Sorry, no photos of the circuit up to now!
A Lifter is a very low weight structure which can fly if enogh ion wind is produced. It has NOTHING to do with antigravity and such things, as it will not lift in vacuum (http://www.blazelabs.com/l-vacuum.asp).
Daniel C. and I buildt two lifters (13.03.2005) but the output ftrom this DC-supply (approx. 0.5mA at 15kVDC under load) was much to weak to get the lifter up into the air. I let the one I buildt successfully hover with my 40kV Cockroft-Walton multiplier at the GTL-Teslathon2006.
Since smaller Lifters need less power, I buildt a smaller Lifter, which can hover up into the air, lifted up by the power of this high DC voltage. During lift-off, it is very unstable (though it has enough thrust), so I can't make the feedlines much longer. Perhaps a tail like the one used on kites will help here. Have to think if an isolating tail would be better than a conducting tail connected to the aluminum foil...

Since the two fine wires which deliver the voltage to the Lifter will attract
when they are to near together, a simple solution is to make a support and
provide one of the feed wires from above:

That circuit is really hair-raising (me standing on and isolated table connected
to this HVDC source at the GTL-Teslathon2005):
With the circuit, we let some charged soap bubbles float over a charged aluminum
area (the bubbles avoided to land on the alumnium):
They really jumped up and down when I switched the voltage on and off!

This soap bubble experiment was brought to the GTL's Teslathon2005 by the
nice people of the german popular science magazin "ZeitWissen", who made
a documentation of us which can be found here:
