Description

Technical Field

[0001] The present invention relates to a proposal by an ocean research institute for a system that floats a floating wooden artificial island on the sea or a lake, grows seaweed or freshwater algae in a culture soil unit suspended by a wire from the wooden artificial island, and reduces CO2 through the photosynthesis of the seaweed or freshwater algae, that is, a so-called blue carbon technology. Blue carbon refers to the carbon absorbed and stored in the marine environment by the activities of marine organisms. The annual CO2 emissions due to human activities amount to approximately 9.4 billion tons in terms of carbon, but plants such as forests on land absorb about 1.9 billion tons, and the entire ocean absorbs about 2.5 billion tons, of which about 1.1 billion tons of CO2 is absorbed by blue carbon ecosystems. The carbon fixed by plants on land is decomposed again by microorganisms in units of decades and released into the atmosphere as CO2. On the other hand, the carbon accumulated on the seabed is in an oxygen-free state, so the decomposition by microorganisms is suppressed, and the decomposition is extremely slow, taking thousands of years. Due to such characteristics, blue carbon has attracted attention as a new absorption source for CO2, which is the cause of global warming.

Background Art

[0002] Conventionally, seaweeds that produce blue carbon have been left to grow in the natural environment, and are extremely limited to shallow waters where sunlight reaches (= 0.2% of the entire ocean). Due to the installation of ports and the expansion of tourism development and commercial facilities such as beaches, the growth area has decreased but has never increased. In addition, there are times when sunlight does not reach sufficiently due to weather or tidal fluctuations, and it has not been in a sufficient growth state. Furthermore, the growth of algae may also be inhibited by the occurrence of red tides.

Modes for Carrying Out the Invention

[0008] Under the lower side of the wooden artificial island unit floating on the ocean or between multiple wooden artificial island units, the buoyancy of multiple sealed wooden boxes is used to lighten the culture soil unit, and then the culture soil unit is suspended by four wires, and algae cultivation is carried out on the culture soil unit. In addition, a residence is set on the wooden artificial island so that researchers can live there. Towards the flow direction of the ocean current, a narrow flow path is set between multiple wooden artificial island units, a large waterwheel is installed along the flow path, and a current guide is set between the wooden artificial island units to narrow the flow of the relatively wide ocean current to increase the flow velocity of the ocean current, rotate the large waterwheel at a relatively high speed, and perform wave power generation. A plurality of screws controlled by AI are installed on the wooden artificial island, the screws are operated to prevent the wooden artificial island from moving due to the flow of the ocean current, and maintain the position on GPS in the ocean. If the power for the operation of the screws to maintain the position on GPS at sea is insufficient, a separate tree-type solar power generation system will be installed on the wooden artificial island.

[0009] In Figure 1, the wooden artificial island unit refers to a wooden frame of □12m. The buoyancy of sealed wooden boxes of the required size and number from below offsets the weight of the load on the wooden artificial island unit to maintain buoyancy balance. (See Figure 3) The culture soil unit is soil with nutrients necessary for the growth of algae placed on the wooden frame. Since it is a heavy object, after maintaining buoyancy balance with a plurality of the sealed wooden boxes, the four corners of the wooden frame are suspended from the wooden artificial island unit with wires. Below the wooden artificial island unit floating on the sea or between a plurality of wooden artificial island units, the buoyancy of a plurality of sealed wooden boxes reduces the weight of the culture soil unit, A marine research institute that suspends the culture soil unit with four wires and conducts algae farming and research on the culture soil unit. A residence is set on the wooden artificial island so that a plurality of researchers can live there. A narrow flow path is set between a plurality of wooden artificial islands facing the flow of the ocean current, and a large waterwheel is installed along the flow path. A current guide is set on the wooden artificial island to narrow the flow of the broad ocean current to increase the flow velocity of the ocean current, rotate the large waterwheel faster than the flow of the ocean current, and perform wave power generation. A plurality of AI-controlled screws are installed on the wooden artificial island, and the AI operates the screws to prevent the wooden artificial island from moving due to the flow of the ocean current and maintain the position on GPS. Install a plurality of screws controlled by AI on the wooden artificial island, and the AI operates the screws to prevent the wooden artificial island from moving due to the flow of the ocean current and maintain the position on GPS at sea. When the direction of the ocean current changes, the AI adjusts the operation (rotation speed) balance of the plurality of screws to correct the orientation of the wooden artificial island so that the rotation direction of the large waterwheel always faces the flow of the ocean current. If the power for the operation of the screw to maintain the position on GPS on the ocean surface is insufficient, a separate tree-type solar power generation system will be installed on the wooden artificial island.

[0010] Figure 2 shows an overview of the algae cultivation on the wooden artificial island. Figure 3 shows an overview of the wooden artificial island. An angle of □12m is assembled with wood to form the basic unit of the wooden artificial island. Also, in Figure 2, there are 6 basic units of the wooden artificial island, but the basic units of the wooden artificial island can be extended by adding more in the direction of the arrow, and a large artificial island with a length of several kilometers or more can be formed. Regarding the expansion of the wooden artificial island, holes are drilled on the side surface of the angle, positioned with wooden rivets, and then the angles are adhered to each other for expansion. That is, by expanding the wooden artificial island, it becomes possible to install a number of large water turbines and generators, etc., and more large-scale power generation can be carried out. Also, by increasing or decreasing the number of sealed wooden boxes (a cube with each side of 2m = about 8t of buoyancy), the balance with the loading weight can be achieved.

[0011] Figure 4 shows an overview of the wave power generation of the wooden artificial island. A plurality of wooden artificial island units are set along the coast, and a narrow flow path: 0.6m is set perpendicular to the coastline between the wooden artificial island units. A large water turbine with a diameter of 19m and a width of 0.4m with a water scoop is set along the flow path. Also, a sea current guide is set for the plurality of wooden artificial island units on the opposite side of the coastline, and the flow of the waves coming towards the coast is gradually narrowed and guided into the narrow flow path, increasing the flow velocity of the waves, rotating the large water turbine at a relatively high speed, and generating electricity. Also, the shaft and bearings of the water turbine are set, and a gear is interlocked with the shaft of the water turbine. By this gear, a plurality of gears in the gearbox rotate, and by the gearbox, the rotation from the water turbine is accelerated, and the generator can be rotated at a high speed. Furthermore, surround the multiple wooden artificial islands with a plurality of fixed support columns so that they do not move due to ocean currents. The fixed support columns restrict the horizontal movement of the multiple wooden artificial islands but do not restrict their vertical movement at all. The multiple wooden artificial islands can move freely up and down in response to the ebb and flow of the tides. Generally, the direction of ocean currents progresses along the land, that is, parallel to the coastline, but it has the property of "waves tending to move in a shallower direction". As the water becomes shallower, it becomes a resistance to the waves, and while reducing the wave speed, it has the property of moving in a shallower direction, that is, towards the coastline. On the other hand, according to Bernoulli's theorem, "the flow velocity is approximately inversely proportional to the flow path width". By taking the largest possible ratio, that is, by changing the 12m flow path that can be made with the size of a standard wooden artificial island unit to 0.6m, there is a theoretical acceleration of 24 times. In practice, the flow velocity at the first-stage waterwheel is about 10 times or more, and at the second stage, it is also about 10 times. Furthermore, the energy of water is 770 times that of air. Since the waterwheel rotates with a large torque, the acceleration by the gearbox is effective, that is, it becomes possible to generate electricity with a large capacity for 24 hours.

[0012] Fig. 5 shows an overview of the tree-type solar power generation system. The tree-type solar power generation system "Patent No. 6656522" has an installation efficiency of 40 times that of a standard megasolar in its standard form, has a storage function, is resistant to strong winds, and is also strong against snow and sandstorms. In addition, it coexists with the surrounding nature and existing buildings without causing environmental damage. Furthermore, when installed on a wooden artificial island in the ocean, a foundation is not required, and it only needs to be fixed to the wooden frame. It is also possible to expect power generation even in the morning and evening sun (including the reflected light on the sea). It comes with an edge (AI) computer built-in with a program for the exact tracking angle for 365 days. By inputting the latitude of the installation location, etc., and also the calibration value at the installation site of each wire winder (with an encoder built-in), automatic and accurate sunlight tracking becomes possible. (Since it does not generate electricity at night), it is equipped with a battery, and has a unit configuration with the battery, a computer with AI, and a camera. It knows the wind strength from the swaying situation of the trees in the lamella image, and from the snowfall situation, it can store the light receiving panel in a storage box or make the light receiving panel vertical. The AI is connected to the smartphone via Wi-Fi communication, and can be manually operated with a smartphone app. Each panel can be moved to a position that is easy to clean, and the operator can clean the solar panel with a brush while watering.

By deploying the blue carbon of wooden artificial islands around the world, it may be possible to achieve carbon neutrality without waiting until 2050.
