To put it bluntly, the Dyson Air Multiplier Fan should not work. It's a ring around a gaping hole. Yet, every publication that reviewed it says it performs as advertised and they have no idea how it does either.
What the heck is the Dyson Fan? It's James Dyson's (yes, the guy who updated the vacuum cleaner and the hand dryer in the same awesome manner) take on the electric fan, removing the blade and leaving nothing but a ring and a base.
Looking more like a giant Fruit Loop than a home appliance, the clever fan manages its wind-blowing ability using some clever engineering tricks. According to the press release, the fan draws air from the base of the machine, forces it up into the loop amplifier and accelerates it through an annular aperture, creating a jet of air in the large loop-the loop. Then, this jet of air pulls more air from behind the fan into the airflow, along with the surrounding air around the device, eventually amplifying the resulting stream as much as 15 times.
Did you get that? I honestly didn't. But it sounds clever, right?
Simply put, they successfully created a bladeless fan that actually blows air, spewing 118 gallons of it every minute. Since, there are no blades, there's no chance of anyone hurting their fingers there, too. Even better, it looks spanking hot and operates quietly. How can you resist?
Well, I'll tell you how. The Dyson Air Multiplier Fan is scheduled for release this fall at an innovation-worthy price of between $300 to $330. Yep, that's how you can resist.
