A structure with a foam foaming device for geoengineering is characterized by (A) having an effective relative velocity difference with the atmosphere so that the desired location of the structure in contact with the atmosphere can generate turbulence that decomposes foam, and (B) being capable of maintaining an effective relative velocity difference with seawater so as to be able to generate wake waves that decompose foam which has fallen to the surface of the water from a foam outlet. In one embodiment, the structure is a ship.

A stratospheric airship includes a nonrigid balloon equipped with a solar generator arranged on the upper part of the nonrigid balloon intended to be illuminated in flight by the sun, the airship comprising: at least one device for managing the position of the centre of gravity of the airship; at least one device for stabilizing the attitude of the airship; and a module for the coupled control of the devices, configured to control the airship, when the speed of travel of the airship with respect to the surrounding air is below a first threshold (S1) and/or the temperature of the solar generator is above a second threshold (S2), in such a way that it rotates by substantially half a turn about its longitudinal axis (AL), so as to protect the solar generator from illumination by the sun.

An aerial vehicle control system includes an aerial vehicle and a computing device. The aerial vehicle includes an altitude controller and a lateral propulsion controller The computing device includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the computing device to obtain location data corresponding to a location of the aerial vehicle; obtain wind data; determine an altitude command, a latitude command, and a longitude command based on at least one of the location data or the wind data; cause the altitude controller to implement at least one of the altitude command, the latitude command, or the longitude command; and cause the lateral propulsion controller to implement at least one of the altitude command, the latitude command, or the longitude command.

A reusable floating device suitable for launching a space rocket has a support structure which includes a toroidal balloon housing and a rigid platform attached thereto; an elongated rigid structure surrounded by said support structure, releasably connected thereto, and adapted for attachment to a space rocket; at least one buoyant gas balloon within said balloon housing; and a compressor module and at least one rigid-walled tank carried by said platform. The compressor module is in confined flow communication with the at least one buoyant gas balloon and the at least one rigid-walled tank.

A lighter-than-air toy drone assembly that stays aloft using a balloon that is filled with a lighter-than-air gas. The balloon is inflated and deflated with the gas through a remote control vent valve. A ballast chamber can be provided that is filled with and drained of ballast through a purge valve. Controlled flight is achieved by selectively controlling motorized propellers, the vent valve and the optional purge valve. The motorized propeller provides horizontal movement. The purge valve and the vent valve change the buoyancy of the drone assembly and therefore control vertical movement.
