A device for extracting fresh water from atmospheric air is as follows. Tanks 1 made of light material, for example polypropylene, are located one above the other (Fig. 1, 2). Each container is made in the form of a body of revolution with a bell 2. In the lower part, each container contains a cylindrical spring corrugated insert 3. In each container 1 in its upper part there is a cover 4. The base of each container, located below the upper one, is mounted on the cover of the container located below . In all containers in the lid on the side there is an outlet with a check valve 5, allowing air to escape. In the center of the lid 4 there is a central hole 6 for passing air into the container 1 ′ installed above and made similarly to the container 1. In the upper container, the air from the central hole 6 exits. In the lower part of all containers 1 there is additionally an inlet 7 located inside the container at its bottom with an edge and connecting adjacent containers located one above the other. The hole 7 in the lower tank is connected to the outside air. The inlet 7 ends with a side tube 8 (Fig. 2), which discharges air so that it moves in a circle along the inner surface of the corrugated insert 3. The opening of the side tube 8 has a check valve 9, which prevents air from flowing in the opposite direction. The throughput of the hole 7 is much greater than the throughput of the hole 6 and the hole 5 with a check valve. Above the openings 6 are installed teardrops 10 made of foil, the plates of which are parallel to the axis of symmetry. Under the teardrops 10, funnel-shaped water collectors 11 are installed with tubes 12 extending along the axis of symmetry along the containers 1. The total number of containers located one above the other depends on humidity and temperature in this place. Under the lower tank there is a common tray 13, made in the form of a bell 13, facing the expanded part down and resting on a trellised base 14 attached to the surface 15. The surface of the trellised base is equipped with a common sump 16.

Each tank 1 has a cavity 17 filled with gas whose density is lower than atmospheric. This cavity surrounds the container in the area of the socket 2.

The upper tank 1 ′ using a cable 18 (Fig. 3) is connected to a balloon 19 filled with gas, the density of which is lower than atmospheric. The balloon 19 has an aerodynamic profile consisting of a flat surface 20 and a convex spherical surface 21. The convex surface 21 is oriented downward. The cable 19 is attached to the upper tank using a strapping 22, covering the upper part of the upper tank together with the cavity 17. The cable 18 in the lower part has a ring 23 to which additional side cables 24 are mounted, which prevent the swaying of the total package of containers 1 during lateral winds.

In an embodiment of the technical solution, the upper surface of the aerostat 1 is provided with a visor 25 (Fig. 4, 5) that extends beyond the perimeter of the upper surface, which gives the apparatus an asymmetric shape. The visor is made of lightweight plastic material and has a small thickness, and its plane is a continuation of the upper surface 20.

In a variant of the technical solution, a balloon is installed above the balloon, filled with gas having a density lower than atmospheric, and connected to the device using a rail (not shown).

A device for extracting fresh water from atmospheric air operates as follows. Due to the fact that the balloon 19 is lighter than air, it rises above the surface of the earth to a certain height, determined by the length of the cable 18, and pulls a package of containers 1. This cavity is facilitated by cavities 17 (Fig. 3). When exposed to the aerostat 19, the air flow due to the aerodynamic effect, depending on the difference in the speeds of the wind flows around it from the upper surface 20 and the lower surface 21, will tend to move down. Thus, two forces act on the balloon, one of which tends to raise it up, and the second to lower it. Moreover, the whole system 19 will oscillate up and down. If there is a visor 25 (Fig. 4, 5) during movement under the influence of wind downward, a unilateral air resistance force directed vertically will act on the visor 25. The device will turn sideways with respect to the wind, which weakens the effect of the aerodynamic effect. The device will begin to rise again, trying to take its original position. Next, the process will be repeated. Due to this, an additional change in the balance of forces acting on the tank will occur, even with a constant air flow. As a result, the oscillatory process will occur more intensively, which will increase the energy return of the system.

Oscillatory movements are transmitted through the cable 18 to the package of containers 1, which will be stretched or compressed due to corrugated inserts 3, which will lead to a change in the internal volume of the containers. When expanding in the tank through the check valves 9 and openings 7 (Fig. 2), external air from the lower tank and then throughout the package will enter the cavity. This air stream will rotate along their inner surfaces. If the balloon 19 will move down, then the air in the containers 1 will be squeezed out due to the spring forces of the corrugated inserts 3. As a result, the air flow in the containers will move in a spiral. Due to the Rank effect, the layers of air moving inside the spiral will be colder than the peripheral ones. Moreover, the higher the capacity, the lower the temperature of the air moving inside. Peripheral, warmer layers of air will exit through openings 5, while internal cooler layers will move upward through openings 6 from one container to another located above. And the higher the capacity of 1, the lower the temperature of the air in the tank. At a certain temperature, the moisture present in the air will be released in the teardrop 10, collected in the sump 11 and drained through the tubes 12 into a common sump 16 (Fig. 1).

To increase productivity, it is desirable to place the device in places with high humidity, for example, on the shore of a reservoir.

A feature of the device is that it is made of simple and lightweight materials, does not require additional energy and is able to work autonomously in various climatic conditions and around the clock.

The presence of several containers in series located one above the other to collect moisture, with a bell and a top cover, improves the productivity of the installation.

Cylindrical spring corrugated inserts in containers provide automatic operation of the device for air rotation.

The presence in all containers in the lid on the side of the outlet with a check valve that allows air to escape, allows you to separate warmer air from cold air.

A central opening for letting air into the container installed above in the center of the lid allows you to use cooler air to create a dew point and collect moisture.

Inlet openings with side tubes at the bottom of all containers, located on the bottom with the edge and connecting adjacent containers located one above the other, allow air to be introduced so that it moves clockwise, in a circle, along the inner surface of the corrugated insert, which makes it possible to partially differentiate the air into a warm peripheral and colder in the center.

Teardrops made of foil in the form of plates and mounted above the central holes with funnel-shaped water collectors and tubes passing along the axis of symmetry along the containers, allow moisture to be concentrated and collected under a lower tank in a common water collector.

The presence of a cavity filled with gas, whose density is lower than atmospheric, encircling the container in the area of the bell, reduces the load on the balloon.

The aerodynamic profile of a balloon made in the form of a body is lighter than air with lower spherical and flat upper surfaces, provides an oscillatory process of movement of the device’s tanks. This is facilitated by the presence of a visor that extends beyond the perimeter of the upper surface,

A balloon filled with a gas having a density lower than atmospheric, connected to the device using a rail and mounted above the balloon, increases the levitation properties of the device.
