[sclug] sclug Digest, Vol 93, Issue 7

[Neil Haughton]

I'm intrigued by this thread and always open to technological advances but I
like to understand them too. Can someone explain to me the benefits of
cooling a PC with holy river water? Does it have a higher specific heat
capacity, or possibly better thermal conductivity, than your conventional
unholy water?  Or does it add a certain aura to web pages served up by the
server, that a conventionally cooled server (for example) cannot provide?

Maybe it protects the server from Vampires. I've heard it said that such
protection is one benefit offered by holy water, and it's probably better
than driving a stake through the heart of an infected processor, which might
be terminal - although I've never tried that so I can't be sure.

Neil.
