Hi Jon.
I have a couple of thoughts/questions on the
pressure compensation of the pump. Would the pump even need
pressure
compensation? If the pump is fully flooded at
ambient water pressure why would there be a need to compensate it?
The other thought/question I have is this...in
theory, a pump as you envision would act to compress the water and
exert it outward in a jet resulting in forward
motion utilizing the principle of for every action there is an equal and
opposite
reaction, correct? However, the pump has a limit to
the force it can exert upon the water in creating this water jet
correct?
So if you were deep enough for the outside ambient
water pressure to equal or exceed the same pressure the pump exerts
on the water it pushes thru the jet, wouldn't this
actually equalize and stop the pump from working? Just a thought, I
haven't
really thought this totally thru. What do you
think?

psubbers,
I had a thought today about motors for
subs. Would it be feasible to create
a motor on the theory of a
reaction turbine, using ambient water surrounding
the sub. My thought
was this:
1) Mount a high pressure pump either inside or outside the
sub.
2) The pump takes ambient water from it's environment and ducts it
via hoses
(or piping) to the turbine (squirrel cage, francis turbine,
pelton wheel?)
I suppose you could forego the turbine and just pump the
water through a
nozzle jet like Cousteau's saucer sub used. Anyway,
the attraction I saw
was no need for pressure compensation except for the
pump which would be
pretty easy to do.
Any
thoughts?
Jon
