This suggestion applies to the older simulations...

The battery, in the Ammann brothers' circuit to which I
have contributed my speculation as to revealing its
mystery, could be replaced with a micro mini solar panel
plus a voltage divider to discard the excess voltage and
keep its contribution to this circuit reduced to a mere
micro volt at all times to insure overunity will result.

The following idea comes from the latest version...

ammann-brothers_PRECHARGED-CAPACITOR+PLUS-NEGRES-COILS

Possibly the insulation on the three coils is made of
a special material that induces a mild negative resistance?
Maybe it has bismuth laced inside of it?

The windings are spaced to induce capacitance equal to
three fourths of their inductance.
