Bladeless fan!

ummm... are saying the techonolgy is old because it has an electric motor stuck in its base?

the hoop/aerofoil bit on the top would be new or old tech?

No, SE and Sms have more or less said what I think, that is the principals used are nothing new. You may or may not have studied physics at school?
Consider how a soda syphon works; air blown through a tube sucks in other air when another tube is inserted at right angles - nothing new about that.
As sms says in so many words: 'a novelty.'

Well... here is where this 'amplified air' thing falls apart. If it really is accelerating nearby air, then energy is required to do so. The only place this energy can come from is the moving air. Now, maybe they are trading velocity for volume but the point is that however much energy was put into the air before it is blown out the aerofoil is exactly how much total energy the fan can produce.

yes sir, unless... they have developed one of those free energy developing devices there could be a market there!

refined induction is what they are talking about, much like a Carburetors fuel jets (plavts soda syphon), replace the fuel with air.

"The breakthrough came when they noticed that accelerating air over a ramp amplified it by 10 – 20 times, drawing in surrounding air through processes known as inducement and entrainment. Hundreds of iterative tests revealed the ideal ramp angle, aperture width and loop amplifier dimensions."

this sentence is quite amusing i thought;

"One engineer had the original idea. But it took every discipline from Dyson’s 350-strong team of engineers and scientists to develop Air Multiplier™ technology"

i'm guessing the tech might be a wee bit more complex than a cars a/c ducting or that "350-strong team of engineers" must be real silly, how many disciplines are there?

the study of fluid flow obviously isn't a new concept but the tech (the practical application of science to commerce or industry) certainly is wrt to this fan. lost in translation.

when the dyson cyclone vacuum cleaner came out, i thought it was revolutionary but it was just too expensive for me. so i stick with my bog standard bag vacuum cleaner.

then my brother gave me his dyson. in comparison, it wasnt something out of this world in terms of a good suck. my brother got a miele (bag type) instead and he said it was better than the dyson!

but if you look at the vacuum cleaner market, they are all similar to the dyson cyclone concept. so one day, i am sure we will see "balde free" fan soon flooding the market.

still... i still got a soft spot for the henry vacuum cleaner. (www.henryvacs.co.uk)

Thanks mrlily, for repeating their ad vertim. I think we've all read it by now and we've all, 'cept for you, anyway, realized that it's old technology that's been refined and presented in a new way. Therefore, a novelty. Albeit, it might have taken 350 engineers to figure it out. Might also say something about the level of today's or Dyson's engineers.

Credit where credits due though. It is a novel concept, but it's NOT what they claim in as much as the air is driven "just like a turbine" (based on impellers which are blades) which initially chop the air but then constrict it's flow before allowing it to pass through a smaller orifice thereby negating the buffeting effect.

last word?

the idea of sending air through the internals of an aerofoil shaped hoop thus inducing a larger volume of air is super smart.

how they send the air to the aerofoil... is irrelevant.

[sundaymorningstaple]

I think we're having you on a bit cause you bite so easily!

Just taking the p*ss that's all.

But the concept is very old anyway. Isn't that the same principle that used in the concept of the bog standard flush toilet? Even forms a hoop around the bowl. Just uses water instead of air. It also collect all the other water already in the bowl and out both go, volume increased as well.

If the method of sending the air is irrelevant they why did they go to such great pains to not only explain the chopped air effect but draw pretty pictures of it as well?

Bet we all know who's gonna buy one!

[mrlily]

snap, snap snap gater boy, hook line and....

[durain]

if it is made in singapore, i will buy it. unfortunately, it is made in malaysia.

No different to the vacuum suck and blow concept, that many vacuums' have! The only thing with dyson is their design concept, which you pay for. I prefer the industrial VAX for simple effective air flow which is all relevant

While on the subject of vacuums, I just went to harvey normans and bought a electrolux "Ultra silencer" its so quiet didn't even know our helper is vacuuming.

Heres the thing, does Philips pay a bigger commission? The sales folks were really pushing Philips this and Philips that, saying the electrolux is so quiet the motors burns out quickly because of all the filters, I should not vacuum for more than 15mins with out turning it off!! Made me wonder if I have Mug tattooed across my forehead? What firm would make a cleaner that works for 15 mins before over heating.

No... but if you really look like your Avatar, it might be the equivalent.

was walking through IMM a day or 2 back, turned around and my daugher was about to lick (don't ask why) one of those dyson bladeless fans...

here is my concise product review;

1 - look great!
2 - noisy
3 - noisy
4 - did i mention noisy?
5 - i could blow harder with a collapsed lung
6 - expensive sial!!!

conclusion:

Since Mr Dyson is very good at marketing his products and stringing the public along

[durain]

had a play with one a while ago too. at full speed does sound a bit noisy and at low speed, you need to put your face next to it to get any air!

still, i will wait for dison brand (and not bladeless fan but fan without blade) from china.
