Your absolutely right Dan...
As one descends it is a plan to just add air and with the slots or holes
the air can escape ,,,,,the slots can be set just a little bit down and this
allows the air to escape....but the slots are set so that one does not need to
be so critical as to the amount of air that is added to slow the doesn't...It
works going up...and going down....No matter how one builds a ballast system
it's necessary to add air to slow the descent....DJB
At one atmosphere of depth, your air will
compress to 1/2 and be replaced by water. Are you planning to compensate
by constantly adding air? If not, where does the air come from
that will be automatically "burping out as you ascend."
I agree it sounds like a nice system for a smooth
ascent but, unless I don't understand your design totally, it's not a good
system to descend with. It's safer to go "ballistic" then like a
rock.
