It's not necessarily a more efficient fan than other fans (Dyson doesn't have any information about the relative efficiency of their fan on their website yet), but it's certainly an innovative design, and that could make it more acceptable to have a fan in a space, where a conventional bladed fan might be objectionable. The noise level from this fan is also not indicated yet. The sleek appearance of the Air Multiplier also makes it easier to clean than bladed fans. However, the Air Multiplier is not truly 'bladeless.' The blades are just concealed in the base of the unit.
Fans can be a far more efficient method of cooling than air conditioning. Moving air can provide a cooling effect with much less energy use. The Air Multiplier offers a stylish way to do this. While it has just been released, and availability is limited, it will be interesting to see if the performance of this fan makes it a real winner, rather than an expensive curiosity.
