Personally, designing for immersion in salt water is, um, not a sane
choice. Salt water has all of these annoying properties -- it's a good
conductor of electricity, it's corrosive as all hell, it is filled with
all of these really annoying animals and plants that like to grow on
warm surfaces especially, and the pressure increases as you descend in
it at 1 atmosphere per 10 meters) (to name four, two of which I have to
deal with on a regular basis just maintaining a boat that sits on the
surface in salt water for a week. I'm guessing barnacles would
interfere with heat transport...;-)
However, using seawater in the pacific to dump heat into carried there
by cooling fluid (e.g.) is quite reasonable.
