How does the new Dyson fan with no blades work?
I was watching this Dyson commercial for a new kind of fan that looks like a circle and has no blades but yet it emits a steady stream of air??? How in the hell does that work? The guy literally put his hand through it!!! Could you please help me figure this out??? Thanks!

How does the new Dyson fan work?
Fan, Air Multiplier, Air Cooler, whatever. I experienced one that was on display at Kohl's. I assume that there is a fan in the base facing upward, and that the air is split and directed by plastic baffles. But that is merely a guess. Do you know how it works?
Hi, it's Ryan from Dyson Customer Service. Air is drawn into the base of the machine which is then forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating an annular jet of air that hugs the airfoil-shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15-18 times depending on the model. The result is a constant uninterrupted stream of smooth air.

Does a Dyson fan cool the room better than any other fan?
It is starting to get hot where I live and I need a fan! We are not allowed to have air conditioning so I am wondering which fan works the best to cool a hot room like an air conditioner.
how can you tell which fan cools the most? vornado?honeywell? holmes?
No. It will not give you more cool air than a conventional elec, fan and aircon unit can give. This will only gives a low breeze of air, but will not cool off your hot body and room temperature. The air flowing from this fan is also dirty as the air is coming from under its base. There is a small vacuum fan under its base that draws air inside that goes up and out thru its big loop ring structure. So the dust and dirt around its base is being sucked up by this vacuum fan and distributed out on its ring structure. Beside it is too expensive than a conventional fan. I suggest to look for a water mist fan, a combination of ordinary fan with a built in misting system, like this one in links http://www.watermistfan.com/ How does Misting work: When ultra fine water droplets by our misting nozzles are introduced into the atmosphere, they quickly absorb the energy present in the environment and boil off (evaporate). The energy (heat) that is used to produce this state change from liquid to gas is eliminated from the atmosphere, hence the air is cooled by the process called evaporative cooling. Zouway high pressure misting fans and misting systems are designed to efficiently introduce a super fine mist into the area to be cooled which almost instantly evaporates (flash Evaporative Cooling). In the case of our misting fan systems Zouway are able to combine evaporative cooling and convective cooling (wind chill factor) to achieve spectacular results. Our fog nozzles are design to produce a very fine mist in order to get water to evaporate quickly. Misting fans have been used for decades for cooling outdoor climates. The science behind misting is simple. By forcing water through tiny misting nozzles at high enough pressure, a micro-fine mist is created, drifts in the air and then almost instantly evaporates. This evaporation process actually "uses" heat from the air, and the result is dramatic "flash-cooling" of the surrounding space. When the mist is blown with fans, the evaporative cooling happens quicker and the wind itself is cooled as well. Have you ever gotten out of a pool on a breezy day? You were feeling the evaporative cooling of water from your skin, combined with the convective cooling of wind. This is the effect of misting fans
Would marrying a Dyson fan to a cold air intake increase engine power?
The more volume of air being forced into an engine the more power right?
I'm just toying around with random ideas for now but I would like a serious answer. :) thanks
This is what turbos and superchargers do. If you could use the same sort of intake manifold that one of these uses and attach a dyson it should work. However turbos don't spin at a fixed rate as a dyson does thus it will produce varying amounts of boost relative to engine rpm. So you would need a variable speed controller to increase and decrease airflow relative to engine rpm to get the same effect.
