"Like A Fish Underwater" new way to breath under water without oxygen tanks

[imasinker]

I'll stick to the Al 80's and steels for now....been safe and good enough for me... If humans were meant to breath underwater, we would all have gills.

Ironic, theroy says we all evolved from sea life,crawled out on land learned to stand and walk, hunt, creat ways to better live and now sems like we all want to find a way to get back into the water and stay longer.... reverse evolution...lol.....

 

[maged_mmh]

not only reverse evolution...
the grey haired genius stated that time is a dimention, thus it has an axis and all axises are not straight infinite lines instead they're closed circles.
so, maybe we are anywhere about to complete a 360 deg. lap.

My understanding is that the guy's a nut and the idea is not really practical.

Has anybody done an analysis of the volume of water that needs to be processed to get sufficient breathing gas? And the energy required to do so? And how that energy requirement compares to simply doing electrolysis of the water to get the replacement O2 needed for a rebreather?

The article says that a 1 kilogram battery will allow a 1 hour dive time. If true, that is superb.

It sounds scientifically sound. It's simply an engineering problem to be solved. Just like scaling up from a bottle rocket to a lunar rocket is simply an engineering problem.

Most of my dives have been without an oxygen tank.

Would be great if it could be done, or shall I say when. I shiver to think of the cost of such a system like that, such as going from open circut to closed circut. Interesting to see what evolves from this, so a subject worth keeping up on.

It'll start big and cumbersome, then as production ideas improve, they'll be made smaller and smaller, until they make one the size of a deck of cards that can be surgically implanted in your chest. They'll call it the AquaLung...

And ScubaBoard will still be around... and there will be threads about using your implanted AquaLung with a snorkel or not...

And whether or not you are qualified to sling an aluminum 30 pony as a redundant air or not.

nawwww it'll come with it's own back up....lol

It seems an old news that "Like A Fish Underwater" new way to breath under water without oxygen tanks...

As a scuba diver, this looks cool. but also dangourus. the amount of deaths using re breather is huge. and this is even more complex...

I have never used an Oxygen tank in the water, and while I am not rebreather trained, I don't think your general statement on those is fair at all.

But without 'radial' prototypes, we would probably still be cruising round on horses and living in caves.
I'm sure one upon a time SCUBA was condidered 'wildy dangerous and impractical'.
I say good on him, and hope it makes it to a point where we can all use it

Down with tanks!

A slightly more detailed description.
IsraCast: Like a fish - underwater breathing system

I'm all for out-of-the-box approaches, but I want a Bigggg battery on mine.

um, ok?

I have seen before what people say "lake turned over" and usually results in dead fish floating.

Is it possible that some water could have no oxygen in it?
How would you know until it was to late?

That's one of the reasons for the pony in the illustration.

Oh yeah, them pesky Oxygen tanks again.

A centrifuge big enough to process enough water to supply sufficient gas to keep up with the SAC rate of a human would be the size of a small SUV.

Tankless Underwater Breathing Apparatus... TUBA right?

Maybe I'd like mine nuclear powered.

nawwww it'll come with it's own back up....lol

It has a pony; look again. I want a 80 cf pony with mine.

The first computers took up a house. Now we have one infinately more capable that I can carry in my pocket.

As others have mentioned, you have to start somewhere. How else are we going to get to the little horse bit you stick in your mouth and breath underwater like the Jedi's use (did I really just go there ). Shoot me now.
