Very nice design like all Dyson products. The cost puts it in a gallery rather than in a home however. There's no way I'm paying a 10x premium for 'cool'.
the only comment I can make here, is " COOL ! " !
Okay, there is a brushless motor in the base creating airflow... But HOW does it create the airflow? Is there not a fan attached to that motor pushing air into the ring? Some clarification would be appreciated...
I'm wondering about the noise levels and whether this could be adapted for use on CPU coolers in PCs.
tjshire, the article never said it has no blades. It says there are no VISIBLE blades. There's obviously some kind of impeller within the base, hidden from sight.

The design utilises the venturi effect to produce the airflow. It will utilise a fan (most likely) in the base to create the required air pressure to get the venturi working. Basically, you inject air radially around the circumference towards the direction of required flow and the resulting low pressure generated behind this point draws more air in...
Very simple and if you have a compressed air system, no moving parts at the unit. Good for stirring up air or dust/gas extraction with no electrical components.
Wow. This seems to be ideal for kids rooms and even hospitals, or anywhere else where a fan is needed but the danger of spinning blades is not. I can imagine a time, not very long from now, when having regular fans in the nursery will be considered criminal child endangerment. $300. is cheap compared to the price of a severed limb, after all.

If he added a lamp to it (maybe an alarm clock at the base) it would be a brilliant addition to any room. You would not need to store it in the winter and if he made it a heater too. . . well, let's just say I'll order three of them!

I\'ve played with one of these are they are really cool. They put out a serious amount of air. Even having an engineering background with a ton of fluid dynamics, I couldn\'t figure out how they could generate such a volume of air with the way it is configured, but I would imagine that there is a venturi effect around the entire ring of the fan. Anyway, pretty pricey, but definitely a really cool piece of equipment.

Jamie or anyone esle who have used it,
How is the noise level? You need a vaccuum cleaner like motor and fan to push with the speed to induce the associated vaccuum in the venturi like outlet, is it too noisy?
