our working group was able to replicate the lifter 1 experinent succesfully.
High voltage supply is a EHT multiplier(from a university) with a max. of 50KV pure, not pulsating DC, voltage finetuning, change of polarity, and scales for the actual OUTPUT voltage and current. current up to 2,5mA.
Device was lifter 1 with adjustable wire and weight of 3g.
The shapes of the top part of the foil were mostly very well rounded !
wire CuL with 0,16mm diameter
The wires from the high-voltage supply were partially covered by teflon.
Our solution for adjustable wires. its a blade of straw cut in pieces, glued with cyanacrylate-gel.
lift-off voltage with 31mm wire distance was 18KV and a current of 250uA
lift-off 25mm 15-16KV 250uA
lift-off 20mm 14KV 450uA
polarity on the wire in all 3 cases was minus !
weak hissing sound.
if you start calculating the lift-off power is between 2,2W/g and only 1,3W/g.
The results were:
polarity minus at the wire and weak hissing sound we
used a pure DC and the values above are mere output taken from
the scales of the high-voltage power-supply. we were suprised,
too. our rough estimations about real losses are another 200uA of
the measured currents above. that means a real needed power for
the lift-off are in our best case
250mW per gramm.
