Abstract: A method and system for generating and spraying massive amounts of microscopic water droplets with moderate power consumption; according to said method and system a body of water is subjected to fast rotation, and to associated centrifugal acceleration, which gives rise to strong hydrostatic pressure forcing said water to pass through dense microscopic meshes, so that from each hole in said meshes emanates a micro-jets of water; said micro-jets of water keep accelerating in the direction of centrifugal force and break up into a cloud of said microscopic droplets; forced air flow applied to said droplets pushes them out to the free atmosphere; ultrasonic cleaning, integrated into the main operational cycle, removes deposition constituents from the surface of said meshes, preventing their clogging and possible disruption of generation of said water droplets.
