And I bet it just stops, too, in contrast to tanks where you get some indication by sucking harder and harder.
Probably supply enough oxygen for micro people.
I expect any day you will be able to order from Amazon an implant just under the skin of your palm that will be a complete cell phone with high speed internet access plus it can monitor all your body functions including heart, respiration and temperature, sort of a built in Onstar.
Think of Total Rekall, the new one, the players had these in the palms of their hands.
And i bet Obama wants to give these out by the millions....and guess what that will mean....
I hope they don’t accidently take pictures and send selfies while they are in the restroom with it implanted in their hand.
Although how they plan to play Angry Birds in their palms, I don’t know.
Only in SF FRiend, only in SF will they allow hand to hand communication.
Unless there is something that does the mixing between the oxygen storage and the mouthpiece.
. . . or unless there is more nitrogen than oxygen dissolved in the water, and extracted with the oxygen . . .
“Give me a hand” would have a whole new meaning
What if there was a way to oxygenate the blood directly?
I suppose you would still have problems with the lungs
and pressure, might fill with water etc.
be hard to transition between states too.
is there a depth limit to it, where maybe the pressure affects the oxygen generating capability?
All I know is what’s in the article.
yeah i thought they added in another gas for deeper dives.
i suppose t could be made with a backup battery as well.
I am focused on the separation of the O2 from the water. This separation of a gas from liquid has been around commercially for about 3 decades. Think Goretex although this actually works backwards from Goretex but don't get hung up on that.
The battery is going to need to power 2 things. First, I am pretty sure that there is going to be some water pumping to keep O2 rich water in contact with the membrane - This will be low pressure, high volume pumping. Second, on the gas side of the membrane there needs to be a negative pressure. The gas pump would have its suction on the membrane side and the diver on the discharge side. What may be really cutting edge innovative on this device is more the battery for powering things than the gas permeable membrane separation.
My bother's an experienced cave diver. After a bad experience a few years back he came to the same conclusion you came to... decided he's rather die in bed.
That leaves a lot to chance. Sounds riskier than the batteries.
It looks like this is just some stupid design CONCEPT. The whole site appears to be full of things like this.

A diver requires 1-2 liters of oxygen per minute, not air.
The article specifically says it’s removing oxygen from seawater, which contains 7ppm oxygen. It would still require 51 gallons of seawater to be processed per minute to provide oxygen at a rate a diver would require.
There are technologies being developed that can strip oxygen atoms from H20 and provide more oxygen more quickly that way, but the device as described by this article will never work.
It is possible the article misrepresented how the device is coming by enough oxygen to keep a human diver conscious, but a gill working on the principle described would be the size of an automobile.
The only reason gills work for fish is that they are exothermic and require a lot less oxygen to sustain metabolism. It’s also the reason no warm blooded sea creatures have gills.
