According to my cousin, who used to work on oil rigs in the North Sea, you need a certain disposition to work as a deep sea diver. Based on her experience, that disposition is "completely and utterly fucking mental".
Saturation diving is horrendously dangerous and as well as requiring immense skill each dive eats away at your health and longevity. ADS diving is a lot safer but rare
Actually, it paid really well, but it is a young person's game since repeated deep saturation diving apparently causes the bone marrow to compress. Or at least that is what I was led to believe but left the field when Desert Storm happened as I was recalled to the military. Still, it takes a different mentality to do the job.
Good one Dave. And I bet that's a real story too. My sister is an astronaut and president of the world and she says working on oil rigs in the North Sea is a lot like playing donkey kong while being sexually harassed by Elund Munsk.
The problem that we've encountered with liquid atmosphere breathing for diving is the fact that the liquid is very viscous. It doesn't move through the lungs enough to remove the CO2. So it works... kind of... but the problem is getting the C02 out of the lungs. They kept mice alive submerges in one of those liquids for several minutes, but they all quickly died due to carbon dioxide poisoning. They also did some human trials on near death premature infants which showed some promise in 1989, where they used a fluid to inflate the infant's lungs to start them breathing. The premature babies all still died, but showed physiological improvement, so they're looking at doing further research. Premature babies often have a really hard time breathing and they're looking at using it as a way to re-create the liquid breathing from inside the womb with it.
Don't forget about rectal breathing, proven by the infamous experiment of pigs sitting in a tub of oxygenated perfluorohydrocarbons, inhaling the oxygen through their but. It's been proven in many species of animals and would work in humans too.
Even more amazing is the suits were able to house the enormous balls of those who agreed to be put into them and dropped into the abyss... you arent putting me in that contraption and sending me to the depths... not happening. My hats off to those folks.
I think it's honestly a certain mindset that you need for diving, less so than chutzpah. When I first started diving the hurdle was overcoming that instinct to not inhale when you're submerged, you have to basically de-wire the fear and self protection responses. Bravery doesn't work as a substitute, you have to be built different, or train yourself for a whole new way of functioning. I will say that it is nice not to get crippling thalassophobia when playing games like subnautica; ironically it was the irritation of the incredibly small oxygen limit not letting me explore and get lost in the depths even more that miffed me. I felt shackled to the surface, or a submarine, and I just wanted to swim off like a fish and get lost in the beauty of the deep.

To add a little context: the lacking hand dexterity is the single biggest reason you don't see more of these operating (and likely never will), at least in commercial diving. ROV's have made major advances, alongside robotics in general, such that they can now perform most any job that a person in an ADS could (for much cheaper, and without risking a life). Meanwhile, both an ROV and an ADS diver will be severely hampered if not useless in zero-visibility conditions-which are the norm in many areas. Divers have eyeballs on the ends of their fingers-we are trained and accustomed to working blind. You can't really do that through a lobster-claw, though.
Give it time, we're making a lot of advancements in mechanical human-hand analogues and haptic feedback. I have little doubt that you will one day be able to put on a pair of gloves connected to a control system, and control a pair of hands with near-real feedback on touch provided by sensors on the working hands, and haptic feedback in the gloves. We already have working models, so comercial adoption is just a matter of the timing being right when someone presents a system, or industries go hunting.
Multi spectra or synthetic imaging technology to see through the "haze". The sensors are probably in prototype or the government has perfected it and wishes to keep on the very close hand to vest. I could see some landmarks to calibrate the sensors on the sea bottom equipment to be serviced i.e. up down left right.
@@kauske It's not impossible, but there will be many challenges. It's not _just_ the dexterity and feedback to the hands, it's also spatially "mapping" your surroundings in your head, by feel alone. I imagine it's similar to how the blind get around and avoid losing stuff in their house (just not as gracefully, and underwater). In dive school, one of our tasks was to go to the bottom of the tank, blinded, and assemble four pipes and elbows into a rectangle. They were varying lengths such that things would only go together one way, and you only had a few minutes. You'd be surprised how few of us pulled it off on the first try! The winning strategy was to first measure the pipe lengths against your forearm, to sort them by length. Then you have to carefully 'index' each pipe to a different body part..."long: left knee, short: right knee" and so on. If you absent-mindedly set something down a couple feet away, you'd lose minutes searching for it (and this was in a small, flat training tank). This was a very trivial exercise compared to what we do on real job sites, but it would take a lot of clever technology to replicate human proprioception (your sense of your own body's position in space). I'll be interested to see how things progress.

Yep, so about we all take a moment and say a prayer for Edwin Arthur Coward, Roy Lucas, Bjørn Giæver Bergersen, Truls Hellevik & William Crammon. Good men all- who died trying to take care of their families
Wow. This was an interesting and impressively comprehensive history of the ADS... Great vid! (Though, I suppose they will be replaced by remote controlled submersibles, with more advanced robotics (and maybe even VR?), lower cost and risk I can't see why to continue using people on the spot rather than at the surface. These are still very cool.)
Nice. As a diving ecologist I am very much aware of the 30m practical limitation to air/nitrox SCUBA diving. Lots going on down there that it's not possible to get at without going 'more complicated' - accelerated decompression, trimix/rebreathers, saturation diving and atmospheric diving suits. So I've always been interested in AD suits and knew about the Newt suit and earlier JIM suit . It's pretty much true that at each stage of complexity increase beyond air-based SCUBA cost increases hugely and consequences of a SNAFU increase in severity. Explains why such techniques have had a much stronger showing in oil/gas exploration, salvage and engineering than in the biological sciences: they get used where the money is. It's also true that ROVs and drop-down video can do biological surveying and a certain amount of sampling at lower cost than saturation diving or AD suits. BUT these techniques can't directly replicate the input an expert person can have in things like accurate in-situ identification of species where touch and even taste come onto play. Nor can ROVs/ video interact with the environment in which species are found so habitats like sediment veneers on rocky and stony reefs go unrecognised and reported as 'sediment'. Which is something completely different. I hope that in the future it will be possible to go deeper at a 'reasonable' cost and still interact with biotopes and so increase our (still sketchy) knowledge.
@@WallStreet06 I get paid to dive and record species and their interactions on the sites I get directed to. This is usually to find out if habitats and species are changing, perhaps in response to human activities. I work anywhere around the UK - in temperate waters we don't have coral reefs, but we do have coral species and a lot of other things. Temperate waters are far more nutrient rich than tropical ones where coral reefs are found, but the nutrients tend to derive from river runoff, which means the vis isn't as good.
I'm still amused at the fact that Al is a HIGHLY reactive metal akin to Sodium and Potassium, being from the same area on the periodic table. The thing that makes it so that we can wrap our hot dogs in it is an oxide layer that forms near instantly on the surface that's essentially non-reactive.
It's a whole lot simpler and cheaper, in operational terms, than saturation diving! That runs well into six figures _per day_ to keep a diving support vessel on station. It takes a crew of ~50 to support just a handful of divers, and those divers are making 'depth pay' the entire time they're under pressure, wet or not, asleep or awake. Big bucks (if you're good enough, and when you can get it).
Because most of your body is incompressible liquid or solid the only patrs affected by pressure are the air spaces. Because you are breathing gas at the pressure of the water around you these too are unaffected. So apart from clearing your ears on the way down being at depth feels absolutely no different to being at the surface.
You're supposed to clear often or you will blow your eardrums out! We can't really feel pressure, but the largest changes are within the first 10 feet. Add 1 atmosphere of pressure every 33 feet. 200% pressure change going from 1 ATMA to 2ATMA vs going from 1700 feet to 1733 feets only a 101% difference.
@@insearchoftheperfectwatch934 not with scuba gear. Your regulator will give you gas at just above the water pressure around you so breathing stays easy.
@ I wasn’t really trying to focus on the definition of psi just the crazy amount of weight but fair is fair I definitely didn’t need to type the last bit of just one inch of ur body when I already said psi 👍
5:30 Nitrox is adding more oxygen to the breathing gas, which increases bottom time but decreases the maximum depth you can use it at for fear of oxygen toxicity. The deepest you can use nitrox is around 90 ft
Fun Fact: Whilst the JAM, SAM and WASP suits were made of glass fibre, they made a prototype version of the SAM suit out of carbon fibre for the U.S. Navy because they thought it'd allow for super-deep espionage dives and the like. The Oceangate debacle will tell you how well that went (in an unmanned hyperbaric test, it failed at less than half the operational depth of its glass fibre counterpart).
You can actually breathe ordinary air way beyond the recreational limit of 40 metres/130ft. The 'safe' limit is 66m, although beyond 86m there is significant risk from oxygen becoming toxic to the nervous system, leading to convulsions and death. Also, depth on its own does not give you decompression sickness. The clue is in the name. As you later say it's the coming back up where you have to be careful. Nitrogen narcosis is not a problem just below 40m. It's an individual thing and some people get 'narked' at as little as 25m. '500 weight' (9:21) is actually 5 hundredweight, ie 5cwt or 560lb. I guess they don't teach Imperial measures in school nowadays. The pressure issues with space suits are minor by comparison. They only have to deal with up to 1Bar of pressure change. The temperature range is the problem. For the first 'modern' ADS (15:35) I assume you're referring to Neufeldt Und Kuhnke. FYI it's pronounced 'Noy-felt and Koon-ker'. Cast magnesium and sea water; what could go wrong? As you say, dexterity is still a big issue and the answer has to be in more complex robotic whole-hand systems. But there's the rub for the ADS. It's cheaper to run a robotic hand remotely from the surface. Current advances in ROV tech make the ADS pretty redundant.
Simon, the Navy Personal photo shown at 4:58 is incorrect. While called SCUBA, it's for firefighting on a ship to let them have their own air supply. They used to use oxygen candles directly connected to a hose for them to use, but they tend to blow up when wet.
I feel that an opportunity was missed at the 5:14 mark, a clip from The Abyss movie with the SEALs ("... and a partridge in a pear tree!") would have fit the video and Simon's brand (especially the BB portion!). 🤓
25 years ago I saw a tv program about the manufacture of a state of the art hard suit and the main body was made from a single giant piece of aluminum that was put into a giant hydraulic press where it was squashed down to about half the starting size in order to make the aluminum denser. It was then machined.
I remember when the first Jim Suit hit the news. As for manual dexterity, I would go with waldos where robotic hands were operated remotely by the diver.
Upside to growing up near offshore oilfields: one middle school job fair included some folks from Oceaneering and what I'm pretty sure was a Wasp suit, which I and probably a hundred classmates got to try on, play with, and probably annoy the hell out of the guys responsible for it. I got such a kick out of it as I'd gotten my open water scuba certification a couple months prior.
27:07 Simple; look to the new revolution in prosthetic limbs (particularly hands) as well as video game controller periferals, and then combine the two.
I'm a subsea engineer. We make those 1 atmosphere systems and use them in the gulf of Mexico. They are claustrophobic and it's definitely not for everyone. They are better than that white one you showed at the start but even so, they have limitations. You're better off using an ROV. They are unmanned and can just do more. Apart from shallow water, there's very little reason to put a human in the water.
Oceaneering used to be based in Alton Hants if I remember correctly, I'm 60 now and grew up thereand remember seeing their signs about and also I think they had a small fleet of the Outspan orange 🍊 cars based on minis.
It seems like one might be able to view it as clothes instead of being inside of a compartment. Never tried, and since I have claustrophobia as well, don't see any reason to.
What I have never understood about the lobster claw approach is that we can make fairly dexterous robotic hands with strong grip strength. Yet nobody seems to have simply made gloves with feedback and combined the technologies. Maybe it would not work, but it seems odd nobody has at least tried it.
About 5:30 you’ve clearly put a picture of folk checking fire crew breathing apparatus on an aircraft carrier, there’s bloody planes in the background, and no dive boat is that clean!
Breathing oxygenated fluorocarbon compounds or even saline solution saturated with oxygen for deep dives will probably never happen. The problem is it's like breathing unset jello. Because of the viscosity, you will get around 4 breaths a minute. The faster you breath the more oxygen to compensate for the added work. It quickly becomes a vicious cycle. The work around is to stop breathing. If a liquid had enough oxygen that you only needed to breath once every minute or so. But you run up against supersaturation issues. You can only dissolve a finite amount of gas into the liquid.
Check out the other pressure suit, the AX-2. It was going to be the latest and greatest in NASA Space Apparel...(un)fortunately, it was never adopted. The suit moved quite well, but it didn't move like a human...natural reflexes in emergency would cause the joints of the suit to lock-up. While it would have solved many space-related issues (radiation and micro-meteor protection), the lack of proper mobility doomed the project.
If it had robotic arms and legs it could eliminate the joint problems. This would require plenty of electric power but that should be feasible, especially with a tether. Have sensors on a bodysuit to operate it.
Simple solution to the claw problem is to have electric actuators that controlled by gloves over the hands. Basically a Nintendo power glove that controls a diving suit.
Seen how those JIM diving suits are made. A massive billet is compressed in a huge hydraulic press, kind of cold forged, then it's milled to shape. Process is very very time and resource intensive. So much material is wasted in the process.
In 1459 Hans Tallhoffer published a manual/fight bookthat depicted a diving suit. Historians believe they did exist & probably did from a bit earlier in history; although they are not sure what they were used for. Air would be pumped down to the diving suit through tubed from air bellows.
the bad guy hench man in the 80s movie inner space had a diving suit that was in the human body shrunk down, what would the pressures be like at microscopic scale in the human body ? some research for the found out team . thank me later
One minute.... You mention the Bond movie "For your eyes only" a number of times, but no mention of Graham Hawks? The marine engineer that designed the pressure suit used in the movie, as well as the one-man OSEL Mantis submarine (that he pilots in the movie). Hawks is allso a ex-husband to Sylvia Earl.
I wonder if we could combine a modern exoskelleton to such a suit to make it able to go way deeper then currently possible. But I guess it is more easy to just use remote controled androids.
6:45 - Sorry, but that is not the most gruesome death imaginable. Not by a long shot. In fact, its so quick you don't know it happened. However, 'The Squeeze' ( 3:28 ) ...now THAT was the worst way to die (in diving). Your body (often) wasn't forced into the helmet immediately. Oh no. You felt the pressure increasing, the suit tightening, constricting. As in continues, slowly snapping your arms, legs etc. As it starts to extrude you into the helmet and air pipe (like slowly squeezing a tube of tooth paste). This might be why, today, we make sure when something fails (in diving) its graciously fast :-)
We have advanced for people without hands so why not have robot hands & fingers the diver can operate remotely at the end of the suits arm? Sensitivity might be a differently but I'm sure there's sensors for that. Of course its one more place to leak but the arms can be a cap connected to the robotic hand and might be easier to seal since gloves would make your hands freeze into uselessness.
Anyone : Why don't submariners as well as users of this kind of suits use partial pressure just like airliners? If going to 1000 feet, pressurize the vehicle to 500 feet, so that the hull is handling just 500 feet between the inside and outside ... ??? Submarines have plenty of time to decompress for eventual equalization to atmospheric pressure, and "atmospheric" diving enclosures should be able to keep pressure in as well as keeping it out, so decompression should be as simple as a pinhole leak once the suit is on the deck of the support vessel. So WHY not have it done that way?
So did anyone get scared at depth and drop a deuce in their suit? And how did that go down I wonder ? The old treacle breeches always guarantees a bad time....
Technical diver here: I was fully prepared for you to butcher your overview of gasses and decompression, but you did a pretty good job. Not all of the underwater/dive support photos directly corresponded to what you discussed, but it wasn't half bad. Well done! 🐟🐠🦑🐙🦈🐋🪸🐡
I think the suits are obsolete as we have submersible robots that will handle the work down there with the operator safe on the surface using remote controls.
Aaaactually, it would be considered a submersible as it would need another vessel to transport it to and from the location of the dive. Submarines are able to self-transport. That's the technical distinction I just learned listen to the Swindled podcast. So I know a useless thing now and must share at every opportunity.🤓

Does anyone else notice that a lot of fictional robots, mechasa, cyborgs, and exoskeletons look like iterations of atmospheric diving suits.
You Brits make aluminum sound so Noble and not just a thing I wrap my hot dogs in.
Aluminium. :)
I'm sure that it's the entirety of Europe
I'm still amused at the fact that Al is a HIGHLY reactive metal akin to Sodium and Potassium, being from the same area on the periodic table. The thing that makes it so that we can wrap our hot dogs in it is an oxide layer that forms near instantly on the surface that's essentially non-reactive.
@AsmodeusMictian AL
@28:00 ...wait, what!?! - what is the maximum 'giant sea monster' size that can successfully be fought off using current ADS technology?
What a fantastically complicated and expensive way to avoid the bends. Great episode
It's a whole lot simpler and cheaper, in operational terms, than saturation diving! That runs well into six figures _per day_ to keep a diving support vessel on station. It takes a crew of ~50 to support just a handful of divers, and those divers are making 'depth pay' the entire time they're under pressure, wet or not, asleep or awake. Big bucks (if you're good enough, and when you can get it).
Even 20ft down your ears pop and you can feel the pressue so anything beyond that is unimaginable.
It's really hard to inhale.
I've been down to 140 feet, once you equalize it hardly feels different than at 20 feet.
Because most of your body is incompressible liquid or solid the only patrs affected by pressure are the air spaces. Because you are breathing gas at the pressure of the water around you these too are unaffected. So apart from clearing your ears on the way down being at depth feels absolutely no different to being at the surface.
You're supposed to clear often or you will blow your eardrums out! We can't really feel pressure, but the largest changes are within the first 10 feet. Add 1 atmosphere of pressure every 33 feet. 200% pressure change going from 1 ATMA to 2ATMA vs going from 1700 feet to 1733 feets only a 101% difference.
@@insearchoftheperfectwatch934 not with scuba gear. Your regulator will give you gas at just above the water pressure around you so breathing stays easy.
No closed captions,important and needed for some people.Now I will never know what’s about.
Should’ve mentioned that at that 650meters depth that’s about 920-945psi absolutely insane pressures and that’s just on one inch of your body!
If you're watching this, you know what psi means
@ I wasn’t really trying to focus on the definition of psi just the crazy amount of weight but fair is fair I definitely didn’t need to type the last bit of just one inch of ur body when I already said psi 👍
is that a flex on your wrist? magnificent!
5:30 Nitrox is adding more oxygen to the breathing gas, which increases bottom time but decreases the maximum depth you can use it at for fear of oxygen toxicity. The deepest you can use nitrox is around 90 ft
26:10 "HOLY SHIT....that's sooo DEEP!"
... That's what SHE said!
LOL.... Had to!
Fun Fact: Whilst the JAM, SAM and WASP suits were made of glass fibre, they made a prototype version of the SAM suit out of carbon fibre for the U.S. Navy because they thought it'd allow for super-deep espionage dives and the like. The Oceangate debacle will tell you how well that went (in an unmanned hyperbaric test, it failed at less than half the operational depth of its glass fibre counterpart).
You can actually breathe ordinary air way beyond the recreational limit of 40 metres/130ft. The 'safe' limit is 66m, although beyond 86m there is significant risk from oxygen becoming toxic to the nervous system, leading to convulsions and death. Also, depth on its own does not give you decompression sickness. The clue is in the name. As you later say it's the coming back up where you have to be careful.
Nitrogen narcosis is not a problem just below 40m. It's an individual thing and some people get 'narked' at as little as 25m.
'500 weight' (9:21) is actually 5 hundredweight, ie 5cwt or 560lb. I guess they don't teach Imperial measures in school nowadays.
The pressure issues with space suits are minor by comparison. They only have to deal with up to 1Bar of pressure change. The temperature range is the problem.
For the first 'modern' ADS (15:35) I assume you're referring to Neufeldt Und Kuhnke. FYI it's pronounced 'Noy-felt and Koon-ker'.
Cast magnesium and sea water; what could go wrong?
As you say, dexterity is still a big issue and the answer has to be in more complex robotic whole-hand systems. But there's the rub for the ADS. It's cheaper to run a robotic hand remotely from the surface. Current advances in ROV tech make the ADS pretty redundant.
Simon, the Navy Personal photo shown at 4:58 is incorrect. While called SCUBA, it's for firefighting on a ship to let them have their own air supply. They used to use oxygen candles directly connected to a hose for them to use, but they tend to blow up when wet.
SCBA, aka Scott Paks, not SCUBA
@@rscott9474 Gotta love autocorrect. I was certified to use them but that was around 9/11
Yea that’s def firefighting gear.
Falling out of a plane, skydiving acci😂dentally is awesome... This is for truly wild starfishes
I feel that an opportunity was missed at the 5:14 mark, a clip from The Abyss movie with the SEALs ("... and a partridge in a pear tree!") would have fit the video and Simon's brand (especially the BB portion!). 🤓
We love inverse space suits, but a video or videos on the history of high altitude flightsuits and spacesuits
Great video
25 years ago I saw a tv program about the manufacture of a state of the art hard suit and the main body was made from a single giant piece of aluminum that was put into a giant hydraulic press where it was squashed down to about half the starting size in order to make the aluminum denser. It was then machined.
I remember when the first Jim Suit hit the news. As for manual dexterity, I would go with waldos where robotic hands were operated remotely by the diver.
0:25
Should have mentioned the one used in the film "Inner Space". Much more interesting.
Came here to say this. As soon a i started watching this, an image of the baddie in one of these suits. I had forgotten about it for years.
Upside to growing up near offshore oilfields: one middle school job fair included some folks from Oceaneering and what I'm pretty sure was a Wasp suit, which I and probably a hundred classmates got to try on, play with, and probably annoy the hell out of the guys responsible for it. I got such a kick out of it as I'd gotten my open water scuba certification a couple months prior.
You aren’t a diver, are you? 😉 - its noticeable. But the video‘s quite enjoyable and entertaining, thumbs up for it 🙂👍
You added a next step in my diving career. 😁
27:07
Simple; look to the new revolution in prosthetic limbs (particularly hands) as well as video game controller periferals, and then combine the two.
Then go view the Titanic from a carbon fibre sub
Wow. Such a coincidence that the trailer for the movie "Last Breath" came out today~~
Weird, I watched that movie years ago. Anyway, it's absolutely _excellent_ and I cannot recommend enough.
I'm a subsea engineer. We make those 1 atmosphere systems and use them in the gulf of Mexico. They are claustrophobic and it's definitely not for everyone. They are better than that white one you showed at the start but even so, they have limitations. You're better off using an ROV. They are unmanned and can just do more. Apart from shallow water, there's very little reason to put a human in the water.
Its crazy to think they were making things like that so long ago
What I learned from this video
I wanna play bioshock again 😅
lol…”Holy sh*t that’s deep!” Well said Sir, well said!
Oceaneering used to be based in Alton Hants if I remember correctly, I'm 60 now and grew up thereand remember seeing their signs about and also I think they had a small fleet of the Outspan orange 🍊 cars based on minis.
15:52 What is a “ flonge”?😂
Cool Topic, Thank You!
3:56 🎶 _Tiiiny bubbles...._ 🎶
"Squeezing the fleshy remains up into the helmet. And air hose..." 😮
I get claustrophobia just watching this. :)
It seems like one might be able to view it as clothes instead of being inside of a compartment. Never tried, and since I have claustrophobia as well, don't see any reason to.
Great video!
26:03 These guys are experts at laying the pipe.
What I have never understood about the lobster claw approach is that we can make fairly dexterous robotic hands with strong grip strength. Yet nobody seems to have simply made gloves with feedback and combined the technologies. Maybe it would not work, but it seems odd nobody has at least tried it.
high pitch voice, which is usual with heliox, as actually beneficial for comms
About 5:30 you’ve clearly put a picture of folk checking fire crew breathing apparatus on an aircraft carrier, there’s bloody planes in the background, and no dive boat is that clean!
But what if we need to reach a space gun 5,000 meters beneath the ocean? It might be the only hope for humanity.
Is this a reference to a movie/ video game/book? I'm curious
@RextheDragon881 Soma
Space guns are rarely found that deep.
You're probably an Android at that point 😉
@@robertdean6084 when I think space gun... I think space
Breathing oxygenated fluorocarbon compounds or even saline solution saturated with oxygen for deep dives will probably never happen. The problem is it's like breathing unset jello. Because of the viscosity, you will get around 4 breaths a minute. The faster you breath the more oxygen to compensate for the added work. It quickly becomes a vicious cycle. The work around is to stop breathing. If a liquid had enough oxygen that you only needed to breath once every minute or so. But you run up against supersaturation issues. You can only dissolve a finite amount of gas into the liquid.
Check out the other pressure suit, the AX-2.
It was going to be the latest and greatest in NASA Space Apparel...(un)fortunately, it was never adopted.
The suit moved quite well, but it didn't move like a human...natural reflexes in emergency would cause the joints of the suit to lock-up.
While it would have solved many space-related issues (radiation and micro-meteor protection), the lack of proper mobility doomed the project.
The deep Ocean is more danger than enter the space on the IS Space Station😂😂😂
Those initial diving suits looked like villains in some 1950s B movies
If it had robotic arms and legs it could eliminate the joint problems. This would require plenty of electric power but that should be feasible, especially with a tether. Have sensors on a bodysuit to operate it.
Pronounced 'Loch' correctly. 👍🏻 20:54

No.
Considering disliking the video given your attitude.
In For Your Eyes Only Bond remarks in a Greek warehouse “JIM diving equipment. For salvage work in depths over 400 feet.”
The Carmagnolle suit looks like it came from a steampunk world.
Why the long pause on the aircraft hangar deck with air tanks for firefighters?
Simple solution to the claw problem is to have electric actuators that controlled by gloves over the hands. Basically a Nintendo power glove that controls a diving suit.
Yeah I'm sure with the billions they dumped in this they never thought of such a "simple" solution.
@mikerogers7502 If they did, why not make it then?
18:30 "Panzertasche" would literally translate to armor bag. Machine translation at it again
Seen how those JIM diving suits are made. A massive billet is compressed in a huge hydraulic press, kind of cold forged, then it's milled to shape. Process is very very time and resource intensive. So much material is wasted in the process.
Some of these diving suits make me want to say, "klaatu barada nikto."
Put the ad at the end of the video
Just an FYI, Phil Nuytten's last name is pronounced like Newton. Hence the alliterative name 'Nuyt Suit'.
There's been a lot of repeating videos lately, the byford dolphin accident video covered most of this material and other videos have covered the rest.
~Real Engineering has entered the chat~
🤨
"... Proceed."
Incredible and replaced by ROV's. The Navy spent millions developing one for submarine rescue only to replace it with an ROV
It’s good job ocean gate didn’t go down this route. They would have crumbled at about 15 feet.
Please enable subtitles
What makes this INSANE? Insane is a human condition!
In 1459 Hans Tallhoffer published a manual/fight bookthat depicted a diving suit. Historians believe they did exist & probably did from a bit earlier in history; although they are not sure what they were used for.
Air would be pumped down to the diving suit through tubed from air bellows.
the bad guy hench man in the 80s movie inner space had a diving suit that was in the human body shrunk down, what would the pressures be like at microscopic scale in the human body ? some research for the found out team . thank me later
Like number 832 here!
One minute.... You mention the Bond movie "For your eyes only" a number of times, but no mention of Graham Hawks? The marine engineer that designed the pressure suit used in the movie, as well as the one-man OSEL Mantis submarine (that he
pilots in the movie). Hawks is allso a ex-husband to Sylvia Earl.
I wonder if we could combine a modern exoskelleton to such a suit to make it able to go way deeper then currently possible.
But I guess it is more easy to just use remote controled androids.
Biblically accurate diving suit
Helium muscle tremors have the same symptoms as my epilepsy..
Diving suits yeah. I mean there's always something you haven't covered, this will work
6:45 - Sorry, but that is not the most gruesome death imaginable. Not by a long shot. In fact, its so quick you don't know it happened.
However, 'The Squeeze' ( 3:28 ) ...now THAT was the worst way to die (in diving). Your body (often) wasn't forced into the helmet immediately. Oh no. You felt the pressure increasing, the suit tightening, constricting. As in continues, slowly snapping your arms, legs etc. As it starts to extrude you into the helmet and air pipe (like slowly squeezing a tube of tooth paste). This might be why, today, we make sure when something fails (in diving) its graciously fast :-)
Omfg absolute nightmare fuel
We have advanced for people without hands so why not have robot hands & fingers the diver can operate remotely at the end of the suits arm? Sensitivity might be a differently but I'm sure there's sensors for that. Of course its one more place to leak but the arms can be a cap connected to the robotic hand and might be easier to seal since gloves would make your hands freeze into uselessness.
made for earth oceans yet they can work as space suits for other planets too
Anyone : Why don't submariners as well as users of this kind of suits use partial pressure just like airliners? If going to 1000 feet, pressurize the vehicle to 500 feet, so that the hull is handling just 500 feet between the inside and outside ... ??? Submarines have plenty of time to decompress for eventual equalization to atmospheric pressure, and "atmospheric" diving enclosures should be able to keep pressure in as well as keeping it out, so decompression should be as simple as a pinhole leak once the suit is on the deck of the support vessel.
So WHY not have it done that way?
We’re going to need to do more than just evolve gills if we’re going to be able to dive down to depths exceeding 600 meters, just saying.
Please turn the music down. It makes it really hard to concentrate
So did anyone get scared at depth and drop a deuce in their suit? And how did that go down I wonder ?
The old treacle breeches always guarantees a bad time....
Technical diver here:
I was fully prepared for you to butcher your overview of gasses and decompression, but you did a pretty good job. Not all of the underwater/dive support photos directly corresponded to what you discussed, but it wasn't half bad. Well done!
🐟🐠🦑🐙🦈🐋🪸🐡
I think the suits are obsolete as we have submersible robots that will handle the work down there with the operator safe on the surface using remote controls.
Theirs always something wrong requiring the use of a god created human hand especially when time is important and fabrication is to long
My Kid calls Simon "Mr. UA-cam" because he's on every channel.
Can that suit carry a man to the titanic
Atmosphric diving suit = microsubmarine
Aaaactually, it would be considered a submersible as it would need another vessel to transport it to and from the location of the dive. Submarines are able to self-transport. That's the technical distinction I just learned listen to the Swindled podcast. So I know a useless thing now and must share at every opportunity.🤓
