I have seen many of his videos, Aaron, and he's a real developer. A little s-l-u-g-g-i-s-h in his presentations, but his data is sound.
As I have seen this video, and the materials I need for my plasma application, I will apply exactly what he's done here, with a little addition. I am going to to wind my plug wires with solid core copper speaker wire. To understand why, you would do well to look into the bifilar discussion here, and elsewhere.
When you do, start reaching for a feeling of flow-less frequency, for that's another discussion entirely!
