Abstract: The invention relations to hydroelectric power industry and can be used for capturing the energy stored within atmospheric moisture at any locations worldwide. The device comprises a tail race (1), a head race (2), a water conduit (3), a turbogenerator (4), meshed, woven or filmed surfaces (5), an airship (6), and fastening cables (7). The airship (6) raises the surfaces (5) to the altitude above the dew point corresponding to the given atmospheric conditions (usually, 2-3 km). There, are supercooled atmospheric moisture starts to condense (accumulate) actively on the surfaces (5). A drainage system provided on the surfaces (5) takes this water to a small reservoir (head race 2), from which the water, under a head caused by the entire altitude level difference, passes along the water conduit (3) into the tail race (1) on the ground, thereby producing electrical power in the turbogenerator (4).
