omg, that merman Simon graphic in the end-credits was a hilarious surprise haha! ^_^ On topic tho, I'm genuinely surprised that more effort hasn't gone into oceanic settlements. As China's island-building (and, to a lesser extent, Saudi Arabia's commercial island building) has shown, it's a fairly simple way to artificially inflate your borders, create usable territory, or just extend your military's reach. Even some of the surface-oriented sea-steading proposals (that are FAR less damaging to the local ecosystems than dumping tons of stuff to build an island) could go a long way to alleviating the impact of sea-level rise that's already threatening several island nations.

It occurs to me that there is a third alternative beyond just space or underwater, and that is underground - we definitely have a lot of ground to go under! It's more accessible than underwater, more maintainable than underwater, much safer than underwater (but not entirely without risks if you count cave-ins), no adjustment is needed when coming back above ground (apart from getting used to daylight I guess), it's relatively easy to expand the habitat, and we already have all the equipment needed to construct such habitats. Heat and drinkable water is already there too. Plus there are already hundreds of caves around the world that could be utilised if drilling/excavating isn't preferred. Human cultures have lived underground before, and we could do it again. Only better.

[@bonefetcherbrimley7740]

Yes! And we could build cool hobbit homes.

[@projectdeveloper9311]

Actually pressure is still a problem, but only if you go really deep (500m below ground), because the air pressure difference is enough to cause harm (don't ask me what or how), and I only know that because a coal miner wrote how he and his crew almost died because a newcomer had a panic attack in the decompression chamber and tried opening the door

[@Lodrik18]

But you can use the tides to generate energy in underwater and doesnt really work underground. My understanding of mines also suggests that the dust created in tunneling/your cave expansions is highly explosive and lastly we started out with the problem that real estate is shrinking because of global warming so lots of caves are going to flood too (rising tides and floods)...

[@AdrianWright6363]

@@Lodrik18 I agree that there is energy from currents underwater, but probably far more energy within the ground. Some caves would doubtless lie below some flood levels, but many wouldn't. The problem with living underwater is it's complicated to get back to the surface (limited space on vehicles, decompression etc.), whereas going back to the surface from living underground is just a matter of walking.

Living ON TOP of the water is a more feasible concept, and not even mentioned.

I think it will ultimately come down to costs and risks... artificial islands and floating cities are currently cheaper and carry fewer risk of fatalities.

As a person who believe that intelligent life exists in space somewhere other than earth, I find it to be almost as (or maybe more so) likely that intelligent life exists "underwater". 3/4 of the earth is basically unexplored, and it is teaming with life that has yet to be discovered. Because I believe intelligent life exists in space (where I see no proof of any life), I have to believe that intelligent life is underwater on a planet where intelligent life exists on dry land. Intelligent life came from the sea, from what I've been taught. UFO's seem attracted to the sea (yes, I went there, the most credible ufo sighting was seen hovering over the ocean seemingly communicating with something underwater (the tic tac video that 4 highly trained navy pilots all witnessed from two different planes)). No coincidence the military has renamed UFO's to UAP's. Unidentified Anomalous Phenomena. The military is using their verbage to include underwater UFO's. They aren't flying, they're swimming. UFO is obsolete in that case. F stands for flying.

[@ukmediawarrior]

So how do these habitats deal with rising sea levels? I mean, ok, you build one 10 meters down, but as the sea levels rise would it not fail badly as pressure grows? And those that have a level on the surface of the sea would find that level slowly being overwhelmed as the sea rises.

[@mill2712]

Just took a Google search. If all the earth's ice caps melted, the oceans would rise by 60 to 80 meters. Or another 7 to 9 atmospheres of pressure. I mean that's quite a bit of pressure but you can free dive that with training. (It's around 40 meters/5 atm of pressure if your a casual diver.) You just need to make your structures strong enough to withstand that. Example. If your structure or sub is only suppose to go 200 meters, engineer it to survive an extra 100 meters. Never just do the bare minimum. That way if anything happens, it can withstand unforseen issues.

[@13minutestomidnight]

If we're talking about more space for humans to live, then that could just be solved by Simon's preliminary mention of buildings with a few bottom floors underwater and the rest of the building stretching above water. If humans started to build such housing into relatively shallow sea floors in coastal waters (say less than 50m deep) , that would provide living space without requiring the whole "living deep underwater" complexity. Cities could be modelled after places like Venice - but with basement floors that could be usable. In addition, you could probably build a connected community of small artificial floating islands to serve the same purpose (again, in relatively shallow waters not open sea though). For small, crowded countries, these coastal extensions would be good options to increase living space without having to build artificial islands or reclaim land. How big you could build such buildings is unknown though. Most likely, using the shallows in this way and advancing construction for use in water will be necessary before anyone actually builds deep underwater (if they decide it's worth it).

[@c.augustin]

There's land that was sea floor in the past (many coastal areas have those), and this is a much more efficient way to get more land (it can even be used for agriculture). Both solutions - getting land from the sea and putting buildings off-shore in shallow waters - come with their respective problems, especially in times of global warming. Both are expensive. And don't underestimate the corrosion problems salt water does pose to the buildings standing in salt water.

[@QBCPerdition]

There's no need to build in water, just build tall buildings on land. I'm not even talking about going after height records, just build normal, tall buildings in moderately sized cities. In America, urban sprawl is a real problem, instead of spreading out, if cities spread up, we could add a lot of living space without destroying more land to do so.

[@krisgonynor689]

It's safer to build in deep waters, not shallow ones, if you are building a floating city. You need to think of it as a ship at sea, that can ride up and down and over waves. In shallow coastal waters, waves are more dangerous, as is storm surge. At best, your floating city would end up in pieces onshore if a hurricane or typhoon hit. At worst, it would be on the seafloor. Floating in deep waters means the structure would rise up and down with the waves - it would need to be built in sections, connected by flexible roads and walkways. You would have to build it to stand up the strongest storms the local will get, but you'd have to do it in shallow waters, too. Not to mention tsunamis, which when in deep water may only be a few feet high, but 50 or 100 feet tall when they hit the coast. The Dutch have built many floating buildings already, they kind of know that they probably don't have much choice about it, if sea level continues to rise. So far, they've built up to maybe 5 floors tall, but they are building them to fit into there existing cities - with a large enough base, you could build a skyscraper that floats. Many deep sea drilling platforms are as tall as skyscrapers - some float freely, some are anchored to the ocean floor.

[@Kriss_L]

The vast majority of land has almost no human population density. It is astronomically cheaper to build in South Dakota than it is to build underwater.

@@Kriss_L So you are okay with inviting all of the Pacific Islanders to move to SD? Or people from the Philippines or Japan? Cubans and Haitians too? Sea level rise won't affect the US as much as a lot of places - but island nations and places like the Netherlands will need to have their population relocated. Floating cities make sense for some parts of the world. We will need them if we want working ports - we just can't keep moving port infrastructure inland and digging new channels for the giant cargo ships. A floating port city, with a floating rail and road bridge to the mainland, will be needed at most US ports. Which also happen to be major cities.

An underwater habitat has to be at the same pressure as the water IF it has openings to the water. If it's sealed, it could be at sea level pressure or whatever.

[@Warlock8ZERO]

I feel like most of these problems would be solved by being able to build something that is so strong, you wouldn't need to keep the same pressure as outside. I have no idea how much pressure the entire ocean would put on a building 100-200 meters down, guessing it's quite a lot, but materials and structural support techniques are getting better all the time so who knows. Then you would just need some elevators to the surface and for oxygen/food, and you're sorted. But tbh, there is so much land that is still uninhabited but just not used because it's not close to any towns/cities, it would be much cheaper to use this space first and improve transport/supply to cut down on delivery/commute times or just have purely remote jobs.

Surprised you didn't mention the other major issue living underwater would have: whether or not the houses would be able to withstand underwater earthquakes or not (and other nearby natural disasters like say underwater volcanic eruptions) which would more or less lead to instant death if the house gains even the smallest crack (it'd of course lose air but also there's also the chance of something similar to possibly the entire thing collapsing nearly instantly if it's deep enough by the forces of the water trying to push through said crack thus widening it...and if said crack affects the pressure inside the house by making it lower than outside the house there'd be the chance of an implosion too I guess). And even if the house's structure isn't compromised if something happens to the water filtration system and you can't escape from the house to the surface dying of thirst/likely hunger too will be a huge risk factor to consider. With that said if people were able to iron out those issues it'd be interesting to see how we'd evolve in the long run (hundreds of thousands to millions of years...granted we'll all be dead)...would our bodies adapt to allow us to not only survive the higher pressure (that's very likely, would more or less make everyone living there more fantasy dwarf like (short and stock builds) so their bodies can withstand the pressure) but depending on how much we spend time out in the water I wonder if it'd cause said humans to develop the means to live underwater IN the water as well or not (develop something like gills or our lungs/respiratory system will become stronger to allow us to store air longer like undersea mammals such as whales/dolphins/seals/etc...maybe even gain webbing/fin like appendages on top of that so we more or less become mermaids/mermen).

Exactly.

Good nuclear protection being underwater.

[@Kakkarot211]

makes you wonder about making underwater habitats at very shallow depths

[@qotsa2k4]

Just make a lake or pond at a high altitude and build a house in it. Should be slightly easier. And badass.

I've been to the year 3000, not much has changed but we live under water

I just keep discovering more Simon channels 💀

Underneath the sealab, underneath the water!

It wasn't impossible to build a city under the ocean. It was impossible to build it anywhere else.

[@SoHDrxy]

Really early 😳 nows my chance! I simp for your beard Simon!

Very cool and informative video. But I just want to know how we can have a video all about undersea living without even making a nod to Rapture.

[@traviswaldrop3793]

Was literally thinking this the other day.

Nobody said the facility had to be pressurized. With open access to the surface (sort of like the inverse of a tall building), with entry from the surface and you descend down into the structure, you won't need to pressurize anything. The only issue is with that much air displacing water, it would be difficult to keep it under water... so the goal would be to displace as little water as possible, using the heaviest thinnest and strongest material possible, while maintaining as much space as possible within.

What if we build the hull of the building strong enough to hold up to the delta pressure. Couldn’t you keep pressure inside the vessel lower than outside?

I feel like this is a surefire way to have someone capitalising on the need for air. "You havent paid your air bill"

Going to miss you on biographics, geographics and top tens 😢

The solution for the nitrogen narcosis would be to keep the primary living area at 1 atmosphere. This would require the use of a wet lock to enter and exit the living quarters but would solve the multiple issues with gasses at higher than 14.7psi. Submarines already do this.

Now i understand why BB had its meme-budget cut harder than Jimmie Saville's childrens birthday party bussiness.

[@Echo4Sierra4160]

Not many people could tolerate that... it's very claustrophobic. Also nitrogen narcosis is nitrogen saturated in the brain, it's like an underwater martini... then every 10 meters deeper than 30 meters is an additional martini.

Never heard that quote attributed to Mark Twain. It was Will Rogers I thought.

[@kevinhonomichl9999]

The pressure inside and outside have to be the same … well NO. We can build 1 atmosphere structures in modest depths (100 meters) it’s just really hard, expensive, and fatal if something goes wrong. Submarines go over 100 meters with 1 atmosphere

[@eridionkiorai]

can't wait for Krusty Krab to open in reality

[@TarriPup]

And then mermaid Simon will come and peer through those windows... xD

[@bladedicedragon]

You know, there is a game series that poses that very question Simon, I believe it is called Bioshock. And besides a little flaw of being run by a madman, it mostly worked
