They didn't. The fan is integrated in the base. Actually the fan example is exactly what makes me look at any Dyson announcements with a lot of skepticism.

That and "digital motors".

It's a bladeless fan, not a fanless fan. It works using an impeller in the base and it feeds the air through a thin gap in an annulus shaped aerofoil. Strictly speaking you could argue that impellers have blades and all they've done is conceal them inside the base rather than remove them entirely. A truly bladeless fan would use something like an electrostatic fluid accelerator to accelerate particles with an electric field - but that's probably a little too sci-fi for a consumer electronics company!

Jonny, you're RUINING THE MAGIC

Good to see other Dyson people on here.
