Re: It has blades: Dyson’s little white lie
#2The author makes a point at the end alluding to a violation of the conservation of energy, By, to be fair, Dyson only says that this fan multiplies to amount of air, not the amount of energy. All fans multiply the air moved (simply by dragging adjacent air along for the ride), so I'm not sure why this claim should be a concern.

#3Fan death is a widely believed superstition in Korea. The idea is that"an electric fan, if left running overnight in a closed room, can cause the death of those inside (by suffocation, poisoning, or hypothermia)." http://en.wikipedia.org/wiki/Fan_death
Something like this could be very successful there, even if there are actually fans in it. Superstition is about appearance and intuition, not reality.

It is not the fans that cause such a supperstition it is suffocation/hypothermia caused by continuous air flow that the superstitious think is the problem.

#5I don't see how it's really hack-a-day material. It's more of a rant, and someone using the wrong site for which to air one's grievances... but it's their site, not mine. And I'm known to rant off-topic a bit in my own little corners of the web, as puny and insignificant as they are.
Still, Dyson is a bit of a snake-oil salesman. He makes sleek, designer houseware and peddles it via the outlets frequented by those with disposable income whom are always looking out for sleek, designer houseware.
An impeller that leverages the venturi effect does not a visionary make. It just means the new, inefficiently-placed blades are going to be almost impossible to clean off once they become gunked up with allergens.
Dyson didn't pioneer vortex separation technology, either. That shit's been around for many decades, and is likely older than I am.

Funnily, people in Austria seem to also believe that fans on at night make people sick. Not dangerously sick. They think it will give them colds.
I believe it about closed air conditioning systems, but not fans.

#7This is a bit harsh. Anyone who has a Dyson Vacuum cleaner understands the amazing attention to detail and build quality, efficiency, etc. Even if it's not a miracle fan (who said it was going to be), having a 'dyson' designed fan will be enough to make it a success. They consistently make fantastic products.

#8It's news that marketeers exagerate to the point of lying in commercials?
All they had to do was say it doesn't have CONVENTIONAL blades. But then 90% of the low IQ market this is aimed at wouldn't know what they mean, so they just left out "conventional".

That's BS. Having recently bought a new Dyson Vacuum cleaner, I'm still surprised just how well thought out, well put together it is. The attachment that uses the suction to spin round a brush for cleaning stairs/cars is impressive enough - the roller brush spins fast, but it still sucks up everything. Let alone all the other unique features. There simply isn't another manufacturer close (Even though they try to copy every feature).
Just because something also looks beautiful, don't assume that's the only reason it's successful. (Also see Apple).

There are a lot of different reasons for this, including the fan blades chopping the oxygen molecules in half.
My cousin had a roommate in South Korea who believed that the fan would create a vortex that sucked the air from the room, creating a fatal vacuum.
