Title: POWER RECEIVER INCLUDING FARADAY CAGE FOR EXTRACTING FROM ELECTRIC FIELD ENERGY IN THE EARTH
Abstract:
A circuit is operative to extract electromagnetic wave energy from the ground via a resonant transformer in which resonance is triggered by electrical charge arcing across a spark gap. A center tap of the primary winding of the transformer is capacitively coupled to an electrode buried in the ground. In-rush current from the ground electrode is converted to a useful form (e.g., one- or three-phase 60 Hz AC) by a power conversion circuit connected to the secondary winding of the resonant transformer. The ground electrode of the capacitor coupling the grounded electrode to the center tap primary winding is the shield of a Faraday cage enclosing the resonant transformer, spark gap, and a high-voltage power supply exciting the spark gap.
