Congratulations to Bikram Bhatia for his work on passive directional radiative cooling. Using a directional approach to passive radiative cooling that exploits the angular confinement of solar irradiation in the sky, Bikram demonstrated sub-ambient cooling during the day regardless of the emitter properties in the solar spectrum. This work could enable low-cost radiative cooling systems and have applications in portable refrigeration and thermal management of concentrated photovoltaics.
