seems like theyre getting more and more mainstream now, would be awesome... totally silent
as in Dyson bladeless fans?
thought they still had blades but hidden in the base?
no idea =\ thought bladeless fans in general were just em fields.
you still need a mechanical force to move the air.
wonders how well it works in dusty environments?
If the price of the Dyson fans is anything to go by, they'd be upwards of $50 each. No thanks!
Give it a few years and not only will they probably be available, but I'm sure the price would be potentially better too. I'm guessing at the moment Dyson have an exclusive patent?
I'd pay $50 for something like that
Theoretically you could ionise the air and use electromagnetism to cause it to flow.
It would be stupidly inefficient, but it would work.
EDIT: it has been done. http://en.wikipedia.org/wiki/Ionocraft
There's still a motor in them, so you might not get the propeller noise, but you'll still get the sound of the motor revving..
Cool idea though
As would I.
how would something like this perform infront of a heatsink or radiator. basically what would be the static pressure?
One assumes bugger all
those dyson bladeless fan's aren't half as quiet as you might think they are...
its not really that amazing, you could use the technology they use to "pull" more air in with just a normal fan. I saw it on that richard hammond engineering show when they were showing how to inflate a huge plane life raft in a few seconds.
i cant find the video at the moment, but they showed with a rocket tied down and and a funnel, the funnel caused 4 times as much air to inflate the raft.
[pip]I would pay fifty dollars for one[/pip]
Apart from the novelty factor the dyson bladeless fans offer nothing. The move less air then a conventional fan and make 3x the noise.
This man is on the money. I'd pay to NOT have one of those fans anywhere near me. Would make your pc sound like a rackmount server
There was a story released about silent ion based heatsinks for notebooks that came out a while ago. Be damned if I can find it now though, googling for anything with 'ion' in it brings up page after page ion based cpu/mobo's.
they do make it harder for your 2yo to stick pencils into a moving blade.
It's called parenting.. The electric fan has been around since 1886 and yet the human race continues.
I'm still not seeing the motivation to pay $400 for a loud and inefficient pedestal fan.
now you're wandering off track. You said it doesn't do anything, I said it can. You can say the same about seatbelts; if you never let a child near a car, seatbelts don't contribute anything to their safety.
I'm making no judgements about letting a kid near a fan, only what the fan design means if you do.
