To those of you who have reached resonance (or are close), we propose to add feedback coils on top of both secondary coils, in an experiment to transfer energy back and forth between the primary and secondary windings. With reference to Tesla’s work, we would expect to see several effects realized:

1. Since the energy stored in the resonant LC tank circuit is normally supplied to the output coils (and load) during the period when the rotor is between poles (primary voltage at zero crossing), we see a path where the addition of feedback coils will serve to transfer energy (real power) back to the primary during the output interval, effectively inducing a second voltage peak halfway between the normal primary voltage peaks....
