Purdue researchers want tiny refrigerators cooling your PC {Engadget}
Jul 24th 2008 9:52PM +1 to you sir for knowing of thermalelectrics, some day they will hopefully be another major game-changer in many aspects of our lives.
Purdue researchers want tiny refrigerators cooling your PC {Engadget}
Jul 24th 2008 9:50PM Sure many of you are clearly failing to grasp this concept while others are clearly seeking an understanding. The irony is that this very technology may likely benefit those who are so quick to dismiss it now. As for those who seek to understand it more....
Yes refrigerators do put off heat from the back however by choosing the correct refrigerant the efficiency can be greatly improved (and in modern units this is highly optimized). When converting energy (read heat) from one form to another there is a loss associated with it, this is known as a enthalpy of transformation. To optimize the refrigeration process a maximal enthalpy of transformation is obtained for the liquid to gas phase transition while a minimal enthalpy of transformation is obtained for the gas to liquid phase. This allows the system to pump heat effectively by helping it expel more energy than is input into the system.
As for the rest of it there will be no condensation as this will not cool your chips below room temperature, its not designed to do that at all. It is to be built as a hermetically sealed part of the chips packaging so you'll never have to worry about unless you get careless and crack the CPU's die (in which case you're SOL anyways).
Its pretty cool to see such a story on Engadget as this work is being done down the hall from me and I've seen progress being made on this a while now. My personal work is coming along quite well and who knows, might be featured here someday as well. ;-)

Jul 24th 2008 9:39PM I see him use one every day, I assure he has figured out how to put it to much better use than you have.

Apr 10th 2008 7:28PM I'd like to continue working on a new UI concept I've been experimenting with... this would be great for that... so you should randomly choose me. =)

Mar 31st 2008 11:59PM You're already being sued by them for the color you clearly chose to rip them off, now you go using words like "intel" in your report.... You're just asking for trouble. I hope the courts show you no mercy, you're lower than those terrorist supporting pirates I hear about who sail around the internet stealing peoples files and causing U2 to end up starving like their friends in Africa.
Ok, I'm done...
LG.Philips readying smudge-free computer displays {Engadget}
Nov 15th 2007 6:08PM This sort of thing isn't terribly new. The same sort of behavior is being perfect for use on glass already with the intended use being for automotive windshields, eyeglasses (they are polycarbonate, not glass, but its being worked there too), and lenses, and who knows what else.
My MSE 367 professor is working on this and is one of the leaders in this field. Here is a press release on it, followed by some follow up reading on how this works for those who are interested. Well reading through one of the links it seems that this would be possible on a flexible substrate as well so perhaps this is the same tech.

Purdue's carbon nanotubes could trump heat sinks {Engadget}
Oct 2nd 2007 9:17AM I am pretty certain that they claim that these are easier to manufacture than the chip itself.
