Scuba Breath

My perception of a pristine and peaceful scuba dive changed when I went for my first dive off the Great Barrier Reef. It looks so easy in the movies, but the breathing underwater with an oxygen mask is difficult. Don’t let those practice lessons in the swimming pool fool you! To make it easier for us, here is the Triton Oxygen Mask For Diving. It is a very convenient oxygen respirator concept that allows us to breathe under water for a long time by simply biting it. It also does not require the skill of breathing in and out while biting mouthpiece like conventional respirator.

  • Triton uses a new technology of artificial gill model.
  • It extracts oxygen under water through a filter in the form of fine threads with holes smaller than water molecules.
  • This is a technology developed by a Korean scientist that allows us to freely breathe under water for a long time.
  • Using a very small but powerful micro compressor, it compresses oxygen and stores the extracted oxygen in storage tank.
  • The micro compressor operates through micro battery.
  • The micro battery is a next-generation technology with a size 30 times smaller than current battery that can quickly charge 1,000 times faster.

Triton is a 2013 sadi product innovation studio project.

    Christopher is just a modern day version of what Robert Fulton had to put up with and his steamship. The local wags called it “Fulton’s Folly.” Close minded and incapable of embracing change even when it’s good for them.

    As an engineer this shit pisses me off,

    Making pretty pictures and doing no Maths is not ‘Designing’, designing is what I do, and there are literally scores of reasons why this is total bull.

    But it’ll get thousands of shares on Facebook anyway, because hey, pretty pictures, who gives a fuck how it works right?

    The most obvious things that spring to mind are that humans don’t breathe pure oxygen, doing so is deadly, air is 21/79% Oxygen/Nitrogen, so where does the nitrogen come from?

    Regardless of composition how do you even get enough gas to actually expand your lungs in the first place? You really think there’s that much Oxygen suspended in the water? Nope.

  • JerryH says:

    Your discussion is excellent, but it’s based on the rather simplistic description of the technology in the article which targets a mass audience. My guess is the technology separates *gases* from water and that the partial pressure balance is whatever that might be at any depth or area of the ocean. My question would be it’s ability to deliver the required volume of gases to fuel the body. Hard to imagine as described, but I certainly applaud the effort and hope development continues.

  • DeathByDrowning says:

    Hmmm, I don’t know much about the physiology of breathing air underwater, even at shallow depths. I do have several degrees in fields related to this technology, though, and have a few somewhat relevant comments. 1. Being very familiar with the field of surface science and nano-fabrication, I will say that there is not yet a known way to create pores of consistently narrow distribution to separate an Oxygen molecule from a Water molecule just by “molecular sieve” type structures. Oxygen and Water are very close in size, and in fact Oxygen is MUCH larger in the longitudinal direction and only slightly smaller than Water in the transverse direction; in other words, Oxygen needs to “allign” itself to the channel to slip through, and without any known mechanism to allign such a non-polar and small magnetic moment molecule, it seems unlikely that the filter could be efficient. Futhermore, once introduced into a channel narrow enough, the two molecules will not exhibit enough of a “hydrophobic-hydrophillic” effect to be of much use in separations. In fact, forget the breathing aspect of this, just having the technology to create such narrow and precise pore distributions would be a game changer in many chemical separations. 2) much has been stated above about relative solubility of Oxygen and Nitrogen in sea water. Although it is simple to think of “Air” as a homologous substance, it is in fact a mixture of several molecules that each have their own solubilities in water. Think of it this way, there is “water vapor” in air (or whence rain? clouds?) but that water in air is 100% soluble in seawater (duh!). So the it would only be happy serendipity if the proportional concentrations of Nitrogen and Oxygen in Seawater were exactly the same as the proportions in air: which, unfortunately, they are not. Nevertheless, the problem is that the concentration of Oxygen in Seawater is about 6mg/l. That is 0.0006 g per 1000 g of seawater (roughly). To get enough Oxygen for one breath (assuming that you have the correct makeup Nitrogen gas available to get to “Air”) requires a whopping 1 tonnes of seawater to be processed for one human breath. If you need to extract Nitrogen too, it would be about 2 tonnes for the nitrogen and that is assuming 100% efficiency! Fortunately, in this case, the math is fairly easy to just estimate: it takes about 25 liters of “air” / minute for humans at walking exertion (25C at sea level), that converts to about 5 liters of Oxygen / minute, so about 6 g / minute of Oxygen, since there is about 6 grams / tonne of Seawater, we get about 1 tonne per minute at 100% efficiency.

    The article was surprisingly detailed about the battery, but it would be one hell of a battery that could indefinitely pump 1 tonnes of seawater / minute even over a very short distance.

    I’m afraid that not only the device most likely unsafe as solely and Oxygen extractor for the physiological reasons already stated, but the technologies required are extremely advanced, so far as to be fantasy at the current state of the art. If and when they technologies are available, there will be many, many applications for them that far exceed the utility of making breathing underwater easier.

    I think the pure oxygen issue is a misunderstanding, air dissolved in the sea is roughly same proportions as normal air 80%N2, 20%02. The issue is that our warm blooded metabolism needs a substantial amount of oxygen each minute, but each cubic meter of water contains very little dissolved gas. So any artificial gill for humans would need to process a very large volume of water per minute to extract enough dissolved gas. (likely to be tens of cubic meters/minute) SO the artificial gill would need to be bigger than this and have some way to force plenty of water through it – like fish do !
    Notice that none of the ‘higher’ animals than fish that live in sea rely on gills – reptiles (turtles, sea snakes), mammals (dolphins , whales) all breathe air at the surface and use lungs as that provides the flow rate of oxygen their metabolism requires.

    Whale shark ?
    Manta ?

  • JerryH says:

    I’ve always favored the little guy with the big dream. The fact is ion channels routinely separate ions from water through our cells walls, which also pass oxygen and CO2 in and out, and were synthetically fabricated in the lab more than 30 years ago. How many ion channels can you stack on the head of a pin? A whole bunch. Skepticism is OK, but it’s confined to our knowledge of the subject. In theory there’s no need for such a device to be larger than the gills of a man sized fish. The pump? Electro-endosmosis. No moving parts. We need to dream, folks.

  • how to buy the triton scubs mask/

  • Graham says:

    You can’t buy it, it doesn’t exist, and it’s never going to exist., and I’m certainly not going to waste ny time explaining why, when you’ve ignored so many posters who’ve already explained.

    Can I interest you in a Star Trek transporter? Comes complete with sparkly effects…

  • JerryH says:

    Those who’ve posted here with reasonable arguments that this can’t possibly work, have based it on their current knowledge of the topic and the surrounding technology as they know and understand it. “Never going to exist?” Certainly not from someone who thinks that way.

  • mik says:

    Then dont you think we have to go back to the drawing board? Heck people were laughing about people flying and breathing underwater. guess what happened.

  • mik says:


    if people continue to think it will never happen it will never happen

    Man people say we cant go underwater well Jacques Cousteau helped alot

  • Graham says:

    Flying was always going to be possible – birds have been demonstrating that it is possible.
    The amount of dissolved oxygen present in water is so low that to extract enough to keep a human alive, you’d need to process so much water that the device would also make a very fine propulsion unit.
    This is not, and does not actually claim to be a viable product; it is nothing more than a student’s design exercise. The student assumes some hypothetical technology and “designs” a pretty package and creates some pictures to market it.
    Personally, I figure he should get full marks, based on how many scientifically illiterates are queuing up to buy one or to tell us that the realists lack vision.
    Some things are difficult but might one day be possible, like flying, putting humans on Mars or curing cancers. This is not one of them.

    • Art says:

      Wrong! This is possible too. 150 years ago the idea of putting a man on the moon, tvs, iphones, drones, robots, etc. was unheard. You need vision my friend. Vision.

  • JerryH says:

    Birds fly, fish swim. Both are possible, but only to those with enough imagination to make it happen. The rest, the doubters, are only along for the ride when the innovators have finished their job.

  • mik says:

    exactly naysayers are there all the time

  • Marat says:

    Please tell me the price of it. I am very interested in this product and would like to become your distributor in Russia and CIS region.

    Thank you
    Looking forward to hearing from you soon.


  • Graham says:

    Marat, this is a comments section, not an email service, and an imaginary product of a student’s mind, not a physical possibility, for reasons that have been explained many times above.

    Oh what the heck, sure, I can supply 1200 units per 20ft shipping container, ex Seoul, for US$32,643 per unit, payment in advance. If you’ve got $40 million lying about, I’ll happily pretend this thing can exist and spend your cash “developing” it for the market.

    I weep for humanity.

  • mik says:

    you weep for humanity for trying to create something like that? people said or one guy said people wont want color tv well guess who was WRONG

  • Graham says:

    No, I weep for humanity because this is no more than a student design (NOT engineering!) project, packaging clearly fictitious, non existent technology to demonstrate how a “design” student would package and market a new technology, yet so many people are unable to grasp that it does not exist, and that it simply cannot exist in the form described for a variety of reasons explained over and over again, not the least of which is that if the device actually processed enough seawater to extract sufficient oxygen for a human being, it would make a very fine jet propulsion unit and just about tear your head off.

    – The batteries don’t exist, though they conceivably might, one day.
    – The micro compressor doesn’t exist and the fluid dynamics principles preventing it from existing are well understood.
    – The filter, with holes smaller than water molecules, to let the oxygen through, is fundamentally flawed, since O2 molecules are LARGER than H2O molecules.
    – The storage tank doesn’t exist, but why would you try to make it so small anyway?
    – The designer has demonstrated his complete ignorance of diving physiology.
    – But most of all, it’s a student exercise, a fiction, written as if it were real, to demonstrate “design” (eg: product packaging and marketing skills), not engineering reality.

  • mik says:

    so why not instead of being the naysayer say why it wont work and offer something that can be used? Okay its flawed but maybe they can use the design on a bond film??

    plus teach them engineering skils

  • Gudrun says:

    If you want to get much from this post then you have to apply these methods to your won webpage.


    Is this underwater breathing technology been approved by a diving authority for use by divers? Please tell me the price of it & how to buy the triton scubs mask.


  • Graham says:

    It’s a “design” student’s “concept” of something that doesn’t actually exist. It does not exist. It cannot exist. It’s NOT POSSIBLE.

  • Mordj says:

    Hi Ron,

    You got it mate : We have hyddrogen here. So the device would need serious modification to extract 80% to 93% hydrogen and 20% to 7% O2 to have a viable gas composition to breath. This of course make things quite dangerous as you are carrying a battery.

    The other thing regarding design I see not fitting here is the shape : I would integrate this device as a stab and uses the stab as a filter just like with a CCR rebreather. That way you carry a bigger battery, you have a way bigger capacity of volume extraction and stronger compressor fitting the depth you need to attain (more depth = more compressing).

  • CommenterCock says:


    So he found a way to take oxygen from the water or thinks so. So now he has to take all your input and find a new way.

    It’s people like you who shut down the world of possibilities.

  • Shahin says:

    I have a question.doese this new technology have depth limitation?

  • Wilder says:

    Has anyone considered the thought that this thing might actually be splitting the water molecules rather than extracting the few O2 molecules floating around in the water.
    I don’t understand this type of nanotech so I don’t know if this is possible. Assuming it is though we would have the ‘reaction’ 2 H2O -> O2 + 2 H2.
    So you would have a 1:2 proportion of oxygen and hydrogen that you are breathing which is similar to the approximately 1:3 proportion of oxygen and nitrogen in the air.

    The nitrogen isn’t used in our body, its just a space filler and can be replaced with any gas that doesn’t affect us. In this case hydrogen. The proportions are also close enough that we won’t get oxygen poisoning.
    So do I think that this idea has some merit, although the critics are right about the battery and compressor problems. But they are relatively minor and we are close to the technology needed.

    My point is that you are seeing this in the wrong way. The maths works out, now we just need the tech.

  • Wilder says:

    Im 15 by the way. Seriously, how has no one even considered this yet?

    • paul curran says:

      This has been considered for a very long time. However the technology does not yet exist that enables such devices.
