Few inventions have lent themselves to as little improvement over the years as the simple fan, with its whirring blades that blow air across a desk or through a room.

But now even the conventional fan has been transformed.

James Dyson, the British inventor behind the vacuums that bear his name, has come up with an incredibly simple-looking, circular fan that has no blades. It uses "Air Multiplier" technology to push 119 gallons of smooth air out every second.
