The invention relates to hydroelectric power and can be used for capturing the energy stored in atmospheric moisture at any location in the world. The aim of the invention consists in increasing the functional possibilities and increasing the specific power of a hydroelectric power station by using a maximum possible drop in height between the head race and the tail race (from the height of condensation of atmospheric moisture to ground level). The main additional functional possibility of such an aero-hydroelectric power station consists in that it can operate virtually anywhere, whilst taking up a very small amount of space on the ground, and can even be mobile. Moreover, it makes it possible to produce, at any location, clean water for drinking and irrigation, without causing any damage to the environment as a result of comparatively small hydro flows. The device comprises a tail race (1), a head race (2), a water conduit (3), a turbogenerator (4), meshed, woven or film surfaces (5), a dirigible (6), and fastening cables (7). The dirigible (6) raises the surface (5) to a height above the dew point for these atmospheric conditions (usually this is 2 - 3 km). There, the supercooled atmospheric moisture starts to condense actively (starts to be collected) on the surfaces (5). A drainage system on the surfaces (5) directs this water away into a small reservoir (head race 2), from where the water, under the pressure of the total drop in height, passes along the water conduit (3) into the tail race (1) on the ground, thereby producing electrical energy in the turbogenerator (4).
