This was mentioned in the GoogleTalks and in the patent, if I remember correctly. At this point it’s a theory which seems to be proving out experimentally, but I may be wrong on that- the relative motion of ions and electrons are beyond my direct understanding of the process.

That’s kinda’ what I was thinking, which was why I mentioned it. It seemed to be ‘supporting evidence’ for the contentions made in the patent, and in the talk. I didn’t describe as well, though.
