Exosuit Pushes Limits of Undersea Exploration - by Scientific American

    My name is Michael Lombardi, I'm the Diving
  • 0:11 - 0:13
    Safety Officer at the American Museum of Natural History.
  • 0:13 - 0:16
    The suit is made of a hard aluminum.
  • 0:16 - 0:19
    It's (inaudible) alloy. So you're essentially
  • 0:20 - 0:22
    inside of a pressure vessel, you're inside
  • 0:22 - 0:26
    of a submarine and that space is not compressible.
  • 0:26 - 0:28
    So that's really the key with removing pressure.
  • 0:31 - 0:33
    If you were in a compressible space, so for
  • 0:33 - 0:35
    instance, if you're just in a wetsuit, the
  • 0:35 - 0:37
    human body is exposed to pressure. It's cause
  • 0:37 - 0:40
    for a whole host of physiology problems.
  • 0:40 - 0:42
    So we eliminate this problem through physiology,
  • 0:42 - 0:45
    we open up a whole new dimension for exploration.
  • 0:46 - 0:48
    All the life support is self-contained on the suit itself.
  • 0:49 - 0:51
    You're essentially using an oxygen rebreather
  • 0:52 - 0:54
    inside the cabin. So you're recycling the
  • 0:54 - 0:57
    cabin gas by carbon dioxide is removed chemically
  • 0:58 - 0:59
    and oxygen is replenished to match your
  • 1:00 - 1:02
    metabolic rate while at work or at rest.
  • 1:02 - 1:04
    If we were to wet dive to these same depths,
  • 1:05 - 1:07
    it would require a very complex use of
  • 1:08 - 1:10
    mixed gas, so typically, oxygen, nitrogen,
  • 1:10 - 1:12
    helium, to allow us to dive very deep.
  • 1:12 - 1:15
    I've had a lot of experience doing that and
  • 1:15 - 1:17
    you end up against a wall very quickly in
  • 1:18 - 1:19
    terms of how much time you have and depths
  • 1:19 - 1:21
    to do these things. So in the Exosuit,
  • 1:23 - 1:24
    you're at surface pressure, you're recycling
  • 1:25 - 1:27
    the cabin gas supply and you're breathing
  • 1:28 - 1:29
    the same (inaudible) as you are here and
  • 1:30 - 1:31
    you have, you know, a 50 hour supply of.
  • 1:31 - 1:33
    So here, we have a tool that can crossbridge
  • 1:34 - 1:37
    any number of industries and solve
  • 1:37 - 1:38
    problems that we've never been able to
  • 1:38 - 1:40
    solve before.
  • 1:40 - 1:42
    One, Two, Three.
  • 1:42 - 1:43
    (Splash)
  • 1:43 - 1:46
    That's me in the flippers, Michael Moyer,
  • 1:46 - 1:49
    editor for Space and Physics and Scientific American.
  • 1:49 - 1:51
    To understand why I'm diving over the side
  • 1:51 - 1:53
    of the boat in search of my next meal,
  • 1:53 - 1:54
    you've got to step back in time.
