James Dyson

You probably all know about the Dyson vacuum cleaner, invented by the British inventor, James Dyson. He is at it again and has come up with a bladeless fan.

It pulls air into the machine's cylindrical base with an impeller that draws from jet-engine technology. The air rushes up into a hollow ring and is then forced out of a slit that is less than 1/16th of an inch. The slit runs all around the ring.

As the air exits through the slit, it flows over the inner edge of the ring, which was modeled after an airplane wing. As the air exits the loop, the lower pressure pulls air from behind along with it, and air around the front of the fan also gets pulled into the stream.

The fan runs with a small motor, and airflow can be fully regulated with a dimmer switch. A 10-inch fan costs $299. Cool technology,  kid safe, and would look great under my Christmas tree.
