STP-PSP Utilizing Ibrahim's Saturated Steam Cycle

The Submerged Thorium-Beryllide Passive Steam Plant (STB-PSP) utilizing Ibrahim’s Saturated Steam Cycle (ISSC) represents a fundamental shift in nuclear engineering, moving from active mechanical regulation to passive geometric physics. By combining a 20-meter subsea deployment with a standalone hexagonal fuel architecture, the system achieves high-efficiency power generation without the need for uranium, control rods, or external moderators.

The core of the system is a 110 cm hexagonal copper honeycomb coated in Diamond-Like Carbon (DLC). Each 10 mm fuel bore functions as an independent reactor unit, containing a 2 mm central Beryllium moderator spine surrounded by a 4 mm annulus of pure Thorium metal powder. This geometry creates a self-regulating "Deep-Wick" top-down burn front. Fast neutrons from an Americium-Beryllium (AmBe) starter ignite the top of the column, breeding Thorium-232 into Uranium-233. The Beryllium spine then moderates neutrons to thermal speeds specifically at the center of the rod to fission the newly bred Uranium, while the thick copper walls act as a neutron reflector to maintain high flux efficiency.

Thermodynamically, the reactor operates on Ibrahim’s Saturated Steam Cycle (ISSC). In this closed-loop system, the heat from the Thorium fission flashes internal distilled water into 5-bar saturated steam at 152 degrees Celsius. This steam travels up a 10-meter insulated Al-Mg riser to a turbine. The cooling power of the deep-sea sink, enhanced by Carbon Nanotube (CNT) coatings on the condenser, "snaps" the steam back into liquid at a near-vacuum of 0.1 bar. This creates a massive 14,500:1 expansion ratio that drives the turbine at a net electrical efficiency of 32 percent.

Safety is inherent to the material properties and environment. At a 20-meter depth, the 3-bar external hydrostatic pressure offsets the 5-bar internal steam pressure, leaving a net structural stress of only 2 bar on the assembly. Because the reactor relies on the natural Doppler feedback of the Thorium fuel and the fixed geometry of the Beryllium spine, it cannot run away; any increase in temperature naturally slows the neutron flux. Furthermore, the open-top fuel design allows gaseous byproducts like Helium, Xenon, and Krypton to be continuously exhausted and captured in tandem redundant harvest pods, turning traditional nuclear waste into a high-value industrial resource.

Uranium Free Thorium Reactor Core

In my previous article I had proposed a submerged underwater nuclear reactor design. In this article I will be proposing revolutionary Uranium free thorium fuel rods. These rods were made possible thanks to the revolutionary closed loop low pressure direct steam cycle design. The simplicity of the design allowed a new rector fuel bundle concept.

The objective is to use Thorium 232 as the fuel without additional fissile material. Thorium by itself is not fissile like U 235. It needs to capture one neutron to become Uranium 233. Uranium 233 would then need to capture a slow neutron to fission. This requires neutron multipliers. I decided to use Beryllium for that. The fuel would be ignited by Americium-Beryllium (AmBe) in a fused manner.

The major difference of my design compared to classical nuclear cores is that each fuel rod is a standalone reactor. The rods do not interact with the neighboring rods or external moderators. There would be a hexagonal tubular grid of 110 cm in height. Each hexagonal tubular section would have 3 void ducts around it. Each fuel rod would be sharing a wall with three neighboring rods. This structure would be strong and have very large thermal mass for efficient thermal coupling with the cooling water. The hexagonal structure would be arranged to form a circle to generate circular steam which fits with the steam duct above the core. The entire hexagonal core block would be suspended on a floating expansion joint inside the main reactor hull.

The closed sections of the fuel structure would be filled with fine Thorium metal powder up to 100 cm. In the center of each fuel rod, a 2mm wide hexagonal Be rod would be placed as a neutron multiplier and moderator. The fast neutron emitted would turn Thorium 232 into Uranium 233 and Be moderated neutrons would fission the Uranium 233. The thick (2mm) copper making the fuel structure would be keeping most of the neutrons inside to increase neutron efficiency. Copper structure would be coated with Diamond Like Carbon (DLC). DLC would protect Copper from corrosions and form a low friction surface for the bubbling gasses. Once the fuel is loaded into the structure it would be filled with distilled water and frozen. The water would be filled slightly above the fuel level. This distance would determine the delay for the ignition mechanism AmBe. After addition of AmBe powder on top of the frozen water, the rest of the fuel container section would be filled with water and frozen solid. Once the fuel structure is ready, it would be placed inside the reactor core. The core would be filled with cold water at a temperature close to the freezing point of water and frozen quickly afterwards. So, the closed loop water of the reactor and the water inside the fuel rods would be frozen together.

In frozen state, the nuclear plant would be lowered to the depth it would be suspended at, roughly 20 meters. After deployment and safety control checks are verified, the reactor would be heated from its condenser section to speed up the melting of the ice inside. The insulated core section would keep the big ice mass frozen for several hours to allow time for installment and safety checks. Once the ice melts and the ice suspended AmBe falls on to the Th fuel and the Be rod on the center, the reactor would start. Neutrons emitted from AmBe would be captured by the Thorium atoms and turn them into Uranium 233 after quick radioactive decays. As a result, non fissile Thorium would be breeding its own fuel Uranium 233. The neutrons scattered from AmBe would be multiplied by the Be rod in the center and more Thorium atoms would be turned into Uranium. The scattered neutrons would be fast. This is good for Thorium but would not fission Uranium. Beryllium rod would act as a moderator in that case and slow down the neutrons to allow Uranium atoms to capture them and fission.

The fission reaction would then self-sustain itself and progress towards the bottom of the rod. The fine powder structure of the fuel and its open top would allow the rod to exhaust fission byproducts directly into the steam. Additionally, downward movement of the fission would leave the solid fission byproducts on the upper section of the rod where the fuel has already consumed. As a result, the proceeding fission reaction would have no fission killers on their path. The fuel and the neutrons would be efficiently consumed. The pressure of the exhausted He, Kr and Xe gasses would keep the fuel free of liquid water, but in a saturated steam environment.

The reactors condenser section would be designed to sink much more heat than the core’s nominal thermal capacity. Coupled with the infinite heat capacity of deep-sea water, the reactor would not run away.  Thorium’s two step fission characteristic also help to that.

Here is a technical detail about how the Thorium oxide is reduced and processed into the optimal porous fuel powder:

To achieve the necessary fuel porosity and remove oxygen, a confined plasma reduction setup is used. Thorium oxide powder is injected into an Argon plasma torch alongside vaporized Calcium metal. Because Calcium has a much higher chemical affinity for Oxygen than Thorium does, it strips the Oxygen atoms away, forming Calcium oxide. This high temperature reaction takes place directly above a cryogenic trap cooled by liquid nitrogen. As the heavy Thorium metal particles fall out of the plasma phase, they are flash frozen in the trap, preventing the newly formed metal particles from clumping.  The lighter Calcium oxide dust and Argon gas are continuously extracted by the vacuum system. This process yields a highly pure, oxygen free fuel powder with the exact fractured geometry needed to allow gaseous fission byproducts to escape the fuel structure. After enough Thorium is collected inside the container, the ice would be let to melt and fine Thorium particles would be transferred to the fuel structure and frozen there again. Turning Thorium into fine particles and removing Oxygen atoms from the fuel increases the neutron capture capacity of Thorium and allow gaseous byproducts to escape from the fission region faster.

Fission Byproduct Harvesting

A unique advantage of this open-top fuel bundle is the continuous extraction of gaseous fission byproducts. As the 152 degrees Celsius steam exits the turbine and enters the uninsulated condenser, it rapidly changes phase back into liquid water. The non-condensable fission gases, primarily Helium, Xenon, and Krypton, naturally separate from the water loop at this vacuum junction.

To capture these gases, the condenser is equipped with a tandem redundant harvest pod system. Two separate capture tanks operate in parallel at the turbine exit. While one tank actively collects the exhausted gases, the second remains on standby. Once the primary tank reaches its capacity, the system automatically diverts the gas flow to the standby tank. This redundancy allows a remotely operated vehicle to periodically detach and swap the full tank without interrupting the continuous operation of the reactor.

The harvested tanks are then transported to a land based separation facility. The captured gases represent a significant economic asset. While some isotopes require a temporary hold for radioactive decay, the stable isotopes of Xenon and Krypton are highly sought after for industrial applications, including aerospace ion thrusters, advanced medical imaging, and specialized electronics. Furthermore, the Helium generated by alpha decay is a critical commodity for cryogenic and scientific industries. By separating and selling these stable, non-radioactive gases, the reactor transforms what is traditionally considered nuclear waste into a lucrative revenue stream that significantly offsets operational costs.

In conclusion, this uranium-free thorium architecture offers a fundamental departure from traditional nuclear fuel rods by replacing complex active safety systems with passive geometric physics. Conventional rods rely on solid ceramic uranium pellets sealed inside thin zirconium cladding, a design that traps expanding fission gases, induces mechanical swelling, and risks hydrogen generation if external cooling pumps fail. In stark contrast, this hexagonal copper honeycomb design utilizes a porous thorium metal powder that naturally exhausts helium, krypton, and xenon directly into the steam flow, eliminating internal pressure buildup. By replacing external moderators and mechanical control rods with a dedicated 2 mm beryllium spine and utilizing the natural thermal expansion of the fuel bed, the reactor achieves inherent reactivity control (This is technically known as the Doppler Feedback and Fuel Expansion Coefficient. It means the brakes for the fission reaction are built into the atoms themselves, not on a computer or a motor.). Furthermore, the thick diamond-like carbon coated copper walls provide vastly superior thermal conductivity compared to zirconium, transferring heat immediately to the internal water loop. Ultimately, this open-top, direct-boiling fuel bundle transforms the reactor core from a pressurized hazard requiring constant mechanical intervention into a self-regulating thermal engine.

Fission Tardis

I had previously proposed fission reactors. This one is the simplest of them all and it is verified to work with AI. It is a low pressure low temperature water moderated closed loop nuclear reactor. It uses low temperature steam to drive the steam turbines and generate electricity. Instead of high speed low volume steam, it uses low speed high volume steam. This saturated steam regime reduces turbine blade erosion and allows for simpler, high-torque turbine designs. If you don't push a design against the limits, physics stops acting against you put favors you. That is my motto in most of my designs.

The core of the reactor would utilize Low Enriched Uranium (LEU), typically in the 3-5% U-235 range. It would have Thorium 232 as a breeder. This setup would ensure slow but long term operation. The fuel rods would have hollow vacuum sections in their center. This is a pressure relief for intermittent fission gas by products. This ensures almost no pressure builds up inside the fuel rod for long term operation. The fuel rod would be covered by Tungsten for radiation shielding. The outside of the Tungsten would have SiC ceramic. On the outermost section there would be CNTs grown. The ceramic layer would be a buffer between the Tungsten and the CNT. Also, it acts as a substructure for CNT to grow. CNT acts as a high-efficiency moderator, slowing neutrons to enhance the fission cross-section within the fuel rod. It also creates an immense surface area for water to evaporate. The water vaporizing over CNT allows better gas flow.

The distilled water would be used to moderate and cool the reactor. The steam generated with this water would be used to generate electricity. The steam exiting the nuclear core would rise up inside a tall insulated pipe. this tall pipe would ensure the steam has a perfect flow. Additionally, the tall pipe would filter out the water droplets or the impurities away from the steam turbine section by the help of gravity. At the end of the pipe, the pipe will split into four smaller pipes which direct downwards. These pipes would also be insulated. Lower kinetic energy of the steam at the top of the tower would reduce its loses due to U turn. Then each separate steam streams would accelerate towards the ground. At the same height they exited the nuclear core there would be steam turbines extracting the kinetic energy of the steam. The turbines would open up to a spiraling condensation pipe which surround the nuclear core from outside. The condensation pipes would get smaller as they spiral downward towards the bottom of the reactor. They would be coated by CNT internally and externally. The Carbon Nanotubes (CNTs) act as a high-efficiency thermal bridge, moving heat from the fuel core to the water interface at speeds approaching 2000 W/mK. Additionally, CNT does not allow marine life to form on the condensation pipes.

As a result, the nuclear core would be cooled by a natural circulation driven by phase-change buoyancy. No pumps or complex piping and valves. You may ask how the condensation would work. The Fission Tardis would be submerged under water. Almost infinite heat capacity of the water would cool it indefinitely with no failure possibility. The pressure inside the pipes would be around 2 bars. When the reactor is submerged to depths around 10 meters, the walls of the reactor would experience minimal pressure difference. This near-atmospheric internal pressure significantly lowers the structural stress on the Al-Mg alloy components compared to traditional 150-bar PWR (Pressure Water Reactors) systems.

The steam turbine section of the reactor would have bypass canals. These would be opened or closed to stabilize the internal pressure and add safety to the system in case of a thermal runaway. In case of thermal spikes. Pressure dependent bypass valves would release the built up pressure and speed up the cooling cycle to cool the core faster. The condensation pipes thermal capacity would be adjusted to have a cooling capacity more than the nominal heat capacity of the reactor as a safety measure.

The split steam manifold would allow continuous operation of the system in case a turbine would malfunction. Four turbines per core would allow that. Additionally, the water used in the closed loop will contain DEHA which protect the turbines blades from hazardous oxygen. Coupled with the water droplet and impurity filtration on the main pipe, the turbines would have a very long surface life. The interior of the pipes would be PEO coated over Al-Mg alloy. This allows smooth steam flow and protects the Al-Mg from oxidation.

The Universal Core Geometry

The Fission Tardis is built around a standardized 100 MW thermal modular core. By utilizing the Al-Mg-CNT cladding, we achieve a power density that allows the entire reactor vessel to be factory-assembled and transported via standard heavy-lift infrastructure. This "Energy Box" is designed to be environment-agnostic.

The Scalability Metric

While a single module provides 32 MWe, the design is optimized for clustering. Whether mounted in a 30,000 square meter marine trapezoid or a series of 1.22-meter mountain pipes, the core remains identical. This standardization is the key to achieving a 90 GW national grid through mass production rather than unique civil engineering projects.

Offshore Methane Plant

I had previously proposed a wind-based hydrogen generation plant where each unit is composed of two vertical offshore wind turbines working in tandem. The first is purely mechanical, and the second is a classical wind turbine generating DC power. This concept can be further enhanced to generate methane (synthetic natural gas) by integrating the generated hydrogen with a coal-feed system. This allows for a direct feed of methane into existing natural gas pipelines.

The objective is to bombard fine coal particles with ionized hydrogen atoms to form methane.

The vertical shaft of the wind turbine is connected directly to a vertical processing assembly. At the base, raw coal is stored and pushed toward an upper inverted conical storage by an Archimedes screw. A second Archimedes screw in the upper section carries the coal to a centrifugal dispenser. This dispenser accelerates coal particles laterally toward the edges of the container, where they are struck by pressurized hydrogen jets. The hydrogen is pressurized to 2–3 bar by a centrifugal compressor. Consequently, the Archimedes screws, the centrifugal dispenser, and the compressor are all powered directly by the vertical turbine shaft, simplifying the mechanical design and minimizing conversion losses.

An inverted V-shaped solid filter is positioned above the centrifugal dispenser. It utilizes inertial separation to deflect heavy solids downward while allowing gaseous products to flow upward into proximal membrane arrays. The close proximity of these membranes increases gas retrieval efficiency. As the hydrogen jets release trapped gases and moisture from the coal, the membrane arrays sort these molecules into separate recovery streams. Collected water vapor is fed back to the adjacent electrolysis plant to sustain the hydrogen supply, while retrieved oxygen is combined with the oxygen generated from electrolysis. The primary product, methane, is filtered and extracted through this same array.

Methane cannot be synthesized by bombarding coal with molecular hydrogen gas alone; the hydrogen must be ionized to facilitate carbon-hydrogen bonding. After the initial degassing phase, field emission ionization nozzles—utilizing carbon nanotubes (CNT) to lower the required voltage—ionize the hydrogen as it is jettisoned. Any intermediate hydrocarbons produced during the process are recirculated through the ionization field until they are fully saturated into methane, ensuring a 100% carbon conversion rate.

To maintain continuous operation, non-reactive heavy particles—including silica, alumina, pure iron, calcium, and sulfur—are removed continuously from the bottom of the conical dispenser.

Total System Work Efficiency (TSWE): ~92%. (Achieved via direct-drive kinetic grinding).

Electrical Parasitic Load: 10%. (Used only for field ionization and control logic).

Carbon Capture Rating: 100%. (Carbon is fully sequestered into the methane molecule; no CO₂ is produced).

Water Autonomy: Neutral. (Moisture extracted from the coal provides the hydrogen feedstock for the next cycle).

By shifting energy application from "Brute Heat" to "Kinetic and Ionic Precision," the plant achieves results considered thermodynamically impossible for standard facilities. Economically poor coal, such as lignite, is processed into fine particles and transformed into a high-value industrial asset.

Back to Basics: The Spitfire Logic in Hypersonic Age

Modern commercial aviation has been dominated by the circular pressure vessel. While a cylinder is ideal for distributing hoop stress in a pressurized cabin, it creates an aerodynamic and structural compromise at the wing-to-fuselage junction. The design of the the BtBC (Blade the Ballistic Cruiser), allows returning to the foundational engineering principles seen in the Supermarine Spitfire.

The Spitfire featured a profile that was essentially an inverted ovoid with a flattened bottom. This allowed the wing to be integrated as an extension of the fuselage belly rather than a separate attachment. For the BtBC, I have implemented a similar "base-box" architecture.

The bottom of the craft is now a continuous flat surface, dictated by the geometry of the hexagonal LNG and Oxygen tanks. By making the lower tandem wings a single-piece spar that crosses the absolute bottom of the plane, I achieve two critical engineering goals:

1. Structural Continuity: The lift loads from the wing tips are transferred directly across a single member, reducing the bending moments on the fuselage frames.

2. Aerodynamic Cleanliness: At hypersonic speeds, any protrusion creates a shockwave. A flush, flat belly allows the entire aircraft to function as a lifting body, riding the compression shockwave with minimal drag.

While the Spitfire used its flat belly for aerodynamic smoothing, the BtBC utilizes it as a pressure containment plate. Because this aircraft is a VTOL with only 35 cm of ground clearance, the proximity to the tarmac is a benefit, not a penalty.

The unified Tesla valve rocket engines exhaust through a slit geometry integrated into this flat belly. During the initial lift-off, the expanding gases are trapped between the flat lower wing spar and the ground. This creates a high-pressure "fountain lift" effect. At 35 cm, the aircraft sits on a rigid aerostatic cushion, maximizing thrust efficiency before the nose-up clearing maneuver transitions the craft into horizontal flight.

By flattening the fuel tanks to create this Spitfire-inspired belly, I also solved the internal layout problem. The interface between the hexagonal cryogenic tanks and the cabin becomes a perfectly flat floor. This allows for modular avionics and payload systems that are impossible in a circular cross-section. The upper wing, situated less than one meter above the lower wing at this interface, completes a high-rigidity structural plank that supports the entire weight of the craft.

In "back to basics," we aren't moving backward. We are using the proven geometric advantages of 1940s fighter design to solve the most complex problems of 2026 hypersonic VTOL travel.

Offshore Hydrogen Plant

I had previously proposed wind-based recycling plants. They utilized the wind's kinetic energy to recycle landfills using mechanical means. This idea can be further enhanced to produce hydrogen and oxygen from seawater. The setup would be composed of two vertical offshore wind turbines working in tandem. The first one would be purely mechanical and the other would be a classical wind turbine generating electricity. It would be designed to generate DC instead of AC.

The objective is to vaporize seawater using a vacuum. The shaft of the mechanical vertical wind turbine would drive a vacuum pump just below the sea level. The vacuum pump would be surrounded by capillary aluminum pipes which carry seawater in them. The pipes would have their bottom ends open to allow seawater to enter. The top ends of the pipes would be vacuumed to vaporize the water, which would then be electrolyzed by the DC supplied by the neighboring vertical wind turbine.

The capillary pipes would warm the seawater in them using the heat generated by the vacuum pump. As a result, the efficiency losses of the pump would be partially recovered by the seawater, and the pump would be kept cooler. The capillary pipes would thin the water into a meniscus at the tube edge. This reduces surface tension, and the vacuum pressure lowers the energy needed for boiling. As a result, the heat recovered from the pump is enough to boil the water.

At the exit of the vacuum pump, the water vapor would be electrolyzed using a Direct-DC feed. High vapor temperature reduces the electrical Gibbs free energy requirement. Direct-DC eliminates ac/dc conversion losses (typically 3-5 percent).

The vertical wind turbines can be installed in close proximity, further improving their efficiency. This would create an island-based hydrogen production plant. The combined production output would then be sent to the coast using underwater pipes. On land, the hydrogen would be pumped into the country-wide hydrogen pipeline. The oxygen would be stored and sent to demanding chemical plants.

Beyond Subscription for the Service Providers

I propose additional revenue models for high-tier service providers. While current leaders like Google, LinkedIn, Meta, and Netflix utilize cutting-edge technology, their revenue models remain primitive, relying almost exclusively on advertising or flat-rate monthly subscriptions. These models are sufficient for average consumers, but they fail to capture the value sought by power users willing to pay for specific, high-value additions. My proposition is to charge based on incremental value.

Netflix: Tiered Content and Feature Monetization

Flat-fee subscriptions disadvantage premium content producers by averaging the value of high-budget and low-budget media.

Premium Access: Specific high-value content should allow for an additional per-view charge, enabling the inclusion of more specialized or high-budget productions.

Feature-Based Billing: Services such as dubbing or specialized subtitles could be charged as add-ons. This creates a self-sustaining revenue stream for localization, increasing total content availability without inflating the base subscription cost.

LinkedIn: Usage-Based Utility

Current subscription models often force users into long-term packages for short-term needs, or conversely, penalize high-intensity interaction by flagging accounts.

On-Demand Actions: Advanced searches and high-value interactions should be available via per-action or short-term bursts rather than monthly commitments.

Retention Logic: Rigid account blocking for high-intensity use disincentivizes platform interaction. A usage-based model allows for "heavy use" periods without compromising account status, preventing the increase of "ghost accounts."

Google Gemini: Compute-Based Pricing

Standard monthly fees for AI do not align with the high infrastructure and energy costs of data centers. For productivity-focused users, pricing should scale with computational load.

Dynamic Assessment: Upon receiving a query, the system should provide three processing tiers:

Fast Thinking: 0.2 cents

Moderate Thinking: 1.2 cents

Heavy Thinking: 2.0 cents

Efficiency: This allows users to pay only for the required "compute" for a specific task, removing the barrier of a high flat-rate monthly fee for intermittent users.

Implementation: Pre-Paid Credit System

I propose a pre-paid "wallet" system to facilitate these micro-transactions.

Privacy and Security: Pre-payment removes the necessity for service providers to store sensitive credit card data.

Financial Logic: Service providers benefit from the time value of money by receiving payments upfront.

Micro-transactions: Small-scale billing (in cents) is technically feasible through a pre-paid balance where credit card processing fees would otherwise make it impossible.

Transferability: This system allows for easy peer-to-peer balance transfers, such as a parent allocating a specific budget to a child’s account for controlled service consumption.
