In theory, you could use a/c to cool your computer. Or you could use thermoelectric cooling like they use in those travel coolers that plug into a car cigarette lighter. From my understanding it is a very thin material that by some process that i am not sure i understand either heats or cools depending on the polarity of the charge applied. So in theory you could line the inside of your case fans with it and the connect it to the power supply that you allready have right there inside your box since it runs off of 12v dc current anyways. You would still need a cpu fan and maybe a case fan or two to draw out condensation but other than that you would have a very effecient cooling system. I have seen this material keep a bottle of soda frozen on a 110+ degree farenhight day. The one thing im not sure about is how cost efective it might be. We (ZomBieMan77 and I) are in the process of looking into this now. When the final stages of development are completed, we will post the results here. If anyone has any suggestions or ideas, please contact ZomBieMann77 or myself. Thankyou.
