In 2016 deep sea technology developer Dr. Phil Nuytten had a TEDx speech about his vision of an underwater habitat called Vent Base Alpha. It would generate the necessary energy from the geothermal vent next to its location and would consist of a 1bar environment. (Video length 19:08 min.)
I would like open the discussion of a 1bar habitat, all the difficulties and chances and add them to our concepts. Any proposals and ideas are welcome. Please use the comment boxes or e-mail.
