I have had joy in the debate of AC?DC in the ion field of the TC.I JUST
LOOKED AT US PATT. 645,576 AND FOUND TESLA DISCRIBING THE SAME SUBJECT WE
HANE BEEN DISCUSSING. I think we should review his concept of the whole
subject.He found that the ion cloud went much further than we have been
discussing here in the net." the big picture"
