Abstract

The thermal radiance from the clear sky is weak in the wavelength interval 8-13 μm. A surface material with high emittance in this wavelength interval will cool down to a temperature far below that of the ambience. Cooling powers of 100 Wm^-2 can be obtained at near-ambient temperatures. An appliction based on condensation of water from the atmospere is suggested. Initial tests show that about 400 g m^-2 can be collected in a single night.
