Anyone seen bladeless fans in a pc size?

    Well if you want to get into semantics, fine.. But I stand by my point. If it offers nothing useful then I see nothing wrong with saying it offers nothing.

    and mesh and grilles accumulate grime and reduce airflow.

    Still, you have to pay the piper at some point, but hiding the impeller isn't really different to choosing a non-axial flow bladed fan like a centrifugal model.

    A reciprocating compressor is another bladeless air mover option.

    So too is a convection chimney.

    edit: or you could build a tesla turbine.

    Or even just a rotating cylinder will work for small movement.

    Or lobe style designs like a roots supercharger.

    The Dysons ones range from $380-$700 depending on the shape and size. They do have excellent air flow for a domestic fan, the sound isn't really that loud either. Very similar to a metal blade fan. Definitely not quieter though.

    of course some may prefer a good ol' dick zapping with the ionic lifter things - to each their own :p

    I had a bladeless Delta after I introduced it to a screwdriver... didn't push much air after that

    Dyson Air Multiplier certainly isn't cheap here in Aus from my quick search just then...

    Yeah there's an impeller in the base that generates the airflow required to create the low pressure difference which leads to more airflow (hence 'air multiplier').


    What really gets me? You can pay $400 odd for the small one, or $6-700 for the bigger models.. Why not just spend that $600 on a nice split system inverter? I know you can get them for that much, I just put one in my room... Can't install an AC? Get a nice portable inverter AC, again for the same money or not much more then these ridiculously overpriced fans.

    Just asked my old man if they sell many (salesman in a electrical store), enough to bother keeping on stocking them surprisingly. Apparently people have more money then sense.

    Or people who have realised that you can't put your penis in a split system AC...
    Unless you want a split system penis :lol:

    I do believe that may be the story I was thinking about earlier. If the 2.7m/s air speed holds constant at larger sizes (and if my math is correct), a 120mm fan would be moving 82cfm, all with no moving parts. That would be pretty damn impressive.
