Gotham Gadgets: SAY GOODBYE TO THE BLADE James Dyson introduces the bladeless fan. No blades. No buffeting. Multiply Your Manhattan Degree of Cool With the Outstanding Dyson Air Multiplier Fan! Whom You Know Highly Recommends It.
The hottest thing in Manhattan this summer will make you the coolest!!! Known for their expertise in vacuums, Dyson has created the Dyson Air Multiplier and it is the most genius engineering we have seen in quite some time, and we do test many gadgets. We believe genius is genetic; we have featured Dyson before you'll remember, but not James. This is James Dyson's first entry into Whom You Know. He follows his son Jake! Jake is a Mover and Shaker:

James Dyson, who for the past 30 years has continuously revolutionized the vacuum cleaner industry, has turned his attention to addressing the everyday fan. As a result, he has designed the Dyson Air Multiplier™ fan, which has no blades. Instead, it uses a unique technology to multiply air 15 times, and through unprecedented advancements in airflow engineering, expels 119 gallons of smooth and uninterrupted air every second. This really is difficult to believe until you see it. When you see it, you will just HAVE to have it.
Until today, conventional electric fans have gone largely unchanged. The fundamental problem has remained the same for more than 125 years; the blades chop the air creating an uneven airflow and unpleasant buffeting. Dyson’s fluid dynamics engineers spent four years running hundreds of simulations to precisely measure and optimize the machine’s aperture and airfoil-shaped ramp
before perfecting Dyson’s Air Multiplier technology. Air fluctuations were mapped with Laser Doppler Anemometry, helping measure control the machine’s airflow.
“We realised that this inducement, or amplification, effect could be further enhanced by passing airflow over a ramp,” says Dyson. “And of course this was the point where the idea of a bladeless fan became a real possibility. Here was a way to create turbulent-free air and finally do away with blades.”
How it works: inducement and entrainment
Air is drawn into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil-shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15 times. The result is a constant uninterrupted flow of cooling air. You will be amazed at what big results happen from this relatively small fan. Throw out ever other fan you have ever used! They are just taking up space, and who has that in Manhattan? You all need this Air Mulitiplier instead; trust us.
