The AEFC just hit another milestone. I’ve added a video to the Files section titled Coil3PulseReturns.mp4 that shows what I’m seeing. With the supercapacitor bank steady at 7.40 V DC, the staged AC pulse between Coil 3 and the negative side of the harvest capacitor has returned. I drained the caps first to see if the pulse would ever come back, and honestly I wasn’t sure it would. It did. This is no longer a single observation. After a full drain the pulse returned under the same conditions at about 7.4 V. That is the first hard evidence of a repeatable, state-dependent mode in the AEFC rather than a one-off instance. The sequence is stable and clear: about 4.69 VAC, dropping to zero, spiking to 42.2 VAC, collapsing again, then looping.

  What makes this important is that the pulse only appears once the bank has charged past a threshold. When storage is low, it vanishes. I’ve already seen it absent around 7.2 V and present again around 7.4 V. Once the bank climbs high enough, the system shifts into this mode. That suggests the AEFC isn’t just catching ambient noise. It is running with threshold dependence, with Coil 3 acting like a gate that opens and closes conduction windows in step with the bank’s charge state.

  My current interpretation is that the lower stage around 4.7 VAC is a longer-duty, smaller-amplitude portion of the cycle, while the 42 VAC stage is likely a sharp inductive collapse spike that the handheld meter reports as a high RMS value. The pauses at zero show this isn’t a smooth oscillation but a segmented cycle, which matches the idea of Coil 3 steering energy directionally and changing behavior once the bank crosses that voltage threshold.

  The key here is repeatability. After draining the caps, the staged pulse still returns on its own once the bank climbs high enough without any direct power source. That confirms the AEFC has operating modes dependent on stored energy, a major shift from the early days when it looked more like random field interactions. The circuit now shows signs of self-modulation once it has energy in reserve, and that is a big step forward.

  I’m connecting this result to my working design model I call Rhea’s Law (found on my profile page), written as P = I × E. I’m not proposing a new law of physics; I’m describing how this harvester behaves. Here E is the bias or EMF condition set by the supercap bank, I is the Coil 3 flow that only establishes once that bias crosses a gate, and P is the consequence measured as energy added to the bank. Below about 7.2 V the mode is off, and around 7.4 V it flips on and repeats. That repeatability is the proof that this isn’t an anomaly but a real operating mode, and it ties directly to the threshold-flow-consequence framework of Rhea’s Law.
