"While
this technology does well moving air to a higher velocity than
traditional fans, what it lacks is being able to generate any kind of
real pressure. Pressure is needed push air into and around things like
the fins of a heat-sink (or worse a dust clogged one), or a wire-mesh
filter, a finger guard. While this is a good step, until they can
create one that generates air pressure, this technology will never be a
replacement for traditional fans."

"Did
you look at the graph? It in fact generates plenty of pressure, more
efficiently than any mechanical fan of equivalent size. There wouldn't
seem to be anything in the design that precludes larger versions from
being built, though I don't suspect it'll be replacing case fans in
towers anytime soon.
I guess those Ionic Breeze gadgets were good for something after all."

"While
I commend the scientific efforts, and think this is an excellent
breakthrough, I have serious issues with their particular goal. The
basic issue with plasma is that when you charge the atoms in the field,
the resulting state of matter emits HUGE amounts of electromagnetic
interference. "Corona wind" is similar in nature, if not exactly the
same, to the solar wind phenomena that the sun puts out. Placing even a
"micro" amount of plasma in such a close area to the transistors on a
processor will surely cause all kinds of data corruption. I'm happy to
see they're trying coming up with new solutions to the problem, but I
for one will never put charged plasma inside my computers to cool
them... unless of course we get to the light-based computing everyone
keeps promising is coming. It might work then... but who knows? "

"Just
for the record, they are not the first who encountered this effect. The
effect has been used to create fake ufo's, it was even on mythbusters
TV. Just telling this before they think it can be pattented it's not
their idea to change airflow by use of high voltage. Nor it is the idea
to cool something with air.
....The patent hater...
Without patents and can become cheap. anyway lets hope it's
electromagnetic radiation doesnt interfere with the to be cooled chip"

"The
EMI due to discharge won't affect the chip, or the transistors in any
way. The effect is on the physical copper traces, not the silicon.
Introducing noise on here will create jitter and other undesirables,
but a good PCB design (already present in every motherboard I know of)
includes a ground plane to.... reduce the effects of EMI. At worst
they'll have to add a small amount of EMI protection on the high speed
regions, at best it will have negligible effects on performance."

"I
think this would be a great idea, especially since I have had problems
with fans before. The only problem that I can see is the generation of
Ozone gases, which is not good to breathe in at high amounts. This is
basically the same way that the Sharper Image Ionic Breeze works, and
the problem with those is the fact that it generates ozone gases. "

"Not
the fact that the mechanical fans listed here are in mm not cm. This
are the tiny little fans like the ones you'd see on an old 486 chip,
not the big 8 or 12 cm fans on today's desktop CPU coolers.
Also
notice that when put under pressure (as other posted here) like when
dust builds up etc, these solid state fans lose flow very quickly,
stopping all together at 20 Pa where the mechanical ones would keep
going at more than double that pressure. Add an ultra high speed
mechanical fan that blows the dust out when the SS fan starts up and
you might have something though. However, these will only be useful for
laptops (possibly) but not likely for desktops."
