Theoretical concept: An idea about high voltage jet system
While playing with my new CW multiplier I noticed that in case I’m close enough I can easily feel on my skin something like a strong wind coming from the positive electrode. This must be charged molecules of the air. Now I have an idea of building a jet device using this principle. Do you people thing this could work? Does somebody know whether similar devices with some practical use exist?

WOOT ion boosters!
Deep Space 1 uses this technology:
Thanks for the link... You right. The principle is very simillar with the basic difference that I plan to use air and not xenon. Also, the used voltage is is much higher in my case. I'll probably give a try ...

This is an ion wind and "devices" using this principle are being built for a long time and they are called "lifters"

They're called lifters and they demonstrate the Biefeld-Brown effect. There is no actual "wind" or "air" moving because the lifters have been tested to function in an almost perfect vacuum.

I was one of the first on this forum to make a lifter and they generate a substancial flow of air. Please read some of the old threads to see the details of how the ions are created and move in the field.
The Biefeld-Brown "effect" is not an acceptable topic on this forum without hard proof (meaning better than this: ).

Er, wouldn;t this be ruined by the thing where charge goes to the OUTSIDE of a conductor? Shouldn't there be be no charge be observable on the inside of those toroids and very little on the "top" and "bottom" surfaces (the near-flat faces around the holes")? I don;t see how with this the incoming air would charge... Certainly an interesting concept you have there, it'd be cool to see it operate in open-air

Oh crap, I totally forgot about that. My apologies, please don't smite me!
Also I want to correct what I said. It wasn't a "lifter" that was tested in a vacuum. It was what's called an asymmetrical capacitor thruster that NASA tested in a vacuum and it was with only PARTIAL success. Lifters do only work in the air because of wind and air movement. I haven't looked into that stuff for a while and Bjørn's link was a little refresher for me. Again, sorry about that breach of the rules.
Anyways, back on topic. Your idea is definitely a good one. Except I think that narrowing nozzle will decrease flow instead of increase it. The wind isn't strong enough to push through. And I wonder if putting 3 electrodes at increasing tensions would act like an accelerator and get more wind than 3 at the same tension.
