Findings (witness accounts, ESTC July 2016)
- Mark McKay, PE ("Spokane1"), post #1-2, 11 Jul 2016. He describes himself as a classical EE and says he has known Gunderson about 10 years, living in the same city. He helped carry in the setup and sat in the front row. His account [web]:
- Measurement: two power analyzers (input and output) plus "A Tektronix (2000) 4 channel scope with advanced math functions"; "Both sets of instruments agreed".
- Readings: "1.53 watts in and 9.43 watts out or a initial COP of 6.16". The load was a 12 V automotive lamp. "an hour later the input wattage was down to zero (with four places of accuracy) with the output still at 9.5". Gunderson "reported that he has observed the input value go negative like -.25 watts in."
- "If the instrumentation is correct he should be able to loop the system and have a self runner, but he ran out of time." The device became operational 6 Jul 2016, and Gunderson "submitted a provisional patent" that weekend.
- The 2015 ESTC device had a COP of about 1.02 (McKay was hoping for 1.05).
- Construction: a 12.7 Ah gel battery feeds an H-bridge, then a step-up transformer at about 800 V peak, then a custom transformer of two dissimilar ferrite C-cores (one high-permeability, one lower), "beefed up with about 20 Manganese Ferrite PM's (2" x 3" x 0.5")". The secondary is #10 AWG Litz, with a SiC-FET synchronous rectifier and a 0.010" Mylar gap. Operation is around 50 kHz. McKay compares it with E.V. Gray.
- Gunderson's idea came the previous November, from parts of "a two year old failed experiment".
- "Reiyuki", posts #4, #6, #8, #13, #15 [web]. He documented the device at the conference and posted photos.
- Input: a resonant H-bridge charge pump at 200-300 V in "push-pull-sleep" (about 33/33/33). Output: a synchronous rectifier opened briefly near the phase transition, with a 1-2 kV spike.
- Operating band 20-50 kHz with 5-10 W out. Magnets bias the primary ferrite to the "knee".
- His recollection of the phase-tuning table: 110 deg gives 4 W in and 8 W out; 140 deg gives -1 W in and 3 W out. The demo was about 3.5 W in and 8.5 W out.
- "If you ask Graham, he will say outright he doesn't know why it works." He compares the device with the Russian TK/Kapanadze/Akula circuits.
- Page 5 (to Oct 2016): circuit variants (H-bridge logic by Spokane1, 19 Sep 2016), cross-links to overunityresearch.com threads, and "Musings on the energy source" by Cyril Smith ("Smudge"). No completed replication with measured result was seen on pages 1 and 5. Pages 2-4 were not read.
- The rexresearch compilation quotes another forum report on Gunderson's 2015 transformer: "he's using phase to rotate flux along the gap under resonance and harnessing power from this virtual rotation", driven by one AC amplifier and a function generator, 20-200 kHz, and "only COP 1.03" [web] http://www.rexresearch.com/gunderson/gunderson.htm
Bearing on the claims
- Priority 2 (witness accounts). McKay is an independent engineer and a friend, not a commercial party, writing on the forum of the conference organiser.
- The readings are instrument readings reported second-hand. No independent replication has been found.
- The phase-dependent "input goes to zero or negative" reports parallel US 7,830,065 [0044] ("absence of electrical loading at the input and/or an overall amplification of the input signal") [read: claims.md claim 2].
