New electric fan, without blades

[SagaLore]

This method of airflow could be used for a new type of air flight. :Q

I'm going to put this right next to my Ionic Breeze® air purifier and fire up my Bose®
stereo, life doesn't get any better.

 

[jonks]

I think it's pretty clear, the fan will not take off

You know what they say - "no highs, no lows, must be Bose."

that is awesome

Now the question becomes, if we point it at a treadmill, will it take off?

All Dyson's done is repackage an air amplifier into a small package. And air amplifiers have been around for a long time.....so nothing's been "invented," just a design has been adapted for home use instead of industrial use, where air amplifiers have been used for years and years.

How air amplifiers work, courtesy of Exair whose design Dyson apparently copied.

2009 .... Dyson "invents" overpriced impeller fan
???? ..... Miles Dyson "invents" neural net processor

The time is near!!!!!

 

[Kanalua]

should just buy this fan instead: http://www.amazon.com/Lasko-49...qid=1255563461&sr=8-27

type it in to google.

CFM is a more standard measure, and you can compare it to your computer fans.

$300 for the 10-inch model, $330 for the 12-inch

That's what... he said?

It is the shady PR department trying to pull a fast one on the uneducated consumers.

Normally fan out put is measure in cubic foot per minute (1 CFM = 7.48 GPM), therefor 119/7.48 = 15.9 CFM. IMHO, you are going to find quieter, higher efficient, and more powerful fan for less money.

Math fail. 1140ish CFM.

That's actually really badass. :Q

Type it in to google. Or try my link about 4 posts above this one.

Cutaway view so you can see what is inside the base
http://stuff.tv/blogs/cool/arc...m10-bladeless-fan.aspx

It looks like a two stage impeller in the bottom. Lower to bring in air in volume and upper to push it into a higher pressure stream.

I'm curious about the speed and the size of the impeller . I think some are thinking this is just an impeller sucking in air and blowing it out the ring, but that isn't what they are doing. They are using the smaller amount of air taken in at the impeller to lower the air pressure around and slightly in front of the ring, causing the air that is left in the center to move forward , you could get much more air moving through the ring than you put into it from the impeller. It is very close to how wind works in weather. A normal fan pushes the air with the blade this is lowering the pressure and letting the higher pressure in the room move the air.


Watching the video it outputs 15 X the air that it takes in at the impeller, so it could be extremely quiet and still provide a lot of air.

I'd imagine that conservation of energy still applies. With a hidden impeller, and the fact that the air-flow is indirect, I think it'd actually take more energy than a regular fan for moving the same amount of air. It's probably less efficient, and thereby louder, because it's still using a fan. If they could create the same amount of airflow using some type pump, it could be quieter. This is just me speculating. The fact that it's hidden will reduce noise somewhat, but it can't be by that much imo.

It is really hard to tell from the videos . the interesting thing is that from the cutaway it looks almost exactly like the engines that I saw on fighters when I was in the navy in the early 90's.

I wonder what would happen if you fed the intake of the fan with some propane and struck a match

Airconditioners can be had for less than what Dyson want for them fans.

 

[IronWing]

Dyson is a marketing genius but I'm a real rocket surgeon! Take this piece of hype and install a liquid feed system into the ring and you could have humongous, giant, bigger than the city of Pittsburgh, soap bubbles!!!!!

 

[spidey07]

You guys sure are helping fuel demand for this awesome product! Welcome to the future of fans...experience the pleasure...welcome to Dyson.

 

[StageLeft]

Not impressed.As mentioned, it still has blades, they are just in the base. It's simply a fan with a small high rpm motor and then this ring to redirect the air.

 

[Engineer]

Industrial air amplifiers have been around for decades. He simply made it bigger. Vortex brand air amplifiers are used throughout industry to get a large air flow from lower volumes of compress air. Not new...but bigger in Dyson's case.

Examples

It plays Music? Will there be an English version?

I agree with the majority of comments, interesting twist on known technology, but the price is way out of whack for what minor improvements it would provide over current tech.

It has blades. It is also far from quiet.

It's a genius design, though. Really cool.

It's not even remotely close to a new idea though, he just applied eighty year old tech to a fan!

It's just a modified NACA cowling: http://en.wikipedia.org/wiki/NACA_cowling
