Because you're filthy rich and want to let all those pesky peasants know how much more valuable your rich life is, so much you can literally "survive underwater" while they suffer on the surface
Clarification: the bogus AI images they've got have windows in the viewing gallery. It's all bullshit though - it features the images from SAFE that are allso bullshit but keep popping up in various articles, notably* the MRI room.
That just means you're commenting on something without knowing anything about it, and so far everything you've commented has been incorrect?
It comes with two boats, jetskis, a helipad, and the ability to surface. You're not trapped in a hotel with no windows. It's not pitch black. You have ways to leave. It would have taken less time to learn this by reading the article than it would have taken to type this bollocks.
Nah, you were trying to shit on something and point out flaws with a hypothetical product wihout even bothering to read about it. You got called out on talking shite - don't take the hump.
This has already taken more time than it deserves from either of us. My criticisms were uninformed, sorry, I still think it's a shit idea. I don't want to stay in a hotel in which for significant portions of my stay I can't leave. I realise it's not really different from a cruise - I think cruises sound awful too, and this just adds on that some of the time you can't even go outside.
Not a nautical engineer, but those seem to be comparable to known military craft. That's probably a decent envelope for a sub carrying ordinance and full crew. So, lots of free space for a pleasure craft.
Range: approx. 15.000 km
To pump these numbers, that's likely surface cruising at some optimal speed. We can safely say this isn't a nuclear sub, since that would be something to boast: your "range" is really "how much food do you have?" since that runs out first.
Submerged duration: approx. 4 weeks
This one's tricky. There are ways to generate O2 without electricity. But the rest of your environmental controls like heat, light, plumbing, cooking, etc. draw power. So we can assume a pretty beefy battery bank on this boat, but not excessively so, in order to stretch into that 4 week range. But that's nothing revolutionary for subs - Electric subs go back to 1888, with diesel/electric hybrids coming along after that.
Depth: approx. 250 m
Totally plausible and shallower than military craft. But maybe not with the viewing windows in the illustration.
Considering that the record for longest continous submersion of a diesel-electric sub is something like 2 weeks, i highly doubt that 4 weeks in a civilian vessel is achievable
