The Dyson airblade is based on a very narrow, high-speed jet of air. I'm not sure that it does suck, but it certainly blows...very hard. It definitely collects the water blown off the hands, and atomises said water periodically into the atmosphere.
I HATE hand-driers. What a noisy waste of time, space, energy, everything. If your hands are damp wipe 'em on your bum. That's what it's for. Even if you don't do that they'll be dry in less than a minute especially if you rub 'em together briefly.
The most impressive drier I ever saw was in a bar in Dresden. It was called the 'AirWolf' and my (German) friend remarked that it appeared to be based on Rommel's desert air-conditioning system.
Conventional hot-air dryers actually work and work quickly in Alberta. Something to do with the altitude, I've been told. After a few dryings your hands are like lizard skin though.
