Blade-free fan

What, a fan with no blades? Yes, that's exactly what you're looking at, and what makes the Air Multiplier so hard for people to classify at first. This fan uses some innovative airflow engineering to pull air up through an energy-efficient brushless motor base and multiply it 15 times, expelling it through an airfoil-shaped ramp at a rate of 118 gallons a second, according to the press release.
