Abstract
Global infrastructure analyses identify ten critical thermodynamic gaps beyond the first 40 worldwide gaps: global food cold‑chain stability, EV fast‑charging cooling, atmospheric micro‑plastic capture, water‑distribution thermal stability, autonomous‑vehicle compute cooling, emergency drone cooling, remote medical‑clinic cooling, agricultural‑chemical neutralization, rural edge‑compute cooling, and robotics cooling in extreme environments.
This disclosure presents a unified thermodynamic upgrade engine composed of gyroid thermal‑hydraulic cores, TPMS purification lattices, vortex‑TPMS cooling modules, atmospheric water harvesters, micro‑particle capture lattices, chip‑scale cooling engines, radiative gyroid condensers, and auxiliary subsystems.
Each subsystem is explained in detail, including how it directly fills a global gap, how it works, and how it can be built. Includes full architecture, BOM, build path, test protocol, physics rationale, performance analysis, alternate configurations, simulation notes, and a global deployment roadmap.
This disclosure is intended as open‑hardware prior art to ensure global public access.
