Dyson's bladeless fan

An interesting non-RC invention. Could the Dyson air multiplier ever have an application in EDF? Probably not, but cool to think about.

If they could get it to multiply the air 400x then we might have something. But it would nned to be smaller.

interesting design, but its not bladeless. The video clearly shows the blades in the fan housing. All the fan does is take the hp air from the fan and blow it out the ring. It uses the velocity out the wing to combine with other air to provide more volume.

its like taking a house fan, putting in a right angle duct and calling it bladeless.

Article says its multplies the air by 15X, but what does that really mean? and 15 times what metric, more volume, more pressure at the acutual fan??

"118 gallons a second," who measures air flow by gallons per second?

It already does ... if you had taken the time to look at the video you would have noticed the simple brushless fan in the base of the unit ...

Now, what makes you think I didn't look at the video.

Sheesh. Rough crowd.

If that is a fan in the base, why is the hub huge and the fan blade area so small?

Nah don't take it personally

There are no miracles in air flow esp. with such trivial devices ...

I didn't genuinely believe there was. I posted it mainly for amusement and the gee whiz factor.

The man is a good engineer. I have one of the vacuums (the one with the ball) and it is a clever bit of design.

long long time ago there was a electric fan with no blades. it moved the air by charging molacues or atoms with magnetic field. have plans. wind wire around nails in a circle 8 or 10 nails

Sounds like those Ionic Breeze gizmos that were popular a few years ago.

It would make a good wind tunnel fan.

I think it works sort of like a venturi pump. You take small diameter, high velocity and use it to move a large volume at low velocity. The only good thing about this is the safety part, because I'm sure we've had enough people die from small household fan accidents

Medium Eflux low-pressure

Hi all,
What you are looking at is a vortex air amplifier with a nice modern twist. There is a company called Vortexair and their e-mail address is Vortexair.biz. They explain how the whole system works. Good for medium volume Eflux, low pressure. Would make a nice fan but that's about it!
