Dyson's air multiplier can replace those old and noisy blade fans.

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. The Air Multiplier is the first ever fan without rotating blades, instead, it uses a combination of basic physics and cutting edge aerodynamics. Air is accelerated through an annular aperture. This creates a jet of air that passes over a 16° airfoil-shaped ramp, channeling its direction. No blades means the Dyson Air Multiplier™ fan is safe and easy to clean. It also has touch-tilt, 90° oscillation and dimmer-switch power control. But not all things about this air multiplier are good. This Air Multiplier will sell at £199 through high-end retailers, making it reachable only to the high level users who really need the cooling power of the fan.
