Heat-driven and passive cooling: adsorption, solar-thermal, radiative, geothermal.

A knowledge base on cooling technology with a bias toward heat-driven and passive cooling — systems that run on waste heat, sunlight, or the cold sky rather than grid electricity through a compressor. Covers adsorption, vapor compression, solar thermal, radiative/black-body, geothermal, heat pumps, and supporting threads from CO₂ to desiccants to hydronics.
