Hi Derek; What you see is conductive plastic film riding on the rollers
attached with copper tape, rollers are PVC and aluminum tape covered
acrylic. I did do comparisons, plastic film produced 30% more current. Belt
Is neoprene.

Doug,
From what I can see from the videos, you are using a thin piece of
copper for your pickup. Have you done any comparison between that, wires
or gauze. Do you see an increase in current or voltage ?
What is the composition of your rollers and belt ?

Hello Derek;
Thank you for your comments and including a link to my youtube video. I
have included a link to my youtube page so you can take a look at some of
my VanDeGraaff projects. I think all VDG builders are using the wire or
screen type pickups on their VDG’s, I have found something MUCH better.
You can see it in operation in some of my videos.
Hello; I am looking for some information concerning Ignition coil HV
supplies. I am using 120V mains through a light dimmer and wonder if
there is something better and more robust than the dimmer? This Ignition
coil HV supply will be a dual coil setup using a 25.0uf/370VAC motor run
Cap.
Not as cheap..
any of the standard capacitor discharge electronic ignitions basically
put 400V pulses into the coil to generate HV.
6000 RPM in a 8 cylinder engine is 200 Hz
typical energy per "pulse" is 100 mJ so 200 Hz is 20 W
