Is a man not entitled to the sweat of his brow? 'No!' says the man in Washington, 'It belongs to the poor.' 'No!' says the man in the Vatican, 'It belongs to God.' 'No!' says the man in Moscow, 'It belongs to everyone.' I rejected those answers; instead, I chose something different. I chose the impossible. I chose... Rapture, a city where the artist would not fear the censor, where the scientist would not be bound by petty morality, Where the great would not be constrained by the small! And with the sweat of your brow, Rapture can become your city as well.

Because of its narcotic effect at high pressure, nitrogen shouldn’t be breathed by humans at depths below about 60 meters. So, at 200 meters, the breathing mix in the habitat will be 2 percent oxygen and 98 percent helium. But because of its very high thermal conductivity, “we need to heat helium to 31–32 °C to get a normal 21–22 °C internal temperature environment,”
😮
So everyone is gonna sound like mice when they get crushed under the weight of the ocean?
Hmm... maybe not? The low density of helium at 1 atm is what causes the amplification of higher frequencies in the voicebox, but in a pressurized container the gas would be higher density so it might offset the effect... I think?
If the original SeaLab tests in the 60s were any indication, YES. Check out Scott Carpenter’s voice on this recording with LBJ. https://www.dailymotion.com/video/x3wkh6s
What they mean is they will need to use the amount of energy that you would normally put into air to get it to 31° C, but the helium will only get to 21° C. At no point will the helium actually be 31° C.
Will it be filled to the brim with billionaires so it can also malfunction and we are on time for the annual billionaire sacrifice to the sea gods?
So Bioshock….
Well, it's just scientists, so Sealab 2021.
Eventually, the techbros will make a cheaper version and add the pod to the end though.
as long as they don’t use a logitech controller i’m sure it’ll be fine
The logitech controller was fine, although it was questionable to be using a bluetooth one.
And in 2026, deep divers will be searching for datapads to find out what went wrong.
Build them as connectable hexagons. Learn from the insects, they've had a half billion years to figure out what shit works and what shit don't.
Sure when in air. Not so much for underwater or really anywhere where they have to deal with a pressure differential, either positive or negative, where large flat sides are detrimental.
The hexagon is only stronger than a circle if you're gridding it.
EDIT (stronger for the TOTAL material used)
If your looking for me
You better check under the sea
Cause that is where you'll find me
Underneath the
Sealab, Underneath the water
Sealab, At the bottom of the sea.
About 4 years late, but whatever.
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.
you should read michael chrichton's book sphere. it talks about some of the tom & jerry tier physics and biology disasters that can happen in a deep sea habitat
Yep I own a hardcover of it; fucking fantastic book, and excellent film adaptation.
high pressures are scary as shit.
apart from that, there's no sunlight down there. it's basically like living in antarctica.
If anything goes slightly wrong I die instantly you say? I need to sign up NOW
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.
What happened to biodomes? Did the Pauly Shore movie ruin the concept?
We never got them working properly here on earth, which isn't great news for a self sustainable moon or Mars colony.
One step closer to SOMA
I have an idea. Let's stick all of the world's billionaires into a submarine and see if lightning strikes twice.
I've been playing lots of Oxygen not Included, so... Yeah good luck, what could go wrong?
This is for the oil and gas industry.
Ain't nobody paying for an underwater habitat for researchers when all researchers do at depth is take photos and samples, which can be done by an ROV.
Oil and Gas OTOH need deep see divers to do welding and other maintenance all the time.
Watch our oceans die before your very eyes!
Ocean is tough. Tougher than floating cities. Which are more realistic as real habitable environment.
I vote for Stanford torus stations in various L points.
Or, naturally, Mars.
Before that, of course, there are plenty of locations on Earth hard to live in, but not as hard as underwater domes. They should try that.
The trouble with all these schemes is that it's totally contrary to poweful real world trends. The surface of the Earth has an overwhelming abundance of rural land that is incredibly hospitable to life. And these places are depopulating because people prefer living in cities. How are you gonna get people to move to the bottom of the sea, or Mars, if they don't even want to move to West Virginia?
The trouble with these commenters is that they don't read the articles. This one isn't at all about getting people to move underwater, it's very specifically about habitats for ocean researchers to live in, rather than spending enormous amounts of time decompressing after relatively short dives.
People don't really want to live in the cities they just want to live where they can get a job. Largely rural communities don't really have an overabundance of employment opportunities, tend to have crap internet, and most of the properties are already owned by rich people who want a second home, so house prices are completely insane.
