Abstract: The invention provides wind energy use. One application provides wind energy use for water harvesting from natural humid air. The method is based on changing thermodynamic state parameters of ambient wind air portions passed through a device comprising convergent-divergent and wing-like components.

The electrical energy harvesting mechanism is also applicable to use of natural renewable energy of streaming water.

Abstract: A method and an apparatus are described to focus sharply a wide range of particle sizes for particles suspended in a relatively high flow rate of carrier gas. The particles are accelerated through a continuously converging ladder of smooth contractions, each designed such that: (i) the flow remains laminar at substantial Reynolds numbers; (ii) a certain band of particle sizes is focused in each contraction, without substantial defocusing of larger particle focused in one or several preceding contractions; (iii) the form, length, and ratio of entry to exit diameter of each contraction, as well as the number of consecutive contractions are chosen such that all particles within a given relatively wide range of sizes are focused at the end of the ladder of contraction steps into a relatively narrow focal region. The focusing apparatus coupled to a collector device constitutes a new type of virtual impactor, termed a focusing virtual impactor, which can also be used as a powerful particle concentrator.

Abstract: The invention provides an ecologically clean method and apparatus for water harvesting from air. The method is based on changing of thermodynamic state properties of air wind getting a rotation and passing through convergent-divergent nozzles. The apparatus is a water condensation engine exposed to humid wind. The constructive solution has no moving solid parts, and the incoming wind is an inherent moving component of the engine. It comprises a cascade of sequentially arranged horn-tubes and a set of stationary wing-like details. Those horn-tubes transform the wind into a fast and cooled out-flowing air flux coming-and-hitting upon the set of wing-like details, where the air portions are accelerated and eddying. The inner static pressure and temperature decrease in the air portions. The decrease in static pressure and temperature triggers off condensation of water-vapors into water-aerosols.
