Alan,
That
would have to be the silliest idea you have come up with. Heard of
bends, decompression?
I am thinking that
it would be possible to turn a K250 or any
sub
into a semi-ambient
for an emergency situation where you needed
Example --- Go down
to your 250 ft limit & turn on an ambient
system
at that
point, this pressurizes the cabin as you progressively
descend.
Theoretically you
could go another 150ft, down to 400ft.
I guess you'd need
a lot of tanks for a K250. Maybe more practical
for
Cliffs sub wich is
a bit smaller. You would need a dive computer for
decompression
calculations, an over pressure valve, a modification
of
the life support
system wich could be as little as increasing the
O2
flow into the
cabin. Also the instrumentation would need to take
75psi.
The ambient
equalization system could be set up by having a outside
pressure reading
& an electronic system that fed air into the hull when
the outside
pressure was more than 125psi above the inside.
