Alternative and pollution-free way of producing water

Abstract

The purpose. To assess an opportunities of alternative way of deriving quality water from aerosphere. Methods. Analytical, calculation. Results. The share of fresh water on the planet makes 2,5% of its general amount. Fresh water is concentrated mainly in ice cellars. Only 0,1% of fresh water is in circulation. Almost 86% of all water volume that enters in aerosphere of the planet is water of oceans and seas. Accordingly 73,5 thousand km3 make volumes of vaporization from the surface of land. 36 thousand km3 of them are water volumes, which enter in air as the result of processes of thermal control of plants (transpiration). The majority of regions of the country receive water from aerosphere as the result of advection (transference) of water vapour from open spaces of oceans, seas, surfaces of fresh ponds in depth of continent and its storin evapotranspiration or snow. Conclusions. Power expenditures for deriving water can be diminished in some times at use of system of heat exchangers with low temperature of substrate (cool water, rock, etc.), which effectively absorb warm from air and warm change of phase of vapour into fluid.
