All tests were done with the
Low Friction PVC Stator/Rotor.
I decided to make mine more like Mikos's. I found out that the diameter of
his is only 2.4cm so I trimmed mine down to that. I also removed the wax
insulated from the needle end and insulated it with black electrical tape
instead. I also decided to try a simple coiled wire as per Miklos's
original one.
The needle end with the extra wax insulation removed.
A simple coil is on the other end.

Here the needle end is insulated with black electrical
tape and the end of the coil also has black electrical tape insulating it.

Previously I'd been hanging the devices from a string. Suspecting the string
might be acting a bit like a conductor, I replaced it with black electrical
tape as per the picture below.
Initial tests with this modified device were much the same as previous
tests so I increased the distance between the top and bottom of the rotor
with respect to the top and bottom of the stator (basically made the stator
taller). This was to reduce electrical interaction between the devices and
the horizontal members of the stator. See the following picture.
Finally, I did the new tests. I tried with spacings between the end
of the needles and the coil of: 11.5cm, 10cm and 9cm. I tried with various
starting positions for the rotor. Miklos was only able to use 27kV, having
only a monitor type power supply. At any voltage between 7kV and 40kV the devices
were silent and no movement occurred. This means I was
unable to replicate Mikos's results. Above 40kV there was a clicking
sound at the coil. At highest voltage of around 70kV there was occasional
movement but given the clicking sound, the movement was likely due to
ionization.
I next replaced the simple coil with the same single loop wrapped like a
rubber band as used in the September 7th
tests. I had the same null results for below 40kV,
the range that Miklos worked in. Above 40kV there was more and more hissing
as voltage was turned up. It moved vigourously at around 70kV but with a
lot of hissing and visible corona at the locations in the picture below
(the corona is not shown in the picture). The movement was obviously a
wind effect and as such, not interesting.
