Project Genesis: Coaxial RF-Solar Hybrid Power Infrastructure Part 2 Update - Inverted Cavity Receiver & Sealed Triskele TEG Architecture

Project Genesis Part 2 Update revises the Inverted Cavity Receiver from the original manifesto DOI 10.5281/zenodo.23761814. The original half-icosahedron geometric trap concept is retained, but three critical bottlenecks are de-risked for near-term fabrication: **1. Tiled Diamond Metasurface Flat Optics:** Replaces unmanufacturable 30cm bulk hyperbolic CVD diamond lens with 6x 100mm hexagonal diamond metasurface Fresnel flat lenses per triangular facet (k=2200 W/m·K). Retains <0.4% reflection with graded hybrid quartz impedance matching (n=1.54 to 2.41). **2. Sealed Triskele TEG Pod:** Core innovation. Standard TEGs lose 60-70% heat via edge leakage. This update introduces a 3-arm spiral (triskele) compliant thermoelectric leg inside a vacuum silica aerogel pod (k≈0.003 W/m·K) with Kovar edge seal. Cascade stack: skutterudite CoSb3:Yb (400-650°C) / half-Heusler ZrNiSn (200-400°C) / Bi2Te3 (80-200°C) with dimpled W/Cu thermal pillars (+30% area). Realistic recovery: 18-22% at ΔT=530°C (Tc=393K, Th=923K, Carnot=57.4%) — 2.5-3x commercial 5-8% modules. Previous claim of 55% is thermodynamically corrected (95% of Carnot). **3. Decoupled RF/Optical Paths:** Coaxial path is revised to spatially multiplexed but boresight co-aligned: central 80mm zone for 1064/1550nm optical (QD multi-junction) and surrounding annulus for 2.45/5.8 GHz RF (GaN Schottky rectenna) with FSS second-pass mirror for 90-92% capture. **True Range Analysis:** Single-hop >70% capture limits defined by diffraction θ≈1.22λ/D. Terrestrial 5.8 GHz 2m Tx / 3m Rx = 1-3km. Space-space 1550nm 0.3m aperture = 10k-50k km per hop. With Ghost Satellite Active Relay Constellation (re-collimation + 100W solar top-up), LEO-GEO = 1-2 hops optical, Earth-Moon 384k km = 8-15 hops (0.3m) or 1-2 hops (1.5m), enabling interplanetary scaling via hop count. Includes retrodirective phase conjugation tracking (3mm nose-cone pilot at 5.81 GHz + 5cm tail-redundant beacon), Edge AI demand-side signaling with TMR radiation hardening, and Tier 1-3 fabrication roadmap. Open Hardware: CERN-OHL-W v2. For peer review and prototype development. **Matrix Messenger:** David Michael Seagal / Michael Silver Collaboration **Location:** Hastings, Hawke's Bay, New Zealand
