Run 1: 2026-10-04 (first run; nothing to recheck). Time-capped run: web searching and browsing took about 7.5 minutes of wall clock (started at epoch 1791148836 and stopped at about +450 s), within the 10-minute limit. Chrome was used for all searches. Downloads were done by script from URLs found in Chrome, plus Wayback Machine CDX queries.

Name note: the folder spells the name "Vlaenederen". The publications use "van Vlaenderen" (also "Koenraad J. van Vlaenderen" in 2023, and the e-mail handles kovavla, raccoon and koen@truth.myweb.nl). A Belgian chess player and a Belgian company co-founder share the name. They appear to be different people and were not investigated.

Leads for review

1. The inventor's own work

• 2016 journal paper "General Classical Electrodynamics", UJPA 10(4):128-140, DOI 10.13189/ujpa.2016.100404 (Ethergy B.V. / IBR) [web] https://www.hrpub.org/journals/article_info.php?aid=5192 ; file research/files/UJPA-2016-10-4-General-Classical-Electrodynamics.pdf. Builds the theory on "Whittaker's reciprocal force law"; says GCED is consistent only if a >> c; says the theory "has been verified by seemingly unrelated experiments". Bears on claims 3, 4, 5.
• viXra 1512.0297 (Dec 2015, 31 pp), fuller version with the "Coulomb premise" (a >> c, b = c) and the energy-conversion programme "in the footsteps of Nikola Tesla and Thomas Henry Moray" [web] https://vixra.org/abs/1512.0297 ; file downloaded. Claims 3-5.
• 2001 Hadronic Journal 24:609-628 (with A. Waser), received 13 Nov 2001; scanned copy downloaded [web] http://www.tuks.nl/pdf/Reference_Material/Waser/GeneralisationOfClassicalElectrodynamics.pdf. Origin of the S field, the LES wave, the extra force term and the energy theorems. It is the basis of the 2003 priority claim against Monstein-Wesley (EPL, 15 Aug 2002). Claims 1, 2. Needs OCR or page-image reading.
• Archived personal website (2002-2006) with the 2001 preprint "Electrodynamics with the scalar field" (Oct 2001), a 2002 conference draft, Liénard-Wiechert/Lorenz-condition notes (2001, 2003) and the author's reply to Bruhn [web] http://web.archive.org/web/2003*/home.wanadoo.nl/raccoon/* ; 7 files in research/files/wayback-raccoon-*. The 2001 preprint states "A single point charge cannot be a source for the scalar field, because the scalar field that is derived from the Liénard-Wiechert potentials is zero" [read]. This bears on where S can come from (claims 1-2). The 2002 page frames the work as explaining Tesla waves and "overunity devices" that "have been kept a secret" [read]. Claim 5 motivation.
• SEM2023 lecture, Prague (YouTube, NAMI-Tech, 2023-10-11, 48.6 min, plus Q&A): "Scalar field theory and technologies", on "devices like Moray's radiant energy power source, and possibility of constructing devices that convert scalar field into electricity" [web] https://www.youtube.com/watch?v=Egv98PRKrwc. The most recent statement found; not transcribed. Claims 2, 5.
• "General Classical Electrodynamics, part two" (ResearchGate preprint, Apr 2018) on the energy density of sources, not retrieved [web] ResearchGate profile. Claim 2.
• Also listed but not retrieved: "Electrodynamics with the scalar field", Hadronic J. 27(6):673-691 (ResearchGate listing) and as chapter 18 of a 2016 book (Google Scholar); the 2004 Rinton Press chapter in "Has the Last Word Been Said on Classical Electrodynamics?".
• The author's reply to Bruhn: "S is introduced not for mathematical reasons. S is introduced for describing new effects that are not covered by the usual Maxwell theory" [read: research/files/wayback-raccoon-refutation-Bruhn-Remark.html]. Claim 1.
• No patents by the author were found (Google Patents, inventor "vlaenderen").

2. Supporting information by others (and the evidence against, stated alongside)

• Butterworth, Allison, Cavazos and Mullen (2013), J. Sci. Exploration 27(1):13-23: the only replication found of Monstein-Wesley. They built "a duplicate of MW's apparatus". Their results "resemble MW's theoretical pattern more closely than did their own experiment", but they "dispute MW's claim on theoretical grounds, and Rębilas' ground plasma currents on experimental grounds" and conclude "a yet-unidentified mechanism must be producing the observed results" [web] https://journalofscientificexploration.org/index.php/jse/article/view/477. Claim 4 (the author reads this experiment as LEM waves).
• Ignatiev and Leus, primary text (copy from the author's site): 2.5 km wavelength, phase measured against a 0.5 km optical-fibre reference; results held across terrain and season; "as if the signal velocity was c_e = 1.12c" [read: research/files/wayback-raccoon-Art-p16.pdf]. Claim 4 (the author attributes the 0.12c to data interpretation).
• de Sangro, Finocchiaro, Patteri, Piccolo, Pizzella, "Measuring Propagation Speed of Coulomb Fields" (arXiv:1211.2913; EPJ C 2015 [memory, medium]): results "seem compatible with an electric field rigidly carried by the beam itself" [web] https://arxiv.org/abs/1211.2913. The author cites it for a >> c (claims 3-4). A published counter-reading exists [memory, low; to verify].
• Hively and Loebl 2019 (Physics Essays 32:112-126) / Reed and Hively 2020 (Symmetry 12:2110): independent extended electrodynamics with the same scalar (Lorenz-gauge expression), the same J·C force and ρC power term. They report preliminary tests in which the wave passed "through thousands of skin-depths of solid copper" [web] https://www.mdpi.com/2073-8994/12/12/2110. These are the authors' own reports; Hively is the patentee of SLW antennas (interested party). The primary test report is paywalled. Claim 2.
• Evidence against: G.W. Bruhn (TU Darmstadt), two web critiques. The author's modified sources ρ' = ρ + ε0 ∂S/∂t, J' = J - ∇S/μ0 conserve charge "if and only if" S satisfies the homogeneous wave equation; Bruhn calls this "a strong argument against the physical validity" [web] https://www2.mathematik.tu-darmstadt.de/~bruhn/vV191005.html. This is the same relation as the 2003 paper's eq. 24 (deep read); the two sides interpret it oppositely. Claims 1-2.
• Evidence against Monstein-Wesley: Bray and Britton, Comment, EPL (2004), with MW's Reply, EPL 66(1):155-156; K. Rębilas, "On the origin of 'longitudinal electrodynamic waves'" (2008), which proposes ground plasma currents. Titles only; not read. Claim 4.

3. Closely related work

• Minotti and Modanese, "Aharonov-Bohm electrodynamics" (EPJ C 83:1086 (2023); J. Phys. Commun. 8:055003 (2024); Symmetry 2023; EPJ Plus 2026; EPJ C 86:593 (2026)): mainstream-journal theory in which S = ∂_μA^μ is physical, sourced by non-conserved currents, with "gauge waves" of pure potentials and a proposed detection circuit. Both downloaded papers cite van Vlaenderen and Waser 2001 [read: reference lists] [web] https://arxiv.org/abs/2310.13968 , https://arxiv.org/abs/2403.10580. Claims 1-2, and claim 2's condition that S needs charge non-conservation.
• US 9,306,527 B1 (L.M. Hively; Gradient Dynamics LLC; filed 2015-05-29, granted 2016-04-05): antennas to transmit and receive "scalar-longitudinal waves" [web] https://patents.google.com/patent/US9306527B1/en. The patent's description of what the device does is the patentee's characterization. Claim 2.
• A.I. Arbab (Progress in Physics 2009, with Satti; EPL 2011; MPLB 2017; Optik 2017), V.M. Simulik (arXiv:1606.01738), Tomilin and Panchelyuga (Metaphysics, RUDN, 2025, in Russian, with an experiment review) [web] Google Scholar citing list; https://journals.rudn.ru/metaphysics/article/view/49179. Claims 1-2, 4.
• Experiments the 2016 paper adds for the longitudinal Ampère force (claim 3): Saumont, Phys. Lett. A 165 (1992) 307-313; L. Johansson, Lund 1996; Marinov motor as observed by T.E. Phipps Jr.; G. Nikolaev [read: research/files/UJPA-2016..., Section 4.2]. Not yet looked up.

4. Historical record

• Ethergy B.V., KvK 59508701, active, head office Amsterdam [web] https://opencorporates.com/companies/nl/59508701. The author's 2016-2018 papers give "Ethergy B.V, Research", Alkmaar; ResearchGate says "Theoretical research at Ethergy B.V." No patents or products found. Under "absence of evidence": a commercial R&D affiliation for scalar-field energy conversion with no visible output. Explanations to weigh: a one-person consulting or holding B.V.; trade secrecy; no device stage reached. Records that would decide: the KvK extract (founding date, SBI code), filed annual accounts, Espacenet with Ethergy as applicant, and the 2023 lecture.
• Institute for Basic Research, Palm Harbor FL, and Hadronic Press: publisher of the 2001 paper and the author's affiliation from 1999 to 2018 (the 2018 paper says "Associate professor"). IBR is R.M. Santilli's institute [memory, high]. That affiliation and the venue are context for how the 2001 work was refereed.
• Publication path: arXiv (1999, 2003), then Hadronic Journal (2001, 2004), Rinton Press (2004), viXra (2015), HRPUB (2016), ResearchGate (2018), conference lecture (2023). No arXiv submissions after 2003 were found. Whether arXiv refused later work is unknown; the record shows only the move to viXra.
• Priority dispute: the Hadronic paper was received 13 Nov 2001 [read: page image p.1]; Monstein-Wesley published 15 Aug 2002 [web]. Monstein-Wesley's submission date and their own position were not checked. Claim-2 priority note in claims.md.
• Search-engine removal: Google showed a legal-request removal notice (2 results) on a Moray/Fletcher affidavit query. The removed items are unknown; check LumenDatabase.org next run before drawing anything from it.
