The disclosure provides devices, methods, and systems for treating reactive metals and other reactive species produced during operation of thermal solid-state gas generators. Thermal energy, which may be derived from the gas generation process, physical contact with the evolved gases, or a dedicated or shared heat source, is used to release a gaseous species that neutralizes the reactive species. In some embodiments, the neutralization reaction causes the release of additional product gas(es).

A method for erecting the structure of an aerostat in successive horizontal sections, starting from the top horizontal section, comprising an iteration of the following steps, starting from a current state of completion of the aerostat structure, lifting the current state of the structure, at first lifting points, by means of lifting means arranged in a current transverse position; placing a support device in line with second lifting points for lifting the current state of the structure; transferring the current state of the structure from the lifting means to the support device; moving the lifting means to another transverse position; completely assembling the horizontal section immediately below the current state of the structure on the structure.

Overall efficiency and/or flight time of UAVs and Drones can be increased by adding elements containing lighter-than-air gasses; and/or by reducing and/or eliminating the power supplied to any combination of the motors to reduce overall power consumption. In an aspect the configuration of a blimp drone include at least one air cavity/chamber/container filled with lighter-than-air gasses. The 3D chambers are made from swept or extruded closed 2D geometry and are detachable from the Drone and can be transparent or camouflaged in color. To maintain control and altitude of the aircraft, lifting surfaces can be incorporated. Such lifting surfaces may include active and/or passive control surfaces to maintain flight stability. Additionally, cavities, fissures, orifices and valves may be added to the surface of the flying vehicle to gain other efficiency advantages.

Systems and methods related to deployable hydrogen reactors are described. In some embodiments, a system (e.g., a balloon system) may include a reaction chamber immersed in a body of water. By permitting a flow of water from the body of water into the reaction chamber, a reaction between a reactant and the water may be carried out to produce one or more lifting gases (e.g., hydrogen gas), which can be employed to subsequently inflate and launch the system in an automated fashion.

An unmanned aerial vehicle (“UAV”) having an envelope and a drone body capable of delivering packages is disclosed. Methods for utilizing UAVs to deliver packages and systems for housing UAVs are also disclosed. In one aspect, a UAV includes a dual cavity envelope having an ellipsoid shape with a first internal cavity and a second internal cavity, the first internal cavity configured to hold a lighter than air gas, the second internal cavity configured to hold a heated gas, and a drone body attached to and located below the dual cavity vertical envelope.

An autonomous unmanned aerial vehicle for land, sea and air use. The autonomous unmanned aerial vehicle is more specifically related to an unmanned aerial vehicle, wherein the autonomous unmanned aerial vehicle is configured to vertically take off and vertically land, fly with fixed wings and stay in the air silently for a long time by means of a balloon inflated behind it.
