Looking as if it was plucked straight out of a sci-fi movie, the Sub-Biosphere 2 is an ambitious architectural concept created by designer Phil Pauley that is meant to be a submersible, sustainable, underwater environment. Created to house anyone from a scientist to a tourist, the architecture is made up of one large biome with eight surrounding domes connected to it.
The main sphere of the self-sustainable habitat comes equipped with an observation space along with technology to monitor vitals of all the separate pods. As the largest compartment of all the architectural bubbles, it is nearly 200 feet tall and almost 400 feet wide. The smaller domes also measure an impressive 200 feet wide by 100 feet tall and come attached with docking stations for ships to enter and tie down.
What may be the most interesting part of this project is the system's ability to submerge underwater for extended periods of time just like a submarine. Whether its function would be as a home for research scientists, an extravagant family vacation destination, or (in a slightly darker role) a long term human, plant, and animal habitat, the Sub-Biosphere 2 is intended to support all scenarios.
