It's obvious. You don't need anything as crude and old-fashioned as a
piece of copper wire going to ground these days. If the device uses
modern technology, like reverse polarity ionization, hyper flux flow,
things like that, then it can all happen completely inside the simple
circuit the OP describes. Hell, it's not even as complex as a
transistor. Do try to keep up, there's a good chap.
