Geometric Blackness — Shape-Based Light Trapping 2026-09-25

Geometric blackness is the principle of trapping light with shape rather than pigment: angled cavities catch incoming light in repeated reflections so a surface absorbs almost ever…

Radiative & Black-Body Cooling — Surfaces That Move Heat by Light 2026-09-25

The surface physics of moving heat by radiation, enabling two cooling moves: rejecting heat by emitting it to the cold sky (Purdue's BaSO4 paint: 98.1% reflectance, 0.95 sky-window…

Solar Thermal — Collectors That Drive Cooling 2026-09-25

Solar thermal is the heat supply for sun-driven cooling, delivering desorption heat to an adsorption chiller with the key virtue of coincidence between peak insolation and peak coo…
