Radiative Cooling of Any Sky-Facing Surface

John Roehling | 21-LW-006

Executive Summary

We aim to develop a material that cools sky-facing surfaces to tens of degrees Celsius below outdoor air temperature, day or night, without electricity. If successful, the material could reduce heatwave deaths in the world's undeveloped regions, minimize future worldwide energy demands, support disaster relief, enable water capture, and facilitate energy-efficient industry applications such as remote refrigeration.
