I saw this news article yesterdaay about the design of a solid state cooling fan with NO moving parts.

Some info and a video in the below links:

It is very impressive to see the video of the fan in action. Of course there are concerns about interference that might be inevitable with this design, but it is a very very innovative idea. I hope to see this in future computers.

Yes, very interesting indeed.

Thanks for the info.

I remember from some of the copier factory training classes I've been to they harp on the fact that a byproduct of corona discharge is ozone which is supposed to be a health hazard. So much so that all copiers have ozone filters to cut down on the release. Don't see that mentioned here

A very interesting homemade version.

Neat technology, but what is the practical point? With a good fan (decent bearings), the vast majority of the noise is that of air itself moving, which isn't going to go away. The power required for a fan pales in comparison to what wireless technologies are eating up. Potentially smaller footprint is the only benefit I see - and machines which can't fit a fan tend to use CPUs which can go fanless, anyway.

Nitpick: "solid state fan" is a bit of a oxymoron.

Reliability - for one. No moving parts means lesser chances of failure. I agree that power savings (if any) is not going to be much .. also as Mike mentioned, safety is a concern too.

Isn't this the same idea as those things from The Sharper Image?

EDIT: What is a corona discharge? Sounds like something that happens after a night of bar-hopping
