it's more cooling but it feels like it, apparently."
So mr Dyson hasnt actually tried it himself then?
How long can i resist the temptation to drop a V8 in?

Air Conditioning can heat and cool so take out the ac and you have no heating in many cases, so you would put in a traditional heating system along
side the new fans - but gas heating is not as enviromentally freindly compared to ac so kinda defeats the object.
Also does he not know that the naturally ventilated building concept never really works - if your in an office and you open the windows you get
traffic fumes and noise coming in.
oh and warm air too!
He's not thought it through!!

link to a critical review. It does
have blades, they say, but they are hidden. I think you can pick up from the tone that they don't like it much.

Well according to the mirror he stuck is face into it..
linky
The mirror probably has the best explanation on how it works, it's just entrainment, same as a normal fan but without rotation, quite cleaver..
i.e. a fast moving stream of air en-training the rest of the flow.. I doubt it much more efficient than a normal fan..

Agh... clever concept...
One flaw though...
Every single dyson product to date has been stupidly noisy..... and moving air using a small high speed fan in the base and then forcing it out of a
narrow hole... is going to be equally as noisy
Slow spinning and quiet large diameter fan for me please

ah, that makes sense. very clever. same sort of principal as the things that inflate aircraft emergency slides isn't it?
in those i think theres a small explosion which fires down a tube to the slide, but some trickery in the tube draws on hundreds of times more air to
inflate the slide

Air amplifiers like this are nothing new... In fact some were used on scrapheap challenge this year I believe...

Can’t quite understand the phenomenal price for it tbh and an office fan these days isn’t dangerous due to the cleaver invention of a guard round the
blades…

The Dyson hand driers are good - they really do dry your hands in a few seconds.
Quite amusing to watch the people who don't know what you're supposed to do with them...

I don't really like our Dyson vacuum, it is heavy, noisy and overengineered. Presumably it has a similar power requirement to a regular fan?
That is a lot of litres of air - any ideas what that would be on the Beaufort scale?? - sorry boss, I could't work as it was force 4 in
here....

came across them in an airport, rather scary to use I thought  kind of thing I'd expect a tie to vanish into and throttle the user
I can't fault the vacuum, the abuse I've given mine including sucking up water, wet plaster, even empting bean bags...boy do those little
beans move fast and the things still works just as good as the day we bought it. Is louder than most vacs admittedly.

So imagine getting one of these to work in reverse and suddenly your wind farms no longer chop migrating birds to bits...
They just mince them in the base

Saw something like this being used to cool F1 drivers whilst sitting in the car in the pits.
A small (4 inch) ring with an air line attached.
Can't find any pictures, though.
