I was in Michigan and on my way there I stopped at a casino. In the restroom there is a Dyson hand dryer. It has so much power it is ridiculous. I looked them up online, they show the motor that Mr. James Dyson was holding and it looks like it is the size of a small soda can. Ok how can a little motor like that develop that much wind, and how long with that motor last?? Thanks for any info. Mike.
