HEXFLOW Freezing Water. Hydraulic Force. Exploring water-ice expansion hydraulics for Mars and the Moon. HEXFlow investigates how water expanding as it freezes could displace a separate hydraulic fluid, producing a mechanical stroke for slow actuators or recovering work from water that must already freeze during processing. The white paper describes sealed cells, modular hydraulic networks, and potential planetary applications. Repeated operation requires both cooling to freeze the water and a warm interface to thaw and reset it. The proposed development path begins with small test cartridges, with larger modular systems explored as future research possibilities. Released by Planetary Energy Systems as a conceptual public disclosure to encourage further investigation, testing, and collaboration. Concept illustration shown.

🌕 BUILDING THE MOON’S FUTURE TRANSPORT NETWORKS LMSTCA — Lunar Modular Shielded Transit Corridor Architecture Factory-Manufactured Regolith Structures for Protected Lunar Transportation Networks What if future lunar settlements could connect their habitats, laboratories, and industrial facilities through protected underground transportation corridors? My latest conceptual engineering white paper explores an architecture for achieving this using lunar materials. The proposal combines factory-manufactured regolith structures, interlocking modular arches, robotic construction, and regolith shielding to create expandable transportation networks. Rather than pressurizing entire tunnels, the corridors would remain in lunar vacuum, with passengers traveling inside independently pressurized vehicles. The architecture also explores bio-inspired cellular regolith shielding and adaptable structural connections.

🌕 HELIOS RING — CONNECTED LUNAR SETTLEMENTS 🚀 What if the Moon’s future cities weren’t isolated bases, but part of one interconnected energy and transportation network? Introducing HELIOS RING — a conceptual circumlunar infrastructure system designed to combine solar power, autonomous freight transport, electrical distribution and lunar settlement development. ⚡ The concept: A solar-integrated railway extending approximately 10,900 km around the Moon, with roughly half the equatorial route illuminated at any given time. ☀️ Sunlit sections generate electricity. ⚡ An electrical backbone distributes power to settlements and infrastructure, including regions experiencing lunar night. 🚆 Autonomous trains transport cargo, equipment, resources and personnel between colonies. 🤖 Robotic maintenance vehicles inspect and clean solar arrays, particularly during low-light operating periods. 🏗️ Branch corridors connect the main ring to habitats, mining operations, industrial facilities and research outposts. As lunar civilisation expands, the network could expand alongside it, supporting new settlements through shared infrastructure rather than isolated systems. The vision is simple: More settlements → more connections → more infrastructure → a stronger lunar economy. Helios Ring remains a conceptual architecture requiring further engineering analysis, particularly for power transmission, construction and energy storage. But imagine a future where the Moon’s transportation network doesn’t just move civilisation. It helps power it. 🌕⚡ #HeliosRing #Moon #LunarInfrastructure #SpaceEngineering #SolarEnergy #SpaceExploration #LunarSettlement #AutonomousSystems #SpaceTechnology #FutureOfSpace

LETA — Lunar Electromagnetic Transport and Energy Architecture A systems architecture for shared lunar power, storage, electromagnetic transport, and launch. LETA explores how future lunar settlements could integrate solar generation, long-duration energy storage, pulse-power systems, industry, electromagnetic surface transport, and mass-driver launch into one coordinated energy architecture. The central idea is simple: generate energy gradually, store it intelligently, release it rapidly when high-power electromagnetic systems need it, and dynamically shift energy between survival, industry, and launch across the lunar day/night cycle.

Lunar Hybrid Electromagnetic and Rocket Launch Systems Vertical Well-and-Tower Launch Assist for Selected Moon-to-Earth Departures What if part of the energy needed to leave the Moon could be supplied by the Moon itself — before the rocket engines even ignite? This new conceptual white paper investigates a vertical electromagnetic launch-assist architecture: a spacecraft is lowered into a deep lunar well, accelerated upward through a stationary segmented electromagnetic system and tower with its engines off, then transitions to rocket propulsion after clearing the infrastructure. The study finds that the value of vertical launch is strongly dependent on mission geometry. In the nominal equatorial Moon-to-Earth case, a 1.4 km/s electromagnetic assist reduced modeled rocket propellant from 7.923 t to 4.806 t — a 39.3% reduction. Near the lunar south pole, the benefit was much smaller, showing that this is a conditional mission architecture rather than a universal replacement for conventional launch. The paper also examines the major unresolved challenges: multi-gigawatt pulse power, electromagnetic interface mass, superconducting and copper options, carrier recovery, thermal loads, civil engineering, shaft construction, delayed rocket ignition, and failure modes. This is a conceptual engineering study, not a claim of demonstrated feasibility — but the results suggest that selected Moon-to-Earth departure geometries may justify further investigation of vertical electromagnetic launch assistance.

LAUNCH ACOUSTIC METATERRAIN Exploring terrain geometry for launch acoustic control Could the ground around a launch pad help protect a rocket from its own noise? My newly published white paper investigates interrupted, ripple-like earthworks outside the protected launch core as a possible way to influence vehicle acoustic loading during ignition and early ascent. The research framework retains existing exhaust handling and water suppression, combining quantitative feasibility checks with a staged modelling and experimental programme. The first task is to establish whether modifiable terrain intercepts enough harmful sound to justify further development. This is a testable research proposal, with acoustic benefits still to be demonstrated. Read on Zenodo: doi.org/10.5281/zenodo.23073… Citation: Jaggard, S. (2026).

What if lunar freight wasn’t just about vehicles — but about building a moving energy corridor that follows the Sun? This illustration expands on Helios Highway by showing how daylight-following lunar road trains could be supported by solar farms, stationary battery reserves, powered charging sections, and robotic battery-swap nodes. Instead of relying only on onboard solar and battery capacity, freight vehicles could pass through dedicated energy nodes, slow down over powered rail sections, draw charge while moving, or exchange depleted battery modules for fully charged ones. The same solar infrastructure could also charge reserve packs in the final days of sunlight, allowing those stored batteries to help support nearby habitats through the lunar night. In that sense, the highway becomes more than transport infrastructure — it becomes part of a shared lunar energy system linking logistics, settlements, and surface industry. This idea builds on two of my published lunar transport concepts: JAGGARD, S. (2026). Helios Highway: A Daylight-Following Modular Lunar Surface Freight Network.

At what scale does lunar solar-thermal start to beat solar panels + batteries? For an early lunar base, photovoltaics are the obvious choice: simple, proven and modular. But a large industrial settlement changes the equation. Instead of importing ever-larger battery banks, could we manufacture simple heliostat mirrors locally, concentrate sunlight into a central receiver, store the heat underground in regolith or repurposed spacecraft tanks, then generate electricity through a closed-loop turbine during the lunar night? The interesting question isn’t whether concentrated solar power works — it does. It’s whether, at sufficient lunar settlement scale, locally built solar-thermal generation + thermal storage becomes cheaper, lighter and more sustainable than imported PV + electrical storage. That crossover point could be worth studying. #Moon #LunarEnergy #SpaceEngineering #EnergyStorage #ISRU @elonmusk @NASA @NASAMoonBase
