I wonder how well Dyson's new air "multiplier" fan thing actually works?
As an aside, did you know James Dyson is British? I thought he was Swedish for some reason.
Anyway, the air it's blowing is pulled up through the base, presumably with regular fan blades -- I mean, it can't be another "multiplier" in there, right? The multiplier doesn't actually get any air moving in the first place, it's just the way that air gets sucked into the flow-stream. So then the air has to get pushed up, and through that narrow opening and out. So I can't imagine it's any more efficient than a regular fan with the air having to turn all those corners, nor can I imagine it actually moving much air. And based on their drawings I'm pretty sure a regular fan does all that same "multiplication" stuff too.
Still, it does look pretty cool.
