I note on your page that you are working with a van der graf electrostatic generator. Years ago I experimented with that also and found some interesting results.
From there I went to the Tesla Coil and have an idea that someone may have the time to try.
Make three phase arrangement of three tesla coils but wind them on a 1.5 inch poly propelene tube welded in a circle.
There should be enough ionisation occur to provide a lifting disc if set up properly.
You can either activate the coils by the use of rotating magnets or use a 75 Khz oscillator for each of them that can be done with a single oscillator through suitable transformer and tapped at the right points.
If you look at the Ufo displayed in the Adamski book Flying saucers have landed you will see what I mean.
The balls underneath are infinite capacitors and the top is an anode emitting the charge from the coils.
This should provide lift of 1/2 a psi onto a disc shaped contrivance.
The vander graf ball will spin a propellor if connected with quite some force showing that an ion wind has quite a velocity.
If you operate the machine in the pitchdark, you will see what I mean.
If any comments
Let me know

P>S. If there are any mercury freaks like me on your board let me know, I am also able to show some experiments there showing the awsome power that can be derived from it's use.
