Heres my idea

[Liquid_Radiation]

Im going too blow alot of stuff up
or myself this may not even work
I think i will have a problem with heat
But here it is Im going too put my computer in a case and pull a vacume about -31 inches
absolute and see what happens
A light bulb has the same properties
soo we will se what happens
wish me luck cross your fingers
I dont think there will be any elements too create condensation, Hope this works, bye for now post I will post pics this weekend
Later peeps, LR

hmmm interesting idea, if you can pull it off... supercooled vacuum... but what happens when it heats up?

[Joe]

In a Vacuum you will actually have MORE heat build up on objects cause there will be less air in the case to carry around the heat. ( but at the point of creating the vacuum you will get some mild cooling ( lower pressure - lower temp ) Interesting!

MM thats why i said i would probally have a heat problem

ja, nice heat problems.
With a vacuum, there won't be anything to remove the heat off the components, so you will need to cool EVERYTHING, right down to your chipset, because you won't have anything else cooling it.

Damn... you guys are nuts

[Freakyfrank]

hmmm
dont light bulbs use a low press gas?
(no not oxygen)

i thought that's why they dont burn up.. not because of the vacuum

[Joe]

The reason they don't "Burn Up" is that Oxygen is a caustic gas ( quite harmful to metals.. ala the reason yer car gets skin cancer

Removing the Oxygen from the atmosphere in the light bulb eliminates the oxidizing affects on the bulb and increases its life span by ALOT!. Also different gasses can be put in to change the way the light behaves ( like Halogen, Xenon, Sodium Vapour)

From what I know the light bulbs are at a vacume but not a total one ( the glass would need to be like 1" thick if it was at -14.7 PSI below sea level pressure) So it may be at a slightly lower pressure, but just filled wit Nitrogen/CO2 or gases that prolong the life of the lightbulb.

also remember that a light bulb is designed to keep heat on the tungsten filement, that way it glows brightly. If the tungsten where cooled, it wouldn't glow at all!.

hehe, glowing mobo chipset, that's great. . .

a lightbulb is usually filled with argon or another noble gas-they are mostly inert so it prevents chemical reactions from working inside the bulb

Ok, so what happens in the opposite situtation - as in high pressurized container?

I'm just curious now from seeing the other responses.


If I follow the logic correctly - the higher air pressure means more heat carrying capacity of the air. But, how do you cool that pressurized air? Air-to air heat exchanger?
