A hydrogen storage tank for a hydrogen fueled aircraft. The tank has a wall made of layers of aerogel sections around a hard shell layer, sealed within a flexible outer layer, and having the air removed to form a vacuum. The periphery of each layer section abuts other sections of that layer, but only overlies the periphery of the sections of other layers at individual points. The wall is characterized by a thermal conductivity that is lower near its gravitational top than its gravitational bottom. The tank has two exit passageways, one being direct, and the other passing through a vapor shield that extends through the wall between two layers of aerogel. A control system controls the relative flow through the two passages to regulate the boil-off rate of the tank.

A valve for use in a tank vessel that includes a valve housing configured to fit into a threaded vent opening of the tank vessel and a sleeve weldment coupled to the valve housing. The sleeve weldment includes a first end configured to protrude into an interior volume of the tank vessel, and the first end is thermally balanced with the interior volume of the tank vessel. The valve also includes a valve plunger configured to be installed within the sleeve weldment. The valve plunger includes a valve bottom configured to seal an opening between the valve bottom and an interior opening of the sleeve weldment. The valve also may include a cam configured to force the valve plunger into the interior of the tank vessel to break the seal between the valve bottom and the interior opening of the sleeve weldment.

An Automatic Service Station Facility (ASSF) for replenishing various motivational energy sources onboard different types of AUV, Drones, and Remotely Controlled (RC) or robotic vehicles is disclosed herein. In one embodiment, the automatic service station facility includes a rack, replaceable fuel tanks, a service module, and an electronic computer control system. The replaceable fuel tanks are stocked on the rack and substantially filled with various fluids which are utile as motivational energy sources within fuel-operated vehicles. The service module is mounted on the rack, and the electronic computer control system is connected in electrical communication with the service module. In this configuration, the service module is controllably operable to receive a depleted replaceable fuel tank from a fuel-operated vehicle and also selectively deliver one of the filled replaceable fuel tanks onboard the vehicle. In another embodiment, the service station facility may also stock replaceable batteries for selective delivery onboard battery-operated vehicles. In another embodiment, the ASSF is self-propelled, remotely controlled, and solar powered, being able to move long distances to remote locations which may be hazardous to humans, such as disaster zones or battle fields, where the ASSF can service AUV, Drones, and Remotely Controlled (RC) or robotic vehicles needed for the particular applications. Alternatively, the solar powered ASSF can be made to move continuously and service vehicles continuously for long duration operations like herding cattle for example.
