Latest Invention: Blade-free Desktop Fan from Dyson

Share

The latest invention of the popular inventor James Dyson is a desktop fan that is safe for children. His fan, dubbed Air Multiplier, does not have visible blades with the key feature being a hollow plastic hoop that has an aerofoil cross section.

The fan stands vertically on a pedestal. Dyson's latest invention takes advantage of a new type of airflow engineering in order to drive air up via an energy-efficient brushless motorbase. The air is then multiplied 15 times and driven out through the hoop's airfoil surface at a rate of 118 gallons a second.

According to Dyson, the company, the fluid dynamics specialists needed 4 years in order to run "hundreds of simulations to precisely measure and optimize the machine's aperture and airfoil-shaped ramp." Engineers managed to map air fluctuations using the so-called Laser Doppler Annometry.

It is worth mentioning that at lower speeds Dyson's latest invention is rather silent. It comes in two versions: the 10-inch model, which will be available for $299.99 and the 12-inch model, for $329.99.
