This device has the same setup as device with two ping-pong balls on an insulated wire, but here I use lighting bulbs. Lamp is good for vacuum test, since it`s good hermetically enclosed.
This setup has no ion-emitter on the stator, and rotor is very good, very thick insulated, with more differente insulation layers. These, differente layers are important for working. Nothing in this setup is makes ions outside of lighting bulbs. It works on 30kV, and current is so small that I can`t it measure... But device moves very fast!
