shown) are attached to the telescopic basic leg, and the load applied to the telescopic basic leg and the load of the telescopic basic leg are electronically measured. The stroke length is detected.
Each load and each stroke length of the telescopic basic leg group are sent to a computer in a control room (not shown) of the agricultural and marine product cultivation apparatus by lightening a signal line (not shown). The computer also receives level information from electronic level sensors (not shown), which are arranged in a large number of agricultural and marine product cultivation apparatuses. Further, information from an anemometer and an anemometer (not shown) is also received.

From these information groups, the computer receives the unequal settlement amount (the amount of settlement after construction can be known by storing the stroke data at the beginning of construction) and the fluctuation of wind intensity to the agricultural and marine product cultivation apparatus. Overturning moment (Fig. 10
(A) describes the overturning moment. Like a tower,
A force acting on a structure having a small horizontal cross-sectional area and a high height, which is a force for overturning the structure (refer to FIG. 10B), and the like is calculated and determined, and an appropriate treatment is performed. do.
For uneven settlement, a control signal is transmitted to the stroke actuator 5A in FIG. 9 to perform a stroke adjustment process. Also, the cutout wind speed (the wind speed at which the brakes are forcibly stopped and the rotor blades stopped to prevent the generator output from becoming too large and causing the generator to burn out, is called the cutout wind speed) In order to reduce the overturning moment in the event of a storm that exceeds, as shown in FIG. 11, the stroke of the telescopic foundation legs is adjusted, and the entire agricultural and marine product cultivation apparatus is slightly inclined toward the windward to generate a reverse moment, thereby causing the overturning moment. Mitigation measures can also be taken. FIG. 11 is exaggerated for the sake of clarity.

In the event of an extreme storm, in order to prevent damage to the rotor blades, a rotor blade removal device (not shown) was filed in the second half of 2000 by the same application as the present inventor and applicant. 2), the rotor can be removed and stored in the maintenance zone of FIG. Furthermore, the cultivation of the plant factory will be temporarily suspended. As shown in FIG. 10a, it is possible to take measures such as temporary provision of the reinforcing wire rope 8, activation of a windproof function described later (the sheet winding device has this function), and the like.

In FIG. 1, the fish cultivation tower has
A, middle floating fish reef 4B, upwelling generator 4C, fixed net 4
D and other cultivation and catching equipment are installed. In addition, the frame structure of the marine product cultivation tower itself plays a multiple role of submerged fish reefs, floating fish reefs, middle floating fish reefs, and algae reefs. Furthermore, in addition to the fish reef function, it fulfills multiple functions such as anchoring a live cage, monitoring a live cage, and anchoring a fixed net.

The above-mentioned prior art patent, Japanese Patent Application Laid-Open No. 2000-2000
The concrete tower of 213451 is a big difference in that it is only a single function of a fish reef for attracting (collecting) fish. Furthermore, the area scale is qualitatively different. That is, while the diameter of the marine product cultivation zone (FIG. 2) of the present invention is about 50 m, the tower described in Japanese Patent Application Laid-Open No. 2000-213451 has a diameter of several meters due to its nature (even if the maximum is estimated to be 7 mm).
m does not exceed m), and the area ratio of the two becomes 100 times or more, and both are completely qualitatively different.

As shown in FIG. 3, the flexible sheet 9 is wound around the agricultural product cultivation tower 3. As shown in the figure, the winding method may be a continuous spiral winding or a discontinuous stepwise winding. FIG. 4A is a schematic diagram of a sheet winding method.
The sheet winding device 14 runs on two deck rails 15A on the deck level. The sheet winding device can run around the agricultural product cultivation tower. FIG. 4B is a view taken in the direction of arrows V-V in FIG. At the plant factory level, guide rails 15B are laid, and deck rails 15A
It has a function of guiding and reinforcing when the sheet wrapping device 14 running orbiting above runs.

FIG. 5A is a schematic view of a plane cross section of the sheet winding apparatus. The flexible sheet 3 is pulled out from the sheet roll 17 around which the flexible sheet is wound as the sheet winding device travels around. At this time, an electromagnetic powder brake (not shown) is operated to apply tension to the flexible sheet. Electromagnetic powder brakes may be those standardly used in the converter, plastic sheet and sheet film industries. Because of this tension, the flexible sheet can be tightly wound so as to maintain the complete tightness of the crop growing tower. Therefore, since a large force is applied to the sheet roll, the winding reinforcing frame 19 is arranged for reinforcing the strength. QQ arrow view is Fig.5
(B). FIG. 5B is a detailed schematic diagram of the sheet winding device. The sheet winding device 14 runs on rails via wheels 21. The sheet roll 17 around which the flexible sheet is wound is housed in a roll frame 18 and can move up and down along three frame guide shafts 16 as indicated by block arrows. There is a roll elevating wire 32 for this vertical movement, which is driven up and down by a roll elevating motor (not shown). In order to reinforce the strength of the sheet winding device, a winding reinforcing frame 19 is arranged at a necessary position. Although only one sheet roll is shown for the sake of clarity, a plurality of sheet rolls are arranged in the vertical direction to shorten the time required for winding, which will be described later. It can be raised and lowered at the same time.

The time for winding the sheet material in a closed manner over the entire surface of the agricultural product cultivation tower will be described. The sheet winding device is driven by a motor (not shown) which is supplied with electric power via a deck rail. The approximate value of the time required for winding the sheet, Tw, is calculated by the following equation. However, S = running speed at 10m / min, H = 50m,
D = 40 m is the height and diameter of the agricultural product cultivation tower, W = 4 m is the sheet width, and R = 5 is the number of rolls to be wound simultaneously. In addition, the amount of overlap in the vertical direction for maintaining the degree of sealing is omitted for the rough calculation. Note that W = 4 m and S = 10 m are values substantially below the level in the sheet industry, converter industry, or film industry, and there is sufficient margin. Tw = (π * D * H) / (W * S * R) = approximately 32 minutes Note that the same calculation is applied to rewinding as well.

In order to further reduce the winding time, FIG.
As shown in the conceptual diagram of the single turn method of No. 3, the agricultural product cultivation tower 1
The number of sheet rolls 17 necessary to cover the entire length in the height direction of 0 is installed in the sheet winding device, and the winding of the flexible sheet can be completed with only one rotation of the sheet winding device. Is natural. In this case, the roll elevating function becomes unnecessary. FIG. 13 shows an example of overlap winding. FIG. 14 is a schematic view of a plane cross section of FIG. A flexible sheet is fed from a sheet roll 17 installed inside the roll winding device 14.

For reference, the time required for sealing vinyl over the entire area of a greenhouse using the conventional greenhouse cultivation technique, which depends on the scale of the greenhouse, is not a problem. Assuming that the vinyl area is about the same as the cultivation tower (the vinyl area of a single-story greenhouse because there is no high-rise type greenhouse), it will take several days. As will be described later, it is impossible to remove and attach vinyl every morning and evening, which is possible in the present invention, since it takes several days to attach and detach as described above. Further, it is easily understood that it is extremely difficult to wind a sheet around a complex-shaped structure such as a multi-story structure while maintaining airtightness.

FIG. 6 shows a state where a plurality of types of flexible sheets 3 are wound around the agricultural product cultivation tower. FIG. 6 shows the inner flexible sheet 3.
A, the middle layer flexible sheet 3B, and the outer layer flexible sheet 3C are shown schematically in a state in which three types are wound. In addition, since the flexible sheet is wound tightly by applying tension, there is no gap as shown in the figure, but it is schematically illustrated for the sake of clarity of the figure.

Representative roles of the flexible sheet are as follows. I) Inner layer flexible sheet: always wound. A sheet with good transparency is selected to allow the cultivated plant to perform photosynthesis by transmitting the visible light wavelength region of the sun rays well. In many cases, the sheet remains wound for several years until the end of its life. It also plays a role in maintaining the hermeticity of the agricultural product cultivation tower. II) Intermediate layer flexible sheet: Temporarily wound in cold weather. Foamed plastic sheet, foamed styrene sheet, or near infrared /
A sheet having good heat insulating properties (heat insulating properties) such as a far-infrared shielding type laminated film is selected and contributes to the heat keeping in the agricultural product cultivation tower in cold weather. III) Outer flexible sheet: Temporarily wrapped during storms. A sheet with a high breaking strength is selected to protect the crop growing tower from storms such as typhoons.

Although an example of winding a flexible sheet has been described above, the present invention is not limited to this example.
For example, 1) Add a sheet structure to the outside of the inner flexible sheet layer to make a total of 4 layers, and wrap this additional sheet on days when ultraviolet rays are strong to increase weather resistance, and remove ultraviolet rays harmful to plants. 2) Insulating sheet is wrapped around only the lower part of the agricultural cultivation tower to increase the heat insulation effect only at the lower part, and the upper part of the agricultural cultivation tower where hot air is likely to stay,
Reduce the temperature difference in the lower part of the agricultural product cultivation tower where low-temperature air tends to stay. 3) As shown in FIG. 12, an adhesive tape roll wound with an adhesive tape 9D, which is one kind of a flexible sheet, is mounted on a sheet winding device, and the adhesive sheet is wound at the boundary of the flexible sheet 9 which does not overlap. The adhesive tape may be wound around a flexible sheet, which is wound or not shown, or when the flexible sheet is overlap-wrapped, and the like. As a result, the hermeticity of the agricultural product cultivation tower is further improved.

It is possible to wind a plurality of types of flexible sheets on a large-area cultivation tower such as an agricultural product cultivation tower within one hour in one short time step. Take an example. In the evening of spring and autumn, a heat insulating sheet (for example, the above-mentioned foam sheet) is wrapped around the agricultural product cultivation tower, and the agricultural product cultivation tower is kept warm during cool nights. When the morning sun rises sufficiently, the heat insulating sheet is rewound and removed, and only the transparent daylighting sheet (inner layer sheet) is used, and the sunlight required for photosynthesis of the cultivated plant is taken into the agricultural product cultivation tower. When the sun goes down in the evening, wrap the insulation sheet again. That is, the heat insulating property is good during the spring and autumn night when the outside air temperature is significantly low, so that the heating cost is reduced. During the spring and autumn day when the outside air temperature is slightly low, the daylighting sheet has good heat radiation, so that cooling becomes unnecessary. It would not be necessary to explain that if a foam sheet containing a large amount of stagnant air is used as a heat insulating sheet, it has a lower thermal conductivity than glass. As described above, it is possible to select a combination of flexible sheets that provides the greatest cost reduction effect according to changes in the season, the temperature, the weather, the weather, and the sunshine.

Further, an example will be given. The approach of a typhoon has come to be known from time to time due to the development of weather forecasting technology, the development of mass communication, and the development of the Internet. To protect the crop cultivation tower from storms, wrap a protective sheet in a short time and complete the protective measures. (The approach of a typhoon can be dangerous at least two days before.
In the case of layer winding, only 2 hours is sufficient if one layer is sufficient.) For gusts and the like, it is often sufficient to pay little attention to weather forecasts empirically, for example, in the spring storm, the first dead tree, etc. Needless to say, there is no warning, no warning, and no sudden gust of wind in one hour, except for a tornado. Therefore, it is sufficient to take countermeasures against storms after the signs of the storm appear.

As a matter of course, an automatic alarm may be issued to issue an alarm one hour before the danger comes. That is, for example, changes in wind speed, wind direction, air pressure, humidity, temperature, waves, and the like over time can be transmitted to a computer for controlling the operation of the agricultural and marine product cultivation apparatus via a sensor, and the danger can be automatically predicted. . This is foreseeable with simple computer software. Take an example. Predicting the approach of a typhoon (approaching the agricultural and marine product cultivation apparatus) two days in advance requires a huge amount of software, sensor information, and a database. This is because the typhoon is, for example, 1000 km away at that time.
However, it is easy to predict one hour before the approach because the above-mentioned sensor output clearly indicates the approach. That is, the typhoon is only several tens km away from the agricultural and marine product (since the traveling speed of the typhoon is several km to several tens km).

The sheet winding device also has a windproof function. FIG. 15 is a conceptual diagram visually illustrating the flow of wind.
If the sheet wrapping device 14 is arranged by rotating and moving on the deck so as to face the windward side, the flow of the wind becomes smooth, the turbulent component decreases, and the laminar flow component increases, as shown in the figure. As the laminar flow component increases, the external force applied to the agricultural product cultivation tower during a storm decreases. Therefore, the wind force that destroys or blows off the flexible sheet is reduced, and the flexible sheet can be protected from the storm. On the leeward side, if necessary, an air conditioner 31 having the same shape as the sheet winding device is provided,
Naturally, the laminarization performance may be further improved by reducing the turbulence and the vortex generated on the leeward side.

Next, the weight and cost of the flexible sheet and glass are compared roughly. Glass has a specific gravity of about 2.4. The thickness of the glass used in the plant factory is several mm (assuming 5 mm). On the other hand, since the flexible sheet is mainly made of plastic, its specific gravity is about 1.0. The thickness of the flexible sheet may be several tens of microns (for example, 50
Microns ... 0.05 mm). The thickness of the heat insulating sheet is about 200 microns (in the case of a foamed sheet, the weight calculation is performed, so that the air layer is equivalently crushed in calculation). The same applies to protective sheets and the like. The total thickness of the four layers is not more than 1 mm even if the maximum thickness is estimated. Therefore, if the area of both is the same, (flexible sheet 4
(Weight of layer): (glass weight) = (specific gravity 1 * thickness 1 m)
m): (specific gravity 2.4 * thickness 5 mm) = 1: 12, and the glass type is about 12 times (by orders of magnitude) heavier than the flexible sheet type. It would also be unnecessary to explain that glass costs are higher than plastic costs (eg, polyethylene sheets are used in disposable garbage bags, and PET sheets are used in disposable plastic bottles for beverages). Further, the glass type requires a dedicated window frame cost, the cost of hermetic sealing rubber for the window frame portion, and the cost of carrying heavy goods.

In summary, the new technology has at least the following effects, even if conservatively estimated. 1) Insulation effect: reduction of cooling and heating costs for agricultural product cultivation towers, 2) Heat radiation effect: reduction of cooling costs, 3) Reinforcement effect: protection against storms, 4) No need for glass: construction cost 5) Light weight effect ・ ・ ・ Reduction of construction cost, 6) Light weight effect ・ ・ ・ Light weight of agricultural and marine product cultivation tower,

Next, a second embodiment of the present invention, that is, a case where the apparatus is located in the above-mentioned bb) pelagic ocean will be described. As shown in FIG. 16, in the case of an offshore location, the agricultural and marine product cultivation apparatus 10 is connected to a truss road 22 (the structure of which is schematically shown as a truss road 22 in FIG. 18). The ridges are connected to form a multi-row agricultural and marine product cultivation apparatus 20. As shown in FIG. 17, a number of connected agricultural and marine product cultivation apparatuses are connected by a truss road 22 to form a marine agricultural and fishing village 30. The truss road is for a vehicle 21 or a human passage as shown in FIG.

The above-mentioned multi-cultural agricultural and marine product cultivation apparatus is constructed on the coastal sea (shallow continental shelf). The multi-floor agricultural and marine product cultivation equipment is equipped with a number of floats 23 after construction,
Inject air into the float and let it float. FIG. 19 schematically shows a state in which the float 23 is attached and the multicultural agricultural and marine product cultivation apparatus is raised. Since the truss road 22 has a long span, it is supported by a plurality of floating piers 25. A pier float 24 is attached to the floating pier to generate buoyancy. The pier float is filled with a computer controlled amount of air. A load signal and an inclination signal are transmitted from a load cell and an inclination sensor (not shown) to the computer. From this information, the computer constantly calculates the optimum buoyancy in real time, and sends an air injection command and an air discharge command to an actuator (not shown).

Since the agricultural and marine product cultivation apparatus is floating on the sea, a height difference is generated (floating up and down) as shown in FIG. Therefore, the truss road 22 needs to be connected to a device having both functions of absorbing the inclination and absorbing the expansion and contraction of the span. An entrance device 27 is provided for this purpose. The entrance device employs a normal mechanism such as absorbing a tilt by a hinge mechanism and absorbing expansion and contraction by a slide mechanism.

The multicultural agricultural and marine product cultivation apparatus is towed to a predetermined sea area and is moored by an anchor or the like. A large number of connected agricultural and marine product cultivation apparatuses are sequentially connected by truss roads in a predetermined sea area to form a marine agricultural and fishing village. In order to provide a stable supply of energy, the marine farming village has an energy building. The non-storage system energy of this marine farming and fishing village is mainly wind energy, solar heat and sunlight are the secondary energy, the storage system energy medium is hydrogen, and the storage system energy generator is a fuel cell.

The energy building is also equipped with a large wind power generator, and has the same shape as the agricultural and marine product cultivation apparatus. A flexible sheet is not wrapped around the side of the agricultural product cultivation tower, and a solar cell panel or the like is attached instead.
The energy building does not cultivate agricultural and marine products, but uses its wind power to produce, store, and supply hydrogen. FIG.
Is a hydrogen distribution system inside a marine agricultural and fishing village. The solar collector 28COL in the energy building 28 is a three-dimensional solar heat concentrator using a paraboloid of revolution as a condensing means.
Pump seawater and pass it through the focus of the solar collector,
Bring to a boil to obtain pure water with a purity close to that of distilled water. Pure water is stored in the main pure water tank 28WTA. Pure water generates hydrogen by applying power from a wind power generator to an SPE water electrolyzer (solid polymer electrolyte type water electrolyzer) applying the principle of electrolysis. When the weather is fine, power generated by the solar power generation device 28SLC in which the solar cell arrays are arranged is also supplied. The obtained hydrogen is stored in the main hydrogen tank. The above will be done in the energy building.

The main hydrogen tank and the main pure water tank have a hydrogen pipe network 28HPN and a pure water pipe network 28WNT, respectively.
Are connected to supply hydrogen to the local hydrogen tanks 10LTK and pure water to the local pure water tanks 10LTW via the piping network. Each of the agricultural and marine product cultivation apparatuses 10 has a local hydrogen production apparatus 10L in addition to the above-described local pure water tank and local hydrogen tank.
HG, a local fuel cell 10LPW is equipped.
When the wind power is strong and surplus power is generated, the generated power is supplied to a local hydrogen production device to produce hydrogen. When the wind power is weak and the power required for cultivation is insufficient, the stored hydrogen is supplied to a local fuel cell to generate power and obtain power. The local fuel cell is a PAFC (phosphoric acid) fuel cell.

After all, hydrogen is supplied to the local hydrogen tank in two ways: hydrogen supplied from the energy building and hydrogen from the local hydrogen production apparatus, and the stability of the hydrogen supply system is realized. In this manner, wind, which is unstable non-storage energy, is stored using hydrogen as a storage medium, and stable power supply is realized, thereby enabling stable agricultural and marine product cultivation. The hydrogen-related energy storage method may be applied to the first embodiment (located near the sea) in the embodiment of the present invention.

As described above, seawater can be used as a cold heat source when located on the sea, including on the coastal waters. Seawater is pumped from a deep part and supplied to the heat exchanger as a primary-side cold heat source to cool the secondary-side circulating water. The circulating water on the secondary side is piped into the agricultural product cultivation tower to cool the inside of the agricultural product cultivation tower.

Next, the third embodiment of the invention, c
c) The case of being located in an alpine area will be described. Here, the alpine area is an altitude of 1 where cool outside air can be used as a cold heat source.
The mountain range is around 000m to 1500m. The higher the altitude, the stronger the wind, but the outside temperature may be too cool. It is also necessary to consider sunshine and snow. With the exception of cold district agriculture, altitudes are limited to about 1100 m, so land costs are relatively low without the constraints of agriculture. However, there are many constraints such as security forests, parks, national forests, and forests. In determining the location point, these are also converted into costs and used as consideration conditions.

Gust (turbulence such as gusts), which is always a problem when constructing a wind power generator on an alpine mountain, does not cause much problem in the present invention. This is because in the present invention, there are few limiting factors for the height of the hub as seen in the tower system.
It is possible to increase the hub height appropriately without causing a significant increase in cost (see the above-mentioned patent application of the present inventor and the same inventor as the present inventor in the latter half of 2000). This is because the rotor is manufactured inside the lower rotor support tower (using the technique of (1)), and the rotor can be mounted without using any heavy construction equipment such as a crane truck.

In the case of being located in an alpine area, it is located on a slope as in the case of being located near the sea. Concrete casting for strengthening the ground, which is performed in the case of the construction of the conventional wind power generator, is not performed in the case of the present invention. Even in the case of a medium-sized wind power generator, the concrete casting amount exceeds 1000 tons. Carrying large amounts of concrete into alpine areas, aside from flat terrain, generally translates into higher costs in alpine areas with extremely poor road conditions. Therefore, the telescopic foundation leg of the present invention works effectively during construction. Furthermore, even if there is uneven settlement of the ground after the construction, the situation that works effectively is the same as in the case of nearshore location. Therefore, the overall shape of the agricultural and marine product cultivation apparatus is the same as that in the case of being located near the sea. However, the hub height is
As described above, the height may be appropriately increased.

The difference from the case of the near-sea location is whether or not a marine product cultivation device is attached. If it is an alpine area where fisheries are profitable (that is, if it is an area where the sale and distribution of produced marine products is advantageous), an alpine cultivation fishery will be established with appropriate aquariums, etc., and there will be doubts about the profitability of the fishery. Then, it is naturally possible to convert (change) the marine product cultivation device part to the agricultural product cultivation device, because energy conditions allow.

As described above, in the case of an alpine location, the cold heat source uses outside air (the alpine area is cool). In this case, the heat exchanger has air on the primary side and circulating water or antifreeze on the secondary side. Cooling tower heat exchangers are not suitable because of the risk of freezing during severe cold weather. Heat exchangers are quite different from offshore locations. The Takayama area requires proper consideration for the cold season. It has been empirically known that the rotor blades of the wind power generator hardly suffer from icing, icing, and snow accretion.

[0071]

As described above, as a result of the present invention,
The original goal, a clean method that does not pollute the global environment, will reduce the production costs of agricultural and marine products. To recap the conclusions briefly: 1) The use of wind power is clean and does not pollute the global environment. 2) Since it is not connected to the grid, it does not use commercial power, which is also a source of global environmental pollution, and is therefore a clean method. 3) Since there is no system connection, the cost required for system connection is unnecessary. 4) Since the agricultural and marine product cultivation tower also serves as the lower rotor support tower,
In the construction of the wind turbine generator, the cost of the rotor support tower can be reduced. 5) Low cost because no glass is used. 6) Low cost because it is not located on flat land where land cost is high. 7) Since the marine product cultivation tower can be used as a part of the structure of various marine product cultivation devices, the cost is reduced accordingly. 8) Cooling cost can be reduced because a low-cost cooling source can be used.
