Cool electronics with outside air via hose.

Could be interesting idea... to connect the computer to the outside air via
hose/tunnels.

Except maybe in summer ;)

But in winter it would supply the pc with cold outside air instead of room
temperature ;)

Or you could just get in the bath/shower with your 'dream' PC - PLEASE!

bad idea

one word: condensation -Dave

Yeah. I was in the position of managing various multi-million dollar
supercomputers, and made very rude remarks about the quality of their
real-time clocks. They were anything from 5 to 50 times worse than
my 10 dollar wristwatch.

I agree about condensation... this idea seems quite impractical as
better solutions exist. Though thinking about obscure ways to cool
chips does remind me of this paper... which I actually thought was
interesting.

Which was co-authored by Anant Agarwal in ASPLOS Wild and crazy ideas
from this past year.

Yes, condensation would be a big problem *UNLESS* it is catered for.
Sykfuck's tube should be routed through a condensor stage which collects
the water into a container with a small faucet. The computer user when
thirsty no longer has to walk to the kitchen get some water, he only has
to turn the faucet on his condensation tank.

Consumer resistence to this system could easily be overcome by judicious
use of blinking blue LEDs and a built in ringtone dispenser.
 
Actually I do that now,

I open the window so room temperature drops.

The room temperature was 24.5 degrees at which point my pc starts making a
little bit more noise.

I open door for a few minutes and room temperature drops back to 23.5 to 23
degrees or so and then pc a bit more quiet...

This is what gave me the idea: why not guide cold air from outside to
peecee...

Then I don't have to sit in the cold wind going through my appartment ;)

Because I set both sides of appertment open to get quick air displacements
;)

Somebody mentions condensation which might be a fair problem... but then
again...

Maybe condensation would be at the hose... maybe it can be catched before it
enters pc ;)

Good point.

Condensation would need to be catched... before the cool air can proceed
further :)

Problem solved ;) :)

1) yer watch has a digital output?
2) 5 to 50 .. what units, scale?

There is another problem with this idea:

The air outside could be heavily polluted from car/bus/truck exhausts.

Water + electricity/electronics scare me :)

For bbbbzzzzzzz reasons =D

Bye,
Skybuck ;) =D
 
Last I knew .. condensation only occurs onto a cooler surface, when it comes
in contact with warmer, moisture-laden air. The inside of a warm computer
should
be the last place you would expect condensation.

Once I had to perform a radio system coverage drive test which employed
4 laptop computers, GPS, A/D converters and receivers in a station
wagon. It became apparent in the first 1/2 hour that one of the
computers could not take the Florida heat. So off to Ace hardware I went
to get some flexible dryer vent pipe and duct tape. I used one of the
A/C vents to force air into the keyboard of the faulty laptop and got my
3 days worth of drive data.

Gas lol.

I know it can explode... but it has never happened before... to me at least
and I cannot remember any store of anybody else having an explosion...
except maybe gas leaks... but I don't have those ;)

Maybe an earthquake could cause gasleak but then I would know... cause
earthquake would wake me up.

But I do know stories of people getting electrocuted.

It ain't fun.

Well you should come visit my place sometime and inhale the air outside
during rush hour and such.

Good point !

What if cold air first cools down stuff... and then later warm air comes
along...

The maybe it would start to condensate ;)

No, but many do.

Drift. The major form of error with quartz clocks. 1 ppm versus 5 to
50 ppm. Actually, one particular supercomputer was over 100 ppm.
