The Science
How radiative cooling works
Nature-inspired technology that harnesses the coldness of space for sustainable cooling.
Solar Reflection
Our proprietary coating reflects up to 96% of incoming solar radiation, preventing heat absorption.
Infrared Emission
Emits thermal radiation in the atmospheric transparency window (8-13 μm), sending heat directly into the cold of outer space.
Passive Cooling
The combined effect creates net cooling of up to 30°C surface temperature reduction and 11°C sub-ambient chilled water generation.
