All tests were done with the Low Friction PVC Stator/Rotor.

Second tests - didn't move other than due to wind forces (Sep. 19, 2005)

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.
