TideAir and Distributed Neon Geologies

1. Evidence state and paper boundary

Paper-level evidence state: HYPOTHESIS.

TideAir is a specified invention architecture assembled from real industrial and marine-energy mechanisms. Large cryogenic air-separation units exist. Rare-gas recovery from ASU side streams exists. Tidal, current, wave, hydroelectric, and nuclear power exist. Hydraulic power take-off, accumulators, industrial compressors, molecular-sieve pretreatment, cryogenic columns, and high-purity gas finishing all exist.

What does not yet exist is a TideAir installation demonstrating that these elements can be integrated at a useful cost, environmental burden, uptime, and rare-gas yield. No site has been selected. No marine-energy resource assessment, geotechnical survey, front-end engineering design, process simulation, environmental review, or product qualification has been completed. The three publication plates in this paper are corrected conceptual diagrams, not construction documents.

The paper therefore separates four levels of statement:

1. Source-reviewed facts about atmospheric neon, air separation, marine energy, and existing gas infrastructure.
2. First-order physical bounds that can be checked from concentration, flow, head, area, and time.
3. Specified architecture describing how a coherent TideAir system would be arranged.
4. Hypotheses about cost, recoverability, deployment, strategic value, and peace effects that require evidence.

The phrase peace technology is used here in a narrow infrastructure sense. Redundant production cannot end war. It can reduce the strategic leverage created when civilization-critical materials depend on a few exposed facilities.

2. Abstract

Neon is present everywhere in the atmosphere but only at approximately eighteen parts per million by volume. Industrial production therefore depends on processing immense quantities of air, enriching a crude neon-bearing stream inside a large air-separation unit, and purifying that stream in specialized equipment. The result is a peculiar strategic material: geologically ubiquitous, industrially scarce, and vulnerable to the geography of whatever steelworks, oxygen plants, purification companies, and logistics networks happened to inherit the production chain.

This paper proposes TideAir, a modular coastal rare-gas platform in which a site-scale marine-energy system supplies predictable power to conventional cryogenic air separation and rare-gas purification. The invention is not a seawater-to-neon process and does not assume that a few tidal pistons can power a major ASU. Its corrected architecture isolates seawater from process air, converts tides or currents into an electrical or hydraulic power bus, buffers that energy, and feeds a centralized gas refinery supplied by parallel modular intake and pretreatment trains. Oxygen, nitrogen, and argon remain the economic base products; neon is treated as a strategic co-product and reserve material.

A 150,000 cubic-meter-per-hour air stream contains a theoretical maximum of approximately 2.73 cubic meters per hour of pure-neon equivalent on the same volumetric basis. That number is a concentration ceiling, not a production forecast. Finished output is the ceiling multiplied by plant availability and total recovery across enrichment, transport, purification, and storage. The paper also corrects the scale of the tidal mechanism: a ten-meter-diameter shaft working across a ten-meter tide averages only about 1.8 kilowatts over a half-cycle before losses, while a one-square-kilometer impounded area across the same range approaches 22.5 megawatts before losses. TideAir is therefore a site-scale tidal-current, barrage, lagoon, or large marine-energy campus coupled to an industrial gas plant—not a row of small shafts acting as a free compressor.

The broader program is called Distributed Neon Geologies. Different regions may use different natural advantages: tides, hydroelectricity, nuclear baseload, curtailed renewables, existing oxygen demand, rare-gas secondary streams, helium-processing infrastructure, or cold-region storage. Russia is examined as a bounded case study because it combines helium-bearing gas processing, Arctic and Pacific tidal resources, and large industrial geography. The paper explicitly rejects the inference that helium-bearing geology constitutes a bulk-neon deposit. Natural-gas noble-gas anomalies are an assay target, not a production claim.

The central proposition is that neon security should become a deliberate regional capability rather than an accidental byproduct of a narrow historical supply chain.

3. Why neon becomes a geopolitical material

Neon is chemically inert and physically ordinary enough to be present in every breath, yet its industrial supply behaves like that of a scarce mineral. The contradiction begins with dilution. Linde describes atmospheric neon at roughly 18 ppm and states that rare-gas recovery requires air-separation units with intake capacity of at least 150,000 cubic meters per hour. In its described process, one ASU stage can enrich the neon-bearing fraction to approximately fifty percent before a dedicated purification plant finishes the separation. Linde also emphasizes that the volume recovered at each ASU is small enough that an economically useful supply depends on a dense production network. [P30-S02]

The semiconductor connection raises the consequence of that network shape. Neon is a major buffer component in excimer-laser gas mixtures used to generate deep-ultraviolet light for lithography. [P30-S04] In 2022, Reuters calculated that two Ukrainian companies supplied roughly 45 to 54 percent of the world's semiconductor-grade neon before their operations stopped during Russia's invasion. [P30-S15] The figure was a moment-specific market estimate rather than an eternal share, but it exposed the structural weakness: the atmosphere was global while purification capacity was concentrated.

The production chain was not concentrated because Ukraine possessed unique neon-bearing rock. It was concentrated because large upstream industrial-gas streams, purification expertise, qualified customers, logistics, and historical investment aligned there. The proper response is not to search for a replacement monopoly. It is to make the capability more distributed.

4. The concentration ceiling

The first useful calculation is independent of plant design.

neon-equivalent flow = air flow × atmospheric neon fraction

Q_Ne,max = 150,000 m³/h × 18.18 × 10^-6
         = 2.727 m³/h

The two volume terms must use the same temperature and pressure basis. At continuous operation, the corresponding annual volume ceiling is:

2.727 m³/h × 8,760 h/y = 23,888.5 m³/y

This is not the annual product output. A defensible planning equation is:

Q_Ne,product = Q_air × x_Ne × availability × total recovery

where total recovery includes capture in the ASU, transfer of the crude neon-helium fraction, purification yield, handling losses, off-spec product, and storage losses. Until a process vendor or simulation establishes those factors, the paper publishes no recovered-output promise.

Four parallel 150,000 m³/h intake equivalents would process 600,000 m³/h and contain 10.91 m³/h of theoretical pure-neon equivalent. That is enough to motivate a strategic plant; it is not enough to validate one.

5. What the original visual studies discovered

The first TideAir plates were valuable because they made the complete machine visible. They joined three ideas that are usually considered separately:

• a modular, deliverable air-intake architecture;
• a slow, predictable marine-energy mechanism with mechanical storage;
• a conventional gas-refinery backend that accumulates a rare output over time.

They also made several assumptions too quickly. One plate labeled the system as one-hundred-percent tidal without sizing the tidal resource. Another assigned a neon production rate without deriving recovery. The compressor discharge was illustrated as though one pressure applied to every ASU architecture. Small buoyancy shafts were drawn at a scale that visually implied they could support the full plant.

Those are normal errors in an invention sketch. A concept plate asks whether the parts form a meaningful whole. A publication plate must also show where the whole is physically bounded. The corrected TideAir architecture preserves the invention and removes the accidental claims.

6. TideAir v1: corrected system architecture

TideAir v1 is best understood as two coupled plants sharing one site.

6.1 Plant A: marine-energy and buffering system

The marine side converts a local resource into a controlled power bus. Depending on the site, it may use:

• tidal-stream turbines in high-velocity channels;
• a tidal lagoon or barrage with reversible turbines;
• oscillating-water-column or wave devices;
• buoyancy mechanisms driving hydraulic power take-off;
• conventional hydroelectric equipment where a basin already exists;
• a hybrid of marine power, grid power, storage, and another baseload source.

Power may reach the ASU as electricity, hydraulic shaft assist, or both. The default v1 architecture is electrical because it allows mature motors, variable-frequency drives, protection systems, metering, and grid interaction. A hydraulic subsystem remains useful where the marine device naturally produces reciprocating force and an accumulator can smooth it before conversion.

6.2 Plant B: atmospheric gas refinery

The gas side remains deliberately conventional:

1. weather-protected atmospheric intake;
2. filtration and salt-aerosol control;
3. staged compression and intercooling;
4. water, carbon-dioxide, and hydrocarbon removal;
5. main heat exchange and cryogenic refrigeration;
6. high- and low-pressure distillation columns;
7. oxygen, nitrogen, and argon product handling;
8. crude neon-helium fraction recovery;
9. rare-gas purification, analysis, and storage.

Seawater does not touch final process air. Direct water-piston compression may be tested as a low-pressure experimental stage, but it is not the base architecture. Separation protects product purity, controls corrosion, and lets the ASU be engineered and qualified using recognizable industrial practice.

7. Modular where repetition helps; centralized where scale helps

The original six-meter-wide intake package is plausible as a flow face. A 6.0 m by 3.5 m opening has 21 square meters of area; at 2.0 m/s, ideal face flow is approximately 42 m³/s, or 151,200 m³/h. Filters, louvers, weather protection, screens, duct transitions, and pressure losses must be added, but the geometric premise is coherent.

The mistake would be to interpret each intake as a complete independent neon factory. TideAir should modularize the repetitive edge of the plant and centralize the expensive thermodynamic core.

Repeatable modules:

• intake and louver banks;
• marine prefiltration and corrosion protection;
• isolation dampers;
• first-stage compression or blower skids;
• electrical substations and drive packages;
• tidal or current energy devices;
• hydraulic accumulators and power-conversion skids.

Shared process trains:

• final air compression;
• molecular-sieve pretreatment;
• cryogenic cold box;
• distillation columns;
• rare-gas enrichment;
• neon purification and analysis;
• certified storage and loading.

This hub-and-spoke topology allows a site to add intake and energy modules while retaining the scale economies and quality control of a central refinery.

8. The energy scale correction

Marine motion is dense and predictable, but neither quality makes energy free. The relevant question is how much head, flow, swept area, and time are available after conversion losses and environmental constraints.

A simple impoundment estimate for one tidal half-cycle is:

E ≈ 1/2 × ρ × g × A × h²

For a ten-meter-diameter shaft, area is approximately 78.5 m². With a ten-meter water-level change and seawater density near 1,025 kg/m³:

E ≈ 39.5 MJ per half-cycle
average over 6.2 h ≈ 1.8 kW before losses

That is useful for instrumentation, a pilot hydraulic circuit, or a teaching mechanism. It is not ASU-scale power.

For a one-square-kilometer impounded area under the same ten-meter range:

E ≈ 502.8 GJ per half-cycle
average over 6.2 h ≈ 22.5 MW before losses

This is the correct order of architecture. TideAir needs a resource measured in channel cross-section, turbine array, or basin area—not merely a picturesque collection of shafts.

A published cryogenic-ASU model processing 100 kg/s of atmospheric air reported approximately 21.8 MW of net power for its conventional configuration. [P30-S09] A 150,000 m³/h ambient-air module is roughly half that mass flow under ordinary conditions, suggesting an order-of-ten-megawatts process load before any site-specific design, product slate, pressure, liquid production, rare-gas equipment, or storage system is known. This is only a scale comparison, not a TideAir power forecast.

The corrected design conclusion is decisive:

Buoyancy shafts may be components of the power take-off. The primary resource must be a site-scale tidal-current array, lagoon, barrage, hydro system, or equivalent generation campus.

9. Why predictability still matters

The correction does not weaken the tidal idea. It clarifies its value.

The U.S. Department of Energy describes marine energy as highly predictable because waves, tides, and currents follow cyclic patterns, and it distinguishes theoretical, technical, and practical resource potential. [P30-S06; P30-S07] DOE also notes that marine technologies remain under development and face corrosion, cost, deployment, and permitting challenges. [P30-S08]

TideAir benefits from predictability in three ways:

1. Dispatch planning. Compressor loading, storage charging, maintenance, and grid purchases can be scheduled against known tidal windows.
2. Reserve-oriented output. Neon accumulation is inherently slow. The plant does not need every unit of product to leave the site the moment it is made.
3. Hybridization. A predictable variable source is easier to combine with hydro, nuclear, grid power, batteries, compressed-air storage, or thermal storage than an unforecastable source.

The invention is therefore not “the tide runs the plant at every instant.” It is “the tide becomes a forecastable component of the plant's energy contract.”

10. Multi-product economics

A standalone atmospheric neon plant fights the concentration of neon in every hour of operation. A multi-product ASU sells the major constituents and captures neon as a strategic side stream.

Linde's customized ASUs can produce oxygen, nitrogen, argon, krypton/xenon, and helium/neon, with large oxygen capacities spanning thousands of tons per day. [P30-S05] TideAir should therefore be financed and sited around a product stack:

• oxygen for metals, chemicals, wastewater, medical or energy applications;
• nitrogen for inerting, food, electronics, and industrial processes;
• argon for welding, metals, and electronics;
• neon as the strategic product;
• krypton and xenon where the scale and process configuration justify recovery;
• possible reclamation of neon-containing customer exhaust streams.

The local market for bulk gases may matter more to v1 economics than the neon price. This is not a compromise. It is the mechanism by which the rare product becomes supportable.

11. Storage and the reserve model

A strategic neon system is not merely a production line. It is a production-and-time system.

Linde offers compressed neon and refrigerated liquid neon, but liquid storage requires temperatures near neon's boiling point and is therefore a serious cryogenic choice rather than a default icon on a diagram. [P30-S16] A TideAir feasibility study must compare:

• high-pressure gaseous storage;
• liquid neon storage;
• purified intermediate storage;
• distributed cylinder or bundle inventories;
• customer-side reclamation and recycling;
• reserve rotation and purity surveillance.

The reserve needs rules: ownership, minimum stock, release triggers, geographic distribution, quality testing, and replenishment. A large central tank is not automatically more resilient than multiple qualified inventories.

12. Distributed Neon Geologies

TideAir is one member of a broader family. Distributed Neon Geologies means designing the production route around the local natural or industrial advantage that already performs part of the work.

12.1 Tidal and current regions

Use predictable marine power to support a conventional rare-gas ASU. This is TideAir proper.

12.2 Hydroelectric regions

Place rare-gas-capable ASUs near stable low-cost hydroelectric power and local oxygen demand. This may be less novel and more deployable.

12.3 Nuclear or geothermal baseload regions

Use high-capacity-factor heat and electricity where regional policy, safety, and economics support it. The atmospheric feedstock allows the plant to follow energy geography rather than mineral geography.

12.4 Curtailed renewable regions

Use wind or solar overproduction as one component of a hybrid energy contract, with the ASU scheduled and buffered rather than cycled recklessly.

12.5 Existing ASU secondary streams

Retrofit capture and purification onto large plants that currently discard or underuse rare-gas-bearing fractions. Linde explicitly describes plant concepts designed to increase capture from secondary streams in major ASUs. [P30-S03]

12.6 Helium and natural-gas processing

Assay helium-concentrate, nitrogen-rejection, LNG, and tail-gas streams for noble gases before venting, blending, or reinjection. Noble-gas studies show that natural gas reservoirs can contain radiogenic and nucleogenic helium, neon, argon, and xenon signatures. [P30-S12] This establishes geochemical possibility, not commercial neon abundance.

12.7 Cold-region reserves

Use cold climates for site operations and reserve logistics only where detailed thermodynamics show a benefit. Ambient Arctic cold remains far warmer than liquid neon and does not eliminate cryogenic storage work.

13. Russia as a bounded case study

Russia is useful as a case study because several enabling conditions coexist inside one border. It should not be treated as the preferred owner of another global chokepoint.

13.1 Existing helium-processing scale

Gazprom states that the Amur Gas Processing Plant has a design processing capacity of 42 billion cubic meters of natural gas per year and helium capacity up to 60 million cubic meters per year. [P30-S11] It also describes membrane extraction of helium concentrate at the Chayandinskoye field. [P30-S18]

This infrastructure suggests an assay opportunity: measure noble-gas composition across feed, membrane concentrate, nitrogen-rich streams, cryogenic offgas, and tail gas. It does not justify assuming that a profitable bulk-neon stream exists. Atmospheric neon is dominated by neon-20, while geologic studies often focus on small isotope anomalies—especially nucleogenic neon-21 and neon-22. A stream may be scientifically interesting and commercially irrelevant.

13.2 Penzhina Bay and high-range tides

Peer-reviewed hydrodynamic modeling has examined tidal waves and currents in Penzhina Bay in the Sea of Okhotsk. [P30-S13] Recent literature describes tidal heights up to approximately 13.9 meters and simultaneously emphasizes that the basin is an ecologically important subpolar system. [P30-S14]

That combination is exactly why a map is not a site approval. A high theoretical resource may still fail on ice, sediment, marine ecology, fisheries, community impact, transmission distance, construction emissions, logistics, geopolitics, or cost. The first deliverable must be a practical resource and environmental screen, not an architectural rendering.

13.3 The transferable lesson

The point of the Russian case is not “build the world's neon plant in Russia.” It is:

• assay existing gas-processing side streams wherever they occur;
• map site-scale predictable energy wherever it occurs;
• attach rare-gas recovery to regional bulk-gas demand;
• build reserves in multiple jurisdictions;
• refuse to replace one geopolitical dependency with another.

14. Peace technology without magical politics

The strongest version of the idea is modest enough to be true.

A distributed neon system cannot stop a government from invading another country. It can reduce the number of industrial systems whose continuity depends on peace at one border. It can make embargoes, sabotage, shipping interruption, and coercive price shocks less effective. It can give countries a practical alternative to controlling a source region.

Infrastructure contributes to peace when it lowers the reward for capture and the damage caused by disconnection. That is not a moral substitute for diplomacy or law. It is an engineering contribution to a world in which fewer essential functions are held hostage by accidental concentration.

15. Environmental and social constraints

A rare-gas-resilience project can become destructive if the “strategic” label is allowed to erase place.

Every TideAir site must account for:

• fish and marine-mammal movement;
• sediment transport and estuary morphology;
• water quality and dissolved oxygen;
• noise and vibration;
• ice, storm surge, and coastal flooding;
• corrosion and antifouling materials;
• protected areas and cultural sites;
• fishing, navigation, and local livelihoods;
• embodied carbon and construction logistics;
• emergency oxygen enrichment and cryogenic hazards;
• grid interconnection and transmission;
• decommissioning and restoration.

The preferred site may be an existing industrial waterfront, brownfield, port, dam, or energy campus where incremental impact is lower and gas customers are nearby. A pristine high-tide bay is not automatically a good site merely because the map is dramatic.

16. Evaluation program

TideAir should advance through gates that can kill or narrow the concept.

Gate 0: arithmetic and basis control

• define actual versus normal cubic meters;
• establish atmospheric composition basis;
• model uptime and recovery explicitly;
• remove any product rate not tied to a mass balance;
• establish the plant product slate.

Gate 1: resource-site coupling

• obtain tidal elevation and current time series;
• calculate theoretical, technical, and practical power;
• size generation, storage, grid, and ASU load on one hourly model;
• include ice, storms, maintenance, and transmission losses.

Gate 2: process simulation

• select a vendor-realistic ASU topology;
• calculate compressor stages, pressures, refrigeration, and product conditions;
• model crude neon-helium recovery and purification;
• produce sensitivity ranges for recovery and purity;
• quantify startup, turndown, and cycling constraints.

Gate 3: economic stack

• identify real local O₂/N₂/Ar demand;
• price electricity, marine infrastructure, cold box, purification, storage, and maintenance;
• compare TideAir against grid-powered ASU, hydro-powered ASU, and retrofit secondary-stream capture;
• value resilience separately from commodity margin.

Gate 4: environmental and institutional feasibility

• screen sites with communities and regulators before detailed design;
• model ecosystem effects;
• define ownership and reserve-release governance;
• map export controls, sanctions exposure, and semiconductor qualification requirements.

Gate 5: pilot

A credible pilot should not attempt a 600,000 m³/h campus. It should demonstrate one uncertain interface:

• marine power to stable industrial drive;
• hydraulic power take-off and buffering;
• assay and capture of an existing rare-gas side stream;
• neon purification from a purchased crude mixture;
• or an intake-module pressure-loss and marine-aerosol test.

17. Kill criteria

The architecture should be rejected or substantially narrowed if any of the following becomes true:

• local marine power has no practical advantage over ordinary grid or hydro supply;
• the best environmental site is too far from gas customers and transmission;
• rare-gas recovery adds unacceptable instability to the bulk-gas business;
• neon recovery is too low or purification too costly to beat diversified contract supply;
• marine infrastructure maintenance destroys the energy advantage;
• a conventional ASU retrofit delivers the same resilience at much lower cost;
• reserve governance creates another concentrated private chokepoint;
• community or ecological harm exceeds the strategic benefit.

A concept survives by becoming more specific, not by becoming harder to falsify.

18. Contribution

TideAir's contribution is not a new law of thermodynamics, a novel noble-gas chemistry, or a claim that tides alone make neon cheap. Its contribution is a systems composition:

Couple a site-scale predictable natural-energy resource to a modular-edge, centralized-core atmospheric gas refinery; treat bulk gases as the economic foundation, neon as a deliberate strategic co-product, and reserve time as part of the machine.

The larger contribution of Distributed Neon Geologies is a planning doctrine:

Do not search for one new neon capital. Build many regional pathways whose natural advantages differ but whose product and evidence standards interoperate.

19. Limitations

The paper uses public sources and first-order calculations. It does not contain proprietary ASU performance data, vendor recovery curves, a detailed process simulation, market forecasts, a life-cycle assessment, a site-specific tidal resource model, or legal analysis. The 150,000 m³/h intake threshold is reported from Linde's rare-gas production description and is not a universal engineering law. Power comparisons depend strongly on product purity, product pressure, liquid production, heat integration, climate, and process topology.

The Russian case study is bounded by publicly available information and does not assess present sanctions, ownership access, security conditions, or project feasibility. Geologic noble-gas isotope evidence must not be misread as proof of a commercial neon reserve.

20. Next work

The next artifact should be a transparent calculation model with four linked sheets:

1. atmospheric mass balance;
2. ASU energy and product assumptions;
3. tidal resource, conversion, and storage;
4. economics and resilience value.

It should compare at least four configurations:

• grid-connected conventional rare-gas ASU;
• hydro- or nuclear-powered ASU;
• TideAir lagoon/current campus;
• rare-gas retrofit on an existing ASU or helium-processing stream.

The next visual pass should render a real site plan only after the model establishes the required marine resource area, plant load, product storage, and environmental envelope.
