at absolute zero a conductor becomes a super conductor, so a cpu at absolute zero would have no limitations

No, that was by using Graphine instead of sillicon.

Actually, only certain materials superconduct at any tempature. Sillicon, the semiconducter used in most computer processors, can only become a superconductor with large amounts (9% of mass) of boron. While there is a small amount of boron in a computer processor to make the sillicon semiconduct, there is nowhere near enough to superconduct.

Ok no. This won't work.

Laser cooling works in 3 ways:

1. interference

atom is vibrating at a frequency. tune the laser to have the same frequency but perfectly out of phase, and destructive interference occurs. Motion goes away, so does temperature. Great for bose einstien condensates, not so great for a huge hunk of solid copper.

2. Ballistics

Atom moving in one direction. Photon moves in opposite direction. they collide, slowing the atom. This is kind of the retarded way to do it, but it sort of works.

3. Ablative cooling.

You have a material. Its very very cold. You hit the top surface with a laser, causing the top atoms to evaporate. The change in phase costs energy, some of which is sucked out of the material, and it cools off. Heatsink doesn't evaporate. I think this method works with like... supersolid helium.



None of these will work for doing anything like cpu cooling. You might be able to sink the processor in a liquid helium environment where you evaporate the top of the liquid, and get down to 1 or .5 kelvin, but that goes out the window the second you run current through it.

Nope, liquid helium wins.

Then why does electricity conduct better the lower the temperature goes, and why do most super conductors only function at extremely cold temperatures? AFAIK, and I may be wrong, but I think electricity still conducts at absolute zero.

Oh, and below a certain temperature (not sure exactly, but very cold) MOSFETs start to degrade and be destroyed

The lack of Wave vs Particle Duality theory in this thread makes SLeeZeY feel sad.

Why? And why can't you cool the air going over the heatsink instead of the heatsink?

Most of the time, when you shine light on something it heats up.

Heres the trick with laser cooling (it has a cute little game to play where atoms fly in and you hit them with photons)

http://www.colorado.edu/physics/2000/bec/lascool1.html

For this to work, you've already cooled the molecules to liquid-helium temperatures-- or below. theres just too much random motion at room temperature or higher for a laser cooling to work.

read the wikipedia on laser cooling... there is just a massive disconnect here. laser cooling is used to observe quantum mechanical effects in a plug of material, something that isn't possible except at very low temp in a bose einstien condensate.
