Experimental analysis of atmospheric heat sinks as heat dissipators
Maria Delgado,José Sánchez Ramos,María del Carmen Moreno,José Antonio Tenorio Ríos,Servando Álvarez Domínguez +4 more
TL;DR: In this article, a dual system in which water circulated either inside pipes or flowed down the outer surface of the collector was compared experimentally, for whereas the former has been analysed and assessed by earlier researchers, the latter has not.

Passive radiative cooling below ambient air temperature under direct sunlight
TL;DR: An integrated photonic solar reflector and thermal emitter consisting of seven layers of HfO2 and SiO2 that reflects 97 per cent of incident sunlight while emitting strongly and selectively in the atmospheric transparency window demonstrates that the cold darkness of the Universe can be used as a renewable thermodynamic resource, even during the hottest hours of the day.

Taming the blackbody with infrared metamaterials as selective thermal emitters.
Xianliang Liu,Talmage Tyler,Tatiana Starr,Anthony F. Starr,Nan Marie Jokerst,Willie J. Padilla +5 more
TL;DR: This Letter demonstrates, for the first time, selective thermal emitters based on metamaterial perfect absorbers and finds that emissivity and absorptivity agree very well as predicted by Kirchhoff's law of thermal radiation.
