Abstract

The Harmonic Rescue Lantern (HRL) is a grapefruit‑sized, passive, quasicrystalline survival device designed to increase human survivability in aquatic and terrestrial emergencies without requiring power, electronics, fuel, or moving parts. The HRL integrates a hollow icosahedrally derived quasicrystalline shell, a tension‑balanced internal lattice, a passive acoustic resonator, and a thermal boundary‑layer geometry to provide four simultaneous life‑supportive functions: omnidirectional optical scattering, enhanced acoustic signaling, buoyant high‑visibility flotation, and localized thermal stabilization.

The HRL is optimized for oceans, lakes, rivers, streams, and floodwaters, where conventional signaling tools often fail due to battery loss, corrosion, or mechanical damage. Any available light source—sunlight, moonlight, vessel lighting, or flashlights—produces a 360° scattering signature. Simple tapping or blowing generates a resonant, far‑carrying acoustic tone. The structure remains buoyant and visually trackable in rough water, and the geometry slows heat loss when held against the body.

The HRL draws conceptually from several prior Caldwell metamaterial inventions—including the Icosahedral Quasicrystalline Monolith (IQM), Dyneema‑inspired tension lattices, bio‑harmonic thermal envelope concepts, and thermo‑resonant testbeds—while forming a new humanitarian class of portable, non‑military survival technology intended for open scientific study and global life‑saving deployment.
