Thread 63979674

Why don't they harvest food from the ocean like the nautilus? Or do they?

>>63979674 (OP)
It's feasible, but not exactly practical if your main goal is to be stealthy

>>63979674 (OP)
It's hard to remain undetected when you're out hunting whales with torpedoes and using divers to harvest the remains.

just have a bow opening and harvest kelp

The open deck of a nuclear submarine is too difficult to work on.

military and civilian research subs do those weird or practical experiments. there's still quite a lot going on in the water. it's a mostly quiet field even on the civilian side (which tends to work with the military).

>>63979674 (OP)
Why would they?

Fuck I wish subs were real

>>63981378
So you're saying we are just too lazy as a society.

>>63979674 (OP)
What bullshit AI rendering is this?

>>63979674 (OP)
The limiting factor on a sub's endurance isn't provisions but the crew's sanity.

>>63981710
They are. I had one for lunch.

>>63981891
These submarine disasters are all too common these days

it's less riskey and much cheaper to let fishermen fish and buy supplies from them

It's pretty nuts in hindsight. The man had absolutely zero concept of atmospheric pressure.

The biggest limiting factor of how long a sub can remain at sea is food.

>>63983115
> The biggest limiting factor of how long a sub can remain at sea is food
Which is irrelevant if you have a friendly port and/or supply ship.
Gathering your own food is only relevant if you want to fuck off from the rest of civilization for the rest of your life.

>>63983182
Worked out well for Captain Nemo.

>>63979674 (OP)
the limiting factor for nuclear subs is crew morale

>>63983348
Trust me crew morale doesn't factor in at all when it comes to underway length

>>63981635
>kelp
too much volume per kcal. you want whales and seals and commercial divers like the other anon said

>>63983348
Even more reason to go harvesting. Imagine a nice fat tuna steak over canned slop.

>>63983115
>biggest limiting factor of how long a sub can remain at sea is food
That's a bullshit talking point from people that don't know subs. If you removed that factor, your next limiting factor would be the consumables required for atmospheric maintenance, producing water, and reactor (or diesel, if that's your thing) operations. And if you removed those factors, you'd need more parts for equipment maintenance and repairs. And if you stocked more parts, you're still headed back to port when you have your next inevitable oh-shit-mission-critical-system-failure-that-requires-depot-level-support. And if you somehow brought the depot along with you to replace the EOGs when they shit the bed, the crew's morale will eventually degrade to the point of sabotage and mutiny.
>making them spend part of their extremely limited free time gathering seaweed will likely hasten that last bit

>>63985801
I saw it in a documentary, relax.
>your next limiting factor would be the consumables required for atmospheric maintenance, producing water, and reactor
It's a fucking nuclear reactor on board. You don't need to refuel these things for decades. That takes care of all the needs for pure air and water.

Maintenance, yeah sure whatever, I'm sure most of it is quite fixable without some catastrophic or unseen problem while at sea where they'd have to rush home for.

>>63985825

You do know that recreational scuba diving is a thing, right?

>>63985825
>I'm sure

>>63979674 (OP)
No reason you couldn't trawl on the surface but getting the catch onboard while submerged would be a nightmare.
Much easier to just resupply in ports or from ships rather than filling the tiny freezers and needing to surface to trawl again every couple of days.

>>63979674 (OP)
>food from the ocean
Fish? Plankton? Sea Greens? Protein from the sea?

>>63979674 (OP)
That would breach the treaty of Tasiilaq, which secured peace by guaranteeing that humans would stop interfering with Deep One agricultural concerns, limiting fishing under the pretext of 'environmental concerns' and specifically protecting the Deep One's Kelp harvesting. It's much simpler, and cheaper, in the long run to supply subs with food grown above water than it is to risk rekindling that war OP.

>>63986518

Remember, if you have many subs for lunch, it might take you to places you don't want to go.

>>63985825

Okay.

I know exactly what I'm talking about because I saw a documentary.

>>63981710
>I wish subs were real
They are though, you just gotta look harder.

>>63979674 (OP)
Too deep. Submarines tend to stay at 500 meters underwater where the pressure is 725 psi. Just opening a hatch to take on food would flood the ship. Submarines would need to come to the shallows to get food and that's super risky.

>>63987579
At least a good answer. I just googled it and a commercial diver can go as deep as 300 m if they do saturation diving. In the movie they have a chamber that is the same pressure as outside so the water doesn't flood in. Wouldn't be hard to have a hyperbaric chamber on a ship so large.

>>63987609
>In the movie
Well there's your problem. Movies lie to you and a moon pool like that only work at shallow depths where you can afford a pressure hull inside the pressure hull. Never use a movie as proof of anything.

>>63987641
20 000 leagues under the sea is cannon.

>>63987644
200000 Leagues Under the Sea is a work of fiction. Are we talking about Real submarines or Fictional submarines?

Both.

>>63987654
I'm a sovereign citizen and you have to tell me if you're an under cover cop.

>>63987650
Fictional subs don't harvest their own food because it would make ports meaningless and destroy the necessity of any conflict.

Real subs don't fish because it's actually incredibly difficult to obtain food at 500 meters below sea level. It's just not practical
>>63987654
At least 30%. To be fair, 4chan is an anonymous board so we can't really shun the idiots until they wise up.

Not if your mission is to take vengeance upon the human race who wronged you.

>>63987814
Except now the enemy subs can fleet from you endlessly and nothing ever gets done.

>>63987820
There are no enemy subs. You invented nuclear fission but didn't tell anyone.

>>63987825
Then there's no real need for fishing either. Just raid random fishing villages and submerge before retaliation arrives. Morality? You're taking revenge on HUMANITY. Morality burned to fuel your vengeance.

>>63987849
cpt nemo is actually quite moral, at least by his own measure. he attacks military craft all the while concealing his great power that he can't justify telling the world or it will fall apart.

Imagine being a submariner and getting all of the free shrimp, king crab and lobster

Why don't we just add on a special device for filter feeding to the front of the sub?
>mouth opens and water and prey flow into chamber

>>63988088
Right?
>>63988089
I don't thinks that's economically feasible. Much simpler and cost effective to have trained divers go and collect things. It would have to be pretty shallow, tho, as another anon said.

>>63988113
Fuck your economics I want to be a whale shart

>>63985825
The reactor produces electricity, which is used for electrolysis to make oxygen. But the electrolysis equipment needs spare parts every now and then. Far worse is dealing with the carbon dioxide. That can't be easily fixed with a nuclear reactor; you have to use expendable chemical scrubbers, and once they're "full", your time underwater is very limited.

We don't have fully closed-loop regenerative life support systems yet... not even for space travel.

>>63988172
Are carbon scrubbers not reusable? I heard they have a funny smell.

>>63986518
>>63979674 (OP)

Laugh all you want, the future marine sensors may or may not be indefinitely fueled by "marine biomass". From sensors it will move towards drones or drone systems, until we have whale-sized energy harvesters charging smaller underwater combat drones, with energy delivery drones dropping batteries to contested areas.

>>63988194
>indefinitely fueled by "marine biomass"
Are you suggesting they use animals for fuel?

>>63979674 (OP)
Submariners already get the best food in the Navy

>>63983115
The biggest limiting factor is your crew getting the "underground for days" mood debuff and eventually having mental breaks or becoming ineffective workers. Modern food can be made so it doesn't spoil, and you can cram enough in storage to last literally years.
So if you need to let your crew out of the sardine can every now and then you might as well just stock up on other supplies while you wait.

>>63988203
Until the fresh stuff starts to run out.
>>63988204
I'm surprised there isn't more screening and training for people to be in such a small place for so long.

>>63988208
Only people signing up are at least a bit nuts, So screening them would counter productive.

Instead of harvesting food I'd have a Hydroponics section dedicated to growing fresh food on 1 or 2 subs at most. Not to provide 100% of the crew's food, but to act as research and development for future 100% enclosed systems ie; space colonies/ocean floor colonies, so you can get all the kinks ironed out before attempting such a huge task.

Some are but the really good ones chemically bind to CO2. Releasing the CO2 means putting it in a kiln. It's easier to mix the CO2 into water and then eject it into the sea.

>>63988202
>Are you suggesting they use animals for fuel?

While people talk about "plankton", there's different categories...phytoplankton converts light into carbs/protein/fat, but zooplankton eat the little guys...and zooplankton can be large, for example jellyfish are zooplankton.

At some point there might be a drone that sucks in jellyfish to power their anti-chinese sensors. And for all practical purposes, as this technology of converting biomass to electricity develops, who knows what happens next. Maybe the "mobik cube" meme is just a prelude to drone-related nightmares we have not yet seen.

>>63988292
I feel like that's a step backwards compare to nuclear energy. It's just doing what we always do: kill things and burn them.

>>63979674 (OP)
Submarines are autotrophs, they just need to get near enough to the surface to photosynthesize for a bit each day.

Its already a shitty job let the men eat steak n eggs instead of the same shrimp and fish everyday

why didn't over crewed Man 'O Wars in the age of sail do any fishing, back when they'd be all over and the ocean was full'O fish. Sometimes they be in a hurry but much of the time they'd be just pulling their puds. I'm thinking there would be lots of places to get fresh water but salt beef and hard tack harder to come by. If you find any source of water you could refill the whole fleet, but a small island might not have much usable food.

All the Euro age of sail nations had big sea food cultures.

>>63988089
Redundant. Open up any main or aux seawater supplied system for cleaning and knock yourself out. Plenty of sealife to be found.

If you're using monoethylamine, it has a smell reminiscent of urine. Coupled with the diesel exhaust, the overall odor is similar to pissing in a truck's exhaust pipe.

Idle hands are the devil's playthings. It would give the men something to do. Could even turn it into some friendly competition "whoever harvests the most meat by the end of the week doesn't have to eat it".

Don't need to find our own fish. Orcas have started doing it for us. First they helped us with whaling, then they sank migrant boats and rich leftist yachts, now they bring us free fish. Truly they are our greatest ally.

There's a reason sub warfare is volunteer only unless you're a nuke, and they do intensive screening. Both by actual doctors/psychologists and also existing crews. IIRC whatever sub you're first attached to as a probie out of training, you basically have to get the entire crew to sign off on you.

Did watch the film, the literal Eastwood spaghetti western music is insane and the female orca pretty much suicided. I do condemn the firsherman and the accidental orca stillbirth but the real message of the story is the male orca was fueled by self destructive vengeance and presumably dies from suffocation at the end as a result of his own actions. I'd also say the premise of the film is a bit goofy since orcas don't even mate for life, they just hit it and quit it and go back to live with their mom like 90% of 4chins users.

Probably not that many. You can’t launch missiles from under ice. I would imagine the fast attack subs are shuffled around or patrolling bottleneck waterways as needed. I would assume 5 or 6 regularly cover the arctic between the USA and Russia.

He told me his job is to wrangle wagies and oversee the nuclear reactor, which I believe makes him the engineering officer. His degree was in nuclear engineering.

The ocean is a desert with the Earth's biomass being along coastlines and where plankton congregate if the current allows it. That's the real reason sharks can detect blood from miles away. In the best case scenario is you would have subs congregating around Antartica during its summer but the Southern Ocean is dangerous and it's useless to be there.
