TL;DR: Polyethylene aerogel (PEA) is developed—a solar-reflecting, thermally insulating, and low-thermal-conductivity material that can be integrated with existing emitters to address the challenges of passive radiative cooling under direct sunlight.

TL;DR: A directional approach to passive radiative cooling that exploits the angular confinement of solar irradiation in the sky to achieve sub-ambient cooling during the day regardless of the emitter properties in the solar spectrum is shown.

TL;DR: In this paper, a dual-stage solar-thermal-driven atmospheric water harvesting (AWH) system with optimized transport is proposed to recover the latent heat of condensation of the top stage and maintain the required temperature difference between stages, enabling higher daily water productivity than a single-stage device without auxiliary units for heating or vapor transport.

TL;DR: In this paper , the authors demonstrate highly efficient (>80% solar-to-vapor conversion efficiency) and salt rejecting (20 weight % salinity) solar evaporation by engineering the fluidic flow in a wick-free confined water layer.

TL;DR: In this article, the authors demonstrate a passive solar thermal device mostly built from low-cost off-the-shelf components capable of delivering saturated and pressurized steam to drive sterilization cycles even under hazy and partly cloudy weather.
