Roll up roll up, for a very different but effective wireless electricity coil design.

The Doob coil is, in effect, somewhat like a simple capacitor., with plenty of metal mass for capacitive coupling to surrounding receivers.

I was reading through previous posts about Dr. Stiffler’s work, especially on the archives of Energetic Forum and spotted the link to this coil. It’s on my Photobucket, here:
