Abstract: The invention relates to the field of agriculture, and more specifically, to plant growing installations and to multi-story (“vertical”) farms (20) for cultivating plants in artificial conditions. According to the invention, there is proposed a vertical plant growing installation (21) comprising: a lengthwise extended rack stack (1) having two bearing surfaces (1a, 1b) positioned at a small angle ? with respect to the vertical; two artificial soil sheets (3) securable to the bearing surfaces of the rack stack, each sheet being designed with a possibility of feeding thereto, and evacuating therefrom, a nutrient liquid and including at least a lower isolating layer (10), a water-retaining layer (11), a fertile layer (12), and an upper isolating layer (13) having perforations made therein; and two seeding sheets (4) comprising a plurality of seeds (4a) and placed above the artificial soil sheets, so as to provide contact between the seeds and the fertile layer of the artificial soil sheets.

Abstract: The invention relates to a multipurpose airship and, more particularly, to a hybrid dirigible. The airship comprises a body (2) having a parallelepiped shape and docking means (8) comprising four rods connected by a frame and designed to be extractable from the body (2), the ends of these rods being provided each with at least one vacuum cup for adhering to a substantially vertical surface of a building. The docking means (8) are provided with grips adapted to engage with the docking means (8) of another airship of the same design. The invention also relates to a set of airships including at least two said airships. The proposed airship does not require a lot of space for its takeoff and provides fast and secure evacuation of people from tower buildings. In addition, the invention provides the possibility of varying the airship payload directly in flight depending of specific needs.
