Swaying CPU Fans

Vindi submitted a New Scientist story about a CPU fan that flaps in the breeze. 2cm metal or polyester fan blades, and use less power then a traditional rotary fan. They move less air then the traditional fan, but for laptops, using 99% less power can't hurt. Update Hey its a duplicate from saturday! Guess I shouldn't post while planning my trek to see LotR tomorrow. Go ahead, flame on.
