Magic fan?
When it comes to the design of fans there hasn’t been much innovation or change for a long time. An electric motor turns some blades which then produces a flow of air. The design is simple, yet effective, and we use such fans in everything from keeping our PC components cool to keeping ourselves cool on a hot summer day.
Dyson, most well known for revolutionizing the vacuum cleaner market with its bagless design, has now started another revolution with fans. Its researchers have managed to create a fan that has no blades yet still manages to produce a strong stream of air flow.
The fan is called the Dyson Air Multiplier and resembles the design of a magnifying glass. In the base is an brushless electric motor which pushes air upwards into the loop where it is amplified 15 times. The air seeps out of the ring and is actually an extension of the AirBlade technology the company developed for its hand dryers a few years ago.
Watch how its works here:
