here ya go Linky By the man himself

Yep, that link explains it better than I could!

It's a clever idea, although I'm surprised there isn't a fan that can do this already as the principles used here are some of the most basic things that aerodynamics/fluids students learn. Perhaps it just needed someone to realise the commercial potential! They put the Coanda effect to good use in aircraft, and even to control some types of UAV.

I bet they are going to be quite expensive, but they do look cool

£199.99 Whatever size.

Don't they have a fan in the box underneath the ring ?? So not really fanless. But very clever.
