Joule Heist
Cold from heat — adsorption, solar-thermal, radiative, geothermal. The organizing question throughout is "what drives the pump?"
A deep cooling-technology reference compiled from a curated source library —
the physics, machines, working materials, and applications of moving heat out
of a space, with a bias toward heat-driven and passive cooling (adsorption,
solar-thermal, radiative, geothermal) that turns waste heat or the sky into
cold.
