The tidal current power generation system on the artificial wooden island is based entirely on classical principles, but it has a simple structure in which a square 12m wooden frame is made to maintain buoyancy with a closed wooden box. I think it's no exaggeration to call it the greatest invention of the century.
The wooden artificial island consists of square 12m wooden angles (square square 12m angles are positioned with φ100mm wooden rivets, glued with bonds, and connected horizontally to make a large artificial island), and the loading weight is The buoyancy is adjusted by adjusting the volume and number of wooden sealed boxes according to the requirements, and it is low cost, quick delivery, and highly safe.
In terms of safety, if a conventional ship is submerged, there is a high probability that it will sink and people will go missing. Even if it is destroyed, it will sink once, but if it is turned upside down by a heavy load and the load sinks to the bottom of the sea, the wooden frame of the artificial wooden island will rise again. There is a gap so people and pets can climb on and wait for rescue.
In addition, the artificial wooden island has a very high added value, and it is easy to level out various renewable energy installations. (Compared to the conventional base fixed type), it will be extremely low cost.
Solar power and wind power are said to have a lifespan of about 20 years, but wood lasts a long time underwater (experimental results), and wooden buildings such as temples have been maintained for hundreds of years. However, it lasts for a long time, but there is only one drawback: it deteriorates quickly when it is repeatedly wetted and dried, but by applying a liquid glass coating, this drawback is eliminated, and it is said that it can be maintained for 50 to 100 years. thinking about.
In addition, it is highly recyclable and contributes to a virtuous cycle of forests.
In the upper and middle reaches of the river, the flow is generally low, and it is not possible to float the wooden artificial island as it is. Installing a water wheel on the bank of a river is costly because the ground is loose and it needs to be firmly fixed to prevent it from being swept away by rising water levels or floods. It only needs to be placed on a fixed base on a wooden frame, and the structure is simple and the cost is low.
In addition, there is no need to fix the wooden artificial island in the pool, it is self-aligning with the water flow, and there is a great advantage that the positional relationship between the water level and the water wheel is constant even when the water level increases or decreases.
Freshwater aquaculture and hydroponics are also possible in the pool, and carbon neutrality and food self-sufficiency rate are 100% or close to 100% by setting pools & wooden artificial islands & waterwheels in rivers all over Japan. becomes possible.
Next, we will introduce tidal current power generation in which water turbines are installed on artificial wooden islands in the ocean.
If there is even a slight tidal current, by guiding the ocean current widely and narrowly (by applying Bernoulli's theorem), the tidal current will be accelerated, and the gearbox will increase the rotation speed to turn the generator and generate electricity. . (Because the tide changes, we use a reversible generator.)
Compared to air energy, water energy is 770 times more, enabling large-capacity power generation 24 hours a day.
<The evaluation points for each power generation system are summarized below.> ＞
1.Wooden Island Tidal Power Generation : 100 points: A huge amount of energy, not affected by the weather.
2.River pool water flow power generation: 100 points: Stable water level against fluctuations in river water volume, strong against floods and earthquakes, self-aligning, no fixing required, and continuous water turbines.
3. Wooden artificial island tree type: 40 points: 40 times the installation efficiency of mega solar. Suitable for snow and strong winds.
Four. Wooden artificial island wind power generation: 20 points: No foundation required, low installation cost (cannot generate power if the wind is weak)
5. Tree type on land: 30 points: requires a solid foundation, high installation cost
6. Offshore wind power generation: 1 point: It requires a solid foundation offshore, and the installation cost is very high.
7. Onshore wind power generation: 0 points: causes environmental destruction of deforestation. cause health problems.
8. Mega solar: 0 points: Takes up space and causes environmental destruction. Weak against snow.
Renewable energy, which is currently mainstream, has a score of 20 or less, which means that it should not be recommended anymore.
Especially for onshore wind power generation, it is necessary to cut down the surrounding forest on a large scale in order to improve ventilation, and since it is installed in the mountains, (installation & maintenance) road maintenance etc. are also involved, which has a large impact on the environment. . In addition, hearing health damage has also been pointed out. (so 0 points)
In conclusion, the top two items based on wooden artificial islands have the triple threat of cost, delivery time, and large-capacity power generation, are highly safe, and contribute to a virtuous cycle of forests. We should move quickly around the world.
Even if we proceed with offshore wind power generation, the cost of a strong foundation that can withstand typhoons and earthquakes will be high (on shallow waters). I think.
"Recommended operation power generation system ranking"
1. Cities along the coast are man-made islands - tidal power generation & seafood farming (traditional fisheries to shrink)
2. A city in a mountainous area is a swimming pool, an artificial island with a wooden elephant, and water current power generation.
3. Tree-type solar power generation in depopulated areas without suitable rivers and residential areas with many vacant lots
<Suggestions on how to proceed>
As the "first step", 16 square 12m wooden artificial island units will be created and various basic studies will be conducted. The contents of the basic study include "precision processing technology for wood", flow velocity measurement by changing the overall orientation and the width of the seawater inlet (verification of Bernoulli's theorem), "20m class large wooden water turbine", "wooden Large bearing part" & "Can seawater be used to lubricate the bearing?" "Generator with multi-stage acceleration gear"
"Marine garbage collection system (in the future, robots will periodically pick up garbage and place it in trays on self-driving trolleys)"
As for how to use the flow channel adjustment plate, when the tide flow is strong, it becomes parallel to the flow, and there is almost no seawater pressure, and when the tide flow is weak, the seawater is taken in more widely. It opens wide, but there is no problem because the seawater is weak.
"Newly added materials", in the middle and upper reaches of the river, the flow rate of the river is low, and it is necessary to install a pool, but in the lower reaches (especially in urban areas), the river guides are made of concrete, and new maintenance is especially necessary. The installation can be completed in as little as three days by lifting various parts with a crane and installing them in order.
The amount of power generated by the river 24 hours a day is huge, but there is also the merit that the river will be reborn as a place of relaxation with flowerbeds and chairs.
It shows the image balance of the basic concept, and it would be helpful if the local designer could understand the local natural environment and decide the details when actually designing.
We also hope that by disclosing and sharing this information globally, the system as a whole will become even better.
In the "second step," we are thinking of trying a marine product farming system.
In the 'third step', we are considering expanding the scale of tidal power generation and combining seafood farming systems.
For example, on the upper side of seafood farming, it is possible to set processing plants such as canning factories, restaurants and stores selling seafood. We also think that it would be all right if a residential area was built on an artificial wooden island and a new fishing port was built after that.
