Default Water vapour speaker?

We all know the water bending experiment with a charged comb. Does steam behave this way? How about charging some steam and passing it over some kind of conductor with the opposite charge modulated with a signal?
I could write more but I think the mechanics of such a thing are fairly obvious

Anyone ever tried this?

The mass of such a diaphram would be quite substantial, no ?

I recall reading more than a decade ago ... a speaker that used ionised Ozone, as a diphram responding to an electric field....

Question Steam powered speakers

Bigwill,
What sort of steam did you have in mind Dry or Wet ?
Wouldn't wet steam be rather a problem especially in a humid climate ? And dry steam is just downright lethal, we use 350 deg dry steam @ 700psi.
Perhaps modulating a high pressure feed would be the answer, we could use the steam to move a small piston connected to a loudspeaker diaphragm

What I had in mind was small jets of steam fired at some kind of mesh with a high voltage signal applied to it (as well as a high voltage bias)

The steam would be attracted (or repelled depending how you charged the water) in sympathy with the audio signal, hopefully creating pressure waves

An ionic breeze converted into a speaker using water vapor (ultra sonic mister or something) sounds like my idea of fun
