Various embodiments of a submerged submersible sailing vessel are disclosed. Such a submerged sailing vessel may comprise a submersible hull assembly, a keel coupled to and extending upwards from hull assembly towards a water surface, and a wind-catching assembly coupled to and extending upwards into the air from the keel for propelling the submerged sailing vessel. The hull assembly and the keel are submerged below the water surface as the vessel is propelled by the wind-catching assembly above the water surface.

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.
