Although the Dyson vacuums don't rate very well in Consumer Reports testing, the air moving technology created by Dyson has resulted in other truly revolutionary products.  The Dyson Air Blade totally changed the nature of electric hand drying from an agonizingly slow bore to a high-tech speedy wonder: The air blade uses a forceful "blade" of air to squeegee all of the water off your hands in seconds.  Dyson has done it again with the Air Multiplier Fan — the world's first blade-less fan!  The innovative technology allows this sculptural ring to direct a forceful flow of air without any visible moving parts, blade or grill.  I'd read about it a few months ago, but finally saw it in person at Bed Bath & Beyond yesterday.  It's truly impressive, although so is the $300 price — a pricey choice if all you're interested in is airflow, but for design lovers, a chance to own something truly revolutionary and also functional.  Buy the Dyson Air Multiplier at Amazon.com, or save 20% at Bed Bath & Beyond with a coupon you can get by signing up for their email list.
