Abstract

A circuit includes a first source for providing an alternating electric field, a directional circuit connected to the first source for providing an alternating electric field by a transmission conductor there being no conductive return path provided back from the directional circuit to the first source for providing an alternating electric field. The directional circuit being a loop circuit which includes one or more circuit elements causing the loop circuit to be asymmetric to current flow; the directional circuit having no continuous connective path to earth ground, or battery ground, the directional circuit thereby developing a DC potential in response to the alternating electric field which is self referencing between a relatively high potential output and a relatively lower potential output. One or more loads connected to the directional circuit, the one or more loads also not having a continuous conductive path to earth ground or a battery ground. The load is not provided with a continuous connection to earth ground, or battery ground.
