Making the filters larger isn't enough either.
Remember, you need to BREATHE through them, your lungs are powering them.
The human lung has enough strength to breathe our atmosphere.
Our lungs simply cannot provide enough force to filter our oxygen needs from the water.
That said- with a proper power source and a compact pump, you could have a small oxygen tank that is self-filling. That'd be extremely useful.
#79 - anon (06/26/2015) [-]
With all the electrical equipment you'll have to seal and batteries you'll need I think an oxygen tank ends up being more practical.
User avatar #81 - armwulf (06/26/2015) [-]
I'm not so sure, a small oxygen bottle is safer to store, and much lighter- it would make diving less tiring. As for electrics- you really just need an electric pump with some kind of power supply. Something that can move water in through the "Gill", and push the oxygen collected into the bottle at standard pressure. We can't breathe air that's too high or low pressure.

But something has occured to me- some fish breath passively, what if the filters didn't need a pump? You used MOTION, like some fish and sharks?
As long as you're moving, you're "Filtering" with the gills.
#82 - Capnhowdy (06/26/2015) [-]
most water still doesnt have enough oxygen in it to support a large, warm blooded mammal that is swimming vigorously to maximize flow rates.

and as for a pump to extract O2 from the water, you might as well just electrolyze the water with the amount of energy that shit takes. at lest then you'd solve the O2 volume problem.
User avatar #83 - armwulf (06/26/2015) [-]
Electrolysis requires heavy, high energy equipment.
A pump requires a motor to spin a little turbine and suck in water.
#84 - Capnhowdy (06/26/2015) [-]
electrolysis provides the same oxygen mass per joule of energy consumed as a pump but has the benefit of no moving parts and no, it doesnt need to be very big at all. they are both silly ideas though because you need absurd amounts of stored energy. trust me, im literally an electrical engineer. invest in a SCUBA
User avatar #87 - armwulf (06/26/2015) [-]
Wait, hold the fuck up, I call bullshit.
I get it, you can calculate the amount of energy required for an electrolysis rig to generate X amount of oxygen, depending upon it's efficiency. That's simple.

But there are too many unknown quantities for you to make that assertion for a pump-gill system!
-The level of dissolved oxygen in the water (Varies based on depth, geography, latitude, temperature, salinity, and other factors)
-The efficiency of the gill (What percentage of dissolved oxygen is removed from water passing through)
-The resistance of the gill (The amount of force required to move water through the gill. More resistance requires a larger pump.)

Meanwhile, an Electrolysis rig separates water into Hydrogen and Oxygen, it's separating molecules, which is a bit different from extracting a dissolved gas from a solution!
#97 - Capnhowdy (06/26/2015) [-]
there is 1/10th the oxygen per volume in water as there is in air, best case scenario:

water.usgs.gov/edu/dissolvedoxygen.html

that means a bare minimum of 10 times the flow rate of normal breathing and of a fluid 680 times denser than air. Also, at 300kJ/mol to electrolyze water, you need about 3.5kW to produce 200g/min of O2 which is what you'd get from 300L/min of fresh water. way too much for a human but oddly pretty close to what industrial pumps consume at those volumes.

Engineeeeeeeeer

There's a crystal that can suck the oxygen out of a room and release it again. rt.com/news/193280-crystal-breathe-underwater-oxygen/
#21 - thatonecommunist (06/25/2015) [-]
What if you upscaled it and put it on your back?

if you did this, you could also make it run on electrolysys, so you could stay down forever.
User avatar #48 - vorarephilia (06/26/2015) [-]
That would need electricity. Not sure about size or cost but by that point you might as well just use a tank.
#49 - thatonecommunist (06/26/2015) [-]
There are many ways to generate leectricity from a pack on your back.

I have no idea the size of this, but in theory, if you're generating the oxygen, wouldn't that work better for staying under longer?

I know the pure oxygen dilemma is still there, but this isn't a solution to that, couldn't this be used by say, tiny scale submarines?
User avatar #17 - wotterpatch (06/25/2015) [-]
That's a flawed statement, there is plenty oxygen in water...

This rebreather just doesn't filter out the oxygen fast enough.

Also breathing pure oxygen for extended amounts of time is a good way to die

well instead of having a tank with mixed oxygen and nitrogen we can have this filter coupled to a full nitrogen tank
less expensive to refill and will get you for longer diving sessions
User avatar #14 - elsenortamatoe (06/25/2015) [-]
or, every few minutes you go get some air. beats having less than a minute for untrained people. sell for $50 a pop, make bank

That's exactly what it should be, training for scuba diving.
User avatar #10 - localbees (06/25/2015) [-]
Even if it can't supply you with enough, it could potentially augment a regular scuba tank.
#8 - modreaper (06/25/2015) [-]
I suppose it could be fused with current day scuba gear to maybe lighten the load off of the oxygen tank, making it last longer. Perhaps until we find a way to make it more efficient.

It's really not a HUGE deal or anything, but since you made content about it, I figured, hey might as well acknowledge a fellow fan of the show.

Not gonna jump down your throat and be all "ZOMG READ FANFICS AND WATCH VIDEOS AND BLAH BLAH BLAH"

*shakes your hand* Glad you found some interest in the show, I hope that your experience with some of the fan-made stuff and people with whom you interact is a good one! ^_^

oddly enough i started seeing content on this site first then curiousity took over and now.......
#4 to #3 - seanessytheking (09/03/2012) [-]
Yeah, same here. Only back when the content was like every other post on the front page. I got tired of not being in on the joke, then I did some research to understand the hype and found out some of my favorite voice actors and music producers worked on the show, gave it a shot and well...yeah... :p

Considered your comment virginity taken.

Also congratulation on becoming a brony!
