Leads for review

1. The inventor's own work

• US 7,830,065 B2 (granted 9 Nov 2010) is the grant of US 2006/0163971 [web] https://patents.google.com/patent/US7830065B2/en
• The granted description adds "believed to". It removes "without consuming natural resources", "persists until the magnets are no longer magnetized" and "reduction of required input power as loads are applied".
• It keeps [0044] (input unloading or amplification; less input as more output is withdrawn; magnets work "until they are demagnetized") and [0040] (unquantified "Experiments show ...").
• Granted claim 1 adds a resonant circuit with a square-wave source. New claim 11 recites the FIG. 1-3 geometry and "improves the efficiency".
• Bears on claims 1-2 and the FIG. 4 resonant drive.
• ESTC 2015 "Overunity Disclosure" (94 min + 36-min schematic video) and "Floyd Sweet's VTA" (59 min) [web] https://emediapress.com/shop/overunity-disclosure/
• A solid-state transformer with a "motional" field, "barely overunity". The 2015 device COP is reported as about 1.02-1.03 by forum attendees [web] (energeticforum, rexresearch).
• Same principle as claim 1, "virtual motion".
• ESTC 2016 "Magnetic Implosion Transformer" (103 min) [web] https://emediapress.com/shop/magnetic-implosion-transformer/
• Gunderson's own words: a lamp "drawing 570% more energy than could be accounted for going into the input"; input can be dialled to zero; "still in the process of validating"; "not quite sure why it works".
• Magnets with "compression" and "spark" cycles. A provisional was reportedly filed in July 2016.
• Bears on claim 2: the input unloads as the output is drawn.
• grahamgunderson.com/ou (2018) [web] https://web.archive.org/web/20180115005940/http://grahamgunderson.com/ou
• About 20 years of Floyd Sweet VTA study. "Barium Ferrite magnets can be programmed to resonate"; "a magnet whose field can move, even though the magnet stays still ... [force] taken from the ambient energy".
• Here the inventor names ambient energy as the source, where the 2006 patent named the magnets. That is a change of stated energy source to put to the reviewers (claim 2).
• Later items to check: YouTube "Graham Gunderson Free Energy - Magnetic Implosion ..." (2019, own channel); LinkedIn "Infrared solar" (about 2025).

2. Supporting information by others

• Mark McKay, PE (Spokane), eyewitness at ESTC 2016 [web] https://www.energeticforum.com/forum/energetic-forum-discussion/renewable-energy/13945-magnetic-implosion-transformer-replication
• Two power analyzers plus a Tektronix scope "agreed": 1.53 W in and 9.43 W out (COP 6.16); after an hour, input 0 W and output 9.5 W.
• He is a friend of about 10 years and not a commercial party. No independent replication had been found as of Oct 2016.
• Bears on claim 2 (the Lenz-aided input).
• "Reiyuki" attended and photographed the device. Reported COP depends on the phase of the output interruption; the demo was about 3.5 W in and 8.5 W out [web] (same thread).
• Interested-party claims (assignee): MPI "POWERGENIE" report, 24 Apr 2008 [web] https://web.archive.org/web/20080514005109/http://www.magneticpowerinc.com/pdf/POWERGENIE_Technical-progress.pdf
• 2007 "Proof-of-Concept prototypes"; generation "without damping or counter-force"; "reaction-less behavior ... soundly demonstrated".
• Chava website, as quoted on rexresearch: "An early prototype produced an output, at a very low power level, of more than 100 times the input" [web] http://www.rexresearch.com/gunderson/gunderson.htm
• No data has been found. Bears on claims 2-3.
• Gunderson's own report that, as a paid verifier, he found one system "verifiably overunity": a Floyd-Sweet-VTA-like device that charged an EV battery bank in a week [web] (emediapress). Unnamed and undated.

3. Closely related work

• Floyd Sweet's Vacuum Triode Amplifier (VTA) and conditioned barium-ferrite magnets: the inventor names this as the root of his "motional field" principle (claim 1).
• Motionless Electromagnetic Generator (MEG), US 6,362,718. Google lists it as a "similar document" to US 7,830,065. It also uses permanent-magnet flux switched in a core.
• E.V. Gray: McKay compares it with the 2016 device. Russian TK/Kapanadze/Akula circuits are compared by Reiyuki.
• Mainstream magnetostrictive and magnetoelastic energy harvesting citing US 8,093,869: US DOE US9960341B1, Oscilla Power WO2015116275, Tokai Rubber (Sumitomo Riko) WO2014119202, Mitsumi WO2015002069. Also Tae Chang N.E.T. "Sound wave resonance generator" (priority 3 Dec 2008). Bears on claims 3-6 and the Step 2 prior-art comparison.
• Patents citing 7,830,065: Lovshin, Earth-magnetic-field energy (compare granted claim 8); Southeast University "time-varying magductance" generator (2022); Shaikh GB2446656A.

4. Historical record

• Assignment chain [web]: Gunderson to Magnetic Power Inc. (CA, 2006); MPI to Chava LLC (FL, 2010); then Chava Energy LLC (FL, 2015); Chava Energy LLC (NV) to Chava Energy LLC (FL, 2018).
• 7,830,065 lapsed (12th-year fee unpaid, effective 9 Nov 2022). 8,093,869 fees were paid late in 2019; adjusted expiration 2029.
• MPI's founder was Mark Goldes (Aesop Institute). MPI and Chava framed the patents as zero-point-energy "GENIE/POWERGENIE" and "MagGen" generators [web] (naturalphilosophy wiki; Wayback MPI; rexresearch).
• An anonymous critic ("Physics Review Board") calls Chava's MagGen solicitations fraud. That is a critic's characterization; no court finding was found.
• Absence-of-evidence anomaly. Chava announced "several prototypes of more advanced devices", "an additional, very broad, patent application" and 30 more patents in 3 years. Gunderson filed a provisional in July 2016. Yet no further published patent family exists for Gunderson or Chava (Google Patents), and no prototype data, papers or independent tests have been found. Competing explanations:
• (a) the effects did not survive validation;
• (b) the provisionals were allowed to lapse for cost reasons (Gunderson describes building at night after a full-time job);
• (c) trade secrecy under NDA (MPI offered NDAs);
• (d) loss of funding or internal conflict at Chava (a commenter says Goldes was "ejected" from Chava);
• (e) suppression. No evidence for or against this was found.
• Records that would decide it: USPTO file wrappers, unpublished-application status, Chava corporate filings (FL/NV), SEC/DFPI records, and Gunderson's 2019 video.
• 2009 FOIA request "Busheme, Diana - Magnetic Power Inc" (probably SEC) [web] (yumpu snippet of a Black Vault log). The agency and its holdings need to be identified.
