e electrical energy from an independent source, controlling the charging of said device by the action of the effects or disturbances, and coincidently using the stored electri cal energy, for operating a receiving device. "3. The method hereinbefore described of utilizing effects or disturbances transmitted through the natural media, which consists in controlling, by means of such effect or disturbances, the charging of an electrical storage device from an independent source and discharging the stored energy through a receiving circuit.
