‘There’s a sucker born every minute” -P.T. Barnum

This morning we’ve been having a heated discussion at the Hack a Day offices (read: legion of doom) over Dyson’s new offering, a “bladeless fan”. At first this seemed extremely exciting, but how is the air being moved? We were hoping for a device operating via ionic wind but that’s simply not the case. 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 similar 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?

Enter the P.T. Barnum reference. Known as a man who could sell anything, his legacy lives on in the Dyson corporation. 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.
