78-reflective-tunnel

The tunnel is sold as an engineering package: SPEC, segmented-assembly specification, CAD-parametric shape catalog, three variant hardware SPECs, IP references, sibling-portfolio cross-references, worked examples, runnable verification scripts, watertight STL meshes, and worldwide commercialisation rights.

A passive tunnel does not create energy — energy is conserved. What the tunnel does create is buildup: intracavity intensity proportional to the cavity Q (optical & microwave) or the reflector-boosted k-effective (nuclear). To exceed unity gain requires a gain medium inside the tunnel (laser / maser) or an externally-driven active source (klystron beam, fissile mass, etc.). Supplying that gain medium is out of scope for this project; the tunnel is dimensioned to accept common gain-medium form factors. The physics is textbook — Fabry-Pérot resonator theory, classical waveguide cavity Q, neutron reflector albedo — all more than a century of established results. The invention is the combination: the segmented-ring construction method, the three-variant lining table, the CAD-parametric shape family, and the hybrid-stack capability.

The construction method is Christopher Gabriel Brown’s segmented ring assembly. A ring is N trapezoidal segments joined edge-to-edge to form a polygonal cross-section that approximates a circle. The tunnel is a stack of such rings. Each segment carries the variant-specific reflective lining on its inner face. Length is arbitrary (add or remove rings). Cross-section is arbitrary (pick the ring diameter). Segments and rings can mix variants for a hybrid tunnel — an optical input stage, a microwave target stage, and a nuclear containment stage all in one stack.

The segmented ring assembly is scale-invariant in construction: the same segment / ring / stack method builds a cavity across nine orders of magnitude of length.

The optical variant is the direct engineering descendant of Patent 3561 (2017) and Patent 2486 (2017). Every segment’s inner face carries a multilayer dielectric mirror stack tuned to the operating wavelength.

Coating vendors (public commodity): Alluxa, Layertec, Optical Coatings Japan (OCJ), Newport.

The microwave variant provides the emitter-target coupling stage for the microwave-nuclear recycling family (patents 2495 / 2496) and the containment cavity for Solo Negative Microwave (project 49).

The nuclear variant is a neutron reflector geometry — the tunnel wall scatters incident neutrons back toward the tunnel interior. Applied around a subcritical or non-multiplying source, it boosts the effective neutron flux inside the tunnel by 1.3–2.0× over the bare configuration.

Reflector material vendors: Beryllium — Materion (US), Ceradyne. Nuclear-grade graphite — Toyo Tanso, SGL Carbon. Heavy water (D₂O) — Isowater (Canada), Cambridge Isotope.

A fully parameterised research-scale microwave-driven neutron-reflected target cell. Configuration H1 from the configurations catalog.

Every design number in this listing is reproduced by a runnable verification script (verify/verify_theory.py, 20/20 checks pass). The verification found and fixed two real documentation errors on its first run — that is the point of running the physics, not just quoting it.

Three independent-method reduced-order solvers in sim/simulate.py cross-check the closed-form theory:

FocusPhi is priced as a horizontal enabling platform — the shared reflective-cavity substrate under six portfolio products. Owning it is owning the concentrator / resonator / reflector primitive all six depend on.

All kits are Base, No IP — engineering package and worldwide commercialisation rights convey; the six founding patents are retained by the inventor. Reference on the bid catalog as row 58 ($100M headline). Included at no extra charge inside All In One (20T).

The underlying patents are retained by the inventor. Chris G Brown patents 3561, 2486, 2485, 2495, 2496, and 3457 (all 2017) remain the sole property of Christopher Gabriel Brown. This is a documentation + commercialisation-rights transaction — not a patent licence and not a patent assignment. If the buyer requires a patent licence or assignment, that is a separate transaction to be negotiated in writing.
