I thought it was going to be a magnetohydrodynamic drive, not a glorified fan with a baffle.

Indeed, it has blades, I think their point is that most of the air is moved through the "air multiplier" rather than directly by the blades.
It sounds like they're trying to get some hype, I'm not sure justified one.
They're offering the 25cm model for $300 and the 30cm one for $330.

As to moving air without blades, I'm wondering whether a [url=http://en.wikipedia.org/wiki/Tesla_turbine]Tesla pump[/url] can be easily used for gas (as it is for liquids).

After eating lots of onions, I can do that trick too !

I read an early review that not only does this fan have blades (housed within the stand) but the motor is rather more noisy than that of a conventional desk fan and emits a noise akin to..... a vacuum cleaner! It implies that this is simply an alternative outlet for Dyson's air movement hardware (which is, in effect, all a vacuum cleaner is). Note that their only recent innovation that didn't move air (the washing machine with a contra-rotating drum) is no longer available, leaving us with some funky (and, I'll admit, very useable) vacuum cleaners, the Airblade hand drier and this new "air multiplier".

I read about that in the newspaper this morning and they had a picture. It's a very cool looking device.

I have decided I want one. :)

I have a Dyson vac. It works OK and was pretty expensive (about $600).

Where the vac appeared to be innovative and its uses seemed intuitive, this bladeless fan idea seems more like an invention in search of a product in search of a market.

I wish him luck.

Powered by a perpetual motion machine, no doubt :roll:[/quote]

:D!!! It probably will work because Dyson vacuum cleaners are very good and many of my friends use them so if he says it works then it probably does.
