[PSUBS-MAILIST] motor thought

["Jon Wallace" <jonw@whoweb.com>]

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
