Well, I must confess to being skeptical about such claims and when there appears to be a clear attempt to mislead, it heightens my doubts even more.

 

Here is what I found, first, it DOES have a motor and Fan Blade – so why the claim it is “bladeless” .  They appear to channel air up to the ring and with air flowing from the slits (air motion caused by the fan blades in the base of the unit) causes external air to be channeled along with the fan induced flow.  A Bunsen burner does the same thing in principle the hot exhausting air pulls in fresh air at the base.  Now the real question is how this fan induced flow  is capable of inducting a 15 time greater flow of air.  The principal would appear to be the same as exhaust augmentation with a lot less energy.  So don’t see any deifying of the laws of physics so far.

 

 But,  if it works for the dyson fan, then why not get 15 times {:>) your current cooling air flow sitting on the ground with your engine running?:

 

Dyson unveils blade-free fan

The Dyson fan has a conventional motor and fan blade in the base. The air flows from the base into the upper ring structure. No magic there. The magic is in the ring structure, where the air flows out a slit around the front edge of the ring. Here a process called inducement is put to work. The air flowing out of the slit recruits surrounding air because of the configuration of the slit. So now there is more air flowing through the ring structure than there would be from the base fan alone. Dyson claims that inducement creates a 15x amplification in airflow. Hence the name “Dyson Air Multiplier”.

 

I think I’ll wait a bit before buying stock in the company
