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.
