Dyson launches the bladeless electric fan

First there was the bagless vacuum cleaner, then the towel-less hand dryer: Now James Dyson, the British inventor, has developed a bladeless electric fan which goes on sale on Tuesday in the US and Australia.

The Dyson Air Multiplier fan – which looks like something straight out of a sci-fi movie – uses advancements in airflow engineering instead of traditional blades to ‘multiply’ air 15 times and push out 119 gallons of smooth and uninterrupted air every second.

“It will be available in two sizes, a 10-inch model costing $300 and a 12-inch model costing $330.”

They’re REALLY proud of their products.

What about the beltless trenchcoat?

[Doogle]

*LOL*

velcro

[arthurus]

Is this thing “bladeless” or are the blades merely internal?
How does it “draw air into” it?

“The new fan works by drawing air into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil-shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15 times. The result is a constant uninterrupted flow of cooling air.”

The question I have to ask is what is drawing the air into the base of the machine? Could it be a “rotary blade”?
I can't wait to be the first in line for a $300.00 fan so I don't have to be subjected to that pesky “turbulence”.

How? “Drawing”. “Forcing”. “Accelerating”. All without a fan or turbine in sight — not even hidden in the base of the machine. Shyeah, right. I don’t believe it.

Pistons, maybe? Something has got to create a vacuum else no air ain’t moving nowhere.

[Recon Dad]

I’m starting to think the quote, “Build a better mouse trap and the world will beat a path to your door” might not apply in this case.

At these prices I can move air for quite a bit less.

[listenhillary]

Cat hair sucked into the base and propelled at you. Cool!

[Doogle]

...would imagine, if ya plug it in,it has to have moving parts...*smiles*

[Doogle]

*LMAO*

[Boiling point]

Wait till they see my hoseless air tools!

[DieHard the Hunter]

>> Pistons, maybe? Something has got to create a vacuum else no air ain’t moving nowhere.

Convection perhaps? Heat the air inside, make it move and draw in cool air from outside? No moving parts involved with that, granted, but it’s difficult to imagine that being able to create any significant airflows.

[wolfcreek]

My oldest daughter and SIL dropped a cool $530 for the *Animal* vac about 3 years ago.

That price “sucks”.

[uglybiker]

Yeah. for just a few bucks, I can whip up a whole mess of chipotle cheese and bean burritos! :-D

[Renkluaf]

OK, so I want to pay $300 for an electric fan because...?

[Hacklehead]

Does it also let you travel to other worlds?

[taildragger]

I need to see a picture of the slot, could this be an application of the "Coanda Effect"?

Dyson wants you too.......and your parakeet can fly through it like a toy helicopter

Send one to the White House for the dickless POTUS.

[CPOSharky]

I have a looks-like-new 12-inch fan that cost $1.00 at a yard sale and is stll working fine after three years.

[shove_it]

“...push out 119 gallons of smooth and uninterrupted air every second.”

I wonder how you measure a gallon of air?

I do recall our mess sergeant sending a noobie KP out on a mission to his counterpart in Charley Company for a bucket of steam. That was in the Army a long time ago

[Doogle]

I watch a guy run off to get a few hundred feet of flight line....

[SoothingDave]

The same way you measure a gallon of anything else. 231 cubic inches. Air movement is normally measured in cubic feet per minute, but one could easily convert this to gallons if one wished.

[SoothingDave]

Gallons per second, that is.

Last I saw, the Chinese-made fans at Wal-mart were less than $10.00.

At $300.00, Dyson is probably trying to recoup start-up costs like R&D and creating the manufacturing dies and production machinery. Also, he probably started manufacturing (at least the prototypes) in Britain, where everything is more expensive. In 2002, a US$35,000 Jeep Grand Cherokee Limited buit in Graz, Austria, sold for 35,000 British Pounds in the UK.

[doodad]

Ours was send the noob to the tool rental for a sky hook.

[Yo-Yo]

I think more appropriate in this case would be a bucket of prop wash.

[cuz_it_aint_their_money]

If this thing is anything like his vacuum cleaner, we'll pass.

The wife says, his vacuum cleaner is the biggest waste of money she has ever seen.
Quote - I don't care what his ads say, his vacuum cleaner looses suction after a couple passes over the carpet! - Unquote.

[Pharmboy]

Didj’ever use one of those air blade hand dryers in a bathroom? They work, but it sounds like you’re on a runway and an Airbus 300 is landing 10 feet from you.

[Adams]

Funny you should mention that; I have a few cases of those in my garage. Interested?

[ErnBatavia]

What I'd like is a dust collector that really works. I've tried things similar to the Oreck and they're pretty bogus.

Our TV and computer are in a little retreat off the bedroom, and this area attracts dust like nobody's bidniss, I assume due to the electronics.

[Doogle]

...waiting for the youtube vid of some kid in school with bubble blowing liquid to “experiment” with this device

[Doogle]

exactly

[battlecry]

That’s probably because it ripped your carpet apart and is choking on the fibers.

My wife called me at work after she got one of those darned machines to tell me how much dirt they catch. I came home to find the hard ultra fast spinning brushes were tearing her rugs and carpets to pieces. The dirt she thought she picked up were the remains of her rugs.

Avoid them if you care about your carpet.

[listenhillary]

The Oreck air machine just makes the dust stick to every surface.

You might try a Roomba that runs through the area daily and a free standing HEPA air filter. Both are pretty noisy. If it is away from your sleeping area, you might be able to run them at night.

[Pharmboy]

Well, I guess we’ll see one now...HA!

[Joe 6-pack]

Or the strapless bra!

[Blogatron]

What happens when sh*t hits it?

[listenhillary]

I’m sure it would take an efficiency hit. The air flow disruption could be tremendous. There really isn’t enough push to propel the sh*t, so I doubt it would go very far or even make it through the fan.

The bladed fan is entirely capable of far flung poo.

[shove_it]

OK Dave, fill 'er up and don't spill any.

[USS Alaska]

I wonder how you measure a gallon of air?

Use a three gallon bucket and only fill it one third of the way.

[shove_it]

You must be a math major. BTW, your bucket is nicer than mine.

[buck61]

What I’d like is a dust collector that really works.

I got it for you, and it’s cheap.

Go to your local hardware and buy an air cleaner for your furnace, or heat pump. Get a 12” fan, cut the air cleaner to fit the back of your fan. Apply Pam to the air cleaner, helps collect the dust, wal-eye!!!!! there you have it.
I use this in my computer room, (desk top) to control dust.

[SoothingDave]

It fills automatically. Nature abhors a vacuum, remember?
