    Lightbulb Is there a future for fan blades?

    So, will we still be using fans in 30 years time?

    Superb bit of product design!

    However, there is still a fan - it's in the base!

    Maybe a diagram of how it works would help. I am as confused as the guys on the video.
    In the beginning there was the Cube; I know where is came from and it has the power to create Hover life. But with great power comes great Fun.

    Looks like its using the venturi or jet pump effect - would that be correct?

    Ah yes, but the difference is you don't get "chunks" of air like with a standard desk fan.

    Chunky air, ffs!

    I seem to recall Jetex did something similar on their model engines about 40 years ago?

    'Chunky air' = air turbulence= noise. So at first glance this should be quieter, but the Dyson website makes no claims as to noise. Is it because the high pressure fan in the base isn't quiet?
    Is the website suggesting the fan in the base is shifting 27 litres/min then because of the 15X amplifier effect the whole thing is shifting 400 litres/min?
    So why isn't this applicable to a hovercraft thrust 'fan'?
