liquid cooling is great and all, but if you're building a cheap HTPC, it may be out of budget.
This is saying cheap, quiet, efficient. I like the idea of it. Makes sense if you want something quiet that performs well.

Performs well, Unless you get dust.. Im in Iraq right now... This would never work here and I know common folk refuse to dust their PC's... it will spell disaster!!
Very very old news. First time I heard of the ionized air fan idea was in an Elektor electronics magazine back in 1982 or 1983 where they presented it as a diy description, maybe someone can dig up which back issue it was in. The inherent problem is of course that ionizing air generates ozon which is toxic.
the smallest statice electric spark is around 500 volts,,,3000 is really nothing if there is minimal amount of power flowing through it,,,the only way to get a good shock off the system is if you touch both ends at the same time,, then you're just being an idiot
as for making heatsink bigger,,this is for a laptop, ppl are trying to make them smaller, not heavier
I agree the ozone part may be an issue,,but who knows how much is actually generated, it may take days in a completely sealed room to have enough to cause a problem.
uses less power than a fan, even after the conversion of 3000V in a laptop? I'd like to see this!
Surely there are safety issues with 3000V being on a device like a laptop; risk of getting electrocuted, risk of distorting radiofrequencies like wireless lan, cellphone signals, the internal sound card, interferring with hearing devices (or perhaps pacemakers)...
It's pretty hard to imagine, looking at my laptop, that this device will be able to extend more heat than a fan, seeing that my laptop's fan is pretty powerful and needs a lot of air to cool it.
So perhaps the system used needs a larger surface? It's hard to imagine it could extract more heat from a laptop than a fan would, while not being able to provide the same airflow.
What would happen if an obstacle would be next to the laptop (eg: an empty plastic bottle placed next to the fan's exhaust)? With less airflow, and still more heat being extracted, the bottle could locally heat up a lot, and perhaps even melt.
Hard to believe... Especially if they say that it 'costs less than a fan'. Since a laptop fan costs less than $1, it is hard to believe those claims are true!

ponder 30-50 ionic coooled laptops on a 4hour plane ride...
Wow, what a great idea, except for the fact that electrical discharges like that create Ozone. Now you can only use that laptop with the new ionic wind cooling system in a well-ventilated area. And the idea of adding a prefilter that they proposed? Wow, apparently these people have never worked on a laptop before. Filters on laptops are in general a really bad idea. The average user never cleans out their laptop fans with with compressed air, and adding a filter would just exagerate the problem becuase it would trap more dirt and I cant even count the number of laptops that have come into my shop because theyre randomly turning off or rebooting, just to discover the heatsink completely entombed in a crust of dust and fuzz. Youre best bet is just to pass small dust straight thru the heatsink and blow it back out like most of them already do. But of course with an electrostatic charge being used to move the air, I can only imagine how that would turn out. Stick to the $1 brushless DC fan in my opinion.
don't comment on power converters unless you know how they work... voltage doubling effects from a DC standpoint work by manipulating charge on a capacitor. there is no way for this voltage to supply any amount of steady state current whatsoever, so in the event that the charge is rapidly removed, the event would be similar to an ESD event. so the power supply which generates 6 kV only needs to keep up with the leakage current(generally small, microamps worst case)
oh and P = I*V is in watts, which is in joules / sec, so 1,000,000 V of potential discharging with 1 microamp (average) over 1 sec is 1 W of power during that 1 sec, and 1 J of energy is discharged.
as others have said, the problem with ionizing air is the ozone it produces
