Yes, you did get rather excited.<----(thats an understatement)

Are you talking about using  the permanent magnet TCs for power distribution
or communication?
Seriously, all I was talking about is a generator/TC hybrid that makes
really big sparks. Nothing actually practical or radical.
 If Terry is kind enough to put the picture on the website, and I know he is
because he's  a great guy, ther is a rough drawing of what I'm talking
about:
