Very interesting to read, but sounds so astronomically expensive and reliant on zero mistakes in every single aspect of manufacturing every single thing going into the pods, that no one will sustain paying for this shit beyond angel investors.
Space is hard to get to, no gravity, and there's radiation.
Underwater has high pressure, corrosion, and no natural lighting.
When you get an air leak in space, you find the hole and patch it. When you get a leak underwater, you don't have to worry about it at all because it takes care of things in microseconds.
