    cool!!!!

    but I'm trying to figure something out;

    what the hell does "accelerated" mean?

    from what I'm reading, there are blades they are just somewhere else, the air is then driven through a compressor of some sort so the air is regulated when released to not pulse

    this looks incredibly inefficient to me if my extrapolation is correct

    [edit]

    futher exploration, it seems my extrapolation is spot on;

    "drawn in" means pumped somehow and turbo chargers do have blades, so do jet engines

    they go on;

    nothing is produced from nothing, air isn't "amplified" from whole cloth, that has to be using energy or losing velocity or suffer some other loss to be physically possible

    [edit] further reading;

    so obviously there is a fan and as I suspected, they simply hide the fan, compress the air and then let it go

    seems to me this is going to use quite a bit more energy for the same amount of air

    anyway, still looks kewl

    If it's a fan then why, when watching the reactions video, are the people's hair or clothing not moving at all?

    the only wind I see so far is the hot air from the people trying to sell it ;)

    I explained it perfectly when I exptrapolated even before I read their tortured explanation;

    it hides the fan in the base, the fan is in the form of a turbo with fins rather then a blade with fins like most

    it collects the air in something close to a compressor, it releases the collected and compressed air over a foil to distribute the air in a particular fasion, and there is no pulsing of the breeze created by this fan with fins (it is not a finless fan)

    simple stuff but it does look cool

    who cares its a bloody vacuum - as long as it collects the dirt from the floor who cares how it does it :p

    well... i guess technically it COULD be a vacuum... although it seems to be more of a desk/window fan than a floor fan. lol

    perris: the only reason they're advertising it as a bladeless fan is because the part where the breeze comes from has no blades whatsoever. yes, it still has parts to move air... but they aren't exposed, and aren't directly blowing the air in the direction you want it to go.

    Neat concept.... but i don't think i'd buy one. They do have killer vacuums though..... and hand driers.

    Well actually according to the NewScientist Webpage's animation describing this fan.. Hole on a stick aims to reinvent the desktop fan - tech - 13 October 2009 - New Scientist ....it actually does not use any more energy than a normal fan of comparable ability.......I will certainly agree....it is overpriced though! LOL!!!! Actualy quite a bit of it is fairly clever....the internal aerofoil shape.....which lowers the pressure, and speeds up the air into a jet.....which then goes out of the ring...lowering the pressure in the center of the ring.....causing it to to literally suck more air through it. Nothing really Sci-Fi about it.....just a novel way of doing an old trick.....other than the fact that the air is less 'chopped up' and more even.....I dont see much of an advantage other than safety......(but honestly....unless you are talking about a HUGE metal bladed industrial fan.......how dangerous are fans really? LOL!!) Ive actually stuck my hand in a fan blade by accident plenty of times......(I have some strange complusion to take the sheild grating off the front of em so the blades are exposed....I guess I imagine more air will get through......LOL) Ive never even had my skin broken by one before......It can sting...but thats about it really. I suppose if you have a pet who is likely to stick their head straight into an exposed one.....then perhaps they could lose an eye or something......Or maybe if you had a really tiny.....thin skinned animal.....like a slamander.....and you dropped it into a fan....well that could be pretty disastorious.......I dunno....I guess Im kinda stretching trying to find a legitimate safety issue with normal everyday house fans......LOL! Youre probably pretty safe unless you have a really stupid dog.....or you happen to enjoy juggling your pet salamanders over the top of exposed fan blades. I dont think I could ever come up with a legitimate reason why I should need to spend 300 dollars on a fan...no matter how cool it was.....Unless I was gonna use it in some kinda science exhibit or something......I will gladly take it off of someones hands though...if they chose to give me one! LOL!!! Actually the design seems simple enough....it would probably make a pretty cool DIY type of project....It would likely not be as efficient as the professionaly made one (assuming that they really did all the research they claim to get the angles and such all perfect)...but to make one that just plain works....should be as simple as rigging up a device that blows air through a ring with a slit in it....a simple aerofoil shape should be easy enough to come up with for the interior of the ring. a hollow ring with a simple curved piece placed around the inside leading to the slit. Any kind of smooth surface that is easily workable, and can be glued airtight together when you are finished would work fine I would imagine. I woulnt mind trying to build this myself!
