    I found an interesting article:

    "Say goodbye to the blade. No blades. No buffeting.

    Chop, chop. The blades on conventional electric fans literally chop the air, which means the airflow is uneven, causing unpleasant buffeting.

    The Dyson Air Multiplier™ fan has no blades. Instead it uses Air Multiplier™ technology to amplify air 15 times, expelling 405 litres of cool, smooth and uninterrupted air every second.

    Air is accelerated through an annular aperture set within the loop amplifier. This creates a jet of air which passes over an airfoil-shaped ramp that channels its direction. Surrounding air is drawn into the airflow (this is called inducement and entrainment).

    Dyson’s fluid dynamics engineers ran hundreds of simulations to measure and map airflow – allowing them to precisely optimise how the Dyson Air Multiplier™ fan works.

    The Dyson Air Multiplier™ fan is powered by an efficient brushless motor and air speed can be precisely adjusted with dimmer-switch control. Fans with blades are only wired to run at just two or three settings.

    No blades means no need for a grille; so it’s simple to and safe to clean.

    And because its motor is at its base, the Dyson Air Multiplier™ fan can be tilted with a touch, unlike a conventional top-heavy fan, which needs to be positioned with two hands and can topple easily."

    Solid state fans are a great technology but they lack the 'street credibility' in real applications.

    Dyson has invented great air fans for purposes like hand dryers in rest rooms. Remember Green is in this year.

    Link to Video as it helps understand a bit better:

    Not to mention he makes excellent vacuums, so he knows about all things that suck. :laugh:

    :laugh: Good pun. But for ~$314USD, I don't think so.
    I think it would be a sweet idea to make them for the pc though.

    Holy sh*t $300 for a 10" fan is redunkulus. PASS!

    Yeah, but he's probably selling them to the same folks who are shelling out 3-400 dollars for 64GB hard drives. :laugh:

    Eventually the prices will lower.

    these will be so cool in pcs though XD

    Dyson stuff is overall amazing, yes expensive, but out of the 10+ vacuum cleaners my parents have owned, the dyson is by far the best.

    Just read the comments on the legit reviews site.

    Someone said something that caught my eye.

    If dyson was a clever man, which he is, he could adapt this for variation of the jet engine.

    Except no blades, so no bird related incidents!

    you see the circular base, theres a fan in there, so its not bladeless

    true, but the blade isnt exposed. That appears to be their main argument - that and the smooth airflow (which would work well for cooling a PC, imagine one of these as an intake ;)

    It couldn't have a fan in the base, as a fan that small could not shift that much air.

    405 litres per minute.

    it has a motor of some kind, and some way to suck air in. perhaps a turbine, or a magical wand?

    Aye a motor, but certainly not a fan.

    Other wise all the crap about fans creating choppy airflow is you know, pointless?

    It be disappointing if it was a fan.

    maybe it's similar to caterpillar and/or magneto-hydrodynamic drives in submarines. "dimmer switch control" so me suggests that the motor is simply uses a variable speed drive, nothing too special there, albeit uncommon & expensive electronics for consumer level stuff.

    price aside (the cost is no surprise), looks pretty effing badass to me.

    Watching the video... if the fan was on it wasn't powerful enough to even move the people's hair at all... or their shirts....

    They should be cheaper now lol.. didn't they move there manufacturing to Europe ?. Or was that just the vacuum cleaners ?.

    And what are the power requirements for this ?.

    sounds like the sharper image kinda thing we have one here no fans and it pushes air but no were near enough.

    that erratic movement may well be caused by the turbulence in a regular fan. If this device is moving a flat, static amount of air over the entire area, it would "push back" evenly and therefore there would be minimal movement.


    think of it as rain vs a river (or a body of flowing water) - rain is easier to see than a flowing puddle of water, due to its erratic, sudden impacts - whereas the flowing water can move slower (and less visibly), but still move more water overall

    Uhm that's been around for sometime

    It's an air Ionizer, Not such a good idea to have Negatively Ionized air around sensitive electronics, it increases the likely hood of Static discharge, but it's still really neat

    Dyson strikes again!

    They are one of those companies that just pours money into R&D.
    They have done a lot over the years and always make a good product.

    Yes for now it's very expensive and quite silly but other versions will be drawn off of it and things will become more popular and readily available through time which is when it will start to take over, some things really never do but lead to other designs.

    R&D is all future planning on the business side of things, and a lot of times its even a money hole but keeps your name up and keeps you on the leading edge..

    That's a pretty cool fan, I feel the urge to find out more specifics on how it works.

    Yeah at the moment the price just dosn't make it sensible for the PC.

    And reading this just makes me think of farting ..:roll:

    Well, I'm not a fan... I'd rather upgrade to water cooling at that price.

    Um.... no actually read how it works lol.

    The ring shape is to create a field of negative air pressure which sucks the air through it.... i'm quite surprised that they took this long to come up with something like this; the concept is simple and used in engineering already; F1 cars especially already doing that to force air at higher pressures into important areas like the radiator , but nonetheless amazing.

    I reckon they'd need to add something like fins to the edges of that ring to clean up the airflow a bit.

    EDIT: If it wasnt for the ABS construction this thing could cost WAY less, but you'd get the problem of the fan imploding :laugh:.
