Fan, without fan?

Have you ever see a fan without fan? Wonder how?
Introducing Dyson Air Multiplier™.
The Dyson Air Multiplier™ fan works very differently to conventional fans. It uses Air Multiplier™ technology to draw in air and amplify it 15 times, producing an uninterrupted stream of smooth air. With no blades or grill, it’s safe, easy to clean and doesn’t cause unpleasant buffeting.
How it works
Air is accelerated through an annular aperture. This creates a jet of air that passes over a 16° airfoil-shaped ramp, channeling its direction.
Using an airfoil-shaped ramp (like a cross-section through an airplane wing), airflow is amplified 15 times. This creates a smooth, powerful airflow, with no need for fast-spinning blades.
