Cutting edge innovation is synonymous with Dyson products, and this fan is no exception. 

As Bit Rebels defines it here (http://bit.ly/aLV1hx), 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. With no blades or grille, it’s safe, easy to clean and doesn’t cause unpleasant buffeting.  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.
