Abstract:
1. An ecologically clean passive catcher of water-aerosols, wherein a streamlined wing-like blade is defined as a spatial-configuration having an asymmetrical streamlined contour, and wherein the upper side of said contour is longer than the lower side of said contour; and wherein said passive catcher comprising a set of at least two asymmetrically arranged stationary wing-like blades being exposed to humid wind bringing saturated water-vapors; wherein said asymmetrically arranged wing-like blades are oriented to act on said humid wind resulting in local varying of arriving air portions propagation direction and shape, wherein said varying shape having varying cross-section, thereby said varying direction and said varying cross-section providing local convective acceleration of said arriving air portions, wherein said local convective acceleration is accompanied by a local decrease in static pressure according to Bernoulli's principle; wherein said local decrease in static pressure is bonded with a local temperature decrease according to the gas state laws; such that said local temperature decrease triggers off condensation of said saturated water-vapors into water-aerosols and drops of dew, and said drops of dew collect upon surfaces of said asymmetrically arranged wing-like blades.
