Dyson Air Multiplier Fan

This sleek, bladeless fan is sure to impress virtually anyone, but techies will especially appreciate the engineering behind the Dyson Air Multiplier.  The Air Multiplier uses an airfoil-shaped ramp to amplify the airflow 15 to 18 times to create a cool blast of smooth air without the unpleasant buffeting caused by spinning blades.

With no blades, the Air Multiplier is safe around kids and pets, and it’s easy to clean too. The touch-tilt feature pivots on its own center of gravity, letting it stay put without clamping. You can also adjust the airflow to get as much as you want. There’s no “high,” “medium,” or “low”; the dimmer switch lets you set the exact power level you want. The Air Multiplier oscillates with a touch up to 90 degrees to cover a whole room.
