A submarine apparatus includes an internal bellows pipe that compresses and decompresses as the apparatus descends into and ascends within a water current. When the device is in a rising pressure process, water may condense inside a tube which may be collected in a tank. Water may also be condensed due to cold temperatures of the surrounding water and relative warmer air inside the AWS. The water may be used as a fresh source of water for drinking. Some embodiments include a generator assembly that generates electricity from a propellor move within the current. The electricity may be routed to powered components in the apparatus.

A watercraft and method for operating the watercraft, wherein the watercraft includes an electrical system that is present in a space that has an atmosphere that differs from air, where the space is formable by a pressure hull, where the atmosphere contains, for example, an inert gas, and where the space having the electrical system is filled with the atmosphere.

A passenger cabin air distribution system includes a ventilation system and an ejector-diffuser. The ventilation system is operable to provide a conditioned air. The ejector-diffuser is positioned to receive a flow of the conditioned air from the ventilation system. The ejector-diffuser includes an induction unit and a diffuser section. The induction unit includes a secondary inlet in communication with a cabin air from a passenger cabin and is configured to mix the flow of the conditioned air with an induced flow of the cabin air into a mixed air. The diffuser section includes a discharge to eject the mixed air to the passenger cabin. The diffuser section is shaped to provide for efficient mixing with low backpressure in order to maintain the low motive pressure in the nozzle.
