whoa, very nice!, i wonder how high they can build the pressure upto. id like to see if they can produce an electric version of the turboprop lol

read about this the other day, very cool

just wondering how much power it uses

How much power & how much it will cost. Not really worth it if it's $50.

How much will dust effect it? Can it be scaled up/down, Does it prduce EMFs?

Other then that its a great ideal.

i looked into this, the way it works is that tiny thin wires are electrified, then about 50mm away are curved wires representing the positive portion of the circuit as the voltage goes higher the air is ionized by the negative wires and travels toward the positive. in order to produce high air flow the voltage has to be high as well. these solid state fans will shock you if u touch them, arc electricity of damaged and may cause fire in hazardous environments.

And like ionizing filters, dust would cause them to arc, so you would want case filters which is a good thing anyway. You could also design the cooler to be inside it's own filter.

Yeah, filters. Probably some sort of cover would be implimented for protection. I'd just like to have them in power supplies (where there is already the option to do high voltage without adding bricks & such). Other than my hard drives, it's my power supply that I can't seem to quiet down (well, without worrying that it'll self destruct).

Zallman.

Interesting and I hope it becomes an affordable reality but filters, especially on PCs are often ignored. A dirty PC filter then causes more heat.
