Larger Diameter Plate - Single Pulses Then Multiple

In this test I tried the same configuration but with a wider diameter plate.
Diameter does not seem to effect force and from previous test neither does thickness
of the plate.
Another thing I learned is if you test a new configuration and it does not move much
then you walk up to it after turning off the power and touch it all that charge
is stored in the plate and you get a huge shock and arc.
If you have a good test with a lot of movement and do the same
there is very little charge left in the plate and it is just a tiny shock
and arc. I plan on conducting experiments to find designs to get the charge moving out
of the back of the plate as quickly and efficiently as possible.
If you are curious how I could do this or have
your doubts I can, check out this video on ElectroBOOM site on Youtube.
Go to 8:10 and watch until 9:20 as he describes what is happening here.
Glad I found a video with a reputable source describing what I am doing.

Only connection is the positive hot wire, no negative no ground.
No ion wind and it works in a vacuum as I have shown in previous test.
Constant acceleration in space in one direction.
Only fuel is electricity.
Just testing multiple configurations to get the most force.
