By L1 do you mean the primary? I think on a very efficient switching circuit, voltage multiplier might end up reduce the secondary voltage.

TT Brown mention that static high voltage produce dampened acceleration. It will accelerate for 5 second and then reverse a little. Forget where I read it, sorry.
Maybe 50KV produce bigger thrust, but without pulsing, we only get momentary acceleration.

yeah!
now i am fully concentrated in my plasma propulsion lifter, i hope that tomorrow i can have the video ready!!

I see. How do you obtain straight HV DC? did you use capacitor?
Even if you use a monitor as a power supply, im pretty sure the HV DC will be pulsed. My HV power supply is certainly pulsed. I thought it would be pretty impossible to get DC into the 20kv range without pulsing it in some way....
....but perhaps its possible with caps?

I found a 100g payload experiment but it didn't have a helium balloon.
Experiments: Experiment 14
Is there more than one?

but the power supply that i built used a voltage multiplier that was made of diodes and capacitors and thus a strait DC output, I actually had to discharge the power supply after every use

Thank You very much
I was having trouble finding it - much appreciated."Amy Pond, there is something you need to understand, and someday your life may depend on it: I am definitely a madman with a box." ~The Doctor

@ Serfer5,
I'm trying to understand the action that is causing the thrust.
You said "the resulting movement is from the build up of the dc charge", and I find this intriguing along with the fact that you have demonstrated quite nicely for us that the motion occurs after the capacitor plates are charged up and not before.
So I see it this way; that the increasing charge results in a higher plate voltage and thus a larger static E-Field between the plates but at this point a lower current flow into the capacitor (depending of course on leakage).
Therefore, the thrust seems to be associated with the stress or tension in this E-field rather than some kinetic 'action - reaction' of charges moving from one place to another. Am I on the right track here?
I think I need to do some reading on the underlying principles behind this phenomenon to better understand the concepts being applied
I love learning new things"Amy Pond, there is something you need to understand, and someday your life may depend on it: I am definitely a madman with a box." ~The Doctor

YouTube - First lifter with TV as HV power supply
It was pretty easy to get stable.

this particular thuster video made a lot of people think because the time to charge the plates was too long for what would have been expected, what you cant hear in this vid is the moment the power is turned on there is no sound then just before it starts to move there is an increase of hissing noise.
I can't explain it my self

that looks about what i had with my first attempt

As the OP stated to be interested in all kinds of levitation:
In Nijmegen, (Just around the corner ;-) Netherlands they have a lab in wich they levitate objects with magnetism.
