Drawing 150 volts from a plasma lamp running on 4 AAA

Playing around with my plasma lamp again last night.

Before I was getting around 70 volts at the penny nodes... 

Messing around with different configurations of things I learned that if I place a conductor below the lamp it significantly increases my power output.

I'm assuming this works on some sort of polarity principle since there was conductors at the top and not bottom before...?

Anyway after a few tests I set it on a piece of copper clad.

My voltage at the penny spiked to 145 volts. I am sure this is very low amperage. Next we shall try hooking a light bulb to it. 

And creating leads to my radionics box.

Here's some pics.
