two ideas for scuba diving

Liquid_breathing for those deep dives.... basically to last longer than normal gas tanks. perhaps it could double or triple the length of time underwater before we needed to exchange the liquid. Can only exchange the liquid in a special room attached to a base (much like the scanner room). unlocked after gaining access to area on the Aurora with laser cutter and scanning the system.

surface supplied air great for beginning stages.... unlimited air supply can only be used with a max range of 100m. would require special diving helmet to be made that would be attached to a small floating machine floating above the player located on the surface, that would be scanned in a safe shallows wreck.....

The first thing O_O That's a thing? Thats awesome! Really interesting link as well. That might be a solid late-game solution to the current issue between stacking piles of oxygen tanks in ones inventory and the higher capacity tanks that we had last update.

Isnt the second one basically what you do with the Pipe item?

Frankly the liquid oxygen should be required for X deep diving. I mean, that's pretty much why we use it irl iirc? To equalize pressure inside and outside the body?

I don't think it's actually a thing in the sense that we can dive with it Abyss style just yet, but given the tech in Subnautica is just a ta more advanced than ours atm, it seems reasonable to include it.

Liquid oxygen is used because of the extended dive duration at those depths. Extreme deep sea divers also breathe a mixture of oxygen and helium since nitrogen has an anesthetic effect on the human body at extreme pressures. The condition is known as nitrogen narcosis and can be dangerous and requires specialized training and equipment.

Yeah, Nitrox (oxygen increased to between 32% and 40% of the total gas volume) is used for deeper diving than regular air and Trimix (oxygen and nitrogen are partially replaced with helium) and Heliox (completely replaces the nitrogen with helium) mixes allow you to go deeper still, although the latter has other complications. For extended dives at very low depths saturation diving is used, but liquid oxygen is still in the experimental stage as far as I'm aware. They've tested it successfully on rats at 1 bar pressure and it's used on premature infants with breathing problems, but due to the complexity of the equipment needed to use it, I don't believe it's been used for diving as yet.

Would be interested to read anything to the contrary though if I'm out of date!

yeah, it's more theory than practical use right now... but it is based on the fact that as we are still in our mother's womb. we are breathing amniotic fluid.... it has also been in several movies... Like Abyss which is where I remember it from... seeing that this is a futuristic version of us, who says that we wouldn't know how to accomplish this by the time we are able to travel to distant planets?

as for the second question... similar, but.... the pipes are stationary and you have to swim to them to get the air, and no doubt doing it this way. you can take those pipes down as deep as you can go.... what I'm talking about is a machine, that floats on the surface. This machine will pump fresh air down a hose that would be attached to a helmet. essentially it will be an unlimited air supply up to depths of 50-100m. which is good enough to clean out safe shallows and some of the surrounding area of resources without having to go up for air every minute or 2. only thing you would have to do is go back to base or store your resources in a water proof locker(s). this would work well until you can get the seamoth fragments that are in the grassy plateaus for deeper exploration.... with this machine attached to you. you can go anywhere but no deeper than 50-100m and not have to worry about running out of air.
similar to this picture...

yeah... though we don't have that problem of nitrogen narcosis in the game... but if they ever do add something like that to the game. I do hope they add more ways to get around it... like using trimix or heliox.

your not out of date... I have searched into the deepest holes of the internet to see if I can find any info... so far other than tests on mice... found a video talking about it and the mouse looks like it came through the ordeal just fine.

only other tests have been on helping premature babies that haven't fully developed their lungs yet. so it's looking like it's becoming more a reality than sci-fi....

The rat from the movie abyss was actually submerged in real liquid. I forget the name of the stuff but it wasn't movie magic or anything like that. The rat was actually breathing just fine in it. I believe the director said he adopted that rat after that scene and it lived a normal life. There is well documented use of these kinds of liquids being used to treat premature infants who's under developed lungs would otherwise collapse in a normal air environment however it was found to have the same effectiveness as another procedure that was already common place so it is no longer being used.
