Fantastic. I remember listening to Art Bell years ago, and he was describing how he'd erected an antenna for Ham radio or something, and how the tower began collecting a charge immediately, causing problems for him. He didn't go into it much more, just noted it, and said it was "interesting", in a way that meant something... interesting!
I'd like to know more about your collector, I'm intending to go off grid like that in time-- look forward to that 'how-to' post when you get it up and collecting.
