Now imagine what this could mean for computer cooling, all the advantages! You could cool a case more easily and efficiently because the flow of air can be controlled independently of where the air actually comes.
This almost sounds closer to air conditioning than to a regular fan.
It does use a type of turbine in the base, but still this thing is way cool. Moving the air up the ramp on the inside of the circle is really the key to grabbing air from all around it. This is really cool stuff.
Very innovative and all...but personally I've never been bothered by the awful stream of air a fan produces? They work fine for me as far as I know. Now if that option could work with very little noise compared to a standard fan, THEN you've got my interest.
A bladeless fan, but "Air is drawn into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil-shaped ramp."
So basically, they use a mystery device to draw air in and force it into the loop amplifier. $1 says they use a bladed fan to do this. In other words, this isn't a bladeless fan, its a airspeed/volume amplifier.
Nice try Dyson, but I left your overpriced and under-performing vacuum (according to Consumer Reports) on the store shelf, and I'll probably leave this $300 piece of crap there too.
The thing obviously still has blades... they're just hidden in the base where you can't see them. I have seen the concept of using an airfoil shape to pull more air used before... it definitely works and is very cool - but the thing isn't bladeless.
What I really want to know is, how quiet is it? As we are all well aware, traditional fans become exponentially louder the faster they spin. This is a direct result of the buffeting of the airflow and the reverberation created by the blades as they run into the turbulant air that they have created. This design, once the price comes down, could have tremendous benefit in the area of CPU cooling while simultaneously reducing noise.
Yeah, I can't help but think that there's some type of fan blade in there, if not, where does the kinetic energy come from? Aside from blades or pistons, there's not many ways to accomplish this, unless they've come up with some kind of sophisticated laser/radiation/magic way of doing it.
