Air multiplier

This garbage is called Dyson's Air Multiplier and it is a fan. But the blades of this fan are missing.
The company Dyson , which mainly produces vacuum cleaners, completed it. Therefore, they also decided to build a fan with a vacuum cleaner, and why not in fact.

As a result, of course, the blades are there, but they are located at the base of this fan, and the injected air is directed through the gap in the plastic ring in the right direction. The air flow is not intermittent, like a fan, and uniform, like a vacuum cleaner. Well, the fingers in the blades can not sunesh - also good for those who have children at home.

From the dark side of the force stands the price of $ 300 for a 25-centimeter fan, as well as the fact that it is buzzing like the aforementioned vacuum cleaner. Yes, and the air flow is obtained weaker than from a fan of the same size. For some, it will be critical that now it will not be possible to mow under the voice of Darth Vader by talking through rotating blades.
