Or use the rocket launch technique and spray water across the take-off
area.


Probably less than optimal. *Large clouds of hot, salt water steam
would be an annoyance (at a minimum) to the deck crew. *It would also
be a highly corrosive material that could serious complicate
maintenance of both ship and aircraft.


Use of fresh water would likely be an excessive demand on the
evaporators.


The piping of cooling water suggested earlier would be a better idea.
It would likely be cheaper that major modifications such as a "ski
jump" and permit the continued use of the vertical capability of the
aircraft.


A water cooled heatsink built into a part of the deck designated for "hot"
aircraft makes a lot of sense.


You could have a place underneath to stash beer, like the old sub-
mariners did.


In electronics, we have similiar problems, we usually solve using Al
heat sinks, fan air cooled, as the cheapest. Screw a few Al heat sinks
to the bottom of the locations of the deck permited to take the heat
and engage any fluid to cool it, even water if space is tight, yawn..

Troll them in the water, saves having all those pipes.


In conventional PC's like you prolly have, is a small fan sitting
on the CPU Al heat sink.
In the high watt stuff, oil circulation is used to cool the active
components I've used.
I'm not keen on oil, a friend of mine had a damn transformer
explode on him and was showered with burning oil, it was not
pretty, and is very painful.
Also in my experience, I had a wood stove that started glowing
low red (over heated, but it was cast iron) so I sprayed it with
water to cool it, and that worked good.
A good cast iron is pretty tough stuff, better than malleable at
high temps I'm told.

Learn that steam burns, did you? Let me guess, you're an engineer.
