It only took 2,000 years

SkyCool harnesses a natural phenomenon that was first used thousands of years ago to make ice at night in the desert. Using materials science and mechanical engineering in a lab at Stanford, we created radiative cooling products that work 24 hours a day, without electricity. Our discovery led to one of the most cited papers in Physics, and a killer TED Talk.

Two New Paradigms in Cooling

SkyCool's products can change how you cool your buildings and systems.
