Sigma-Ro: Arbiter (Step 3)

Project: Ether-Technology: A Rational Approach to Gravity Control (1977, 108 pp.) by "Rho Sigma", identified as Rolf Schaffranke by advocacy and popular sources (Chappell wiki, Davidson 1989, Bergier 1978) [web: see sites.md]. Inputs weighed: facts.json, claims.md, physicist.md, mathematician.md, contrarian.md, deep/ read of pp.72-83, sites.md and research/ notes.

Tags: [read] from the book or Investigator-saved files as reported by the reviewers; [web] with URL; [memory] with confidence; [calc] my own recomputation (project venv, numpy). I did not re-read the book pages myself; I rely on the three reviewers' quotations, which agree with one another on every quoted passage.

Source gap note

The book text is fully readable, so there is no gap in the project document. There is a gap in the documents the book relays: the folder holds no text by Searl, no original Barret Report, no Brown lab notes, no Saxl paper, no Cain or Roos publication, and no Seike gravity book. Every verdict about what Searl, Brown (vacuum) and Roos "did" or "reported" rests on the book's relay of those items. The Investigator's downloads (Seike 1966, 1982, 1984 JPS abstracts; Hooper patent; NEN 1993 article) are primary for what they cover. Where a verdict below rests on [memory] alone, it says so.

How to read the verdicts

The book is a compilation of second-hand letters and reports, with almost no equations. So "has it been tested?" must be asked source by source: Brown (patents, real later tests), Saxl (one peer-reviewed paper, two later null repeats), Seike (real conference abstracts with numbers), Searl (no document by Searl, no measurement, no named witness). Interested parties are named: Brown, Saxl, Seike and Searl's associates report their own or their friend's work; the Southern Electricity Board, if it prosecuted, was an interested party; Roos led a body promoting pushing gravity.

Recomputations where reviewers differed or I could check

All [calc], numpy, r = 0.4572 m (3 ft diameter), m_e = 9.109e-31 kg, e = 1.602e-19 C, eps0 = 8.854e-12 F/m.

1. Stewart-Tolman voltage V = m_e w^2 r^2 / (2e) (hub-to-rim voltage from electron inertia): 6.5e-9 V at 1,000 rpm; 5.9e-8 V at 3,000 rpm; 6.5e-7 V at 10,000 rpm; 6.5e-5 V at 100,000 rpm (rim speed 4,800 m/s). All three reviewers agree. Gap to the book's 1e5 V: 13.2, 12.2 and 11.2 orders of magnitude (1,000, 3,000, 10,000 rpm). The physicist's "at least 11" and the mathematician's "11 to 13" are both right; the deep read's "12 or more" was slightly loose. Speed needed for 1e5 V from this mechanism alone: w = 4.1e8 rad/s = 3.9e9 rpm, rim speed 1.9e8 m/s = 0.63 c. (Mathematician and contrarian both right.)
2. Charged sphere Q = 4 pi eps0 r V, surface field E = V/r, stored energy QV/2: 1e5 V gives Q = 5.1 microcoulombs, E = 2.2e5 V/m (0.07 of the ~3e6 V/m air breakdown), 0.25 J; 1e9 V gives 0.051 C, 2.2e9 V/m; 1e13 V gives 509 C, 2.2e13 V/m, 2.5e15 J (about 600 kilotons of TNT at 4.2e9 J/ton [memory, high]), Maxwell stress eps0 E^2/2 = 2.1e15 Pa (steel tensile strength is about 1e9 Pa [memory, high]); 1e14 V gives 5,087 C. Reviewers agree. So 1e5 V on a body this size is electrically ordinary (small Van de Graaff level); the failure at 1e5 V is the mechanism, not the magnitude.
3. Unipolar induction in Earth's field (Davidson's alternative reading of Searl's small 1950 EMF), V = (1/2) B w r^2 with B = 5e-5 T: 5.5e-4 V at 1,000 rpm. Physicist 5.5e-4 V, mathematician 3.3e-4 V at 10 rev/s (600 rpm; their inputs differ, both consistent with my formula). A real, millivolt-scale or smaller effect, not 1e5 V.
4. Power and flux: 1e13 W from a 2.6 m^2 sphere is 3.8e12 W/m^2, 6e4 times the Sun's surface flux (6.4e7 W/m^2 [memory, high]); 1e15 W is 53 to 55 times world average primary power (about 1.8-1.9e13 W [memory, medium]) and about 0.6% of all sunlight on Earth (1.7e17 W [memory, high]). All three reviewers' figures check.
5. Seike's Frenkel-Kramers equations as written (real vectors K, J; dK/dt = a(K x H - J x E), dJ/dt = a(K x E - J x H)), integrated with fourth-order Runge-Kutta. Reviewers disagreed: the physicist said the closed system "has no exponential growth at resonance" and has bounded precession; the mathematician said static E alone gives hyperbolic growth. - H only: |K| = 1.000 and |J| = 0.500 conserved (pure rotation). Larmor precession. - Static E only (E along z, K = (1,0,0), J = (0,0.5,0), a = 1, t = 2): |K| grows to 1.949 and |J| to 1.746; K.K - J.J stays 0.75. Analytically K_x = cosh t - 0.5 sinh t, which gives 1.949 at t = 2. - The mathematician is right for the equations as written with real K and J; the physicist's statement is wrong for that case. However the abstract says J is "polar angular momentum" defined with an i (iJ_1 = x4 p1 - x1 p4 + ...), and says the solution precesses about H + iE; with J imaginary the E-only case becomes a rotation. So whether growth or precession is intended is a convention question I cannot settle from a one-page handwritten abstract (the mathematician says the same). Either way both reviewers and the contrarian agree on what matters: there is no gravitational term in the equations.
6. Seike 1984 coil data (2-6 A; -0.059, -0.123, -0.169, -0.213, -0.291 g; coil about 30 g): - Straight line: slope 0.0554 g/A, intercept -0.0506 g, residuals up to 0.013 g. Through the origin: 0.0442 g/A. Quadratic: 0.00186 I^2 + 0.0405 I - 0.0246. Power-law fit: weight loss proportional to I^1.40. - Ratios weight loss / I: 0.030, 0.041, 0.042, 0.043, 0.049 g/A (rising); weight loss / I^2: 0.0148 to 0.0081 g/A^2 (falling). So it is neither proportional to I nor to I^2; the exponent is in between. - Zero weight: the fitted line (with intercept) reaches 30 g at about 542 A; scaling the 6 A point linearly gives 619 A (Seike states about 620 A). The contrarian's "about 540 A" and the mathematician's "620 is the 6 A point scaled" are both correct. - Mathematician and contrarian differ on interpretation: the mathematician says "close to linear, so a magnetic artifact is the expected signature rather than heating (I^2)"; the contrarian says it "fits neither". My exponent of 1.4 supports the contrarian: this five-point set cannot discriminate between a magnetic-force artifact (about I) and a heating artifact (about I^2), nor identify a mixture. The nonzero intercept of -0.05 g at 0 A is a baseline problem under either reading. The physicist's Earth-field Lorentz estimate (0.05 g at 6 A) and the mathematician's stray-gradient estimate (about 2 g) use assumed inputs and give very different answers; a closed loop in a uniform field has zero net force (physicist), so the gradient route is the relevant one. The honest conclusion is "an artifact of the right size is easy to imagine; none is demonstrated".
7. Sink-flow force scaling (mathematician): for an inviscid sink flow u = Q/(4 pi R^2), u^2 scales as R^-4 and the pressure-gradient force on a small body scales as d(u^2)/dR, i.e. R^-5 (checked by differentiation). The coefficient depends on body shape and added-mass effects, but the R^-5 scaling does not. A 1/R^2 force needs a drag proportional to u, which needs viscosity, which Roos explicitly denies (he calls the ether non-viscous and invokes the no-force-in-parallel-flow result, d'Alembert's paradox [memory, high]). I accept this as a real internal inconsistency in the book's stated premises.
8. Saxl: torsion-pendulum period T = 2 pi sqrt(I/kappa) does not contain g (I = moment of inertia, kappa = torsion constant). The book's inference (p.52) that a period change shows gravity varies is therefore not supported by the apparatus type. The physicist did not catch this; the mathematician did; I adopt it.
9. Brown's numbers: 100 kilodynes = 1.0 N on about 10 kg (98 N weight) is 1.0%; the book's own source (Brown's letter) says none of the units ever floated, and the "110 percent" 15-inch dome was tethered by wires to the high-voltage equipment. Consistent across reviewers.

Web verification (budget 8; used 7)

Medium/low-confidence [memory] facts that verdicts depend on, retagged:

1. Bahder and Fazi (US Army Research Laboratory), arXiv physics/0211001 [web: https://arxiv.org/abs/physics/0211001]: "ionic wind is at least three orders of magnitude too small to explain the magnitude of the observed force on the capacitor"; ionic drift "leads to the correct order of magnitude"; they note they cannot yet fit drift into a theoretical model and call for vacuum experiments. The contrarian cited this from a search summary; confirmed. The physicist's plain "ion wind explains it" omits it. The authors' own conclusion still locates the force in ionic transport (drift), not in gravity, and they leave the mechanism unexplained.
2. Talley (1988), Tajmar (2004) [web: https://en.wikipedia.org/wiki/Biefeld%E2%80%93Brown_effect]: Talley "measured no thrust from electrodes similar to those proposed by Brown operating in 10^-6 torr vacuum under direct current potentials. He did find a force during electrical breakdown when current was flowing." Tajmar enclosed the apparatus in a suspended box and observed no linear thrust. This is a secondary (Wikipedia) summary; the primary papers were not opened by me or the contrarian. Tajmar's abstract was quoted by the physicist [web: https://publications.ait.ac.at/en/publications/the-biefeld-brown-effect-missinterpretation-of-corona-wind-phenom].
3. Saxl repeats [web: https://cpl.iphy.ac.cn/article/id/35374 and ResearchGate listing; search summary]: Li Jianguo, Fan Shuhua, Zhang Xuerong, Luo Jun, Chinese Physics Letters 9, 117 (1992), "Electrically Charged Torque Pendulum Experiment with a Null Result": repeated Saxl's experiment "with an accuracy about one order higher", found no anomalous period change, and suggested Saxl's result could be explained by capacitance between the pendulum disk and other apparatus parts. This resolves the reviewers' split (physicist: no replication found; mathematician: null by title only; contrarian: null unverified). Based on the abstract as returned by search, not the full paper.
4. Second Saxl repeat [web: https://ui.adsabs.harvard.edu/abs/1998PhLA..244....1L/abstract]: Liu et al., "Test of Saxl's effect: No evidence for new interactions", Physics Letters A, 1998: precision two orders higher than Saxl; electrostatic forces shifted the pendulum's equilibrium position; effect is mechanical, not a new interaction. No reviewer found this one. Abstract-level only.
5. Searl legal record [web, partial, low reliability]: a search summary of the Kook Science wiki page (https://hatch.kookscience.com/wiki/John_Searl; the page itself would not load, self-signed certificate) states that a man who attacked electricity pylons, causing about 7,000 pounds of damage and nearly blacking out a large part of southern England, was jailed for 15 months at Reading Crown Court, reported in the Evening Post on 5 January 1983, and ties this to Searl. I did not open the underlying newspaper item. Kook Science is a sceptical wiki, so this is an interested characterisation; the Evening Post report, if it exists, is the primary record. Wikipedia's "Abstracting electricity" article does not mention Searl [web: https://en.wikipedia.org/wiki/Abstracting_electricity]. See the absence-of-evidence section.
6. Hathaway and Williams (arXiv:2103.00700): abstract confirmed by the mathematician; I did not re-fetch.
7. Not rechecked (verdict-neutral): Christenson and Moller 1967 ion-wind paper; Eot-Wash and MICROSCOPE equivalence-principle limits; Herrmann et al. 2009 resonator limit (10^-17) cited by the contrarian from a search summary; steel burst speed; world power. None changes a verdict because the Searl and Seike verdicts rest on arithmetic and quoted text. Confidence kept at medium for those figures.

Corrections to Step 1 (consolidated from the three reviews)

• claims.md claim 1 should not say a condenser "loses or gains weight" as Brown's own statement: the 1 percent figure comes from the book's narrator (p.34). Brown's own letter says air thrust was "largely" ion momentum transfer, that the gravitor lost weight only when its negative-to-positive thrust pointed up (a force on the apparatus), and that vacuum lab notes were never published (pp.44-45).
• Saxl's apparatus is a torque pendulum, not a simple pendulum (mathematician); the book's gravity inference does not follow.
• The 10^9 V figure is in the sub-committee report (p.87), not pp.72-83. The book gives incompatible values for the same "relatively low speed" condition: 1e5 V (p.75) versus above 1e9 V (p.87); thresholds 1e13 (p.76), 1e14 (p.73) and 1e10-1e14 (p.87).
• "Left the Earth" is the report's supposition ("is thought to have gone off into space", p.75), the 1952 test has no date, place or named witness.
• Pages, Carstoiu, DePalma are theories in the book, not built devices. Seike's own 1982 abstract contains no gravity or power figure; the NMR/ESR, Larmor-frequency and ferromagnetic/ferroelectric slips are in the book's paraphrase (pp.82-83), not shown to be Seike's. Spelling: Seike (Seike Shin'ichi), not "Seiki".
• 3x10^9 kW = 3x10^12 W (about 60 times Saturn V first-stage jet power of about 5e10 W [memory, medium]).
• Added by the QE revision (details in that section): Saxl is a "post-doctoral student" of Einstein per the book (p.50), not a colleague. The p.92 page is a figure (streamlines around a closed vortex pair, "German Research: Hypothetical configuration of a secondary gravitational field"), not garbled text. "No gravitational term" in Seike's equations holds for the 1982 and 1984 abstracts and for the Frenkel-Kramers equations of motion, but the 1966 paper I writes the spin-field energy tensor with k, "Newton's gravitational constant". "NER" first appears in the 1982 abstract; the 1966 abstracts treat the same co-precession of magnetisation and electric polarisation without the name. The suppression evidence in the book is nine incidents, not four. The book mislabels Jean Becquerel as the discoverer of radioactivity (Henri Becquerel; Jean was his son) [memory, high]. The book dates Dirac's "proof of the ether" 1954 (p.62) and 1952 (p.65).

Claim-by-claim arbitration

Claim 1: Electric fields alter gravity (Biefeld-Brown thrust, vacuum thrust, Saxl's charged pendulum)

Agreement. All three: the book has no model and no calculated expected size; Brown's own letter concedes air thrust is largely ion momentum; Brown's vacuum notes are unpublished; Hathaway and Williams 2021 is a null for static charge but does not test an asymmetric capacitor or Saxl's period; an unpublished data set cannot be reviewed.

Disagreements and how I weigh them. - Air thrust. Physicist and mathematician: ion wind, Established. Contrarian adds that the ARL calculation finds ionic wind alone three orders too small. I verified that (web check 1). Weighing: the thrust is real and reproducible; the explanation is electrical/ionic (the ARL authors themselves point to ionic drift), no gravity change is needed, and the quantitative model is still incomplete. The contrarian's point is correct and belongs in the record; it does not rescue a gravitational reading. - Vacuum thrust. Physicist: Tested, not supported (Tajmar). Mathematician: Never properly tested. Contrarian: Tested, not supported by Talley and Tajmar, but conditions are not matched to Brown's 70-220 kV at 10^-6 mm Hg. Weighing: the contrarian's caution is fair: Tajmar and Talley did not replicate Brown's exact voltage and dielectric geometry. But Talley's detail matters: force appeared during breakdown, which matches Brown's own report of thrust "bursts" at every vacuum spark, and the only unexplained part is Brown's statement that thrust persisted without sparks, for which he gives no numbers. Independent tests found nothing without breakdown; Brown's own positive vacuum results were never published as data. The record does not show the effect was dismissed untested (it was tested, at other conditions), nor that it was tested at Brown's conditions by a neutral party. - Saxl. Physicist: Never properly tested; mathematician: never tested as a gravity effect, with a null by title; contrarian: possibly Tested, not supported (unverified). Resolved by web checks 3 and 4: two independent torsion-pendulum repeats at higher precision (1992, one order better; 1998, two orders better) found no anomalous period change and attribute the original shift to electrostatic coupling (capacitance, equilibrium shift). Combined with the mathematician's point that a torque pendulum's period does not depend on g, the strong form (Saxl shows charge changes gravity) is Tested, not supported. Saxl's raw measurement is not shown to be wrong; the repeats suggest an apparatus effect. Caveat: abstracts only. - "Suppression" of Saxl ("Nutty!") is one second-hand remark in the book; he published in Nature and Phys. Rev. D, and others repeated the test in print. That is not the record of a suppressed result.

Why the stronger argument wins. The weight-change form has two independent null tests and no positive independent report; the air-thrust form has a conventional (ionic) explanation that, even by the ARL authors, is about charge transport, not gravity. The pro side's best items (Brown's lost notes; ARL's quantitative gap; breakdown-free vacuum thrust) are real unknowns but are not gravity evidence.

What would settle it. A hard-vacuum (below 1e-6 torr) torsion-balance test of a Brown-type asymmetric dielectric capacitor at 100-200 kV, shielded, with a dummy-electrode and leakage-current subtraction and sparks excluded, with the thrust compared to the measured current times gap over ion mobility. Or recovery of Brown's film and lab notes (Bahnson papers, GE archive). For Saxl, read the 1992 and 1998 papers in full and run a charged torsion pendulum inside a grounded shield with the cage-to-fibre capacitance measured.

Final verdict (split). - Thrust on an asymmetric high-voltage capacitor in air: Established (as an electrohydrodynamic/ionic effect; the exact quantitative model is unsettled, ARL). - Thrust in vacuum from a non-ionic gravity-type mechanism: Tested, not supported (Talley 1988, Tajmar 2004, at conditions not matched to Brown); Brown's own positive vacuum data never published and not independently reviewed. Not a case of dismissal without testing. - Static charge changes the weight of a body: Tested, not supported (Hathaway and Williams 2021, 2 g on 1 kg; ~0.2% sensitivity, so effects below that are not excluded). - Saxl's charge-sign dependent period as gravity: Tested, not supported (two repeats, mechanical explanation); the book's inference from a torque pendulum to gravity is Internally inconsistent. - Brown's solar/sidereal/lunar variations: Never properly tested (records unpublished).

Claim 2: An ether exists; Michelson-Morley did not disprove it; gravity is an ether sink or push flow

Agreement. All three: Michelson-Morley alone does not disprove every ether (Lorentz's ether theory is empirically equivalent to special relativity); a dragged or co-moving mechanical ether conflicts with stellar aberration and the Fizeau experiment; the book gives no equations; Roos's "proof" from the 1952 lift-off is circular; Le Sage-type pushing gravity faces the drag and heating objections [memory, high].

Disagreement. Physicist and contrarian: gravity-flow "Not testable as stated". Mathematician: "Internally inconsistent". My recomputation (item 7) supports the mathematician for the specific premises Roos states (non-viscous medium, 1/r^2 force). I give a split: Internally inconsistent as Roos states it; Not testable as stated otherwise. The contrarian's observation that an ether with no effect on light is not the book's ether, and the physicist's observation that Dirac's and Einstein's "ether" are field/vacuum concepts with no rest frame, are both kept: the position "a medium may exist" is not refuted, but it carries no weight in the book's argument.

What would settle it. For the detectable-ether form it is already settled to the tested precision (modern optical-resonator limits at the 1e-17 level [memory, medium; contrarian cites Herrmann et al. 2009 via search summary; not rechecked by me]). For the gravity-flow form: any quantitative prediction (force law, drag on planets, orbital heating) from Hilgenberg 1931 or Schappeller (both unread by anyone in this project).

Final verdict (split). - A detectable ether wind or Earth-dragged mechanical ether: Tested, not supported. - "Michelson-Morley did not disprove every ether": true as logic; Historically superseded but instructive. - Gravity as an ether sink flow as Roos states it: Internally inconsistent; as a general idea of controllable ether flow, Not testable as stated.

Claim 3: Searl's ring generator produces 1e5, 1e9, 1e13-1e14 V by centrifugal electron displacement plus coil feedback

Agreement. All three: the stated mechanism gives 1e-9 to 1e-5 V at plausible speeds (item 1); no rpm, ring count, circuit or measurement is given; 1e5 V is "indicated by static effects" (crackling, ozone), not metered; coil feedback is not quantified and cannot make an electrostatic potential 11-13 orders larger from a nanovolt seed without a stated energy source; 1e13 V on a 3 ft body implies 509 C and 2.5e15 J (items 2); the "vacuum sheath" has no geometry (the mathematician adds that the ionised region would extend about 12 m at 1e9 V and about 1.2 km at 1e13 V, not "some feet"; the formula sqrt(Q/(4 pi eps0 x 3e6)) reproduces this). Davidson's alternative reading (Earth-field induction) gives a real but small emf.

Disagreement. Only wording: the contrarian leaves room for "unspecified coil feedback", rated Not testable as stated; the physicist and mathematician say it cannot rescue the arithmetic. I side with the latter: a self-excited loop can grow current or flux, bounded by its power input, and the book states no gain or supply. The mathematician's extra point, that the book's own figures conflict (1e5 vs above 1e9 V at "low speed"), stands and is adopted.

What would settle it. Spin a metre-scale conducting disc or ring at stated rpm and read the hub-to-rim voltage with an electrometer and a shielded loop; the centrifugal prediction (about 1e-8 V) is a clean pass/fail, and any reading orders of magnitude above the induction estimate would need explanation. Or obtain the original Barret Report with dates, rpm and instruments.

Final verdict (split). - Centrifugal electron displacement plus coil feedback as the source of 1e9-1e14 V: Refuted by calculation (Stewart-Tolman 11-13 orders short; 1e13 V stress exceeds steel by six orders). - The quoted figures as a set: Internally inconsistent (1e5 vs above 1e9 V at low speed; three different thresholds). - 1e5 V on a 3 ft body from some source: Plausible, untested (electrically ordinary; never metered). - The weak form (a spinning conductor shows a small emf and static effects): Plausible, untested; ordinary induction/electrostatics.

Claim 4: Weightless and inertia-free above a threshold, output greater than input, 1952 lift-off to 50 ft and loss to space, further craft to 30 ft

Agreement. All three: no energy balance is given; output 1e13-1e15 W would be 0.5-55 times world power from a 3 ft rotor (item 4); the book's "pink halo" and ozone smell contradict such output; "inertia-free" conflicts with "impulse = recoil", a speed limit "below c" (p.78) and the editor's footnote on faster-than-light flight; the 1952 event is undated, unlocated, with one unnamed witness ("a friend"); "thought to have gone off into space" is a supposition; radios switching on is what strong radio-frequency noise from corona or arcing would do; the later craft and photos (p.74, undated, uncredited) are not evidence of flight.

Disagreement. The physicist assigns "Refuted by calculation" to the energy part and "Never properly tested" to the anecdote; the mathematician and contrarian add "Internally inconsistent". I accept all three labels for different parts. Note the honest limit: "refuted by calculation" applies to over-unity because energy conservation is applied to the claimed output; it does not refute that a rotating charged device, if one existed, lifted a few metres on some mundane ground (aerodynamic or electrostatic), which is why the event is kept separate.

Legal and suppression sub-claim (p.108). See the next section. The book says (second-hand letter of 11 Dec 1984, hedged "allegedly") that inspectors raided Searl's house in May 1982, took a "domestic type free-energy generator", the Southern Electricity Board prosecuted him for "stealing electricity", he was detained about a year, an arsonist destroyed records, and he lives under an assumed name.

What would settle it. A metered, third-party measurement of any Searl-type device's input and output; for the 1952 event, a dated independent witness or the original Barret Report; for the legal event, the Reading Crown Court record and the Evening Post, 1982-83 (Berkshire Record Office, British Newspaper Archive).

Final verdict (split). - Output exceeding input (1e13-1e15 W): Refuted by calculation (energy conservation; no source named beyond "the ether"). - Weightless and inertia-free above a threshold: Never properly tested (no measured data, no device specification); statements about it are also Internally inconsistent. - The 1952 lift-off and ten or more craft: Never properly tested (one undated second-hand account; not tested and not dismissed after a test; never examined by an independent party that I can find).

Claim 5: Seike, Heim, Pages, DePalma, Carstoiu have gravity-control theories or devices; orthodox science suppressed or ignored them

Agreement. All three: Seike is the only one with primary documents; the 1982 abstract has the Frenkel-Kramers equations and no gravity term; the book's NMR/ESR, Larmor and ferromagnetic slips are in the paraphrase; 3x10^12 W has no derivation; the 1984 coil abstract gives five data points with no balance, uncertainty, current-reversal or dummy-coil controls and no replication found; Heim, Pages, DePalma, Carstoiu are theory-level in the book with no data; the von Braun-Seike meeting has no independent record in a small (including Japanese-language) search; Seike was on the Physical Society of Japan programme for over 30 years (1965-1997, 54 CiNii records), so his work was not excluded from meetings, only not taken up.

Disagreements. - Seike equations: resolved in item 5 (mathematician right on the equations as written; convention ambiguity; no gravity term either way). - Seike coil: item 6. The pattern is not proportional to I or I^2 (exponent about 1.4), the intercept is -0.05 g, and 0 A is not zero. A single abstract cannot separate magnetic force, buoyancy from heating, lead forces and a real effect. Contrarian's d (a current-carrying coil losing weight would be conspicuous in weighed superconducting magnets [memory, medium]) is a fair expectation but not verified here. - "Suppression": the contrarian rates the historical existence of documents as "Established"; I split that: the documents exist (Seike's abstracts, Brown's and Hooper's patents) but a patent is not an examination of the physics. Suppression itself rests on four items in the book (superseded: the full list of nine incidents, with counter-evidence, is in the QE revision below): Mitchell's foreword; the "Nutty!" remark; Brown's report that the Navy declined on the ground that ion wind predicted no vacuum operation; the Searl raid. Counter-evidence: Saxl and Brown were published, and tested by others in print; Seike presented for decades; Project Outgrowth (USAF 1972) lists "antigravity propulsion" as a category while admitting the principles are obscure. Indifference to equation-free claims is not by itself suppression, and individual mistreatment is not ruled out. For Searl, the one item that can be checked in public records is the legal case, which now has a competing account (see below).

What would settle it. Seike: repeat the Mobius/Klein-bottle coil on a calibrated analytical balance with current reversed, a non-Mobius control winding of equal resistance, heating monitored, iron-free surroundings, and fit the current dependence; or obtain his 1985 follow-up abstract (31a-F1-1) and the book 『超相対性理論』 for the convention of J. Heim, DePalma, Pages: primary papers and apparatus, none yet obtained. Suppression: the Navy proposal record for Brown, the court/press record for Searl.

Final verdict (split). - Seike's equations as spin mathematics in E and H fields: Plausible, untested as a gravity effect (no gravitational term in the equations of motion; static-E behaviour depends on a convention; but see QE revision: the 1966 abstracts put Newton's constant in the spin-field energy tensor). - Seike NER "negative gravitational energy" and 3x10^9 kW: Not testable as stated (no derivation anywhere in the record). - Seike's 1984 weight loss: Never properly tested (self-reported, five points, no stated controls, no replication found; mundane artifacts not excluded). - Heim's contrabaric effect, DePalma's spin-inertia claim: Never properly tested. Pages, Carstoiu: Not testable as stated. - Suppression of these researchers: Not testable as stated in physics terms; historically open, with the Searl strand carrying a conflicting account.

Absence-of-evidence analysis (the record goes dark)

A. Searl's 1982-83 raid and prosecution, and the Searl device itself

What the record shows: the book (p.108) carries a hedged second-hand letter from Searl's associate (11 Dec 1984) saying a raid, a seizure of a "domestic type free-energy generator", a prosecution by the Southern Electricity Board for "stealing electricity", about a year's detention, arson and an assumed name. The Investigator could not search the British Newspaper Archive (blocked) and found no court or press record. My web search turns up a conflicting outline: a search summary of a sceptical wiki page says that in January 1983 a man who attacked electricity pylons (about 7,000 pounds of damage) was jailed for 15 months at Reading Crown Court, reported in the Evening Post on 5 January 1983, and ties this to Searl [web, low reliability: https://hatch.kookscience.com/wiki/John_Searl, page not opened]. The page cites its own source; I did not see the newspaper report.

Competing explanations: 1. Book's account is substantially right (an electricity-theft prosecution and detention). For: the date and place match (Reading Crown Court, early 1983, about a year or more of detention); the associate was close to events. Against: the charge differs from the one reported by the wiki summary; the letter is second-hand and hedged. 2. The conviction was for pylon damage, and the free-energy/theft story is the associate's or Searl's account of it. For: a published newspaper date and sentence length are specific; the 15-month term fits "about a year" of detention. Against: I have not seen the newspaper; the wiki is a sceptical interested summary; the two accounts could both be partial (separate charges are possible). 3. Suppression of an energy device by utility and state. For: the book's own narrative. Against: no document shows an examination of the seized device or any physics testimony; a theft or criminal-damage case is explained without inventing a device. Not excluded either: silence in a handful of online sources is not contradiction. 4. Mundane electricity-supply explanation (meter bypass, tampering, hidden supply; physicist's suggestion). For: the book's own charge. Against: no record; speculation.

The record that decides it: the Evening Post (Reading), 1982-83 (BNA, Reading Library); Reading Crown Court and Berkshire Record Office files; Southern Electricity Board archives; the original of the 11 Dec 1984 letter. The wiki's cited source. Also note the book itself (1977) predates the events; p.108 is a later insertion.

B. The Barret Report, Cain, Roos, the "Scientific Sub-Committee"

The Investigator found no trace of Arthur Cain's "published testimony", Jan P. Roos's Association for Pushing Gravity Research, P. L. Barret, or the sub-committee outside this book and works copying it (Davidson 1989; Stevens). This is documented in one published source, with no second found; silence in English and German web searches is not contradiction. Explanations: (i) very small private bodies with no archive; (ii) garbled or translated names (Barret/Barrett; Cain); (iii) press items in 1970s German or UK popular literature that are not online; (iv) lost records (the book mentions a fire); (v) suppression; (vi) the items are not what the book says. Evidence is thin for all; (i)-(iii) fit the book's own description of small circles, (v) rests on one letter, and (vi) must not be assumed without evidence. A generator reaching 1e9 V at "low speeds" would be easily metered and demonstrated; no such demonstration is on record, which is an anomaly in itself. Records to decide: Texas nonprofit registration (Roos), Schappeller's and Hilgenberg's texts, 1970s German popular-science press, the first-English-edition publisher's (Tamhelm Press, Lakemont GA) files, Searl's own book and early publicity (Life Magazine, Thames TV as cited in his own book).

C. Brown's lab notes and film

Brown says the Paris, Winston-Salem and GE vacuum lab notes "were never published and are not available to me now", and mentions movie film. A funded private programme (Bahnson Laboratories, GE) left no published data. Explanations: commercial or corporate retention; classification or Navy interest; loss; the results being weak. Evidence is thin on all; the Navy refusal is Brown's own account. Decisive records: Bahnson family papers, GE Space Center archive, Navy contract files.

D. Seike after 1985

Gravity Research Institute (1973 to his death in 2009), journal run to 1998, abstracts to 1997, no replication, no craft. Explanation set: the weight-loss claim did not reproduce; no mainstream group tried; fringe self-publication. The 1985 and 1982/83 abstracts were not reached, so the continuation of the 1984 record is unread.

E. Schaffranke's own career and the Bergier dating anomaly

Peenemunde/NASA/Boeing career rests on advocacy sources and on Bergier, who says "His identity is unknown to me"; no official record found. Bergier says the Rho Sigma report led to Electrodynamic Gravity Inc., but the company's patent was filed in April 1968 and Hooper died in February 1971, before the 1972 German edition. Explanations: Bergier's conflation, an earlier Rho Sigma text, continuation of the firm after Hooper. Decisive: Florida corporate records, Paperclip/NARA files, DNB/WorldCat for the 1972 edition. Nothing in the physics verdicts turns on this, but a reader should know the author's credentials are documented only by interested parties.

Summary of final verdicts

What would settle it (the shortest list)

1. Metre-scale rotor, electrometer: hub-to-rim voltage versus rpm (claim 3; prediction 6.5e-9 V at 1,000 rpm).
2. Hard-vacuum torsion-balance test of a Brown-type capacitor at 100-200 kV with spark and leakage controls (claim 1).
3. Seike coil: reversed current, non-Mobius control, balance calibration, temperature log (claim 5).
4. Evening Post (Reading) 1982-83, Reading Crown Court file, Southern Electricity Board records (claims 4 and 5, suppression strand).
5. Original Barret Report and Searl's own measurements, if any exist (claims 3 and 4).
6. Brown's lab notes and film (claim 1).

Open questions

• Is the static-E behaviour of Seike's equations growth or precession (the factor of i in J), and does his book supply a gravity link not in the abstract?
• Does the 1984 coil effect persist with current reversed and a dummy winding, and what does the 1985 follow-up show?
• Did Brown's vacuum thrust persist without any breakdown at 70-220 kV, and at what size relative to leakage-current thrust?
• Were Saxl's period shifts due to cage-to-fibre capacitance, as the 1992 and 1998 repeats suggest? (Full papers not read.)
• What was the exact nature of Searl's 1982-83 legal case: theft of electricity, pylon damage, or both, and was any device examined?
• Who were Cain, Roos and Barret, and where did the Barret Report appear first?
• Bergier's link between the Rho Sigma report and Electrodynamic Gravity Inc.: what does the Florida record say?
• Are Hilgenberg 1931 and Schappeller's texts any more quantitative than the book's account of them?
• Is there a charge-dependent gravitational coupling not excluded by equivalence-principle tests on neutral bodies? (The physicist flags the neutral-body gap; no test of it is on record in this project.)

Retention note

Every item the reviewers judged negatively is kept above: Brown's vacuum claim and Navy account, Saxl's measurement, Searl's account including the p.108 letter, Seike's 1984 numbers and equations, Heim/DePalma/Pages/Carstoiu, the Hooper patents (motional field E = v x B from rotating magnets, which both the physicist and mathematician identify as standard unipolar induction, not a measured gravity effect), the Bergier anomaly, Hilgenberg and Schappeller, and the ARL finding that ionic wind alone is three orders too small. Weighing them is left to the reader.

QE revision (Step 4b remediation)

Trigger: qe.md verdict MINOR. Inputs added: qe.md, and the four deep reads written for the remediation: deep/Ether-Technology-pp21-58.md, pp59-71.md, pp84-95.md and deep/Seike-1966-JPS-self-excited-NMR-negative-energy.md (page images of the two Seike 1966 abstracts). I relied on those deep reads' quotations, and re-ran two calculations myself ([calc], numpy, project venv). Web budget: none further used (7 of 8 spent above); every [memory] item below is tagged with a confidence and none carries a central verdict. No central verdict changes. Four verdicts are refined (listed at the end).

Q1. Seike 1966 abstracts: what they add, and what they change in my own item 5

What the abstracts are [read: deep/Seike-1966, from page images]: two primary, dated Physical Society of Japan abstracts, "Self-excited NMR of negative energy" I (5a-L-8, p.348, 21st annual meeting) and II (4a-B-1, pp.143-144, autumn meeting), plus a 1965 talk (11pK12) they cite. Theory only: no apparatus, number, sample, frequency or measurement. "NMR" here means resonant precession of a magnetisation vector I and an electric polarisation vector P in a rotating field on top of a static field H0, with resonance at alpha H0 + Omega = 0. Seike calls the medium an "energy-momentum ether" (paper II eq. 13), which matches the book's phrase on p.82.

Points that bear on my earlier arbitration:

1. A gravitational constant does appear. Paper I eqs. 4-6 write the energy tensor of the spin field with k, "Newton's gravitational constant", and eq. 3 (div of the transverse spin density = 4 pi times energy density) says an inward-pointing transverse spin is a "negative-energy field". My earlier text, and all three reviewers, said "there is no gravitational term in the equations". That remains true of the Frenkel-Kramers equations of motion (1966 eq. 12, 1982 and 1984 abstracts) but is not true of the 1966 paper I as a whole. Corrected. The step from this energy tensor to cancelling the Earth's gravity, to the 3x10^9 kW and to the three-condenser device is in no abstract I have; the deep read finds those book items "absent" from the 1966 text. They presumably come from his books (not obtained). Mapping of the book's paraphrase (pp.82-83) onto the abstracts: the ether, the Kramers equations, polar/axial spin, rotating AC field on a DC magnetic field, Larmor condition and "ferrite and titanate" (a garble of "magnetic body or dielectric", deep read's inference) all trace to the abstracts; "negative gravitational energies" is a join of two separate 1966 statements ("negative energy" and k in the tensor); "energy from the earth-gravitational field enters the system" and the power figure do not.
2. My item 5 (growth versus precession) is now better resolved. The deep read rewrites eq. 15 as dY/dtau = Y x (H + iE) with Y = I + iP (checked algebraically in the deep read), and the 1966 sign is +iota x H in d(iota)/dt (the 1982 reading had -iota x H; the conventions differ). I re-integrated eq. 15 undamped (RK4, alpha = 1, H0 = 1, H1 = 0.1, start I = z, P = 0, tau to 100) [calc]: at resonance, E1 = 0 gives max |I| = 1.00; E1 = 0.05 gives 1.15; E1 = H1 = 0.1 gives 10.05 (linear growth); E1 = 0.2 gives 1.9 x 10^7 (exponential); off resonance (Omega = -0.5, E1 = 0.2) gives 1.35. These reproduce the deep read's table. So the undamped equations as printed do give exponential growth at resonance once E1 exceeds H1, which is what the book says on p.83, and the mathematician was right and the physicist wrong on that point for real I and P. But Seike's own printed solution is the damped case (Gilbert-type damping [memory, medium]): a sech and tanh form that saturates, with omega squared = alpha^2 (H1^2 + E1^2) + (alpha H0 + Omega)^2 with a plus sign on E1^2; the deep read's rotating-frame derivation gets a minus sign, which would permit growth. The plus/minus difference may be a convention (iota real or imaginary, since the definition has i iota = m^4k) and I cannot settle it from one-page handwritten abstracts, as before. What can be said is that growth of I and P in this model is not extracted power, weight or a force.
3. An internal-consistency flag, not a verdict. Paper I eq. 6 gives T^00 proportional to -(iota^2 + kappa^2), never positive for real fields, while eq. 3 lets the energy sign follow the divergence of iota. The deep read marks these "not obviously consistent". Equation 6 has the negative-square form of Newtonian gravitational field energy [memory, high], but with k multiplying where Newtonian theory divides by it. An abstract is too short to call this a contradiction; it is an open question for the book 『超相対性理論』.

Verdict effect (claim 5). Seike's spin mathematics: still Plausible, untested as a gravity effect, now stated with the energy-tensor gravity link. "Negative gravitational energy" and NER as a power source: still Not testable as stated, with the added fact that the 3x10^9 kW, the device design and the Earth-field cancellation are traceable to no primary document in the project, and "NER" is a 1982 name for a 1966 construction. The 1966 abstracts show Seike's ideas were on the Physical Society of Japan programme 11 years before the book, which adds to the argument against "excluded from meetings".

Q2. Claim 1: Brown, Interavia 1956, Dudley, Saxl, Lippmann

New quantitative content from pp.21-58 [read: deep/pp21-58]:

• Interavia 1956 (vol. XI no. 12, p.992, p.38-39): 2 ft discs, 50 kV, 50 W total continuous input, 17 ft/s on a 20 ft circular course; later 3 ft discs, 50 ft course, 150 kV; "results so impressive as to be highly classified"; vacuum variants said to be "much more efficient". This is the book's only performance figure for the air-flying discs. 17 ft/s = 5.18 m/s [calc]. Thrust is at most P/v = 50/5.18 = 9.6 N if all the electrical power became useful work; that is a ceiling, not an estimate. An ion-wind estimate F = I d / mu = P d / (mu V) with ion mobility mu about 2e-4 m^2/(V s) [memory, medium] and an assumed gap d of 5-20 cm gives 0.25-1 N at 50 kV and 50 W [calc]. The book states no gap, mass, drag or current, so the figure is consistent in order of magnitude with an ion-wind explanation and cannot test one; it is not evidence of an anomaly either. The ARL result (ion wind alone three orders too small) concerns Bahder and Fazi's capacitor data, not these discs, and is not reconciled here. The Interavia article is a journalist's report of an unnamed party's claim; the original was not obtained.
• Dudley: US Patent 3,095,167; "rockets achieved heights up to six times the normal, utilizing the same propulsive charge" (p.33). No data. Never properly tested (nothing to test; the patent has not been read in this project). Kept in the record as a numbered claim.
• Rose 1952 report (p.25-29): five factors (separation, dielectric constant K, area, voltage, and "the greater the mass of the dielectric, the greater the effect", called inexplicable from the electromagnetic viewpoint). The first four are the standard factors of a capacitor's field and charge. The fifth is a qualitative claim without a number, and in the framing of this book is the nearest thing to a gravity-type signature in the air tests; it is untested in the record. Verdict unchanged.
• Brown's letters (pp.44-49) are as arbitrated above. Deep read confirms: "continued without sparks"; barium titanate "always exceeded air dielectric"; 4 ft rotor with four gravitors giving virtually the same torque in air and in transformer oil; oil to about 300 kV with thrust about linear in voltage; "the Navy rejected the research proposal" (Brown's account, an interested party). The oil-versus-air equality is an item the ion-wind picture would predict to differ (oil suppresses a free-ion wind) and I did not weigh it before. It is Brown's single-source statement of an experiment (4 gravitors, rotor, no numbers); documented in one source, no second found. It sits against the "largely ion momentum" admission in the same letter, and the two cannot both be general. It is a lead for the test already listed, not a verdict change: Brown's solar/sidereal/lunar variations remain Never properly tested; I add "air-versus-oil torque equality" to that bucket.
• Saxl: Nature 203, 11 Jul 1964, pp.136-138; 1 part in 10^7 timing; positive charge gives a longer swing; later periodicities over years; "post-doctoral student with Einstein" (p.50). Verdict unchanged (two repeats, mechanical explanation).
• Lippmann (1908) (p.23): "charged bodies offer greater resistance to acceleration; his experiments were quickly forgotten". The idea of electromagnetic mass is real: field energy carries inertia, delta m = U / c^2 [memory, high; I did not check the attribution to Lippmann or the book's description of his experiments, [memory, low] on that point]. For a 3 ft sphere (r = 0.4572 m) at 1e5 V, U = 0.25 J, so delta m = 2.8e-18 kg; at 1e13 V (U = 2.5e15 J), delta m = 0.028 kg [calc]. Verdict: the extra inertia of a charged body is Established in principle and negligible here; its sign is the opposite of Searl's claim. A charged body has slightly more inertia, not none, so the book's own "Lippmann" support works against its "inertia-free" claim. This is a retention item the contrarian flagged and both the arbiter and primer dropped.
• Speed-of-light "inventory" (pp.21-22): Roemer 1676 at 227,000 km/s (book's figure); Michelson 1926 at 182,284 mi/s; the Pasadena mile-long vacuum tube after Michelson's death, "variations of 12 miles per second and more" in seasonal and two-week cycles (Popular Science Monthly, March 1934), averaged to 186,271 mi/s; a re-measurement of the tube length found "no error". The book reads scatter as evidence that c varies. The mainstream reading is systematic error in a hard measurement (the later converging measurements, and the 1983 definition of c as exact) [memory, high on the definition; medium on the Pasadena detail, which I did not check]. Verdict: the scatter is a real historical record; "c varies" is Tested, not supported (later measurements by other methods agree to far finer precision). It does not support the ether or any Searl claim. It is instructive for a self-taught reader as a case of systematic error. Allen and Endean (28 Aug 1970; "particles at about twice the speed of light") and Sutton/Feinberg (tachyon talk): the project holds only the book's one-line description; I could not identify the Allen and Endean paper and will not guess. Not assessed (source not in the project); flagged as a lead. Harald Fischer, Karl Marx University Leipzig, 1968 dissertation on electrostatic fields and gravitational pendulum periods (library at Mainz): cited by the book to confirm Saxl, not obtained. The two later torsion-pendulum repeats (1992, 1998) were nulls; a Leipzig dissertation of the same kind has not been read. Never properly tested as a replication; unread.

Claim-1 final verdict list is otherwise unchanged. One wording change: the scale label for Dudley and Fischer is "Never properly tested" because they are unread and give no data in the book, not because I judge them testable and untested.

Q3. Claim 2: Lenard's double tube, Dirac and Einstein, Todeschini, eloptic energy

All [read: deep/pp59-71].

• Lenard's double tube (p.65), relayed by Seesemann (Locarno Congress of Radiesthesia report, 1956): two Plucker tubes joined by an aluminium window; "only the cathode rays entered the second tube", not the canal rays; Lenard concluded this "indirectly proves a transmitting ether". No date, pressure, voltage or data. The observation matches real physics: a thin metal foil (a "Lenard window") passes fast electrons (cathode rays) and stops slow, heavy positive ions (canal rays), because their ranges in matter differ enormously [memory, high]. No ether is needed to explain it, and the book's argument that "without ether both would behave identically" is wrong because the two beams differ in charge, mass and speed. Verdict: observation Established; ether inference Historically superseded but instructive. The experiment sits in the record next to the verdict; the book's single laboratory argument for the ether is not dropped.
• Dirac and Einstein (pp.62, 65): Einstein "revoked his stand in 1952 after Dirac proved the ether by mathematical means" (Seesemann, second hand). The book itself dates Dirac's statement 1954 on p.62 and 1952 on p.65. Dirac's Nature letter "Is there an aether?" (1951) is real [memory, high]. Einstein's own 1920 Leiden lecture "Ether and the Theory of Relativity" already said that general relativity's space is not "ether-free" in a limited sense, and carries no rest frame [memory, high]; this is the same source the book quotes via Lodge as "Sidelights on Relativity". So the 1952 reversal story does not hold up: the ether-like medium of general relativity and Dirac's vacuum are the field concepts the physicist described, with no preferred frame and no mechanical flow. Verdict: Historically superseded but instructive as a use of the word ether; no support for a mechanical ether or Searl.
• Todeschini (pp.66-68): "numerous tests" that "prove" light speed is relative to the chosen frame and that Lorentz contraction and time dilation "do not happen at all". No experiment is described: no apparatus, date or number. The dragged ether and the rotating layers (rotation speed falling with the square root of the radius) are as arbitrated in claim 2. Kraspedon's 400,822 km "etheric covering" with the Moon in its fringe is a Brazilian pseudonymous claim (English translation 1959); no source or measurement. All Never properly tested as experiments (named, not described) and Tested, not supported in the general dragged-ether form (stellar aberration, Fizeau), as before.
• Michelson 1923 quote (Reuterdahl, 14 Apr 1923; Brush 1976, via C. B. Wynniatt): that relativity need not make us reject the ether; the book gives a chain of citations to a Library of Congress box. This is a documented, specific, checkable item for the "Michelson-Morley did not disprove every ether" strand and agrees with the logic point already conceded. Retained.
• Eloptic energy, N-rays, Wuest, Hess (pp.69-70): Hieronymus's "eloptic energy" (refracted by a prism, conducted by copper wire, imprinted on film, "followed the astronauts"); Blondlot's N-rays (c.1900, Nancy), exposed by R. W. Wood in 1904 [memory, high]; the book mislabels Jean Becquerel as the discoverer of radioactivity (it was his father, Henri) [memory, high]; Dr Joseph Wuest (Munich, 1933-34) said to have been privately financed by Rudolf Hess, "mentioned to this writer by Dr. Wuest personally". The Hess claim is documented in one source, the author's personal communication with Wuest; no second source was sought in this project and none is on file. Verdicts: eloptic energy and the pseudo-physical list: Never properly tested (no data in the book); N-rays: Tested, not supported (historical, Wood 1904); Hess/Wuest: Not assessed, single-source, a lead for the Investigator. The efficiency "close to 100%" for Brown (p.69) has no measurement and no definition: Not testable as stated.
• Brown's vacuum thrust as eliminating "electric wind" (p.68) conflicts with Brown's own letter (pp.44-46, ion momentum "largely") and is therefore not an independent argument. Noted.

Claim-2 final verdicts unchanged.

Q4. Claims 3-5: pp.84-95 (sub-committee, Heim, DePalma, Pages, Carstoiu, French items)

All [read: deep/pp84-95]. The deep read confirms what I had from digests: no apparatus, equation or measurement is given for the sub-committee report (beyond the 1e9 and 1e10-1e14 V figures), Heim, DePalma, Pages or Carstoiu. The claims are verbal: DePalma "has discovered" spin changes inertia and "is able to prove it experimentally"; Pages describes electromagnetic propulsion by "Magnus effect" and an "Archimedean" density relation to a cosmic energy medium, with a design (electrons extracted and rotated around a central sphere, two inverted discs, ultra-high-frequency generator) and French patent FR 1,251,902 and a 1974 book; Carstoiu (SUNY Albany / University of Paris) states a "gravitational vortex" in an unpublished paper. Heim: lost eyes and hands in a laboratory explosion, degree 1954, institute 1958; his theory is said by an unnamed German physicist to give "the only consistent formula for the mass of elementary particles" (single anonymous source, no formula in the book). Verdicts unchanged: Heim, DePalma: Never properly tested; Pages, Carstoiu: Not testable as stated. The note is that the verdicts now rest on a full read, not on a digest.

New items for the record:

• The p.92 figure: full page, printed sideways, "German Research: Hypothetical configuration of a secondary gravitational field": streamlines around a closed vortex pair, belonging to the Heim section; no scale, no equation [read: page image p.92, per QE]. A picture, not evidence.
• De Fonvielle / Ducretet (pp.84-85): a 19th-century French writer describes a mica disc spun in front of a Wimshurst machine that "flies off", read as "gravity eliminated by centrifugal force". The claim is of rotation, not weight loss, and no data are given. A spinning insulating disc near an electrostatic machine acquires charge and is thrown off by ordinary electrical and centrifugal forces [memory, medium]. The book offers it as a precedent for Searl discs. Never properly tested; no data.
• Pages' device (pp.93-95) is a design description with a patent number and a book, not a build or a measurement. If the patent FR 1,251,902 is obtained it would be primary; it has not been.
• French official statements: Poher (CNES) analysed about 35,000 UFO reports by computer and "stated in public that UFOs exist"; Petit (CNRS plasma physicist) and a MHD engine model reported by the National Enquirer (2 Nov 1976); Minister of Defence Robert Galley, France-Inter, 1974, interview with J.-C. Bourret: the Ministry had "secretly studied the problem since 1954" (the book's paraphrase; not a quote of the broadcast). Galley's 1974 France-Inter interview is a documented event [memory, high], but the book's characterisation of its content is the author's. These are public official engagement with the subject, and so counter-evidence to the book's own suppression theme. They concern UFOs and plasma MHD, not Searl or Seike, and their relevance to gravity control rests on the book's reading. Retained, with that limit.
• Sub-committee report (pp.87-88): unnamed, undated; it adds "energy from no known source", a "non-oscillatory field which continually expands", an ionic discharge used to create a vacuum round the generator, and a speculation that "energy precipitation quietly reduces unstable elements". The editor's footnote calls the faster-than-light statement "probably somewhat erroneous". None changes claims 3-4.

Q5. Suppression: the full list with the counter-evidence

My claim-5 text said the book's suppression evidence "rests on four items". The deep reads show nine incidents [read: deep/pp21-58 and pp84-95; Mitchell's foreword and Nader 1974 are from the digest]:

1. Brown's 1% gravitor demonstration: "no scientist expressed the slightest interest" (p.34).
2. The faculty invited to the student gravitor demonstration: "Not a single member showed up" (p.35).
3. Pearl Harbor repeat before Admiral Radford (1950): "succeeded", but the lifting force was "still quite small" and the demonstrations were judged "of little commercial value"; Millikan reportedly said "Such a thing is impossible and out of the question" (p.36). The Millikan remark is reported, not sourced.
4. Brown sent to Europe; "over 75 patents in 12 major countries" initiated; no recognition from the scientific press (pp.36-37).
5. NICAP, September 1956: "The doors of America's scientific press clanged shut" (p.37).
6. The Navy rejected the research proposal because the ion-wind explanation predicted no operation in vacuum (p.46; Brown, an interested party).
7. Saxl: "Nutty!" from some officials (second-hand), colleagues who "look tactfully the other way" (p.53), privately financed (p.50-53).
8. Heim: ridiculed at the 1952 Innsbruck congress, "swore to remain silent"; Keyhoe (TRUE magazine, January 1965) says he was "put under official German security", which the book itself calls "somewhat hastily" (pp.89-90).
9. Searl: the 1982 raid and prosecution (p.108, second-hand, hedged), now with a conflicting outline in section A above.

Counter-evidence in the record: the six patents are confirmed by the Patent Office (the book's cross-check, pp.32-34); Brown was published in Science and Invention (1929) and Interavia (1956) and was tested by other parties (Talley 1988, Tajmar 2004); Saxl published in Nature and Physical Review D, and was repeated in print (1992, 1998); J. E. McDonald saw Saxl's apparatus and was "most encouraging" (p.52); Project Outgrowth (AFRPL-TR-72-31, June 1972, 28 members) lists antigravity propulsion as a field-propulsion category and admits the principles are obscure (p.54-55); Seike spoke at the Physical Society of Japan for over thirty years; Galley and Poher in France (Q4). Weighing: each incident is a single-source report by the party concerned (Brown, Heim's circle, Searl's associate) or by the book's narrator; none has an independent record in the project. Reception ranged from indifference (items 1, 2, 5, 7) to refusal for a stated physical reason (item 6) to claimed official interference (items 8, 9). Only items 8 and 9 allege active suppression, and neither is documented beyond one source. Indifference to qualitative claims without numbers is not by itself suppression. Verdict: unchanged, Not testable as stated in physics terms, historically open; the reader is given nine incidents to weigh, not four.

Q6. New absence-of-evidence analysis: the 1956 electrogravitics interest and its silence

What the record shows [read: deep/pp21-58, p.38-43]: in 1956 a journalist (Hoversten, Interavia) reported Brown-type discs with performance figures and that "results are highly classified"; Gerardin (Thomson-Houston, nuclear physics section, Le Raincy) proposed gravity as a residue of the electromagnetic interaction through multipole moments of nuclei; G. S. Trimble, Vice-President of the Glenn L. Martin Company, said development might take about as long as the atomic bomb; A. V. Cleaver of Rolls-Royce wrote in the Journal of the British Interplanetary Society (vol. 16, 1957, pp.84-94) that "a new principle" was needed, and reported that Arthur C. Clarke had been told it was "much ado about nothing started by a bunch of engineers who don't know enough physics". Velkoff (ASD-TR-61-642, February 1962) on electrofluidmechanics is cited in the addendum. After 1957 the book has nothing from industry on the subject except Brown's own 1973 letters and Project Outgrowth in 1972. The journalist reports "the most blank of stares" from government scientists.

A visible industry flurry followed by silence is an anomaly to explain, not a gap to wave away. Competing explanations:

1. Commercial and technical disappointment: a small effect traced to ion wind, which Brown himself says in 1973 was the main component in air, so the discs had no vacuum or space use; the Navy's stated reason (item 6 above) is exactly this. For: Brown's own letter; Talley and Tajmar found nothing without breakdown. Against: the Interavia piece says vacuum variants were "much more efficient"; no vacuum data were published.
2. Classification: the article says results were "highly classified". For: the claim is in print in 1956. Against: it is the article's statement, and classification would not usually explain no later patents or papers from non-defence parties (Rolls-Royce, Thomson-Houston). Not excluded.
3. Fashion and funding: the 1956 interest was part of a short-lived aerospace speculation; companies' internal "gravity research" programmes were discontinued or changed names. This is plausible but I have no source in the project [memory, medium that such programmes existed at Glenn L. Martin / RIAS; not checked].
4. Suppression: for: Brown's NICAP narrative. Against: no document; the pattern of interest then silence also fits explanations 1 and 3.

Records that would decide: the 1956 Aviation Studies "Electrogravitics Systems" report [memory, medium; exists; not checked] and the Glenn L. Martin / RIAS research files; Rolls-Royce and Thomson-Houston archives; Interavia vol. XI no. 12 itself; Velkoff's report; Navy contract and proposal records for Brown. These are already on the QE's Investigator list.

Q7. Retention and process notes added by this revision

• Restored to the record: Lippmann (and the charge-inertia result that argues against Searl's claim), Fischer and Oberth, Dudley, the Interavia numbers, the full suppression list, the French official statements, the p.92 figure, the Lenard and Todeschini items, the N-ray/Becquerel and Hess/Wuest items. None was dropped for being negative; the QE found them condensation losses.
• Not rechecked on the web: Dirac 1951, Einstein 1920 Leiden address, Wood 1904, Wuest, Galley 1974, the Aviation Studies 1956 report, the Lenard window range physics, the ion mobility figure and the Allen-Endean paper. All carry [memory] tags with stated confidence; none decides a central verdict. Web budget was spent in the main arbiter text (7 of 8).
• Items I still have not read myself: the book pages (I rely on the deep readers' quotations, as before); the Seike 1966 PDFs (the deep read worked from rendered images; I reran its numbers only).

Verdict changes (summary)

No central verdict moves: air thrust Established as an ionic effect, vacuum and Saxl gravity forms Tested, not supported, Searl voltages Refuted by calculation, over-unity Refuted by calculation, flight and weightlessness Never properly tested. The primer should take the corrections listed in qe.md section 7 together with the Q1-Q6 content above.
