Odd-Looking Scuba Mask Turns You Into a Fish

What was that movie with the actor Ed Harris where he played a character that had to fill his lungs with a liquid to breathe at a certain depth under the sea???

His initial reaction was way less than I think my reaction would be to my lungs being filled with a liquid.

I so want to try this out ...on someone else. I'm convinced with enough training, time and a little force I could get someone to breathe in water. I am yet to find a volunteer though.
 
Cool concept. But just like a lot of other ideas - this one has too many what-ifs.

I remember reading a study on synthetic blood based in crocodile hemoglobin.
Supposedly that would allow for oxygen retention long enough that you could hold your breath for 30 minutes.
Sounds great, but freediving like that? Having your lungs compressed to the size of your fists for a minute can't really cause much harm. But 30 minutes? doesn't sound like a good idea. A diver would still need to have a breathing rig, even if just to keep his lungs equalized.

This could be a nice concept in a backpack re-breather where it harvests oxygen out of the water, but I wonder if the weight and size of the system would make it worth replacing a oxy tank. Maybe in deep dives, but then we also start asking questions about dissolved oxygen content at certain depths.
 
But that's why I said that it might work if you remain in shallow water conditions like in shallow water emergency conditions or in shallow water recreational activities.

It seems to me you people are wholly dissing the device because you can't dive down into the Mariana Trench with it.

But I want to see sea monsters!

it's punted as a replacement for SCUBA apparatus, not a snorkel

Spoilsport.
It would be cool for recreational dives though.

When scuba diving there is a very particular method of breathing in through your nose and out through your mouth.

It's a very difficult skill to learn and that's what they are referring to, not simply a case of breathing normally.

Think they've used it for premature babies and people with ards.

because if you are the above then you're in serious trouble when diving

Dafaq? In through your nose?

I breathe in through my mouth because that's where the reg is, and out through my nose and mouth together to keep the mask equalized.
 
A diving mask? B/S a mask goes on your face to create an air space between your eyes and water so one can see. I call this a form of filter regulator cos as we all know pure O2 is toxic. Good idea but can't see it working at all looking at the size of fishes gills and our lungs methinks it's more bs than anything else.

No, it won't work... not even in shallow water. Not in any water... nothing... nada... f0kol.

Energy, Storage, Electronics size, and Required Volume of water are your biggest problems.

-Energy
How much energy do you need to:
1. Extract oxygen from water extremely frikkin rapidly
2. Compress the air. What amount of power can a micro battery possible give?

-Storage
We needs storage to store the compressed air. How on earth are you going to get a micro compressor to store the air in any appreciable amount? Never mind power it.

-Electronics size
Just how? This isn't an issue about size in itself... but how much can something that small provide? Small Compressor with tiny tiny piston? Take one breath and think about how long it'll take to fill your lungs from a miniature compressor.

- Water Volume
You'd need to process a massive amount of water to extract enough oxygen for a human to breath. We're not fish. Our bodies aren't adapted to breath small amounts of oxygen.

"As sea water contains 7 ppm oxygen,[citation needed] 1,000,000 kg (1,000 tonnes) of sea water holds 7 kg (1,000 short tons holds 14 lb) of O2, the equivalent of 5,350 litres (1,410 US gal) of oxygen gas at atmospheric pressure.

An average diver with a fully closed-circuit rebreather needs 1 liter (roughly 1 quart) of oxygen per minute.[8] As a result, at least 192 litres (51 US gal) of sea water per minute would have to be passed through the system, and this system would not work in anoxic water.

Good luck getting that into a mask.

Here's some more info on current testing with artificial gills:
