This is circulating like mad, almost like drone pizza deliveries. No more lugging tanks around? http://www.dailymail.co.uk/sciencetech/article-2540610/The-gadget-turns-FISH-Mask-extracts-oxygen-ocean-breath-continuously-underwater.html

    It'll need to go through 200 litres of seawater per minute to supply enough oxygen. That won't be very practical.. you get rid of the oxygen/air tanks but you'll have to add a big compressor/pump and energy source to run it.
    Nobody has actually made that mask and I suspect it'll stay that way for some time.

    ScubaPro stock dropped 10 points already! :)

    Molto interessante, but do you die when the battery dies?

    What a load of fish droppings!

    'Micro battery' that's "30 times smaller than a current battery and charges 1000 times faster"...
    Are they using a renamed supercap?

    And a microcompressor to compress the oxygen for later use?
    Honestly, are they aware of the cost of miniaturised compressors with any reasonable lifespan?

    Sucking in water from tiny holes?
    200L/minute?
    Yeah, right...

    Better hope the water is very, very clean...
    And stay away from seaweeds...

    I wonder if the inventor will test it first.

    What? You mean water isn't the only thing this mask is meant to suck in?

    4500psi?

    Darn!

    That is 310BAR.
    If my memory isn't completely out of whack, I think the pressurized air cans used in Sidewinder 9L missiles topped out at 350BAR.
    Cleaning, hydroing and filling those little grenades was a pain in the...

    Mixing up a batch of 20% 20mm for the F-16 was considered relaxing work.

    The technical aspects threw up some red flags. The illustration was pretty uninformative. A fish has gills sized proportional to its body, I'm not sure how efficient gills are though. That thing just seems way too small to be powered by human lungs. Maybe it only works to a couple feet under for snorkeling.

    It seems to be nothing more than someone describing how they would like it to work, with a nice picture and model. I can't see what he "invented" that hasn't been dreamed up by thousands of scuba divers already, myself, one of them.

    No not 4500psi he means 4500, psi tanks, flooding the market with so many tanks may not be a wise idea, pressure selling puts a lot of folk off
    As Tull would say....."Aqualung my friend", is what you need! :smile:

    Translation to English please. Might be a useful phrase.

    I think that was the typewritten equivalent of a 'rimshot'; typically given after a somewhat 'lame' joke is delivered. The audio is a couple of strokes on a snare drum followed by a quick stroke on the cymbal.

    "Boom - tish"

    How much more English do you want it. http://www.boomtish.co.uk/

    Speaking as an Englishman it was years before I realized what "rimshot" was supposed to mean. It always sounded like some weird sexual activity.
