Dyson's Bladeless Fan Isn't

From Hack A Day (cool site):

"This morning we’ve been having a heated discussion ... over Dyson's new offering, a “bladeless fan.” At first this seemed extremely exciting, but how is the air being moved? ... Some of us think the bladeless claim is an outright lie, others understand it from a marketing stance, but we all agree: a fan with blades is still moving the air.

"Dyson's own information page states that “an energy efficient brushless motor” draws the air in with ... technology used in “superchargers and jet engines,” both of which use blades! The fan blades are in the base of this unit, they take in air and blow it out the ring. Just because you can’t see a fan, can we call our computers bladeless, or an air conditioner bladeless?

"At 200 british pounds (~$320) for a ten-inch desk fan, what are you getting that’s better than a traditional fan?  The design supposedly amplifies the air movement fifteen times, but we’re skeptical about that figure as there’s no energy-saving claim to go along with such an incredible power boost. One thing is certain, you will NOT get a fan without blades for your sterling… just one with hidden blades plus a huge marketing campaign."
