Research & development: The heartbeat of innovation

Welcome to the forefront of our work at The SCG-HMH Generator and TITAN Starship Concepts. This page details our ongoing research and development, inviting you to explore the ambitious projects that are shaping the future of sustainable energy and propulsion. Join us as we push the boundaries of what is possible.

The SCG-HMH Phase-1 prototype: The core challenge

Our most exciting project currently is the SCG-HMH Phase-1 Prototype. This initial build focuses on a critical question: Can the mechanical-cryogenic core of SCG-HMH function as a real machine on a bench? Before we explore plasma conductivity, MHD extraction, or even starship concepts, we must prove three fundamental elements:

  • Quantum (flux-pin) levitation: Demonstrating a YBCO HTS bearing pair, quenched in liquid nitrogen (LN₂), that securely holds and centres the rotor without rubbing contact.
  • High revolutions per minute (RPM): Achieving stable spin of a compact vertical rotor (targeting 0.2 m diameter × 0.4 m tall, Ti-Be/CFRP architecture), gradually stepping up to design point against hoop-stress and burst margins.
  • Nozzle jet propulsion: Producing measurable thrust/specific impulse from LN₂ phase-change expansion through a De Laval nozzle (design expansion ratio 694:1), acting as a cold-gas/two-phase jet.

Success in these areas forms the bedrock for all subsequent layers of the generator, confirming the viability of our foundational design.

Solving real-world problems and opening new frontiers

Our primary goal with Phase-1 is to develop a working machine that unequivocally proves the core concepts: flux-pin levitation in LN₂, a robust high-RPM rotor, and a nozzle that generates measurable thrust from nitrogen expansion. Once proven, we can incrementally add the full generator stack, including heat input, ReBCO stators, cold plasma, and hybrid magnetohydrodynamics (MHD), leading to a modular cell capable of generating useful power from low-grade heat.

This research addresses a critical oversight in current energy and space systems: the conventional disposal of waste heat. SCG-HMH uniquely integrates heat, LN₂, spin, and plasma into a single, efficient loop. On Earth, this translates into a practical solution for converting data centre and industrial waste heat into electricity, simultaneously providing cooling. In space, the same loop leverages the 2.7 K cosmic background as a heat sink, allowing computing, power generation, and cold-gas/high-expansion jet propulsion to share a single cryogen. This integrated approach redefines waste as a resource, unlocking unprecedented possibilities for energy efficiency and sustainable operation.

Who we are looking for: Researchers, collaborators, and curious minds

This page is designed to engage a diverse audience. We are seeking:

  • Researchers: Those who can rigorously stress-test the thermodynamic, HTS bearing, two-phase nozzle, and future cold-plasma/MHD claims. We welcome critique, replication efforts, and data suitable for a lab notebook.
  • Collaborators: Labs and workshops with expertise in cryogenics, rotor dynamics, ReBCO/YBCO materials, nozzles, instrumentation, and safety. We are also looking for partners to host benches, provide LN₂ practice, or fund the initial containment and thrust stand.
  • Curious minds: Anyone interested in following the public story of our project, witnessing a generator built layer by layer without hype. All drawings and a transparent "not proven yet" list will remain visible.

For Phase-1, our highest priority is to connect with builders and experimentalists.

Join us in shaping the future

We want you to understand that the universe remains generous. Physics permits machines that levitate on flux-pinned superconductors, spin at high RPM in a cryogenic vapour path, and convert heat into power through nitrogen expansion and a nozzle—machines that can evolve into factories and starships. This is not a mere dream; it is a meticulously crafted build list. We invite you to be hopeful, excited, and ready to contribute.

The SCG-HMH is an open cryogenic architecture, with LN₂ serving as the working fluid, coolant, dielectric, and eventually, plasma medium. It features a compact rotor on YBCO flux-pin bearings, followed by ReBCO stators, cold non-equilibrium plasma, hybrid MHD, TITAN's magnetosphere, Guardian biology, and further theoretical layers. None of this represents a finished starship; Phase-1 is the crucial first heartbeat—quantum levitation, high RPM, and nozzle jet—upon which the generator stack will be incrementally built.
