The principle here is basically fluidic, specifically (I think) it is called Coanda Effect, named after one Henri Coanda. To Mark Harrison's question, I think it can be ceiling-mounted with only the annula showing as long as the concealed base is supplied with sufficient air from the ceiling space. This air is important as it is the driver of the effect, i.e. this primary air flow creates the "inducement" & "entrainment" that gives rise to the resulting large volume of air that carries out the blowing work. Really, this thing can be applied to many other fan-based applications, such as air-conditioner, exhaust fan, etc. To answer W’s question on whether the technology can be applied to power boats, I think it should be possible as water is just a much higher density fluid, but still a fluid.

The basic idea is you release compressed air through a couple of jets, and the expanding air carries along adjacent, stagnant air, from the surrounding volume. Can be very efficient. High cool factor, but it would be nice if the PR and Dyson site put their products in perspective.

Yes, both technologies (airfoils and fans) have been around a long time, but their implementation and execution together is both new and exciting. This is the difference between Ives and Dyson, invention and innovation. Max,

They're offering free shipping on all fans until Oct 23! www.conranusa.com This fan is amazing, I just saw it in person at The Conran Shop and they look great.
