James Dyson (above) says:

I’ve always been disappointed by fans. Their spinning blades chop up the airflow, causing annoying buffeting. They’re hard to clean. And children always want to poke their fingers through the grille. So we’ve developed a new type of fan that doesn’t use blades.

livescience says:

The conventional fan relying on blades has been largely unchanged for about two centuries; the first mechanical fans are said to have been built in the Middle East in the early 19th century. Ceiling fans blew onto the scene in the 1860s, powered by running water and a setup that turned a series of belts with the ability to operate several fans at once (some of these still exist in old buildings). A personal electric fan hit the market in the 1880s.

if you follow the link to the dyson page at the bottom, there are loads of videos explaining the whys and hows of the idea, which are well worth watching. another genius bit of product design from dyson!

thanks rob!
