In the core of this outer toroidal coil is the instrument package. The system pulses with a DC component. Tuning is a function of the coil mass and cross-sectional aspect ratio. It appears an elliptical cross-section is required in the coil. Over Unity, solid state electrical output for lighting, no apparent input, appears toroidal in geometry or similar to a Hendershot Generator, will not demonstrate device running motors.
