Central claims: Sykes-Chris
Source: one document, Chris Sykes, "Guidelines to Bucking Coils: Lenz's Law Free Power Extraction", v2.7 (26.02.16), 49 pages. Read by digest plus deep reads from the text layer and page images (pp.4-19, 21-42, 25-31, 34-39). Pages 45-49 were read from the text layer, with p.45 and p.48 checked as page images; they hold no photographs or numbers. The text layer is available (3 pages OCR'd). No Source gap. Linked videos, the scans of Sweet's lab notes and Itsu's replication data were not seen. The document contains no power-in/power-out table for any device Sykes built; the only quantitative measurements by Sykes are the coil traces on pp.14-16. Every other power figure comes from outside the document (Sweet's 1986 lab-note transcription, Bearden, forum posts).
- Two partnered output coils wound in opposite directions (or wired to oppose), with correct geometry and half the conductors seeing the opposite field change, cancel the magnetic component of the output while the electric (A vector potential) component adds, which removes Lenz-law drag on the input. Sykes adds a design rule: these devices work best with a step-up ratio (1:3 "common", Sweet 1:5), and "Current, as you may think, is not stepped down as a result of the Voltage being stepped up" (p.11), although p.10 gives the ideal-transformer rule correctly (I2 = I1 N1/N2).
- Lenz's law is the result of drawing current from already-separated charge, not its cause, so charge separation (the "generator" action) can occur without a reflected magnetic field. His one experiment for this is a single sentence (p.45): a permanent-magnet rotor spun past one bobbin of partnered output coils gave "No or next to no Lenz's Law" while electricity was generated; no setup, speed, load or numbers.
- The magnetic field itself slows charge flow; the author's filar versus non-inductive bifilar comparison (about 650 microseconds versus about 75 ms at 7.8 ohm) is offered as proof. The two times are not cursor-measured charge times (75 ms is about 3 L/R of the filar coil; 650 us is about the generator's pulse width).
- The effect needs loose coupling (gapped core; his only evidence is an informal, unquantified rebuild with a tight core that he "was not able to make ... work the same", pp.31-32), a Bloch wall between the bucking coils, a diode with a square-wave or pulsed drive operating at the BH-curve knee (prose only, p.42, "work in progress"; the circuit he prescribes on p.38 is a sine drive with no diode), a suitable load (Walt Rosenthal: the VTA "likes" at least 25 W, p.46) and, in his experience, a resonated LC-tank input (p.24). With these he says input power falls as output rises because output current fed back raises the input coil's impedance (p.46). His alternator test is a motor-driven automotive alternator whose field coil is connected in a short circuit or in series with the output coils so it gives output with "no further Input" to the field. He writes "Not Free Energy", and that "ONLY because of Lenz Law, Resistive Mechanical Force is applied on the Shaft" (p.48); the shaft input remains.
- Floyd Sweet's VTA and the devices of Moray, Meyer, Jensen, Koenig, Markov, Frolov, Melnichenko, Mishail1971, Utkin, Bill Alek (SmartPAK), Hendershot, Kromrey and Figuera work on this one principle, which the author ties to Bearden's wave/anti-wave and zero-vector language, and to Sweet's "self-oscillation" in transformers (Manning and Bearden quotations, p.12). The survey (pp.25-31) is by drawing resemblance; no device in it comes with a power measurement, apart from the SmartPAK diagram caption "EFFICIENCY >> 100%" (no numbers) and Sweet's 1986 lab notes (transcribed, with a 1 mW and a 0.023 mW input stated for different runs, a line-powered generator, and a part Sweet withheld) and claims reported from others (Sykes's "5000 W" generation-six VTA, p.13, no source; Bearden's 6 W).
- Generators are "98-99% efficient" (p.23): Sykes reads this as 100% of shaft energy with 1-2% lost, and labels the other 98-99% (the converted useful work) as Lenz drag, so removing drag is, in his view, the route to higher efficiency. The author says elsewhere that this is not a new energy form (pp.47-48) and also that the system is an open one connected to the Aether and that "Free Energy Future is here NOW".
