Redefining Undersea Warfare Through High-Density Bionic Swarms

For decades, naval doctrine has been obsessed with size. We build multi-billion-dollar aircraft carriers and giant, city-sized nuclear submarines packed with over a hundred crew members. But in modern warfare, concentrating all your capital into a few massive targets is a massive strategic mistake. If a crisis erupts in a shallow, high-threat choke point like the Strait of Hormuz, these multi-billion-dollar assets become liabilities—too expensive to lose, and too large to hide.

We don't need giant submarines anymore. Look at modern fighter jets—advanced combat aircraft controlled by a single pilot. If advanced automation and artificial intelligence can allow one person to fight in three dimensions at supersonic speeds, it can absolutely allow a single operator to command an ultra-compact, highly automated submarine.

By scaling down the vessel to the physical proportions of a mature sperm whale—roughly 14.5 meters long and 42 metric tons—we can pivot away from force concentration and completely saturate the global battlespace with a rapidly deployable swarm of bionic submarines.

Bionic Propulsion: Flying through the Water

Traditional submarines are loud because they rely on rotating machinery: massive steam turbines, complex reduction gears, and spinning propellers that slice through the water and create a distinct acoustic signature.

This architecture throws that out entirely. Instead of a spinning screw, this submarine uses a bionic vertical tail fluke that pushes water cleanly backward, mimicking the fluid dynamics of a dolphin or a whale.

The drivetrain is completely gearless. Power is routed directly into an electro-hydraulic servo pump that pressurizes a closed-loop fluid network up to 50 MPa. This high-pressure fluid directly actuates the flexible joints of the tail. By adjusting the stroke frequency automatically through an AI flight core, the sub achieves an incredibly quiet, highly maneuverable propulsion profile that is completely buried beneath the ambient noise floor of commercial shipping lanes. Furthermore, because it bypasses the efficiency taxes of traditional spinning machinery, the net system efficiency jumps to an estimated 33–36%, extracting far more propulsive force out of every kilowatt.

Turning Liabilities into Assets: Shielding as Ballast

In standard submarine design, matching your displacement to achieve neutral buoyancy requires carrying thousands of kilograms of dead weight as ballast. At the same time, keeping a human crew safe requires an intensely heavy, dense armor shell to withstand close-range underwater explosion shockwaves.

This design combines these two engineering challenges into a single elegant solution: parasitic mass consolidation. The single-operator command cockpit sits inside the exact geometric center of the hull, completely encased in a 20-centimeter-thick titanium-tungsten matrix jacket.

The Dual Purpose: This hyper-dense shell provides the exact fixed ballast mass required to make the 42-ton hull sink, while simultaneously acting as an impenetrable kinetic mirror.

The Blast Protection: Because tungsten has an immense acoustic impedance mismatch compared to seawater, the pressure wave from a nearby underwater explosion is mostly reflected backward into the ocean rather than penetrating the hull. The entire submarine reacts as a single rigid body, absorbing the momentum through localized movement while internal damped suspension protects the pilot from the shock.

Zero-Signature Passivation and the "Kangaroo" Bay

Clearing a mined waterway like the Strait of Hormuz is traditionally slow and highly visible. This biosubmarine changes the geometry of mine clearance by operating completely underwater through a specialized ventral (belly) payload bay.

The sub carries compact, fish-like micro-ROVs that utilize flexible pectoral flaps and an oscillating tail fin instead of spinning electric motors. This bionic layout prevents the ROV from fouling its trailing 100-meter electro-optical power tether.

The main submarine glides safely in the deeper, high-pressure water layers underneath the minefield, while the lightweight ROV swims upward to plant targeted demolition charges. If a mine detonates prematurely, the deep water acts as a hydrostatic cushion, forcing the explosive energy upward toward the air-water surface and keeping the primary hull safe.

Even firing weapons is optimized to prevent detection. The sub utilizes specialized sleeve-and-core hydrostatic torpedoes. When a weapon is launched, only the inner kinetic core swims out. Seawater passively backfills the outer stationary sleeve at the exact millisecond the core moves. The submarine suffers zero net displacement shift, zero buoyancy change, and zero mechanical valve noise—maintaining its perfect horizontal trim without breaking silence.

Global Logistical Mobility

The true strength of a 42-ton bionic submarine is that it completely breaks free from permanent naval port dependencies. Because of its compact physical footprint, it shifts underwater warfare into a global airborne logistics framework:

Air Deployment: The entire sub conforms to standard military cargo bays. A single C-17 can drop a fully operational unit via low-altitude parachute extraction directly into a distant maritime choke point within hours.

Consistent Hydrostatic Ballast: By utilizing a high-capacity solid-state battery bank to power the electro-hydraulic drivetrain, the vehicle avoids the weight shifts common to fuel-burning architectures. As electrons drain, the mass and center of gravity remain completely flat.

Submerged Wireless Recharging: To maintain complete operational stealth, the submarine never needs to surface. It utilizes submerged inductive power transfer panels molded directly into its skin. The sub can glide into an automated harbor slipway, a wet dock lowered beneath a standard commercial cargo ship, or onto a dedicated docking cradle deployed by a larger nuclear-driven mothership to completely top off its cells wirelessly.

Conclusion

Investing billions into massive, single-point-of-failure hulls that cannot be safely risked in shallow littoral waters is a doctrine of the past. By combining advanced AI flight automation, direct fluid power transmission, and a globally deployable bionic architecture, we can shift naval power away from giant targets and toward an invisible, highly resilient, and unstoppable underwater grid.

Mega-Project Logistics in the Suez Canal and Beyond

Traditional civil engineering methods for mega-scale canal expansion are bottlenecked by mechanical tool wear, atmospheric heat constraints, and sand-induced equipment failures. This article analyzes the deployment of an autonomous, subsurface hydro-thermal excavation system within the Suez Canal. Driven by a standardized, compact subcritical nuclear core, this system replaces mechanical cutterheads with supersonic phase-change steam jets and replaces structural concrete liners with in-situ soil vitrification shoes. By operating completely underwater, the machinery bypasses atmospheric dust risks and utilizes the canal's vast water table as an infinite heat sink. The excavated material is liquefied instantly and transported via a zero-moving-part, cascaded jet-pump pipeline network directly to the Mediterranean and Red Seas, establishing a highly efficient paradigm for global infrastructure development.

1. The Suez Canal Operational Environment: The Sand Trapping Phenomenon

Expanding or deepening a high-traffic maritime corridor like the Suez Canal presents severe environmental challenges for traditional surface machinery. The local geography consists primarily of loose quartz sand, dense clay, silt, and gypsum strata, layered under a hyper-arid climate.

The Surface Equipment Failure Mode

Conventional diesel-powered dredgers, excavators, and heavy transport vehicles operating on the surface face rapid mechanical degradation due to micro-fine silica dust.

Internal Combustion Failures: Even with heavy filtration, micro-fine sand particles breach air intakes and mix with lubricants, forming an abrasive grinding paste that destroys engine cylinders and valves within days.

Thermal Runaway: High ambient desert temperatures frequently exceed 45°C. Radiator cooling fins quickly become packed with airborne dust and sand, insulating the cooling cores and causing catastrophic engine overheating.

Cutterhead Wear: In-water mechanical excavation relies on rotating steel teeth or cutter discs. The high quartz content of the canal sand causes extreme abrasive wear, requiring frequent operational shutdowns to replace dull or fractured components.

The Subsurface Hydrostatic Advantage

By moving the entire excavation process completely underwater to the canal floor—at depths between 25 and 30 meters—the system inverts these reliability metrics.

The system is completely isolated from the atmosphere, eliminating dust ingress and air-filtration dependencies.

At 25 meters depth, the surrounding water table acts as an infinite, high-efficiency thermal sink. The outer metallic skin of the robotic chassis rejects waste heat directly into the water-saturated geology, maintaining stable core cooling regardless of surface weather conditions.

2. Direct Hydro-Thermal Excavation and In-Situ Bank Vitrification

The machine executes expansion through a continuous, two-stage spatial cycle that combines forward-facing hydro-thermal cutting with trailing radial consolidation.

Mode 1: Supersonic Vapor Spallation

The primary borer robot advances along the canal shelf without any moving mechanical cutting bits. Pressurized seawater, heated to 200°C by the internal primary liquid lead loop, is delivered to forward convergent-divergent nozzles.

Because the ambient hydrostatic pressure at the canal bottom is approximately 0.25 MPa, the 200°C water instantly flashes into supersonic steam upon exiting the nozzles. This high-velocity vapor jet destroys the soil matrix through a combination of kinetic erosion and intense thermal shock fracturing. The loosened sand and clay grains are immediately suspended in the turbulent steam-water stream and forced backward along the machine chassis.

Mode 2: In-Situ Radial Sintering

To prevent the newly cut canal banks from slumping back into the channel, the trailing shield of the machine stabilizes the geology without utilizing external concrete segments, steel sheet piles, or permanent pipes.

Articulated metallic expansion shoes are driven outward radially by an internal closed gas loop operating at 10 MPa and 600°C - 700°C. This intense pressure physically crushes the loose mud and sand into a highly dense matrix. Simultaneously, the extreme heat transfers directly into the compressed layer. The marine salt flakes (NaCl and CaSO₄) deposited on the walls during the steam-boring phase act as a chemical flux, breaking the silicon-oxygen bonds in the native quartz sand. This lowers the melting temperature of the soil, causing it to soften and vitrify into a continuous, rock-hard, and completely impermeable glass-ceramic retaining wall.

3. Macro-Logistics: Subsea Slurry Pipeline Networks

Hauling millions of cubic meters of excavated sand via surface barges or mechanical conveyors creates severe shipping bottlenecks in an active international transit lane. The subsurface nuclear borer solves this by converting the excavated material into a high-velocity, underwater slurry pipeline driven entirely by the reactor's thermal energy.

The 193.3-km canal project is split into two distinct logistical sectors, exploiting the natural sea-level geography without requiring locks:

The Northern Sector: For machines operating from Port Said down to the Great Bitter Lake, the high-temperature steam breaks down the cohesion of dense canal clays into a low-viscosity fluid. Heavy-duty jet pumps located behind the borer head utilize the fluid momentum to vacuum this slurry, driving it northward through a bed-laid composite pipeline that discharges directly into the deep currents of the Mediterranean Sea.

The Southern Sector: For machines operating from the Great Bitter Lake down to Suez Port, the cascaded line of support robots maintains high pumping pressures, driving the liquefied sand slurry southward to discharge into the Gulf of Suez (Red Sea).

Because the pipeline rests completely on the subsea shelf outside the central navigation prism, mega-container ships can pass safely overhead without halting the expansion project.

4. Alternative Global Use Cases

The unified core architecture and hydro-thermal excavation methodology can be applied to several other critical global infrastructure projects where traditional civil engineering is restricted by geology, depth, or environment.

The Kra Canal (Isthmus of Kra, Thailand)

Proposed to bypass the congested Strait of Malacca, a shipping canal through the Isthmus of Kra requires cutting through highly variable tropical terrain, including hard granitic rock formations and thick marine clay layers. Traditional dredging and surface blasting face massive economic and environmental barriers. The subcritical nuclear borer can operate directly from the Gulf of Thailand, driving subterranean channels through the granite spine via thermal spallation while simultaneously baking the highly unstable marine clays into stable, glass-ceramic retaining walls.

Inland Arid Water Convection Networks

To combat desertification and secure agricultural water supplies, deep water-convection tunnels can be driven from coastal desalination nodes directly into arid continental interiors (such as the Australian Outback or North African basins).

As the machine advances inland, the geology transitions from wet marine silt to dry freshwater tables at depths of around 20 meters. Without marine salt to act as a natural chemical flux, the closed gas loop (Ar-He or sCO₂) is driven higher—up to 750°C—to successfully sinter pure inland quartz sand and silicate clays into a structural pipeline, enabling long-distance, gravity-fed freshwater transport without requiring imported piping infrastructure.

5. Conclusion

The integration of a standardized, compact subcritical nuclear core into subsurface marine robotics completely redefines the boundaries of mega-scale excavation. By eliminating air-breathing combustion engines, moving mechanical cutterheads, and consumable concrete liners, the system achieves unprecedented operational reliability. Whether expanding vital international shipping lanes like the Suez Canal or driving critical water infrastructure through arid continents, this hydro-thermal architecture leverages the surrounding environment as both its tool and its protector, delivering high-efficiency civil engineering with zero atmospheric dependence.

Underwater Nuclear Robotics

Traditional nuclear technologies are developed as isolated, independent projects—ranging from massive, rigid land-based installations to highly specialized, single-use military variants. Because of this fragmented development path, projects take decades to realize and suffer from high failure rates. This paper proposes a unified design approach: by aggregating the requirements of both land-based and mobile applications from the outset, we can develop a compact, lightweight, and standardized subcritical core. While a lighter, compact core requires a higher initial investment, it unlocks mass production, modular factory assembly, and rapid field deployment for land grids, allowing plants to start generating revenue years ahead of schedule. Crucially, this identical core can then be adapted directly into high-power mobile sea robotics with minimal modification. By operating in a water-rich environment, these robots exploit an infinite natural heat sink to manage the core safely, utilizing direct-loop thermodynamics to replace mechanical wear parts with high-energy steam jets and thermal compaction shoes.

1. The Unified Core Philosophy: Aggregated Requirements

The core problem with modern nuclear engineering is not the technology itself, but the economic framework. Because every reactor is treated as a tailor-made, site-specific civil engineering project, the industry is plagued by cost overruns. If we look at nuclear development from an aggregate requirements perspective, a clear engineering synergy emerges:

Designing a core to be lightweight and compact is a strict requirement for mobile robotics, but it is traditionally ignored for land-based plants where space is abundant. However, a compact, lightweight core directly benefits land installations by enabling Modular Fast-Deployable Reactors.

Instead of pouring concrete on-site for a decade, these standardized cores can be mass-produced in a centralized facility and shipped via standard transit. The slightly higher material cost of a compact design is rapidly paid off by drastically reducing the time it takes for a power plant to go from ground-breaking to active operation. Once this universal core is established, it can be dropped into a marine robotic chassis with zero fundamental changes to the nuclear architecture.

2. Core Propulsion and Power: The Subcritical HTS Architecture

To achieve the necessary weight and size reduction for dual-use applications, the system abandons traditional critical-reactor baselines. Instead, it pairs a compact particle accelerator with a subcritical, non-enrichment fuel matrix.

The Accelerator Driver

The system uses a 2 meter diameter circular particle accelerator (an isochronous cyclotron) to accelerate protons to energies between 100 - 150 MeV. To bend the proton beam within this small radius, the cyclotron uses high-temperature superconducting (REBCO) magnets cooled by liquid nitrogen to 77 K. The magnetic field is kept between 1.5 - 1.8 T, which sits safely below the 2.14 T saturation limit of standard pure iron cores. This lower magnetic field reduces the mechanical bursting forces on the magnet coils, allowing for a lighter, more durable internal support structure.

The Subcritical Core Mechanics

The proton beam exits the cyclotron and enters the core, striking a composite matrix where solid Uranium-238 is completely submerged in a bath of liquid molten lead. Because U-238 is fertile rather than fissile, it cannot sustain a nuclear chain reaction on its own. The system is completely subcritical, operating with an effective multiplication factor between 0.53 and 0.77. The molten lead serves a dual purpose: it acts as a high-efficiency liquid heat conductor that fills all structural gaps around the uranium blocks, and it acts as a primary coolant. Because lead has a very low neutron absorption rate, it allows the fast neutrons generated during fission to pass through unhindered. When the 150 MeV protons hit the Uranium nuclei, they induce fast fission, splitting the uranium atoms and releasing 4 to 5 fast neutrons along with roughly 200 MeV of thermal energy per event. This interaction multiplies the input beam power by a factor of 10 to 20. The inclusion of liquid lead fundamentally hardens the safety profile. If any malfunction occurs, turning off the accelerator beam stops the fission process instantly within milliseconds. If the machine loses all active pumping power, the liquid lead acts as a passive safety system: it absorbs the immediate decay heat and eventually cools into a solid metal block, hermetically sealing the uranium fuel inside a stable, solid matrix.

3. Hydro-Thermal Cooling and Propulsion Dynamics

By submerging the Uranium-238 in a bath of molten liquid lead, the reactor core gains an immense thermal buffer. Molten lead has an exceptionally high heat capacity and stays liquid across a vast temperature range (327°C to 1749°C). This liquid metal envelope acts as a massive shock absorber for heat fluctuations, absorbing sudden spikes in energy and smoothly distributing the thermal load to the secondary cooling systems.

Because the machine operates 100% underwater within the canal prism, direct-intake seawater is used as the primary external cooling medium. To prevent the classic failure mode of catastrophic salt scaling on the internal heat exchangers, the system utilizes controlled crystallization and dynamic shedding techniques. By keeping the seawater loop boundary layer within a strict temperature window (180°C to 200°C), marine salts like calcium sulfate form a brittle, weakly adhered crust on low-surface-energy coatings. Periodic, multi-second cuts to the cyclotron beam cause rapid thermal contraction of the heat-exchanger walls, shattering this brittle salt layer and automatically flushing it out of the core as hard flakes.

4. Direct Hydro-Thermal Excavation and In-Situ Wall Compaction

This section details how the robot interacts with the geology to dig the tunnel and form its own structural shell simultaneously, completely eliminating the need for brought-in cement, steel casings, or permanent pipes.

Mode 1: Steam-Only Boring (Excavation)

The Borer Robot functions without a mechanical cutterhead. Pressurized, 200°C seawater from the reactor loop is channeled directly to forward-facing, convergent-divergent nozzles at the front of the machine. The moment this fluid vents into the lower ambient water pressure of the tunnel face, it instantly flashes into supersonic steam.

This high-velocity steam jet cuts into the native canal sand, silt, or clay through intense kinetic erosion and thermal stress fracturing. Because the soil is blown apart by fluid dynamics alone, there are no high-torque bearings or metal teeth to wear out or seize up from abrasive sand grains. The broken soil particles are naturally forced backward along the sides of the machine body into collection channels.

Mode 2: In-Situ Radial Sintering (Wall Compaction)

To stabilize the tunnel walls without installing concrete segments or permanent piping, the machine utilizes a closed, high-temperature gas loop (Argon-Helium or sCO₂) heated to 600°C - 700°C at an internal pressure of 10 MPa. This gas is routed to articulated metallic expansion shoes running around the outer circumference of the trailing shield.

1. Mechanical Crushing: Because the internal gas pressure (10 MPa) is far higher than the external water table pressure, the metallic shoes strike outward radially, physically crushing the loose mud, native sand, and displaced salt flakes into a highly compacted, dense soil matrix.

2. Vitrification (No Cement Needed): As the shoes hold this compacted layer under immense pressure, the 600°C heat transfers directly into the soil. The marine salt flakes (NaCl and CaSO₄) deposited during the excavation phase act as a chemical flux, lowering the melting point of the native silica and clays. The soil matrix softens, cross-links, and vitrifies into a continuous, rock-hard, and completely impermeable glass-ceramic tunnel lining. The tunnel becomes its own structural pipeline.

5. Robotic Functional Varieties and Operational Division of Labor

Instead of forcing a single machine to handle all engineering tasks, the system splits operations between two specialized robotic varieties: the Borer Robot and the Support Robot. This division of labor maximizes mechanical reliability and prevents environmental thermal choking.

The Primary Borer Robot (Direct Thermal Drive)

The Borer Robot does the heavy mechanical work of destroying rock and clearing debris. While it generates a minor amount of electricity from its reactor to run its onboard sensors, steering actuators, and control computers, it does not use electricity for excavation.

Converting the reactor's megawatts of thermal energy into electricity to run heavy electric motors would introduce massive energy conversion losses and vulnerable moving mechanical parts. Instead, the Borer Robot uses a direct thermal-expansion cycle:

The primary molten lead heat is transferred directly to the intake water, driving it up to 3 MPa.
This water is routed to forward convergent-divergent nozzles, where it flashes into supersonic steam.
The high-velocity steam jet shatters the soil, while an internal jet pump utilizes the remaining fluid momentum to vacuum the debris and pump it backward.

Because the cutting tool is a fluid phase-change jet, the machine contains virtually no high-wear moving parts, completely eliminating seized bearings and worn-out mechanical cutter discs.

The Secondary Support Robot (Electric Propulsion & Logistics)

Operating a high-power steam borer inside a confined tunnel rapidly heats up the surrounding water. To maintain cooling efficiency, the specialized Support Robot operates behind the borer to handle fluid logistics, debris removal, and mechanical support.

Fluid and Debris Management: The Support Robot positions itself in the cooler, open waters of the canal channel. It pumps pristine, cold seawater through high-pressure hose lines directly to the inlet of the forward Borer Robot. Simultaneously, it acts as a heavy-duty pumping station, sucking the excavated sand-and-steam debris out of the tunnel and sending it through the discharge pipeline toward the sea. For long-distance tunnels, multiple Support Robots are deployed in a cascaded line to maintain pressure across the pipelines.

Maintenance and Pipe Laying: The Support Robot is equipped with robotic actuator arms and extensions. These arms are used to systematically lay and connect the advancing cold-water and debris lines as the borer moves forward. Additionally, these extensions allow the Support Robot to perform basic, automated maintenance and clear blockages on the trailing section of the Borer Robot without requiring human intervention.

6. Conclusion

By unifying the design requirements of modular land reactors and mobile heavy machinery from day one, we solve both the economic bottleneck of nuclear power and the mechanical bottleneck of heavy robotics. The resulting compact, subcritical core provides a standard, high-reliability engine. Dropped into a marine robotic chassis, it uses direct fluid dynamics to eliminate physical tool wear, atmospheric filters, and structural consumables, allowing for continuous, independent operation in the world's most hostile environments.

Underwater Military Base

After proposing a space military base, I thought of an underwater military base. It would be mobile like the space counterpart. Water is a good cover and shield for a mobile base.

A typical military base would be composed buildings and underground structures distributed over a large area. With a mobile underwater base, the buildings would be substituted with spherical structures to withstand pressure. They would be towed by nuclear tug submarines. The spheres would contain the ammunition, missiles and fuel. The personal would be accommodated inside nuclear submarines.

Depending on the mission, the base would be towed to an appropriate location in advance. All elements of the convoy would be covered by radar and sonar absorbing material to minimize detection. Distributing the resources among smaller units would reduce loses in case of detection.

Once in location and depending on the need, only necessary units would surface above water.

Unlike a base on land, a mobile base would only be able to service VTOL planes. However, its mobility underwater makes it a harder target for the enemy.

Underwater Pipe Organ

While listening to Xaver Varnus playing Bach’s Toccata & Fugue in The Berliner Dom, I dreamed of an underwater pipe organ fed by the gas from an underwater chimney. I got my inspiration from Captain Nemo’s organ inside the Nautilus.

Pipe organ would be played by an underwater robot. How would it sound or would it sound at all I don’t know. The whales and the dolphins would most likely hear it. Imagine them gathering around the pipe organ like inside a giant cathedral.

Here is the Music played on surface 😊

Xaver Varnus plays Toccata and Fugue in D minor (edited by Mendelssohn) on the great Sauer Organ of the Berliner Dom.

Details of International Underwater Station

A submarine hull has two major components, the superstructure and the pressure hull. The superstructure of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that resists sea pressure and maintains the submarine’s structural integrity at operating depth. I propose a double pressure hull design for the International Underwater Station (IUS) while it doesn't need to travel at high speeds. In order to increase the usable space and maintain buoyance, the hulls of the submarine will be made of concrete filled steel structures. Manufacturing big steel structures is a mature technology for ship building. This will allow low-cost building of a big submarine that can operate at considerably high depths. Concrete has a high compressive strength and can be easily used to fill the void between the steel double hull. A special composition of concrete should be used for this purpose. The concrete would also seal the leaks that may occur on the superstructure. With special composition, they would resist the corrosive sea water better than most metals. The additional weight of the concrete would also allow more hollow space inside. Heavy weight and larger dimensions would also increase the stability of the underwater research station.

IUS would have hatches to allow additional submarines to be attached to each other like in ISS. Each IUS section would have emergency rescue spheres that would take the occupants to the surface in case of an emergency. Additionally, any damaged section would be released from the rest to maintain the operation of the IUS.

IUS would accommodate small submarines for humans as well as tethered robots. This would allow detailed inspection of tight spaces. Samples gathered by these inspections would be analyzed at the onboard laboratories.

We All Live in a Yellow Submarine

International Space Station has reached its end of life and new space stations are planned. I would like to propose an International Underwater Station which would benefit humanity more than its space counterpart. An underwater habitat was described in Jules Verne's "Vingt Mille Lieues sous Les Mers" almost two centuries ago. However, we are still leagues behind creating such habitat even though we have the technology. We should start by creating an underwater research station. It would be made of specially designed submarines. These submarines would be cascaded like the space stations sections are attached to one another. As time goes by more sections would be added and the old ones would be removed.

International Underwater Station would make research on deep-sea habitat and would also clean the surrounding region as it explores. It would create underwater farms to feed its occupants like in Jules Verne's novel. With a nuclear reactor on board, it would be a self-sufficient habitat.

An autonomous ship above water would accommodate the submarine to assist in logistics and as a rescue boat in case of emergency. A smaller version of this underwater station would be deployed on Mediterranean Sea first, then a larger version on the oceans.

Underwater Construction Platform

Offshore underwater construction is a complicated and slow process. I thought about ways to speed up the construction and allow more automation. The solution was to build a cartesian building platform like in CNC machines and 3D printers. In order to accomplish flexible build volume, I thought about using scissor like extensions.  These extensions will be carried by autonomous boats with twin pontoons.  Each boat will carry two extensions; vertical extension to be lowered down to the sea floor, horizontal extension to connect with another extender boat. When four boats reach the construction site, they will extend their extensions to form a cartesian build platform. The pontoons will be filled with sea water to sink the boats slightly to improve stability. Then, other autonomous boats will arrive and attach carriages on the scissor like extensions. The extensions will have rails to stabilize the carriages. Above surface carriages will be used like cranes to lower parts underwater. After that, underwater horizontal extensions will be lowered and mounted. Then, underwater carriages will be mounted on the extensions which then carry the construction arms.

Once the cartesian construction platform is assembled by the robot boats, the underwater construction would begin. The extender boats would double as docking ports for the boats carrying construction material. They will also have vertical wind turbines to generate electricity on site to power the construction arms underwater. Human operators can also be nearby accommodated in another boat.

This method of construction would be much faster than using construction ROVs which cannot carry big and heavy parts. They are also slow and their tether pose big problems. Underwater construction platform would allow high power and data connectivity to the multiple construction arms to speed up construction and precision.

Glass Sphere of the Underwater Habitat

I chose the underwater habitat to be made of a giant laminated gorilla glass sphere with aluminum enhancements. Laminated Gorilla Glass is transparent and very strong. Properly selected aluminum alloy on the other hand is resistant to underwater corrosion and it bonds perfectly with silicon dioxide (glass).

The sphere will be constructed underwater. The glass sections will be manufactured on land and they will be connected with each other using molten aluminum underwater. It’s like an underwater stained-glass manufacturing. Instead of lead, aluminum is used to increase strength and improve water sealing.

I decided on my idea after reading these articles:

Aluminum has strong adherence to silicon and silicon dioxide

Induction Heating in Underwater Wet Welding

Induction heating aluminum underwater is technically possible. The electric required for this process would be supplied by the construction ship on the surface. The heated aluminum will then be poured on the gaps between the glasses to form a strong structure with good sealing. This technic once perfected would allow giant structures to be constructed underwater.

Building structures using smaller and relatively light weight materials (compared to steel) would allow autonomous robots to carry the construction work on site. They would be powered by electricity generated by floating vertical wind turbines attached to the autonomous construction ship.

Underwater Habitat

Building human habitat on extreme environments is a challenge. I would like to propose one for underwater.

The main habitation area will be a giant sphere made of laminated gorilla glass and aluminum. This underwater sphere will be connected to the surface by an Eiffel-like structure. The underwater Eiffel tower will form the foundation for the docking facility on the surface and the vertical wind turbine. There will be a satellite transceiver on top of the wind turbine for internet connectivity, a radar to detect the incoming ships and a light house to inform the incoming ships at night. The transportation from the surface to the ground sphere will be conducted by twin spherical elevators. The surrounding of the underwater habitat will be illuminated by the lights attached on the tower. They will be operated periodically not to disturb the life underwater. There will be artificial corals to enrich the underwater habitat.

This underwater world will be constructed by autonomous robots. I will explain it in detail in my next article.
