1. Preface
In these days to marine resources much attention is increasing. It becomes more difficult toimport or export resources, by the political and economic strategic relations between
resource rich countries and resource poor countries. As for the rare earth elements or thethe rare metal which will support science, engineering in the future, the fact is know that
there is maldistribution in such as China. All the world countries make efforts in the
exploration of the resources of an own country in the land and the developing countries. In
addition, the exploration leaves the land and goes to the ocean now. In recent years there
were such the resources of rare earth elements or the rare metal in the bottom of theJapanese sea near the shore abundantly in particular. In addition, the fossil fuel resources
such as methane hydrate are discovered a lot in the Japanese sea near the shore, too.
Besides, technology receives international attention that carbon dioxide which is told to be
one of the causes of the global warming, be poured into the bottom of the deep sea.
It is important how you can build the base to be active in the ocean in the future. On theother hand, in recent years the big project that is going to make a big structure in the ocean
is suggested in various organization. Such as "Green Float" of Shimizu Corporation or
American Seasteading. In these days, various development is undergoing, being expectedthat a lot of changes would make useful for the future human life, distribution andproduction by constructing huge structure on the ocean. Here is the importance of the
OCEAN LAND Project.

2. Summary“OCEAN LAND” is based on “Ocean Republic” which is published on the magazine of “Funeno Kagaku”( Ship Engineering ) of March 1992 ( Vol.45). “Ocean Republic” mentions not only
a technological issue but also the political or economic issue. “OCEAN LAND” is the researchand development project focuses on the technical scientific side.

Ocean Republic

5https://oceanrepublic.org“OCEAN LAND” is all of the terms which are technologies, operations and engineering about
the mega float which is built from a few hundred meters length to a few kilo meters length
on the ocean.
1) Global Ocean Current And Mega Float
The movement of ocean current on the earth
is known to have complicated movement, but it
is largely moving clockwise in the northernhemisphere and counterclockwise around thesouthern hemisphere. If you build a large float(mega float) on the ocean, that float can goaround the ocean clockwise in the northernhemisphere and counterclockwise in thesouthern hemisphere. The mega float can beused for a variety of purposes.

Fig.2-2

Ocean Current(On the Google Map）

2) Lift Force Generator
However, as it is, there is a possibility that themega float will enter a watershed area where
typhoons and hurricanes are occurring, raise it
to a shallow area, or collide with the continent.
So we will construct multiple structures thatwill act as "sails" on the mega float. By theforce generated by the structure that plays therole of the sail, the mega float can move freely
offshore. This will enable you to avoid
Typhoons and Mega Float Course
Fig.2-3
typhoons and hurricanes' blowing waters and
VLSI = Mega Float
shallows. By obtaining this “Lift Force
Generator”*) equivalent to the sail, this mega float no longer needs
to go around the ocean.
By arranging many structures in the height direction on a huge
float, and by using the wind on the ocean, lift force like a sail will be
generated. This lift force allows the float to move offshore with
Fig.2-4 Sail Shipsome flexibility. The structure as a high-rise buildings can be used as aresidential space, an office space, a plant factory, a fish farm, etc.
Briefly, this float comes out in the OCEAN LAND has nothing different in principle from asailing ship moving on the ocean using the wind from the beginning of BC. Float body plays arole of ship, lift generating device like high-rise buildings plays a role of sail.
*) In this proposal, it is expressed as "lift" instead of "thrust". This is because textbook such as a sailing yacht, many
people describe it as "lift."6https://oceanrepublic.org

3) Atmospheric Flow And Mega Float
Under the technology of present, sailing yachts with advancedhydrodynamic performance can move upwind at an angle ofWind
about 45 degrees against the headwind. If the sailing yacht
moves in the windward direction, it goes upwind by tacking thedirection by 45 degrees at a time. When moving in the otherdirection, you can move by moderately changing the angle ofthe sail and the rudder of the ship. It is not able to be told how
Fig.2-5 Course of Sailing Yacht
much a mega float like OCEAN LAND can go upwind unless we
do experiment and research. However, it was possible for the sailing boat of the great
voyage age to move 90 degrees against the windward direction though it could not go
upwind. The ship at that time moved the ocean watching the wind direction and supported
the maritime trade in the discovery of the Americas and during the great voyage.
4) About Mooring Of The Mega Float
Can’t we moor and fix such a mega float on the ocean? Of course, if the mega float is close
to the land you can fix the mega float to the quay or the bottom sinker with ropes, wires,chains etc. However, if the wind blows strongly due to a storm or the tide becomes strong
due to a storm surge or the like, a great force is added to the rope, the wire, the chain, andthe possibility of breakage comes out. Moreover, it is difficult to moor and fix it at that
position no matter if it is several thousand meters in depth and hundreds of kilometers or
thousands of kilometers away from the land. The mooring line becomes too long, there is aproblem such as large tidal power is applied, the weight of the chain etc. becomes large andthe buoyancy becomes small.
5) Dynamic Positioning
There are also ways to stop at the same position on the ocean using equipment such as
propellers (dynamic positioning), but a lot of fuel and energy is needed to make mega floatstay.
3. Application Of OCEAN LAND
So, what kind of things will benefit us for humanity by building such a mega float on theocean?
1) Ocean Air Port, Ocean Port (Hub)When traveling a long distance offshore by airplane, you have to stack more fuel on board.
Therefore, it is possible to use OCEAN LAND as a mid-point (hub) offshore in the middle oftransportation as an airport. I will call this Ocean Airport for convenience. If you can refuelwith Ocean Airport in the middle of long journey, you do not have to load more fuel on your7https://oceanrepublic.org
flight when you leave and you can increase the load relatively. If fuel is supplied to the
Ocean Airport from a nearby undersea oilfield, the overall efficiency further increases.
Also, as for cargo ships going between harbors and ports between continents, if there is aplace (ocean port) where loads can be transferred to the ocean on the way, once anchoredat the ocean port, you can distribute cargo to the ground, freedom is given to the pattern oftransport for exporters and importers of cargo. We can make major changes to global
logistics and transport cargo faster and cheaper.

Normal air transportation

If you can refuel in the middle of the transportationroute you can increase the cargo that can be loaded。

is at the transportation intermediate
point. By integrating transportation at

and optimizing transshipment
transfers it is possible to improvetransportation cost performance as a
total.
Fig.3-3

Specifically, for example, we could arrange this OCEAN LAND in the North Pacific, the North
Atlantic, etc. and apply it as "Ocean Port". The North Pacific is connected to the North
Atlantic and the Arctic Ocean, it is currently only around two months in the summer, it is
known that the Arctic Ocean ice melts so that a general cargo ship can navigate. Passing from
Asia to Malacca Strait, through the Suez Canal, to the Mediterranean, to the European route,the route leading from Asia to the Europe through the Bering Strait is now drawing muchattention. It is expected to shorten the number of shipping days due to shorter route and to
reduce fuel. Therefore we will place this OCEAN LAND in the North Pacific and the North
Atlantic Ocean and operate as an Ocean Port. We will consolidate cargo from Asia andOceania once into this Ocean Port, where it will be transferred to a cargo ship dedicated to
the Arctic Ocean, which can navigate the Arctic Ocean, and will transport cargo to the Europe
through the Arctic Ocean. It is currently two months in summer, but it is expected to be
operated for a longer period of time in accordance with changes in the global environment.
Moreover, if the ship type of a special Arctic navigable cargo ship is developed, it is possible
to further extend the operation period.

Also, there is the way of an ocean port as a shipping port that can unload resources in
undeveloped areas such as Africa, South American continent, and even Antarctica. For
example, in Antarctica and elsewhere, even if resources useful for mankind are found, it canbe said that it is very difficult to build a shipping port on Antarctica. So, instead of creating ashipping port of full specification on the site, we will place an ocean port on the ocean a bit
far away. And we carry cargo (resource) from the small shipping port of the continent to theocean port of the ocean with a small boat. On the other hand, we can establish a facility
capable of anchoring large cargo ships at the Ocean Port. Between the continent and the
Ocean Port is a practical small ship and carries resources of the continent, refining or storing
the mining resources on the ocean port, processing it into cargo and loading it on a large
ship. Doing so eliminates the need tobuild large-scale harbor facilities etc.
on the continent being developed.
And if the resources of the continent
are exhausted and it is no longer
necessary to ship more cargo, you
Fig.3-5
can move the ocean port itself andmove to other required areas.
Delivery port in undeveloped
Investment to create large-scale port
area and OCEAN LAND
facilities on the continent from the
beginning will not be needed.

2) Ocean City As Resource Exploration
To the next, the most promising use is OCEAN LAND as a backward support city "Ocean City"
for mining and exploration of marine resources. In the future, if resources such as rare
metals, rare earths, methane hydrate, etc. of the seafloor are to be mined, it may benecessary to refine or stockpile them on the sea. This Ocean City can be operated as a citywith the purpose of backward support of submarine mines and mining bases. There, it ispossible to form a big city where not only those who work at submarine mines and mining
bases, but also people related to that project, people related to any institution / company
and their families live. In order to support the life of the city and people living there, it is also
possible to develop industries such as
aquaculture, agriculture, commerce andtourism on the ocean city. This Ocean City is
operated so that the lift force generator(LFG) works efficiently so that it goes backand forth between the limited seas of themining site.

Fig.3-8 OCEAN LAND
as Resource Exploration(Submergible Style)11https://oceanrepublic.org
3) OCEAN LAND As A Space Port
Furthermore, there is a simple use as an ocean city as an offshore living space. Recently,
various ideas for setting up a living space on the ocean are being announced. There areGreen Float of Shimizu Corporation and the Seasteading plan to create a living space in the
US offshore. (previous cited) Although each purpose is different, there is a point ofagreement in seeking living space on the ocean.
Marine structures appearing at Green float and Seasteading are very difficult to move freely
over the ocean. However, OCEAN LAND can be used as a living space on the ocean, and canalso move by using the wind. It is possible to correct the movement of position by tidal
current or wind etc.

4) Base For Space (Orbital Elevator)
In the future, the idea which not using a
rocket to get into outer space, but using
a vehicle that climbs a strong wire to thegeostationary orbit(GSO) of the earth
with a device called an “Space Elevator”.
Hanging down a wire-like material fromthe geostationary orbit(GSO) of theearth to the nearby of the equator on
the earth, so that we can go up from theearth to GSO or go down from GSO to
the earth on the vehicle sliding on thewire like elevator. In the past, it was said
that it was difficult to make such wires,Fig.3-9 Space Elevator

Fig.3-10 OCEAN LAND
for Space Elevator

but structural materials such as carbon nanotubes are said to be enough ideas even if there is
still considerable room for development.
This space elevator is basically required to place its landing point on the equator on theearth. If according this theory it will be located only in limited places on the earth, such as thedesert areas of Africa, and the outskirts of South America, or Singapore. However, if we use
12https://oceanrepublic.org
OCEAN LAND as the terminal of the space elevator, you can set up this landing point
offshore. In this case, the OCEAN LAND will move only within a certain range on the ocean.
It is said that it is more efficient to launch a satellite or space station near the equator of theearth in order to launch it into space orbit. You can use OCEANLAND as a launch vehicle forthat.
5) OCEAN LAND As Disaster Countermeasures

Fig.3-11 Structural section of an OCEAN LAND

Figure above shows structural section of an OCEAN LAND. OCEAN LAND is built having muchspace. Therefore, it is relatively easy to create a temporary housing facility if a large numberof people have lost their place due to a disaster. In the future, many disasters due toabnormal weather may occur due to the effects of large earthquakes and global warming. In
order to save many victims of such disasters, it is desirable to build houses on the ground.
However, political or administrative procedures in each country have tendency of becoming
complicated, and it will become difficult to provide housing immediately. On the other
hand ,OCEAN LAND is structurally available, so it is possible to prepare such a residence
relatively quickly.

13https://oceanrepublic.org
The figure shows acomparison of costs
for maintaining theliving environmentand damage at
disaster on land andin the OCEAN LAND.
OCEAN LAND is able
to navigate the ocean
freely, and disasters
free. Therefore, there
is no cost for disasterrecovery or disasterprevention cost as
shown at the top of
the figure. They are
not once at disaster.
They are needed forevery time at disasters.
Japan has experienced
major earthquakes suchas the Great HanshinAwaji Earthquake and
the Great East Japan
Earthquake over the
past 30 years, and in thenear future, major
damage is expectedfrom the Tokyo

maintenanceIn recent years, many
disasters have occurred not only in Japan but also around the world due to huge typhoons
and hurricanes caused by changes in the global environment. Considering the cost of
recovery to return to the previous state from the damage, OCEAN LAND is expected as analternative living environment for humankind in the future.

LAND cost comparison formula forliving environment maintenance14https://oceanrepublic.org

In addition, research has been
done to reduce the power oftyphoons on land or eliminate
typhoons themselves, and to
study artificial rainfall to reduce
drought damage, but it has not
yet been put to practical use.
In the case of OCEAN LAND,
typhoon damage can beprevented by deciding thecourse of OCEAN LAND in the
direction to avoid the typhoon.

decide the courseof OCEAN LAND in

can secure thenecessary fresh

Asteroids colliding with the Earth are now fairly accurate, allowing us to determine when
and where they will collide years or months later. With a few years or months to spare,
OCEAN LAND can move to the other side of the globe to minimize its damage.

6) For Island Nations That Are Losing
Their Land Due To Rising Sea Levels
In recent years, there are several
island states that are rising in sea level
and losing their land. In an island
nation that is only a few meters above
sea level, the land itself is almost lost.
We can use OCEAN LAND for such

countermeasures and artificial rainfall on
land and in OCEAN LAND

island states. For example, it is possible to travel
around the remaining 200 nautical miles of the land
carry people who moved from the mainland to the
OCEAN LAND for a semi-permanent tour of
the archipelago.

7) OCEAN LAND As An Organization That Supplies Oxygen To The Earth
In August 2019, it is reported that large-scale fires in Amazon of Brazil have occurred more
frequently than in the previous year. As you know, the Brazilian Amazon is said to be the“Lungs of the Earth” that supplies large amounts of oxygen, but the loss of the Amazon ’s
forested jungle has reduced the ability to supply oxygen to the Earth.
In OCEAN LAND, there is a plant factory in a LFG(high-rise buildings), and it is possible toplant plants on the flat place on OCEAN LAND. In the future, if hundreds or thousands of
OCEAN LANDs are born on Earth, it is possible to help supply such oxygen.
8) OCEAN LAND As A Development Base For Agriculture, Forestry And Fisheries
Development in agriculture, forestry and fisheries is also possible even on land. However,
OCEAN LAND will take advantage of the properties of the environment far away from theland, and in a good sense it will be possible to develop and improve Galapagos species thatare independent of land species.
The development of agriculture, forestry and fisheries can be considered as follows.
a) Research and development for complete aquaculture of tuna(maguro) and eels(unagi)b) Research and development of agriculture, forestry and fisheries species with highproduction volume in a small space
This technology will be needed for future space travel and space migration.

17https://oceanrepublic.org
If this technology is developed, it will be able to cope with the future food shortage, andit will be a technology that will allow space migrants in the distant future to beconsidered.
9) OCEAN LAND As A Global Pandemic / Infectious Disease Countermeasure
In December 2019, the new coronavirus (COVID-19) originating in Wuhan, China, spread
rapidly all over the world in 2020, and the Tokyo Olympic Games scheduled for 2020 were
postponed. It is a global disaster.
OCEAN LAND is at least tens of kilometers away from the adjacent ocean land by sea. If
mutual transportation is cut off, the spread of infection can be prevented. Of course, it ispossible to spread the infection to some extent by insects and migratory birds, but humanto-human transmission is much easier to control than on land.

10) Other Uses
Other possible uses are as follows.
a) Hydrogen production plant
A plant that produces hydrogen, the fuel of the futureb) Carbon dioxide compression storage plant
It is said that the increase in carbon dioxide on the earth is accelerating global warming.
So, the technology development (storage) to transfer and store the carbon dioxide to
the seabed and its plantc) Public ceremony center
There is also a shortage of graveyards on the land to mourn the dead. It can be used inany religion. It may be possible to have a ceremony center and an offshore burial place.
11) Scale Of OCEAN LAND And Its
Flexibility
The purpose of OCEAN LAND
maneuvering is depend on its scale.
OCEAN LAND must remain near alimited area as resource
development bases. For this reason,
small-sized ones with a small turn aresuitable. Big OCEAN LAND is suitablefor forestry and fisheries industry andresidential purposes.

and its flexibility.

Are there any measures against tsunami and other things? The 2011 East Japan Great
Earthquake Disaster caused Tohoku district to suffer great damage by tsunami exceeding18https://oceanrepublic.org
more than 20-30 meters in height. Will such a big tsunami wave hit OCEAN LAND? Thetsunami is known to gradually shallow the water depth, and the waves will rise and overlap
as the wave speed gradually slows down, and it becomes a mountain like a few tens ofmeters. In the East Japan Great Earthquake Disaster the fishing boats that escaped offshore
were never caught in the tsunami. As such, at the center of the ocean the tsunami has avery long wavelength, it is not such a big force as to destroy the structure of OCEAN LAND.
However, no matter what kind of measures are taken, it may be awaiting by disasters thathuman beings cannot infer. Considering the worst situation that OCEAN LAND's mega float
itself will sink into the ocean, we must take measures for it. We can use dome garden ordome stadium as life boats in OCEAN LAND. It is possible to create a system in which thedome automatically floats even if the inhabitants retreat to the dome and the ocean land is
submerged. OCEAN LAND has a harbor. Cargo ships carrying goods from the continent etc.
enter this port on a regularly. So, at all times, we can use those ships as life boats.

2) Method For Emergency Stop

document”8. Feasibility

Mega Float (VLSI)” shows
calculation detail, if there is
5m/s wind, OCEAN LAND canstop with in 600m and in one hourand half with make LFG as brake.
And here, we want to propose for
emergency stop.

Layout of
OCEAN LAND

Fig.4-3

OCEAN LAND has sea water large tanks in the higher place. They will be arranged around of
an OCEAN LAND.
By store sea water in those sea water tanks, we can use it for several purposes. For living
water, industrial water, agricultural water.
If the OCEAN LAND gets too close to shallow water or islands, etc., OCEAN LAND will stop by
temporarily opening the sluice gate in the direction of the obstacle. We can also change thedirection of the water coming out of the sluice to avoid obstacles.

Fig.4-4

Sea Water Tanks and OCEAN LAND and obstacle (Island)

5. Operation System Of OCEAN LAND
1) How To Control OCEAN LAND
The course of OCEAN LAND is based on learning the past weather data by AI (Artificial
Intelligence) and judging from what the current weather data is, what kind of weather sea
area to go to as OCEAN LAND has the greatest gain, that is, the merit. Then operate each lift
generator.

20https://oceanrepublic.org

Fig 5-1

The way to control an OCEAN LAND

2) Control Method As A Group Of OCEAN LAND
Safety and utility will be increased by sailing over the ocean as a group with multiple OCEAN
LANDs separated by several tens of kilograms at a time.
For example, suppose there were six OCEAN LANDs as shown. Each of them keeps theirposition in the ocean while moving in the same direction taking a safe distance of tens ofkilometers. Each OCEAN LAND is devised to increase utilization efficiency by sharing the mainrole. The port and airport can be used one by one in six OCEAN LANDs and other OCEAN
LANDs for other purposes. One OCEAN LAND is aquaculture center, One OCEAN LAND is anagricultural center and each OCEAN LAND can be divided into different roles for efficient
operation.
Also, by navigating the ocean in an array likethe archipelago like this, safety increases.
Although it should not happen, for example,
when there is a fear of collapse and sinking
in one OCEAN LAND, the residents mustevacuate from that OCEAN LAND. If OCEAN
LANDs are being operated like this as anarchipelago, all the residence can move
instantly to the surrounding other OCEAN
LAND. It will ensure the safety of theresidents of each OCEAN LAND.
Fig.5-2 OCEAN LAND as an Archipelago

6. Construction Method And Maintaining Mega Float
1) How To Build Lift Force Generator
Describing the construction method. In order to build a huge float on the ocean, you cangradually connect a caisson that is split and constructed. The problem is how to build a highrise building that will be a lift generator on the mega float. The higher the height of a highrise building, the greater the load on the ground becomes. Therefore, by canceling thebuilding in the height direction by the buoyancy of the float in the seawater, we make theshear force in the vertical direction with the float on the sea surface approach zero. You cangradually build a LFG(Lift force generator: high-rise building) so that the load from above and21

https://oceanrepublic.org
the buoyancy below the water surface balance up and down in the place where the lift
generating device opened on the float is made.

Fig.6-1 Construction method of the high-rise building

In addition, as we will discuss later, we believe that in the future we should do research tobuild marine microorganisms rather than human creation of mega floats themselves in
OCEAN LAND. Artificial structures like OCEAN LAND have naturally a lifetime and require
maintenance by humans. If you made a mega float using something like iron or concrete. Its
lifetime is assumed to be one hundred years. A simple calculation, from the time of
construction, every year one hundredth amount of the large float will be rebuilt, necessary
for repair and maintenance. It is hard to build a mega float, but maintenance also costs a lotof expenses, physical quantity and cost. Can we make this using something like a marine
microorganism? I think that such research should be done. If a mega float has some cracks inthe main structure, for example. If it made of iron it is necessary to repair it with welding etc.
If it is made of concrete, measures such as filling up cracks are necessary. On the other hand,
it is known that in the human body, for example, if the bone does not completely fracture,but cracks are present, it is possible to self-heal to a certain extent without going through adoctor and treating it or performing surgery. I think that it is necessary to research whether
the large float itself can be built by using marine microorganisms or not. Also it can be
maintained or not.
2) How To Build Up An OCEAN LANDOCEAN LAND will not be built offshore from the beginning, but gradually build caisson near
the land, and build lift generators (high-rise buildings), after that, complete as close to theland as possible, and leave the land.

3) Building Up By Biomechanical Method
The latter section of the document ” 10. Typical Research Themes for OCEAN LAND Project“Research about Construction Method for Large Scale Structure” I will describe, There is amethod that uses marine microorganisms to build the mega float that is the foundation of
OCEAN LAND, rather than using an engineering method.

https://oceanrepublic.org

Fig.6-3-3 After building up a mega float,
other buildings such as LFG(high-risebuildings)will be made.

4) Build Up LFG On A Big Iceberg
If it is an OCEAN LAND operated near the ice sea, we can cut out the iceberg and use it asan OCEAN LAND.

Fig.6-4-1,2 The iceberg is processed to create an OCEAN LAND base and LFG (high-rise buildings) will be
installed. If it is in an ice sea, it is possible to travel without melting the OCEAN LAND. It is also possible toreinforce and spread the foundation by stretching the refrigerant pipe. Since the volume of icebergs andice blocks below the surface of the water is larger than that above the surface of the water, theresistance due to seawater increases and the movement becomes slow.

5) How To Maintain A Mega Float And Replace A Caisson
Here how to maintain the Mega Float after building the Mega Float will be described,
which is the foundation of OCEAN LAND.
Assuming that the life of the Mega Float is 100 years, 100 years later, rather thanrebuilding a new Mega Float, if each caisson of the Mega Float is replaced one after another,
the OCEAN LAND will be possible to operate the land without stopping functioning permanently. How to replace the caisson, which is a part of the mega float, hear how to
replace the caisson which seems to be the most difficult under the skyscraper will be
explained with figures,24https://oceanrepublic.org

Fig. 6-5-1
On the left is a cross section of OCEANLAND (top) and a plan view of the caisson(bottom).

Fig. 6-5-2
Normally, OCEAN LAND stores seawaterballast in the caisson section so that theload of superstructures such as high-risebuildings and the buoyancy of the caisson
should be balanced.

25https://oceanrepublic.org

Fig. 6-5-3
First, replace the caisson directly under
the skyscraper with a new one. Therefore,
the seawater ballast water is adjusted togenerate more buoyancy than usual in the
caisson surrounding the caisson directly
under the center of the skyscraper. After
that, using RWSV(Robot Working
Submergible Vessel) the caisson under
the skyscrapers will be moved out of the
OCEAN LAND.

Fig. 6-5-4
Using RWSV,replace the caisson directly
under the skyscraper with a new one.

Fig. 6-5-5
Next, to keep balance between load of
the skyscraper and the buoyancy of thecaisson ballast water should be loaded in
the caisson. After that, using RWSV thecaisson will be moved out of the OCEAN
LAND.

Replace not only caissons underskyscrapers, but other caissons as well.

7. Lift Force Generator
The Lift Force Generator (LFG) plays a very important role in the OCEAN LAND project. In the
Ocean Republic / OCEAN LAND, mega float is called SI (Sailing Island) or VLSI (Very Large
Sailing Island) for convenience. The lift generator is mounted perpendicular to the sea
surface on this mega float. From the wind blowing on the ocean it is possible to generate alift, or thrust, laterally of the mega float.
Here I will present some ideas for such a lift generator (LFG).
Regarding patent applications for these devices, there are some that have been submitted
and some have not been submitted. The "Ocean Republic" was announced in autumn 1991
at the in-house research presentation by electronic equipment manufacturer. The following
year the paper was published in the “Fune no Kagaku”(Science of Ship) in March 1992. After27https://oceanrepublic.org
that, I filed a number of related patent applications, but since the sponsor was an electronicequipment maker, many patent applications were not allowed due to the management
policy of the company, and only a few special cases were submitted.
In technology development, obtaining a patent is indispensable, but the expiration date of
the patent is 20 years, and in the case of technology development that takes many years until
completion, such as OCEAN LAND, many patents are filed It can be said that filing
applications is disadvantageous from the patent strategy. I also think that it is important tofirst determine what kind of method and technology are necessary for patent acquisition andto determine what kind of technology to apply as a patent during research and development.
The lift force generator(LFG) is the largest possibility as a technical patent among OCEAN
LAND. The idea as a lift force generator which I have now is roughly as follows.

1) Airfoil Lift Force Generator With 3 Or 4 Divided Buildings

Fig.7-1

Fig.7-2

This is a combination of moving parts having two or three cross sectional shapes in the front
and back centered on a structure with a circular cross section in order to bring the sectional
shape of a high-rise building closer to the aerofoil shape. Each structure has a structure thatcan move in the circumferential direction relative to the fixed center cylinder so that lift canbe efficiently generated from the wind. It is a mechanism to obtain maximum efficiency liftby moving this divided part.

28

https://oceanrepublic.org
2) Symmetry Airfoil Lift Force Generator
This is a construction of a cross-sectional shape of a high-rise building as a lift force
generating device as a symmetrical airfoil, and the high-rise building itself is formed so thatthe lift force occurs at right angles to the wind direction by adjusting the angle with respect
to the wind direction .

Fig.7-3

3) Lift Force Generator With

Flexible WallA high-rise building is constructed as a building with a circular cross section and on theoutside it is provided with an exterior wall close to the airfoil made of a flexible material. This
outer wall is made to move freely around a high-rise building and the shape of its outer wall
can be transformed into a wing shape by the hydraulic cylinder as a whole. In this way it istrying to obtain maximum and optimum lift.

Fig.7-429https://oceanrepublic.org
4) Lift Force Generator With Porous WallThis is round sectional structure by making a series of holes through on the outer wall of ahigh-rise building with a fixed round cross section. By controlling the air flowing through theouter wall by closing or opening also volume, speed of air, we can get the lift by making
virtual wing form.

Fig.7-5

Fig.7-6

5) Lift Force Generator With Rotatable Wall
It has a cylindrical outer wall that can be rotated around a high-rise building. By changing thedirection of the movable flap on this outer wall, the direction and strength of the rotation of
the outer wall can be changed. Lift will be generated by Magnus effect by this rotating outerwall.

Fig.7-7

Fig.7-830

https://oceanrepublic.org
6) Lift Force Generator With Auto Gyro Turbine
The auto gyrocopter is a vehicle that rotates the upper rotor by the flow of air from thedirection of travel to obtain lift. I filed several patents for applying this auto gyro to ships on
the 1980's. We can apply the auto gyroscope attached to this ship to OCEAN LAND of thiscase and obtain lift for changing course.

Fig.7-9 Auto gyrocopter &Auto gyro ship
The application of this auto gyro toships has the following features.
a) It hardly hinders the visibilityof the bridge of the ship.
b) If not used, the propeller
blades can be folded so as not
to disturb the propulsive force.
c) Auto gyro propellers can beused as wind power
generators when there is no
direct need to produce thrust,such as in tailwind mode orwhen harbored mooring.
a), b) If this auto gyro propeller
can be unitized, it is possible toinstall the unit on the existingship without developing a newship type of the wind propulsion
ship and to reconstruct it into
an energy-saving vessel with asimple construction.

Fig.7-10

Ship with Auto Gyro Propellers

vessels can be converted to energy-saving vessels
without developing a special ship form.

The image above is a composite image of Ocean City for marine capital development which
installed this auto gyro propeller.
7) The Way To Combine Multiple Lift Force Generators
This is a method to control OCEAN LAND
by the thrust of the entire lift generator.
Fig7-13 shows an example with two lift
generators on a circular OCEAN LAND tounderstand easily. The lift generator isinstalled along a hole made in OCEANLAND and floats in seawater. In the caseof this figure, the lift generating device
built on the floating foundation isconstructed so that the straight part andthe arc part face each other, and whensubjected to wind as shown in the figure,generates lift in opposite directions.
Therefore, the effect of the wind isFig.7-13
neutral, and the wind is swept away. On
the other hand, the floating foundation
can be changed in various directions withrespect to the wind by the drive unit
installed on OCEAN LAND. Fig.7-14 showsthat when the force is generated in the
direction perpendicular to the wind byaligning the directions of the lift generators, Fig.7-15 changes the direction of the lift
generator so that the rotational force is generated.

Fig.7-14

Fig.7-15

8) Method Of Using Tidal Flow
It is assumed that OCEAN LAND uses wind as an energy source for movement, but it is also
possible to use VLSI with tidal flow for movement.
For example, suppose there is a VLSI as
shown in figure. Under the water surface, the
Fin
Tidal
wing type airfoil structure (huge fin) as( Under Sea Surface)
Flow
shown in the figure extends in the depth
VLSI
direction of the ocean. When this VLSI
receives a tidal current from the left
Lift
direction in the figure, the downward lift
Force
force of the figure works on the wing typefins, and the force moving downward in the
figure as a whole acts on the VLSI.
Fig.7-16
By using this tidal power as well as Coriolis force, it is also possible to trap the VLSI at the part
where the ocean current circulates. For example, suppose there is a VLSI at the part where
the ocean current circulates as shown in figure. Let Vt be the speed of the current at thistime, and Vv the speed of VLSI. The VLSI
travels in the same direction as the tidal
current while flowing to the tide current at
a speed slower than this Vt. Vt> Vv will beobtained. The speed difference Vt - Vv
becomes the velocity component acting on
the fins below the surface of the VLSI,
creating a force to move the VLSI in theFig.7-17
direction of the arrow in the figure.
This force works as long as there is an ocean current. Theoretically, the VLSI stops (almost
does not move) to the center part where this ocean current finally circulates. Therefore, if
there are no other large floating bodies in the vicinity, this VLSI will be able to stay semipermanently on the spot without worry of colliding with continents, islands and so on.

33

https://oceanrepublic.org

There are many parts of the Eartharound which the ocean current
circulates, so it is possible to apply tosuch a place.
Also, if you turn the fin below thewater surface in the opposite
Fig.7-18
direction as shown in figure, theopposite force will work, and if you
turn each one in the reverse direction as shown in figure, you can also rotate the VLSI.

8. Feasibility Calculation
Here I will conduct an initial study of whether the lift of the high-rise building built on mega
float (VLSI) can control the course of mega float in OCEAN LAND. As the contents ofconsideration 1) How fast can you move in the "lateral direction" with respect to the windblowing direction? 2) If an obstacle is found forward, issue a stop order calculate how muchtime and distance you can stop at two distances?
1) Cruise Condition Speed Of A Mega Float (VLSI)
Regarding the position control of the mega float (VLSI) in the Ocean Republic / OCEAN
LAND, the following conditions are required.
To have some degree of control possibility by the action of wind and lift force generator(high-rise buildings) for the purpose of avoiding obstacles such as typhoons, reefs andislands.
In this document I will consider the underlined part above.
Suppose now that a square VLSI with a side length of 1 km,
as shown in figure, receives 5 m / s wind from the right
direction in the figure. Calculate how much this VLSI canmove in the right direction of the wind (upward direction in
the figure) by the wind. There are 10 Lift Force Generators(high-rise buildings) in total. The draft of the float is
supposed to be 10 m. Since the total weight is unknown, we
calculate it as a temporary value, but we will ask how muchthe draft will change depending on the weight of the highrise buildings.
Taisei's(General Contractor) website says that the total
weight of Shinjuku Center Building (height 220 m) is
300,000 metric tons. Since the height of the high-risebuilding to be studied now is 100 m in height, we estimate
Fig. 8-1 Shinjuku Center
totally 150,000 tons in total and 1.5 million tons in 10 bodies.
Building
Because this will sink the 1 kilometer mega float, if we set the
specific gravity of seawater as 1, it will be 1,500,000 / (1000 x 1000) = 1.5, so the draft
difference will be 1.5 m by the high-rise buildings as a whole. In addition to that, the float
has weight due to the structure that supports the float itself, what is built on the float,
weight due to trees and landscaping etc. However, it is said that it is a quotient enoughestimate even if the draft is estimated at 10m.

The strength of the lift acting on the airfoil shape can be obtained by the following
formula. Here I assume that force works ideally. If this L is viewed as an upward force acting
on a lift generating device (high-rise building) for one body,

L=

Vw: Wind Velocity(5 m/s )SL: Wing Area（40m x 100m =4000m2 )
CL: Lift coefficient（Assumed 0.6）

By calculation, it becomes 39000 kgm/ s2 per Lift Generator (high-rise building)If there are ten high-rise buildings, it will be 390,000 kgm/s2. You can see that this force hits
the wind direction perpendicular direction (upward direction in the figure).
On the other hand, the resistance D1 due to the water flow corresponding to the projectedarea of the submerged part of the VLSI in the direction of travel is obtained by the following
equation (2). Also, a mega float of 1 km square gives rise to frictional resistance. The
frictional resistance D2 is given by the following equation (3). Since the sum of these D1 andD2 will compete with the force of the lift generator of 10 bodies obtained in (1), you cansolve this equation and find the speed of VLSI.

If you calculate the amount of VLSI movement per day, you can get

0.215m/s x 3600sec. x 24h = 18.6km. . . . . . .(7)In this calculation, it was found that the distance that VLSI can travel in the direction
perpendicular to the wind direction per day is 18.6 km.
The calculation above calculates the draft of the mega float as 10 m, but it is actually
expected to be smaller than that. Calculate the same calculation as above, if the draft ofthe mega float is 5 m, calculate the case of 20 m respectively, the movable amount in one
day when the draft is 5 m is 25.1 km, and the movable amount in one day when the draft is
20 m is It will be 13.4 km. As the draft becomes deep, the resistance of the water increases,
and the movable amount becomes smaller. Here D1 >> D2 then, you may neglect D2forthe calculation.
Fig.8-3 Mega Float Draft and Movable Distance of the Day

What is the speed of the tidal current in the Pacific Ocean? From Asakura Shoten ” Ocean
Development Technology Handbook” It is written that the flow velocity of the northequatorial current is 0.25 m/s to 0.50 m/s. VLSI speed does not exceed this speed, andassuming that the VLSI is running at a speed of 0.20 m/s, balanced with ocean current,
resistance of air resistance and water, the VLSI goes from directly in the direction of travel

Fig.8-438https://oceanrepublic.org
For the blowing wind, it is possible to control to move the VLSI at approximately 45 °oblique angle and to avoid obstacles.
In fact how fast is the wind blowing in the Pacific and the Atlantic Ocean? If you refer to the
JAMSTEC website, you can see that winds at least 5 m/s on average are blowing almost atsea. Therefore, as you can see from the above calculation, the range that VLSI can becontrolled will be considerably wider than the previous calculation.
2) Ability Of Stop Of A Mega Float (VLSI)
According to the calculation of 1), VLSI found that it is possible to change the course in the
direction perpendicular to the direction of travel, about 20 km per day if the wind of about
5 m/s is constantly a day .
Next, we will examine the approximate examination of how much time and distance arenecessary to apply braking and stop from the state where the movement is continuing at
the speed considered in summary consideration 1).
It is assumed that the VLSI continues to move upward in the drawing at the speed shown inthe summary consideration 1) and wind at 5 m/s is blowing from the horizontal direction.
At that time, after we have issued a stop order, we will reversing the lift generator, howlong it will take to brake, and calculate approximate how far you will travel the distance.

Assuming that all the forces acting on the lift generator calculated in the outline 1) can beused for braking, it is possible to use 390000 kgm/s2 of lift generator ( High-Rise Building ).
Assuming that the mass of the VLSI is obtained from the drainage volume and is 10 m ×1000 m × 1000 m × 1.025 = 1.025 × 107 × 103 Kg
From this equation, the acceleration a is 38 × 10 -6 m/s2
The time until the VLSI speed becomes 0 can be obtained by the following formula.

V: Velocity( 0.215 m/s )V = at…….(9)

a: Acceleration( 38 x 10-6 m/s2 )t : Time ( sec )From the formula above, t is required to be 5645 sec. It will take about an hour and a half

The travel distance and time can be said to be the same as the time and distance required
from stop to constant speed movement. The calculation above is calculated assuming that
only wind force is used for braking. However, in reality there is water resistance against
VLSI speed, the braking distance will be even smaller.
Since the calculation here uses VLSI of 1 km x 1 km as the standard of calculation, we willconsider only the numerical order. Actually, these figures will change depending on the
shape and size of the VLSI, how many and the size of the high-rise building that is the lift
generator will be.
9. Trial Design For OCEAN LAND
1) Outline Of The General Structure
Here is a layout diagram of OCEAN LAND with the function of Ocean Port. This is only an
example.
It becomes an island with the function of the city as a whole. It consists of ports, airports,
residence facilities, offices, commercial areas, agricultural areas (in high-rise buildings), andso on. Also on the outermost side is a breakwater that protects the island from the waves.

Fig.9-1 Layout of OCEAN LAND

41

https://oceanrepublic.org

The section is as shown below. The upper floors of high-rise buildings are arranged withorchards, vegetable farms and ranch. Farms and ranches do not require the work necessary
for human living, interior necessary for living environment, etc. Currently I think that theplace where people live will become the lower floor considering oscillation and safety.

Fig.9-2 Section of OCEAN LAND

2) Power Supply
The power of OCEAN LAND is mainly supplied by the wave power generator attached to thesurrounding breakwater. Wave power generation is being developed by the UK, but there is
still room for development in terms of cost performance. It is also been considered
operating hundreds of air turbine generators using the pressure difference caused bywaves between hundreds of air chambers in the caisson. It is also possible to deploy
photovoltaic(solar) panels on the outer walls of high-rise buildings.

Fig.9-3 Power Plant of OCEAN LAND

42

https://oceanrepublic.org
3) Fresh Water Supply
Fresh water used in OCEAN LAND is obtained by desalinating seawater. There is almost no
problem with seawater desalination technology because it is an established technology.
However what do you do if you live in OCEAN LAND and the animals and plants are
running out of fresh water? As mentioned before, OCEAN LAND trains AI (Artificial
Intelligence) with all the weather data in past, and calculates from which weather data thedirection of OCEAN LAND's course will give the highest gain. Provides support to lift
generators, etc. Therefore, when there is a shortage of water, we will take the course in the
direction of the highest probability of rainfall, secure sufficient rainfall, and secure fresh
water by collecting and purifying the rainfall that has fallen over all of the OCEAN LAND.
There are studies that try to eliminate the water shortage by artificial rainfall, but in OCEANLAND it is possible to navigate while selecting the required weather.
4) Characteristic Of Whole Structure
OCEAN LAND has a special structure called mega float and a complex of a high-rise buildingthat is a lift generator. Specific structural characteristics are determined as research
progresses, but the structural characteristics that we are currently considering are mainly
high-rise buildings and rigid structures around them, while the flat parts of the mega float
are flexible structures that can absorb wave energy.

Fig.9-4 Structure Properties43https://oceanrepublic.org
5) OCEAN LAND Structure Having A Center Board
Sailing yachts have a structure in which a board called a “center board” is inserted into thevertical water from the surface of the water to prevent the sailing yacht from being flowed
away by the wind. As well as, it is necessary for the OCEAN LAND to have a larger projectedarea of the grid cross section parallel to the traveling direction than the vertical section
perpendicular to the traveling direction of the OCEAN LAND. This space can be assigned toutilities or fuel tanks.

Fig.9-5 Center board of a sailing yacht

Fig.9-6 Center board of an OCEAN LAND

6) LFG ( High-Rise Building ) Structure
LFG ( Lift Force Generators: high-risebuildings) are indispensable for Ocean
Land, but large forces and bending
moments are generated by the wind in
the lateral direction of the high-risebuildings. This measure is necessary. The
following figure shows how to deal with it.

LFG( High-Rise Building ) by wind44https://oceanrepublic.org

and moment generated by the wind witha flexible structural member.
The higher floors of high-rise buildings areallocated to vegetable factories andorchards, so people are not affected by
the movement of high-rise buildings.

In this case, the lower part of the wire will
be movable around the building alongwith the wing shape deformation.
A fairing is attached around the wire toprevent wind noise and wind force.

10. Typical Research Themes For OCEAN LAND Project
The main research topics related to the OCEAN LAND program are as follows.
1) Trial Design Of SI(Sailing Island), VLSI(Very Large Sailing Island)
By designing a trial design, how much performance is required for mega float VLSI, how muchquantity is needed, what kind of method can be considered for construction, etc. are subjects
to be studied. We also need research to understand the structural characteristics of mega
float.
2) Research About LFG ( Lift Force Generator ) System
It will be the main research content in research and development of OCEAN LAND. It isnecessary to research and develop and investigate various methods, methods andperformance of lift generator.
3) Research About Construction Method For Large Scale Structure
We will study whether mega float can be built using marine microorganisms etc. rather
than using artificial structures. The goal is to build maintenance-free structures on the sea.
4) Scale Experiment In The Ocean
It is a demonstrative experiment
proving that mega float by the lift
generator which is basic technology of
the OCEAN LAND plan is controllable.
We will change various lift generator
and operate in actual waters, we will
acquire data such as ocean current,
wind direction, wind power, tidal
current, speed and direction of theexperiment vessel.
Fig.10-1 Demonstrative Experiment ( Image )11. Goal Of Research & Development

We will describe what kind of criteria should be the results of research and development.
d) Common Interests Of Mankind
To be able to explain that the human race of the world will lead to a common profit thatcan be convinced.
46

https://oceanrepublic.orgb) Technical Aspect
Explain that it can be realized technically and experimentally, numerical and logical backing.
c) Environmental Protection
It is a technology that does not destroy the global environment, but rather can contributeto preservation of the global environment.
12. OCEAN LAND From Planning To Construction
1) OCEAN LAND Model Selection And Research
The first thing to do before planning and building OCEAN LAND is selecting and studying
existing model islands. For example, Tanegashima has a Japanese space rocket launch base. Japan's
cutting-edge technology and human resources are gathered. On the other hand, there are people
who run agriculture, forestry and fisheries on the island, and their families, that is, children andelderly people, so there will be elementary, junior high and high schools on the island, and facilities
such as hospitals. In addition, various occupations such as commerce, industry, tourism,
transportation anddistribution industry, and life
are mixed to form
Tanegashima. In order tobuild OCEAN LAND, not only
engineering solutions but
also research, development
and design of what kind ofsociety must be realized in
OCEAN LAND must be
carried out.

13. OCEAN LAND And Natural Environment
Isn't there a big impact on the natural environment by creating a huge structure like OCEAN
LAND?. The idea of "Protecting the Natural Environment" is very important. However, nature is
not always calm and quiet. We must also consider the possibility of extinction of animals andplants due to pyroclastic flows and ash fall caused by volcanic explosions once every several
hundred years, tsunamis caused by huge earthquakes, or collisions of asteroids with the earth,which are said to occur once every tens of thousands of years. It is said that if an asteroid collides
with the Earth, dozens of percent of the species on the earth will be extinct. If humans are awarethat they are at the top of the entire life pyramid on Earth, then they have obligation andresponsibility to develop counter measures for the survival of them, plants, animals, and all living
things.
14. OCEAN LAND And SDGs
The Sustainable Development Goals(SDGs) or Global Goals are a collection of
17 interlinked global goals designed to bea "blueprint to achieve a better and moresustainable future for all.(SDGs fromwikipedia) OCEAN LAND , to achieve
the Goal 11) "Sustainable cities andcommunities”, Goal 13) Climate action,
Goal 14)Specific measures against climatechange, and Goal 14) Life below water inmain. We will continue to research anddevelop for this purpose.

15. Significance And Challenges Of OCEAN LAND
1) SignificanceI want to give another significance of
OCEAN LAND as well as the preface of thisdocument.
When we consider the “physical age”, we
can say that the history of mankind so far
is centered on land.
There are solids, liquids, and gases in thematerial, as well as the solid era centeredon land, the liquid era centered on theocean, and finally the human beings will
emigrate to space colonies, the moon and Mars. I think there will be gas era.
Above the ocean land is a semi-closed
space isolated from the land by theFig.15-1 Physical age concept
ocean. In the future, in order for people
to go into outer space in the gas age, they will move together with animals and plants in thespacecraft, and will move while repeating the food chain in the spacecraft.
I think the liquid age can be said to be the time to prepare for the coming gas age.
In addition, as mentioned before, when the environment of the people living near the coastor on the islands is threatened due to rising sea levels on the whole earth, it becomes acandidate for migration to such people. OCEAN LAND can be said to be a Noah's Ark in the
21st century because it can avoid tsunami disasters and does not cause flood disasters.
2) Challenges
There are various challenges in realizing OCEAN LAND. The largest of them is theuniversality of the whole organism, " Except for some insects, fish and birds, all humans andall living things tend to select the place where they have survived and being grew up fromgeneration to generation as the place of survival and breeding for themselves and for
future generations." It is related to the law. Since the birth of the earth, all living things on
the earth have been evolving repeatedly while applying to the environment, and finally thepresent place is the optimal place for survival and breeding.
Most people are born on land. People grow up there in their childhood, in relation totheir parents, grandparents and siblings. During that time, they grow up while being
familiar with the scenery, the four seasons, customs, and culture of the area, and their
attachment to the area is born from festivals, local events, and food products.
And when it's time to grow up and become independent, it's time to choose to continue
living in the area or move to another land. While you may choose to live in a land otherthan the one you were born in, such as because of a job, some people may continue to live
there because of your relationships with your parents and family.
Even if OCEAN LAND has a disaster-resistant living environment and strengths, it may not
be selected as a residence, and even if it is land-based land that is often exposed todisasters, it has a strong attachment to the land. In some cases, you may choose to live onland, in your own hometown.

In order to build an OCEAN LAND and make it an environment where many people canlive, it is not just a matter of the length of the living environment, but something that canbe chosen more than that.
Recently, the story ofMars migration has
become more specific.
However, migrating toMars is a harshenvironment that is
incomparable to theglobal environment, and isprobably a one-way ticket
trip. However, somepeople are opting to moveto Mars, albeit in the
distant future.

16. Flight Simulator “EZ FLIGHT”
I will explain "EZ FLIGHT".
( EZ FLIGHT can be downloaded free from http://oceanrepublic.org/simulator/. )By opening the website (http://oceanrepublic.org), we received opinions from various
people. One opinion among them "There is an opinion that I think that it will be easier tounderstand if there are things that are easier to understand, such as models, although it canbe understood as a concept." That's why Flight Simulator "EZ FLIGHT" was created. By
software to fly over the OCEAN LAND in a virtual 3D flight simulator, or OCEAN LAND is whatkind of things, to understand, I think you can feel.
