Anyone see the Dyson fan? Really cool - no blades! Pushes air by way of intaking a small amount of air though an enclosed impeller, then passes it over an airfoil thus 'speeding' the airflow, the result is air blowing at 15 times the initial airflow of the impeller, but NO BLADES - it just blows out of a round housing - really cool. Wonder if it could work for an electric cooling fan for a car. Would have very little amp draw I'd imagine, no blades to 'cut up' the air as it's passed through, so a steadier stream of airflow, and no loss of fingers! Check it out at www.dyson.com

 

And I'd be willing to bet that there is a fan.....In the base.

Look at all the vents in a circle. Fan in the base pulls air in, blows it up to the ring on top, which has a slit in the ring to blow the air in one direction.

They try to claim no fan. I call ! The fan is simply hidden from direct sight & line of hearing.

 

Yeah, there is a small fan in the base that pulls air in. The trick to it is magnifying it through the use of the airfoil. I'm not thinking it would actually push or pull more airflow than a standard bladed fan - but from the pictures I had the impression that it might do it way more efficiently. It makes sense when they discuss the buffeting of the air, how a blade cuts the air into chunks, and thus literally blows 'chunks' of air out. Whereas this design would tend to maybe hold a steady stream of air movement across the whole diameter and continuously outward maybe, producing a less interrupted airflow since it's not getting cut up. Was my weird thought anyway. It is a cool design, I'll have to see if there's a local shop around where I can experience it first hand.

 

They had some set up at Best Buy last time I was in there. Neat fan. But at $300 a bit too pricey for me.

 

Oh hell yeah - my $15 Walmart fan does just fine! I just thought it was a neat design, and that maybe such a design could be utilized in the cooling of an engine.

 

awesome looking fan and idea, but size would be pretty prohibitive due to the design.

 

There are compare and test videos on youtube already. Fan looks cool but not $300 cool. It's also about as noisy as a regular fan and works no better, about the same. I'll wait for the knockoffs.
