Dyson Bladeless Fan
The name Dyson has been associated with innovative household cleaning appliances, such as vacuum cleaners. The Dyson Bladeless Fan is next generation oscillating three-blade portable fan. The Bladeless consists of a ring sitting on a stand with no visible blades or cage. The technology behind the Dyson Bladeless Fan is called “air multiplier.” Inventor James Dyson explains the concept this way: traditional fans cup up air waves and propel them out, but the Dyson fan (since it has no blades) provides a constant air stream with no chop. Dyson also claims that the Bladeless fan’s lack of blades also makes it safer, especially for children’s rooms.
The Dyson Bladeless Fan retails for about $300. Read more about it on the Dyson website. You can see air multiplier technology explained in the YouTube video:
