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

[Hoomi]

If it has to operate on electricity, then what I want more than the Jedi's UW breather apparatus is the power source for the Light Sabre. When I think of just how many kilowatts of power it would take to just heat up a huge metal blast door, let alone quickly bring it to red-hot molten condition, and that this much power is contained in something the size of a large flashlight, I think, "Give me an electric car with a Light Sabre battery, and I'll drive for the rest of my life without ever having to recharge!"

Hook that power to your UW breathing device, and it will last forever while also powering your lights and scooter.

I think I spotted a Spare Air hanging on his belly button...

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

Don't hold back. Tell us what you really think.

Like other have said, we need innovators, even the wild eyed types like Dr. Emmet Brown!
I’m sure somewhere up in Eureka, they already have a breathing device that allows hours of dive time.

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?

The same way people find out that the pocket at the top of a cave doesn't contain EAN21.

We have a nearby lake that doesn't turn over (ever) and contains a layer of hydrogen sulfide. The top layer is really nice and is a popular for swimming (it's a state park), however the people don't realise that underneath is stuff that would kill almost anything, and certainly wouldn't sustain human life.

Science fact started out as science fiction. The theory is sound, however I will pose another direction. Similar to fuel cell tech, how about using electrolysis to separate the hydrogen and oxygen molecules from the water. breathe the O2 and expel the hydrogen. or better yet use the hydrogen to power the machine. That's how the Jedi's do it.
just a thought.

Hmmm, I'm quite sure that in the early pioneer days of scuba, many thought the same thing about a skinny big nosed french man named Jacques Yves Cousteau. For that matter a writer named Jules Vern who wrote about some impossible underwater ship.
It's not a question of IF this will come about, it's only a question of when. I don't know anything about this guy personally, and maybe he is a total wack case - could be. Then again, would he be the first total wack case to come up with a good invention?

Safe Diving,

...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.

Awwww... the British have had that for 40 years... didn't you see Bond using it in Thunderball?

If I remember correctly from the last time someone announced something like this, it would take something like 70 gallons per minute to supply enough O₂ if they are just using dissolved O₂.

The only way something like this could be compact and not pump huge amounts of water would be to use electrolysis, which would take a lot of power to do at a breathable rate.

Plus, in either case, you still need a diluent tank.
