As far as I can tell, they are just using the salt water to reject the heat
to. How they get the heat from the cpu/hot bits to the water is not
A passive heat exchanger would make energy sense... but would cost a bomb
in engineering... maybe direct fluid cooling (asetek) with a
heat-exchanger to the salt water?
Either way, its stupid. They could just easily pump the cool salt water
from the ocean into a DC, reject heat to it using the same methods... and
pump it back to the ocean. Since no real delta in height, it would be
efficient in energy.
OR... just use a boat...
