Hi everyone, I am new to this forum, and I am old thinker of free energy
I think the one problem is in the diode nte125, I think it should be reversed like in original Peter's schematic.
In your schematic 12v battery is constantly running the coil and when photo transistor opens, 2n3055 also opens, so the PSU is running the current through the coil and through the battery. The battery could never be charged this way. It's like when you are charging the car battery with reversed polarity it is more like quick DIScharge rather than charge.
