Air Multiplier™ technology - how it works

Air is accelerated through an annular aperture and over a 16° airfoil-shaped ramp, generating an uninterrupted stream of smooth air.

Update (July, 2010): the impellor in the base of the Dyson Air Mulitplier(TM) draws air in to the machine. Only 7% of the air generated actually passes through the impeller. 93% of the airflow comes from the patented technology we have developed.

i turned on my fan in my room to see the discomfort but i felt no chops of air slapping me.

I'm a metal fan. And I don't have blades too.

it's kinda like an apple product, it's neat, its expensive, and nowbody needs it, but many want it, other ones speak about waste of money, and people who have one say it's worth every penny...

just like with apple...

is funny cuz there was no talkin in the video ha ha ha

I believe the term multiplier refers to the fact that 93% of the airflow comes from the surrounding environment and was not directly generated by the internal impeller. Whether or not you think their products are expensive or worthwhile, you have to admit that this is an awfully clever application of fluid dynamics. Furthermore, it's a very compact and modular design. I certainly wouldn't buy one, but I think it's a fantastic example of forward thinking.

Ahh Icy. (I See).

Don't like the name it does not multiply the air, just sucks it in and blows it out. And I wonder if it uses a air pump in the bottem rather than a fan, could build more volume

@jadetraveler it uses jet engine technology, check the video here /watch?v=8he8afjQyd8

[jadetraveler]

Even though there aren't any visible blades, I imagine it still has to have blades somewhere. Perhaps there are small fans inside it that bring air in from the apparent air vents at the bottom and blow it out the circular portion at the top?

@Robertsupersnipe18 person who dose not know sicience!

@k1ngm0m0 yeah, that's because the "problem" exists only in Dyson's mind, there is no problem really. Solving non-existent problems with pointless technology, painting it yellow and selling it for a ludicrous price is what Dyson is all about.
