tfot.info — A new type of ultra-thin, silent cooling technology for processors is being developed by Kronos Advanced Technologies in collaboration with Intel and the University of Washington. In two years, this new technology might replace existing cooling fan technology in laptops and other portable devices, making them more reliable and far quieter.

This needs to be dugg!?!?!?!?! WTF this is some important s**t. This is something major, WTF is going on. I wish I knew more people that use digg more personaly so that I could send them this story

Yes, maybe for laptops. For desktops water cooling still beats whatever kind of air cooling technology these guys come up with.

2 years?! noooo, i want one of those noiseless cooling device now! ;)

I love that guys claim of 325.00 CFM

even for laptops... i don't think it is currently possible to use. have you looked at the power voltage used ?1 to 8 KILOVOLTS !!and that is DC, not alternative !maybe that is why they say it will take AT LEAST 2 more years until products using technology can be marketed.even if it uses 0.1w for 1cm square as they say in the article... you need some beefy circuits to provide constant 1kv to 8kv of power to this beasty, especially since you need to up-convert the puny 12, 24 or 36 volts that a laptop battery currently deliverseither that or build a nanoscale nuclear plant into the laptop. Isaac Asimov might have been right on the money when he introduced his personal force shield generator powered by such a nuclear plant... i think it was in his "Foundation and Empire" book.

I don't get it. The article says it works on Carona Discharge. About 3 KV/mm of electric field strength is required to generate carona and the process involves sparking. It must be ionised air and not a Carona.

it's pretty easy to get low current, high voltage circuits. for example stun guns are in the tens of kv and powered by a 9v battery. you just generate an ac or pulsing dc and start stacking diodes and capacitors. At some point it'll start arcing and you'll have to stop or find something better than air to seal things up. I'd be more concerned with ozone.here's some example circuits look at the bottom of the page: <a class="user" href="http://www.play-hookey.com/ac_theory/ps_v_multipliers.html">http://www.play-hookey.com/ac_theory/ps_v_multipliers.html</a>
