Wind tunnel effect through house to cool electronics.

fill your house with freon. very well behaved stuff. except in the
atmosphere.

There is a liquid suitable for electronics, called Fluorinert. I saw
a demo at an electronics show, where a TV set, with cover removed,
is half immersed in the stuff, and the TV still works. (It cannot be
fully immersed, because the dielectric strength of the liquid, is not
high enough to take the HV on the red insulated wire.) This solves
the water problem, but as a liquid, there are still things in the
PC, you cannot use it with (the hard drive).

The stuff is pretty expensive, like $250.00 a gallon or so.

And I didn't know there were different versions. I see one of
them, freezes at -110C.

Yes, we use it regularly in the items that we manufacture.

The ones we have emit an annoying intermittent beep before the battery runs
flat - great as you are warned.

Due to a regulatory chance over a decade ago. Must be a very distinct
sound.

Interesting. back when we were so carefree, we used to use freon in
the lab as a terrific nonpolar solvent. what i didn't know previously
was that there were different versions of freon as well, with
different boiling points; what we used had a lower boiling point
specifically so it could be used as a solvent at room temperature and
pressure, not pitched as a refrigerant. and yet, easily evaporated
off. it was a sad day when we had to give it up. maybe fluorinert
would do the job. anyway, i'm out of the biz now.
