Following my article a few days ago about sub-zero cooling using a water chiller I have received some correspondence in regard to the statement I made about cryogenic cooling in relation to processor speed.
Because there is a lot of information and mis-information about and there are several threads around where some knowledgeable people are quoting facts that are not quite correct, I thought this article on the future cooling requirements of computers in relation to the CMOS design would very enlightening to many and to most of us who are in this absorbing and challenging hobby.

and another very interesting article about computing in the near future;

BOINK!

Very interesting material. I thought I would send it to the top so no one misses it.

this could use a sticky

That is some very interesting reading...I have to agree with the Sticky request

I don't think that we'll be seeing this in any practical form for quite a while.

The interesting fact is that MIT actually commissioned the first of these new computers at the end of November and according to reports the initial results are very positive and whereas current processors stack sequentially these process simultaneously. They were reporting speeds of something in the order of 50GHz in this prototype so it may not be that long before commercial forms are available. The NASA document talks about 2 years.

i can't help but *bump*
Edit: BTW flounder, thats what they said about 1GHz and even 100MHz

some nice info

i am putting a class together at my university and one of the things we are going to do is cryogenic cooling

my dad has some patents related to some thermal issues of computers that we have permission to use

my Prof. worked at NASA and did these sort of things

and he will be helping out

it has been proven that if you can decrease the temp of a component 10 degrees C, you theoretically double its life

this info was given to me by the head guy at the Dell relaiblity research center

great articles

Another great reason for cooling that hot CPU.
