And One Ring Shall Cool Them All: The Dyson Air Multiplier

Looking for a cool way to stay cool? Check out the Dyson Air Multiplier.


Theremin players may be disappointed
by the sound quality of the Dyson

While sitting in a friend’s sweltering apartment the other day, I found myself staring mesmerized by his oscillating fan, wondering if anyone had thought about moving fan technology forward since I first did this at my grandma’s house when I was a toddler. Well, if you’re aware of how much James Dyson’s vacuums suck, you won’t be surprised to learn that his fans blow. I mean literally, because actually, they’re kind of, er, cool. And the 350 scientists and engineers that developed them might be offended at my calling them “fans”; Dyson actually has them trademarked as the Dyson Air Multiplierâ„¢. Although there are no visible blades, an internal motor rotates nine asymmetrically-aligned blades to pull air into the device, and then move it up the pedestal and into the precisely angled ring at the top. Then physics does the rest, through phenomena referred to as inducement and entrainment. It’s the entrainment part that helps eliminate the choppy breeze created by a conventional fan; as the air moves smoothly out of the Air Multiplierâ„¢, the surrounding air begins to move in a stable fashion as well. And this is the device’s main selling point, aside from its unique appearance. Which frankly caused me a little disappointment. Given the design, I at first secretly hoped the thing used some kind of electromagnetic force to move the air. Now THAT would be cool. In any case, the Air Multiplierâ„¢ is getting good reviews, although even Consumer Reports points out that 300 bucks is a lot for a fan. Perhaps if the reviewers had some pressing need to move a balloon around in circles (see video below) they’d be more impressed. My only criticism is kind of silly; how’s a kid supposed to make a robot voice by talking through the fan, or pretend he’s flying an airplane? Oh. Never mind. I guess we that that covered.

The Dyson is also handy if you have a few grand laying around and need to move a balloon around a room in a carefully controlled fashion:

    We were just talking about the wackiness of this yesterday. (While cleaning filthy fans).
