'Ionic Breeze' Could Cool Chips 250% more efficiently

Researchers at Purdue recently demonstrated their new "ionic wind" technology that can improve the cooling rate of internal computer components by as much as 250 percent.

This is the sort of dramatic cooling improvement needed for the computer industry to develop lighter weight computers and laptops that are still powerful enough to run high-intensity programs without frying your CPU.

The researchers tested the experimental technology on a mock computer chip for observers. It works by generating ion movement between two oppositely charged electrodes. Electrons colliding with air molecules create positively charged ions that then flow toward the negatively charged electrode producing an "ionic wind." This breeze increases the airflow on the surface of the chip, cooling it down.

The story is too old to be commented.

That is a funny headline considering the "ionic breeze" is a horrible product that doesnt move air at all.

Isn't this the same crap that they try to sell you at The Sharper Image and in airline shopping catalogues?

I so totally hate that ad, hair growth ads are even worse

...my favorite gimmick in those catalogs are the electric nose-hair trimmers.

I actually read something similar on Slashdot last year. Back then it didn't really work too well in practice but they may have made significant improvements.

And ya, the commercial Ionic Breeze unit doesn't move much air, and it is NOT quiet.

if used for the right thing. Ionic "lifters" or "floaters" have been around since the sixties, usually with some crackpot calling it an "ant-gravity" device. I remember an article in Popular Science or Popular Mechanics when I was in junior high about using them to lift radio and TV relays into the upper atmosphere. World book encyclopedia used to have an article on rockets or space or something that included science fair type plans for an "Ionic Rocket" that used this principle.

I have serious doubts, however, that the technology could move enough air through the small areas needed to do the job without causing electrical arcing. If you've ever seen film of a "lifter" in action you've seen the kind of sparks (inches to feet in length) they can produce.
