I think that the highly damped wave and tremendous peak energies in the
disruptive system will be the ulitmate causitive agent and explain the
lack of DC charging effects in the tube coil system. (your "B."
Again, I think that true rectification, as we know it, is out as an
explaination. Though, by some "liberal stretch" of the term we might
bring it forth. Alternating energy is producing DC electrostatic
