ABSTRACT
For instance, in the Hebrew bible, dew is mentioned many times such as in the Book of Genesis. People have indeed been long fascinated by dew, whereby small droplets cover the ground and plants overnight even though the sky is clear and rain clouds are absent. Soviet scientists just like their counterparts in France, Knapen and Chaptal, which had heard of the Zibold condenser, became interested again in the collection of dew water using this technique of massive condensers. Simple large planar condensers have been erected and more sophisticated dew plants made of ridges. Many other kinds of radiative dew condensers (conical-like, origami, etc.) were designed to increase cooling and dew drop collection. The interest of such radiative condensers is their simplicity, cost effectiveness, robustness (they can still work even partially damaged), and that no energy source is required.
