- Otto, on 10/12/2007, -0/+5The ozone emitted by this sort of thing is very small. Yes, you're ionizing the air, but the ions move to the other terminal and give up their charge there, completing the circuit.
- fishbert, on 10/12/2007, -0/+5Am I the only one with whom the idea of ionizing the air moving around electronic components doesn't sit well?!
- NetJoe, on 10/12/2007, -0/+5it'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: http://www.play-hookey.com/ac_theory/ps_v_multipliers.html - CraigB12, on 10/12/2007, -1/+5My freshman year roommate in college actually explained this idea to me and did a design project for it. My argument was the ozone emitted is bad for the environment, similare to the air filters on the market for home use. Guess we should have patented the idea 5 years ago lol
- ellisgl, on 10/12/2007, -0/+3Smog and Ozone (O3) are not the same thing.

Voltage is meaningless in terms of power consumption (yes converting power takes up power but its usually declared negligible).
It's all about the watts.
.1 watts is a drop in the bucket compared to 20-70 watts for a processor.
It beats the 5 watts required for some of the more powerful CPU fans.
Some how this technology doesn't feel laptop safe to me. Something about having a corona discharge within inches of my man hood scares me, but so does using a Sony battery...

Essentially, somebody took one of those ionic "air cleaners" and used the compenents to create a cooling system based on this same principle. It was completely silent, which was nice. I'm looking forward to seeing this technology becoming more widely adopted, especially for GPU cooling.

I think this was the article I read. - tenmenkilled, on 10/12/2007, -0/+3I'm all about removing pet dander from my PC!
- dAbReAkA, on 10/12/2007, -0/+32 years?! noooo, i want one of those noiseless cooling device now! ;)
- eyeats, on 10/12/2007, -0/+3Inventgeek made two of these, here is Version 2, a homemade cheap version
http://www.inventgeek.com/Projects/IonCooler2/Overview.aspx - jshusta, on 10/12/2007, -0/+2Did you mean: peltier
- ahhell, on 10/12/2007, -2/+4Awesome.
Finally some relief from fans. - inactive, on 10/12/2007, -0/+2Yeah, it also generated smog.
- EBFoxbat, on 10/12/2007, -1/+2Surely there is still the sound of air moving in a volume and velocity that is sufficient to cool a CPU.
- t1da1, on 10/12/2007, -0/+1thats the one I was looking for, thanks for a more direct link
- Kahnza, on 10/12/2007, -0/+1I'm always up for quieter more efficient cooling solutions. Bravo. :)
- Topher06, on 10/12/2007, -0/+1New technology? What? I heard about ionic wind about 10 years ago on the discovery channel.
- MadScientist420, on 10/12/2007, -0/+1That's what doesn't make sense to me. You use an electrostatic device to cool your computer but won't it collect TONS of dust just like the ionizer air cleaners out there?
- thcobbs, on 10/12/2007, -0/+1sooo.... this gonna be a peltair device with some sort of ion differential system
- haooken, on 10/12/2007, -0/+1I'll stick with Nitrogen :)
- tylerni7, on 10/12/2007, -0/+1The thing I don't get is wouldn't the high voltages mess up the processor? Just a little spark (which is very easy at that voltage) could make it completely useless...
- ellisgl, on 10/12/2007, -0/+1I love that guys claim of 325.00 CFM
- unicornhunter, on 10/12/2007, -0/+1Great, then I'll have to buy a space heater
- kingygk, on 10/12/2007, -0/+1I remember reading about these a few years ago. Cool stuff. I cant wait to buy one for my new dual core rig!
- TVarmy, on 10/12/2007, -0/+1I feel I should mention that, for the record, air purifiers like the Ionic Breeze don't do squat.
- thcobbs, on 10/12/2007, -0/+1That too :)
- okvol, on 10/12/2007, -0/+1Ozone is a component of smog. I lived in LA for a while. But, this could be hazardous in a household environment. Who out there replaces the ozone filters on their lazerjet printer? Did you know that HP was required to install these on the LJ V1 because the ionizing voltage levels for the toner generated ozone?
Yes, the ozone levels could be very bad for you, especially for young children and the elderly. It can locally damage your sinuses, cause you eyes to water, and decompose some plastics prematurely, yellow your paint, and do all kinds of other nasty stuff to your house.
There are better ways to do this function. Just move along, and ignore this idea.
Do you notice that the new Ionic Breeze machines include an ozone reducer? - Rootman, on 10/12/2007, -0/+0If I'm not mistaken isn't this the same "effect" that they were looking at on Myth Busters a few weeks ago? The "Anti Gravity" myth? Seems they set up a square of wire and tin foil that "flew" because of the coronal discharge moving the air fast enough to lift the object. It wasn't "anit gravity" but it was cool none the less.
- echoforever, on 10/12/2007, -0/+0I 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.
- dasilva333, on 10/12/2007, -0/+0This was already done, there was a DIY ionic cooler last year, its not that great the CFM that it could push was the equivalent of about a mid-end hsf.
- dasilva333, on 10/12/2007, -0/+0there it is: http://inventgeek.com/Projects/IonCooler/Overview.aspx
not that great - Keyframe3D, on 10/12/2007, -1/+1I thought ionization attracts thunder?
- Jolls, on 10/12/2007, -6/+3i dugg it, just for you!
- 0004, on 07/04/2008, -7/+3even 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 delivers
either 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. - ynggrsshppr, on 10/12/2007, -10/+2Yes, maybe for laptops. For desktops water cooling still beats whatever kind of air cooling technology these guys come up with.
- Sethwm2, on 10/12/2007, -11/+1Dude this is going to be the largest change in cooling technology in a while. This is something that I am going to get for my Opteron 165 so I can overclock More more MORE!!!
- Sethwm2, on 10/12/2007, -21/+1This needs to be dugg!?!?!?!?! WTF this is some important *****. 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
