Air Multiplier technology, fascinating and intriguing

I thought id make this thread to share with you what ive found, this product is made by Dyson, you may know them for making vacuum cleaners, They also make fans ,heaters and hair dryers.

This technology to me is simple, yet very effective.

Here is a video on how this technology is used:



And here is a video show the effectiveness and control this device has:



Intriguing isnt it

How it works

So to sum this up, although this is a simple technology, has this technology been used before? ( before it was Trade Marked by Dyson) , and can this technology be used on a much larger scale for purposes that may be discussed here?

Thoughts....

And yes, they are pricey, but remember, its the concept i wish to discuss.

Both videos are very good.

I don't know, but I have a feeling it's related to Hovercrafts and possibly some types of aircraft - such as Harrier jump jets.

Now that I'm looking around a little online, seems like it's related to "Thrust Vectoring"

I think those "bladeless fans" are really cool, but still way too expensive.

It is neat, but its not really making more air pressure/speed then what the fan in the base can provide. Sure its kid safe and quieter, but since the fan is in the base, it might gather and hold more dust (harder to clean). Those things are also SUPER expensive!

I do agree on the price of these things are inflated, but its the concept that i think is (cool)

The Bernoulli and Coandă effects explain this fully.

"Air Multiplier Technology" is a marketing term trademarked by Dyson.

reply to post by chr0naut


I know its a Trademark

And for everyone else who had no idea what the Coanda-Bernoulli effect is:

I saw this at the store recently, the air stream seemed stronger than most fans, and the ones with heaters in them were great.

What could this tech be used for?

How about a giant one with a person and a parachute standing in front of it.

Connect all those circles in the second video together and you got a tube transportation device!

Simply the old "ducted fan" principle with the fan aspect removed from the ducting side of it.
Probably a great lost of efficiency in the ducting.

300$ for a fan. They are completely crazy,
they can keep it. True breakthough is when it's affordable.

Thanks for all your replies guys, but since we cant even discuss the potential for this technology as requested in the OP, it seems you'd all rather harp on about price, there is a tonne of crap most of us can not afford, get over it.......

Over and out!

Buy one, take it apart, put it together piece by piece, learn how to make one of your own, figure out a cheap way to do it and sell it yourself!

It's a possibility.

It will be dirt cheap soon.

Remember the pedestal Ion Air Purifier by Sharper image? They used to cost a ton back in the late 90's, now I can go get a $10 one for my car. They don't really work, but this is just an example.

Simple.

Power comes at a price.
Air circulation created by machines requires mechanism to move it around.
Mechanism requires Power to produce the air circulation.
Air consists of dust particles so naturally the fans will accumulate dust.
Pain in the butt to clean? Possibly.

Either way one has to pay for the electricity (unless using paid solar panels or paid personal wind power generators).

Only advantage is the safety factor for those who have toddlers.
The rest is cosmetics and buzz words used just to rip off the consumer.

Thats the way I see it

Stretch this over a horizontal airfoil to increase lift?
It looks like it might...this ould reduce fuel consumption and maye allow slower speeds or even VTOL?
The concept would definately work......turn a momoplane into a bi plane instantly...allowing way greater manouverability because of reduced wing areas....wooooo woooo!

Aircraft have been attempted utilizing the same effect.
Avrocar

and RC model / UAV:


And plans to build your own RC version:

That is a cool RC, we have something very similar to that here at home. Im not sure if its the same principle as the Air Multiplier effect though. Looks more like a powered blade fan with the blades angled down.

Cool Vid

S&F! This is a great and innovative way to think of fans. 15x more power. Imagine as the technology develops. We can be driving airfancars or hoverccles in a couple decades. Eventually we'll have Futurama's airtube transport system.


(sorry, I cannot figure out how to embed a YouTube video. I entered "F2wBGzCzv_E" as the video number. But the link says, "F2wBGzCzv_E\". Not sure where the "\" is coming from. Here is a link...)

YouTube : Futurama Opening

Awesome indeed!

From what I know about technology this is an awesome piece of equipment.

I am in agreement with most posters about the price being exorbitant.

Being a tinkerer and project person I can see many applications for the use.

Hovercraft for one or two, wind machine for a small movie company, as well as ventilation systems.

Like for bunkers and or any other hidden locations.
