Publicly disclosed mechanisms are collected here because even a narrow invention represents somebody having already encountered, framed and attempted to solve a problem.
NASA Technology Transfer material is one of the principal sources under review. Entries are not endorsements and are not treated as drop-in components: each is examined for the problem it solves, its mechanism, assumptions, maturity and possible relationship to work elsewhere in Zenovka Labs.
Patent intake protocol
1 — Preserve provenance.
Record the original NASA or patent source, identifier, inventors and status before interpretation.
2 — Extract the useful mechanism.
Describe the engineering problem and the mechanism that makes the disclosure interesting without pretending the patent proves every claimed application.
3 — Cross-reference the bench.
Connect potentially useful mechanisms to Lab 01, agent systems or future studies, while clearly labelling adaptation and speculation.
4 — Keep rejected ideas.
A mechanism that does not fit the present design can remain useful evidence. The bench is allowed to accumulate parts before they have a machine.
Bench principle / read the constraint
A patent is also a record of what resisted.
The complete invention is only one scale at which a disclosure can be useful. Bearings, seals, thermal paths, deployment geometry, control methods and material choices often encode the constraints that forced them into existence.
For this bench, the question is therefore not only “can we use this invention?” but “what problem did its inventors have to solve, and does that problem exist somewhere else in the Station?”

Additively Manufactured Oscillating Heat Pipe for High Performance Cooling in High Temperature Applications
NASA referenceTOP2-316
Case numberARC-18625-1
Source centreAmes Research Center
Problem encountered. High-temperature structures need to move large heat loads out of geometries where conventional heat pipes introduce bends, welds and local structural weaknesses. Liquid-metal oscillating heat pipes can also suffer difficult start-up behaviour.
Mechanism worth keeping. NASA describes an oscillating heat pipe built directly into the structure by additive manufacturing. Interconnected capillary channels carry alternating liquid plugs and vapour bubbles. Refractory high-entropy alloys are proposed for the high-temperature body, while alternating channel diameters are used to help initiate circulation and address liquid-metal start-up behaviour.
Why it is on this bench. The most interesting feature is not simply “a better heat pipe”. It is the collapse of structure and thermal transport into the same manufactured object. That is relevant to any Zenovka system where a dedicated pipe network competes with mass, packaging or structural integrity. The alternating-diameter channels are also a useful example of geometry being used to solve a dynamic operating problem rather than merely a static packaging problem.
Possible Station relationships. Lab 01 already contains high-temperature heat-pipe assumptions around the CEU/RHU lineage. This disclosure does not validate those designs, nor should its claimed performance be transplanted into them. It does suggest a future comparison between discrete axial heat pipes and heat transport manufactured into a load-bearing shell. Station-scale thermal hardware may be an even cleaner application because it is less constrained by the hoverbike's serviceability and manufacturing assumptions.
Claimed NASA performance. NASA reports heat-transport capacity 10–100 times greater than the comparison technologies cited on the Technology Transfer page, along with passive operation and reduced vulnerability to failures associated with bends and welds. These are source claims, not independently verified Zenovka Labs measurements.
Status. Keep. No design adoption yet. The useful fragments are integrated manufacture, alternating channel diameter as a start-up aid, and refractory-alloy oscillating heat transport.

Research addendum / Feasibility ledger 001
Aegis / 02 September 2026
This ledger records what the external disclosure changes—and what it does not change—inside the Hoverbike concept. It is a comparison instrument, not a validation certificate.
- Concept claim
- The CEU-50 EFE revision 6.3 proposes a passive sodium heat-pipe array with capillary return and phase-change buffering, replacing an earlier pumped supercritical-CO₂ loop. The wider vehicle notes also identify thermal gradients, joining and vibration-tolerant refractory assemblies as limiting constraints.
- External evidence
- Disclosed mechanismNASA ARC-18625-1 describes additively manufactured oscillating heat pipes integrated into high-temperature structures, with refractory high-entropy alloys and alternating channel diameters intended to improve liquid-metal start-up.
- Supported inference
- Passive liquid-metal heat transport, refractory construction and geometry-led start-up control are credible areas for further CEU/RHU comparison. Integrating the thermal path into a structural shell may reduce joints and competing packaging mass.
- Not established
- The patent does not establish the CEU heat source, the Hoverbike’s complete thermal balance, sodium-array capacity, operation under the proposed vibration spectrum, phase-change protection time or whole-vehicle feasibility.
- Blocking work
- Define the real heat-load envelope; compare conventional wicked pipes with oscillating channels; model thaw and start-up transients; test orientation, acceleration and vibration effects; assess refractory-alloy joining, inspection, repair and thermal-cycle fatigue.
- Disposition
- Plausible extrapolationRetain as a candidate thermal architecture. Do not promote the internal numerical targets to validated values. Reclassify only when calculation or physical test evidence exists.
