Jetijs,
I have noticed that neon bulbs are good indicators of aetheric density when touching with only one side.
I constructed a simple boost dc/dc converter (i.e. coil pulser) and I attached different types of diodes to the output while touching the output of the diode with a neon bulb. I used 1n4007 at first and it was lighting abit dim, Then I used 1N5408 and the bulb was a bit brighter, and Then I used a 6A4 diode and the neon bulb lit much brighter this time. This brought me to the conclusion that thicker elements make aether transfer much better.
Some time ago I used a normal 12v bulb instead of a neon bulb and I could also light that with one wire!!! and I am pretty sure I did this, but I can't do it now!

I don't remember if I did something special.
