It is a bit a similar setup as Andersons work.
Low voltage and high voltage doing the work.
I think that a gas test would have been a part of it. Maybe he was creating D2 elements or something similar by hitting the molecules with the bemf pulse...
And that is what most of us are not able to perform.
Where i live, i only did once such a test and costed me 400 bucks.......
cheers!
