Arbiter: Linerman-Peter (Peter A. Lindemann, with Edwin V. Gray's patents)

Role: Step 3. I read facts.json, claims.md, physicist.md, mathematician.md, contrarian.md, sites.md and the research notes, recomputed every number on which the reviewers differ, and made 8 web calls. Tags: [read] project document, [web] with URL, [memory] with confidence, [calc] my own arithmetic.

Stakes. Lindemann (honorary D.Sc. in complementary medicine; ex-Vice President of Borderland Sciences; co-founder of Clear Tech, Inc.; sells the book and runs free-energy.cc) is an interested party. Gray's patents are the inventor's own description. The National Tattler and Rex Research are advocates (Rex Research also points to Lindemann's products). Pan World Enterprises (Japan) was an investor in Gray. The Los Angeles District Attorney was the prosecutor. Each is reported as that party's account.

Source gap note

Not a source gap: both works have usable text. Limits that later steps must repeat: - Neither document is a test report. Every device figure in the book is Lindemann's assertion. - (Updated by the QE revision) Every part of the book except the reference and back-cover pages (pp.153-156) now has a deep read: pp.7-21, 22-38, 39-70, 74-81, 110-125, 125-139, 141-152. Page numbers in this file's first pass are mixed printed and PDF pages; the QE revision uses PDF pages (printed = PDF minus 8). - The only quantitative test claim (Crosby/Maize, 1973) and the only witnessed failure (Cronin, 1975) are known only from reprints on rexresearch.com [web: https://www.rexresearch.com/evgray/1gray.htm]. No Crosby document, no court file and no death certificate has been obtained. - Several verdict inputs on cold fusion, Meyer, and the Bearden MEG rest on [web] secondary summaries. The MEG replication (Naudin) primary page could not be opened (connection refused), so what Naudin actually measured is unknown to this review.

Recomputed numbers (where reviewers differed or only one checked)

Web checks done (8 calls)

1. Tesla US 685,957 "Apparatus for the Utilization of Radiant Energy" and US 685,958 "Method of utilizing radiant energy", both filed 21 March 1901 [web: https://patents.google.com/patent/US685957A/en ; https://patents.google.com/patent/US685958A/en]. This settles the physicist's medium-confidence memory. It also matters for the substance (see claim 1): the fetched summaries describe radiation (sunlight, X-rays, ultraviolet) falling on an insulated plate and charging a capacitor, which is not the spark-gap "Electro-Radiant Event" Lindemann describes.
2. Spark-gap arc drop "tens to hundreds of volts": retagged [web] above.
3. Naudin MEG primary page (http://jnaudin.free.fr/meg/megv1.htm): check failed (connection refused). A search returned only pointers, including a 2010 MEG paper by Jelinek and Pekarek [web: https://www.sisyfos.cz/old/files/meg/2010_Jelinek_Pekarek_MEG.pdf] that I did not read, and a note that Naudin reports "MEG does work". I cannot confirm any COP above 1 or equal to 1. The mathematician's "output equals input" and the contrarian's "COP not above 1" both rest on unread secondary text.
4. Testatika independent testing: a search returned rimstar.org pages stating that no one has been allowed to see the machines for years and that the only pictures come from a 1999 film of a 90-minute demonstration to about thirty engineers [web: https://rimstar.org/sdenergy/testa/report99.htm ; https://www.rimstar.org/sdenergy/testa/overview.htm]. Those pages are Testatika enthusiast sites, so this is their characterization. The Wikipedia Methernitha page has no testing information [web: https://en.wikipedia.org/wiki/Methernitha]. Result: no independent measurement found; access restricted.
5. Not re-checked because reviewers already cited Wikipedia/DOE/AP and no verdict turns on a changed fact: Meyer 1996 court finding [web: https://en.wikipedia.org/wiki/Stanley_Allen_Meyer], cold fusion 2004 DOE panel and 2019 Google/Nature result [web: https://en.wikipedia.org/wiki/Cold_fusion], Gray death record [web: https://www.findagrave.com/memorial/3813396/edwin-vincent-gray]. Remaining [memory], unchecked: Wimshurst current (low-medium), nerve strength-duration behaviour (medium), battery voltage recovery (medium), 35 U.S.C. 181 secrecy orders (high). No final verdict depends on any of them.

Corrected claim list (changes to claims.md)

Items 1-7 are from the first arbiter pass. Items 8-16 were added by the QE revision (below); claims.md already carries most of them.

1. Gray's tube circuit as "Tesla's radiant energy": this is Lindemann's reading. Gray's patents and endorsers describe partial recovery of back e.m.f.; Gray's 1980 application abstract says the same [web: rexresearch]. Tesla's two 1901 radiant-energy patents describe radiation charging a capacitor plate [web: Google Patents above], so even Tesla's patented "radiant energy" is not the spark-gap event.
2. Gray's death year: claims.md says 1989 (Lindemann). Three sources, three years: 1989 (Lindemann), 1993 (anonymous KeelyNet informant, 2000), 20 April 1990 (VA-created Find a Grave and FamilySearch tree) [web]. The 1990 date is the only one with a government-derived source, and the '975 patent lapse on 17 June 1990 is consistent with it. Birth year is also split: 1923 in the contents page, 1925 on the biography page [read] versus 8 Jan 1925 [web].
3. Charges: claims.md says "grand-theft charge dropped". The AP wire of 7 July 1975 reports 12 counts filed May 1975: 1 conspiracy, 8 grand theft, 3 securities (1+8+3 = 12) [web: rexresearch]. Outcome (dismissal or plea) is in no source found. Lindemann's version of the outcome is documented in one published source (his book), no second source found yet.
4. Claim 3's "proven beyond all reasonable doubt" is Lindemann's phrase; his own framing on p.1 is "a small amount of one form of energy to control or release a large amount of a different kind", which is an ordinary category (amplifier, heat pump) and weaker than energy from nothing. Several of his numbers go beyond that framing.
5. Dollard "400,000 V, 4 A, under 2,000 W": the 400,000 V is the caption author's guess ("anyone's guess") and the 4 A is an RF ammeter reading into ground; it is not a measured power gain.
6. Tesla patent number: 685,957 (apparatus) and 685,958 (method) are both correct.
7. The "134 degrees" is an OCR artifact for 13 1/3 degrees; the patent geometry is consistent (27 x 13 1/3 = 360).
8. (QE) "Lindemann built a copy of Gray's motor and it failed" is an overstatement. p.16 says "if you try to build this motor according to the principles outlined in this patent, it doesn't perform anything like what was described". No build, date or data is given. Recorded as his statement, not as a replication. [read: deep/ pp.7-21]
9. (QE) US 4,661,747 claims foreign priority: the book prints "[30] Dec. 16, 1983 [GR] Greece 24388" [read: p.117]. Google Patents shows the same priority date but lists the Greek documents as GR73274A / GR72864B [web: https://patents.google.com/patent/US4661747A/en]; the number printed in the book (24388) differs from that header and the difference is unexplained.
10. (QE) "203 hours" is a projection. The AP/Tattler-type text says the system "will operate continuously for 203 hours"; the text apparently from EvGray says "operated", yet also gives the only run length, "a 21-minute run" with "9.75 watts" consumed (a unit slip: it must be watt-hours) [read: saved rexresearch file]. [calc] 9.75 Wh in 21 min is 27.9 W average, not the 26.8 W quoted; 5,454 / 27.9 = 196 h, 5,454 / 26.8 = 203.5 h.
11. (QE) Tesla's 787,412 gives a "mean velocity of about 471,240 km/s" for the wave-train's surface passage and, in its first condition, defines the quarter wave with "the velocity of light" [read: p.136; web: https://patents.google.com/patent/US787412A/en]. It does not call this instantaneous. 471,240 / 299,792 = 1.572, about pi/2 (the half circumference divided by the diameter's light time) [calc]. A reading, not established.
12. (QE) Gray's patents and 1980 application contain no number of volts, amperes, watts, rpm or efficiency (only "about 2000 volts" and a "24 V" battery in the 1980 application's example). "Better efficiency", "a significant portion" recovered, all "on theory". The 3,000 V spark-gap figure is Lindemann's, from newspaper quotes. [read: deep/ pp.110-125; saved 1980 application]
13. (QE) Lindemann's nine "Electro-Radiant Event" items cite no source; item 9 (100 nanoseconds) is absent from the Vassilatos chapter he relies on, which gives only 0.1 ms, 100 microseconds and 1 microsecond. Tesla's "thousands of times greater" in 787,412 is "electrical movement" in a resonant circuit (Q = omega L / R); "a gain in power" is Lindemann's reading. [read: deep/ pp.22-38, 39-70, 125-139]
14. (QE) The 1973 demonstrations: only a voltmeter (about 3,000 V) is mentioned; efficiencies are spoken claims; the EMA test table in the second Tattler article lists "100 horsepower and 66 pounds of constant torque" with "brake horsepower ... 32.06". [calc] 32.06 hp at 2,500 rpm is 67 lb-ft, matching the 66 lb figure; 100 hp would need 210 lb-ft.
15. (QE) Tesla's 685,958 explains the charging by "minute particles of matter" thrown off by the sun, not by ether; the 1901 patents are not an aether claim. [read: p.131]
16. (QE) Dollard caption: the text on p.50 reads "the discharge from Eric Dollard's Magnifying Transmitter", so the physicist's correction 4 (caption does not say it was Dollard's coil) is wrong; facts.json is right.

Final verdicts per claim

Claim 1. Gray's "cold electricity" is Tesla's radiant energy; the tube releases an Electro-Radiant Event; Gray's own explanation is wrong

Agreement: all three agree the patents claim only partial recovery with continuing battery input; that no controlled neutral test exists; that Lindemann is right that Gray's "peak apparent power" explanation is not a gain (the mathematician's 15.3 J, 55 A, 190 kW illustration shows why); that the "Electro-Radiant Event" has no measurable definition; and that Lindemann reports, without build details, that a motor made to the patent's principles did not behave as the 1973 articles described (an advocate's statement against the claim, p.16; no build record, date or data; not a documented replication. Corrected in the QE revision).

Disagreement: - Verdict on the patent-level claim: physicist "Established"; mathematician and contrarian "Plausible, untested". Stronger argument: the mathematician and contrarian. Back-e.m.f. recovery into a battery is established circuit physics, but the patent claims a motor of unstated efficiency with no capacitance, inductance or power data, and no measurement exists. So the mechanism is established; the motor's usefulness is untested. - Whether "refuted by calculation" applies to the gain: physicist and mathematician yes (conditionally), contrarian no ("not earned"). Stronger argument: the conditional reading. Energy conservation rules out net gain only if every input is metered; no test meters it. So as a statement that a closed circuit yields more energy than the batteries supply, the calculation refutes it; as a report on this particular device, the gain is untested. - The mathematician's "99% lost in the voltage drop" error is confirmed (2 Va / V0). - The contrarian's point that the strongest case is "gain never measured with calibrated instruments" is fair, and so is the physicist's point that the one witnessed test (Cronin) failed and the only favourable test comes from an interested party.

Final verdict (split): - Partial back-e.m.f. recovery as the patents state it: Established (mechanism); the motor as an efficient, useful machine: Plausible, untested. - Net energy gain from the motor or tube: Never properly tested (not dismissed without testing: Crosby, the Japanese team and Cronin all report private tests; none was published or instrumented neutrally). As a closed-ledger net gain: Refuted by calculation. - Identification with Tesla's radiant energy, and ether source: Not testable as stated.

What would settle it: a metered build of the tube circuit: battery voltage and current integrated over a full discharge-recharge cycle (including the charging vibrator), calorimetry on the spark gap, energy delivered to a resistive load, energy returned to the second battery, with a dummy battery as control. Net battery energy rising across a cycle is the only result that would matter. A second, cheaper settle: obtain the Crosby/Maize report and the 1980 regenerative application.

Claim 2. Radiant energy is longitudinal, instantaneous, ether-borne, outside Ohm, thermodynamics and Maxwell; 100:1 (Gray), 1000:1 (Testatika)

Agreement: no equations are offered; longitudinal waves do not exist in vacuum in Maxwell's theory (div E = 0 forces transverse plane waves) though they exist in plasmas and near fields; the 1000:1 figure rests on a photograph caption; no gain has a measured numerator and denominator.

Disagreement: physicist "Tested, not supported" for the physics versus mathematician and contrarian "Not testable as stated" / "Never properly tested". Stronger argument: split. The instantaneity sub-claim is testable (delay should be L/c, 3.3 microseconds per km) and is contradicted wherever signal timing has been measured, which is all of radio, radar and GPS engineering [memory, high]; the vocabulary ("Light Ether", "incompressible gas") is untestable. The contrarian's observation that the Methernitha machines have not been opened to inspection is supported by [web] enthusiast sources; it explains the lack of a test and is not evidence of falsity. The physicist's resonance point also holds: a high-Q resonant circuit gives large voltage and current with no power gain, so the Dollard-style figure (apparent power V x I of about 1.6 MW against 2 kW from the wall, if the 400 kV guess were right) is not a power measurement.

Final verdict (split): - Instantaneous, non-Maxwellian propagation: Tested, not supported. "Light Ether" vocabulary: Not testable as stated. - 100:1 and 1000:1: Never properly tested (no protocol; no independent measurement of Testatika found). As net energy gain: Refuted by calculation. - Resonant voltage magnification (what the coil photo can show): Established; as power gain: Refuted by calculation.

What would settle it: a timing measurement of an impulse over a long baseline (distinguish c from instantaneous); an independent input-and-output power measurement on a Testatika unit with the drive input metered.

Claim 3. Seven families "proven beyond all reasonable doubt"

All three agree that no test report is given for any family and the umbrella phrase is unsupported. The families, with the arbiter's choice where reviewers differed:

Umbrella "proven beyond all reasonable doubt": not supported by anything in the folder.

What would settle it: for each family a metered input-versus-output test with the baseline written down. For the MEG, read Naudin's primary data and the Jelinek-Pekarek paper and rerun with true-RMS power meters (mean of V x I, not RMS V x RMS I).

Claim 4. First and Second Laws are not universal; self-acting engines, Constable, DePalma

Agreement: no test report for the named machines is in the folder; the laws are extensively tested; Lindemann's argument is historical, not a derivation.

Disagreement: physicist "Tested, not supported"; mathematician "Internally inconsistent" for the strong form; contrarian "Tested, not supported / Not testable". Stronger argument: all three are partly right and they are not in conflict. The mathematician shows that Lindemann's text calls the logic of the laws "flawless" and says Constable's projectors involve "nothing over-unity" (energy comes from the atmosphere) while also asserting local non-conservation; that is an internal inconsistency in the text. The physicist and contrarian show the physical claim is contradicted by every measured engine. The mathematician's Poynting-theorem point (local non-conservation would mean Maxwell's equations fail) and the unipolar-generator point (back-torque times angular speed equals power plus losses, so it is the conservation rule) are correct. The rain example [calc]: 1 million gallons falling 100 m releases about 1.03 MWh; condensing that much water releases about 2.4 GWh of latent heat, so a 100,000:1 ratio compares output to a trigger, not to the energy source.

Final verdict (split): - Laws not universal (strong form): Tested, not supported; Lindemann's text on it: Internally inconsistent. - Tesla's "self-acting engine" (continuous work from ambient heat alone): Refuted by calculation (Kelvin-Planck) unless a second reservoir exists. It was a reasonable idea in Tesla's era but is presented by Lindemann as current, so I do not use "Historically superseded". - Constable's projectors as a trigger-and-reservoir effect (cloud seeding type): Plausible, untested; as an over-unity machine: Never properly tested. - DePalma / Doczekal / Schaeffer / Wiseman: Never properly tested (named as working models in one source; no data in the folder).

What would settle it: a calorimetric cycle measurement on any one named machine; for DePalma, a torque-and-speed measurement with a rotating and a non-rotating magnet.

Claim 5. Gray's patents and demonstrations are real; the venture was raided, prosecuted, ended; death "under mysterious circumstances"

Agreement: patents real (US 3,890,548 issued 17 June 1975; 4,595,975; 4,661,747); raid and charges independently confirmed by the AP wire (DA's account); outcome unknown; death year conflicts.

Disagreement is only in labelling (the scale has no "historical fact" row): contrarian uses Established; physicist and mathematician use outside-the-scale or Never properly tested. I use Established for what a mainstream wire confirms and say plainly that this is a record claim.

Final verdict: - Patents granted, raid in July 1974, seizure of the prototype, plans and books, charges filed May 1975 (12 counts): Established (AP 1975, the prosecutor's side, plus the patent records). - Outcome (dismissal, plea, "two minor SEC violations" in March 1976): unknown; documented in one published source (Lindemann's book), no second source found yet. - Death: 20 April 1990, Sparks NV per VA-derived records; Lindemann and KeelyNet give other years; "mysterious circumstances" is documented in two advocate accounts that disagree with each other (one anonymous, with three police stories); no autopsy or death certificate found. Never properly tested (open). - Suppression as the reason the venture ended: Never properly tested. The record fits a securities case against a promoter whether or not the machine worked; the DA's own story says investors were reluctant to press charges (this agrees with Lindemann). Patents were granted during and after the prosecution. - The motor as a 99%-efficient or over-unity machine: see claim 1.

What would settle it: LA Superior Court file for the 1975 case; SEC News Digest 1975-76; USPTO assignment records for the three patents; Washoe County death certificate and an April 1990 obituary.

Claim 6. Four forces keep free energy from the public

Agreement: no evidence is offered for murder, arson, phone taps or patent denials (no names, dates, documents); the framework denies a "conspiracy" and then lists coordinated violence; and because "all four are aspects of one force" any outcome fits it. Its weight depends on devices that work (claims 1-4), and none was shown to. Contrarian rigor retained: the same lack of evidence applies to critics: "suppression" explains a lack of evidence and also fits a lack of effect, and records that could test it (secrecy-order lists, FOIA releases, the LA DA file) have not been obtained.

Final verdict: framework in its unified form: Not testable as stated. Specific allegations (murder, arson, patent denials): Never properly tested (no evidence offered; none found by the Investigator). Safety note: the "build it yourself" call involves charged capacitor banks (3,500 V in the patent); Lindemann's own account says touching the discharge path would throw one "clear across the room".

Absence-of-evidence analysis: where the record goes dark

The record goes dark at several places where it would be expected to continue.

A. Gray's venture after 1976. Gray had a funded company (about 800 shareholders from 1971 per AP), a Japanese backer, press and Caltech names attached, and three patents. After the 1975-76 prosecution, the press record stops, no instrumented test is published, and the next documents are patents of 1986-87 and a lapse in 1990.

Deciding records: USPTO assignment records (Zetech, Western States); LA Superior Court file; SEC digests 1975-76; Washoe County death certificate; Zetech and Western States corporate records; Internet Archive copies of KeelyNet 1990-91 files; California newspaper archives. None was reached (Investigator time limit).

B. The Crosby/Maize 1973 test. A named institute and engineer, a 203-hour claim, and no report ever seen. Explanations: the report exists but was private (investor property, Pan World); the Tattler garbled it; it was not a controlled measurement. Evidence: the units are mixed ("watts per hour"), the figures close with each other only under the W/Wh reading, and then give 278:1, which conflicts with the same article's 99% efficiency. The deciding record is the Maize report itself.

C. Testatika. One 1999 film of a 90-minute demonstration and years of closed access [web, enthusiast sites]; the only caption number is 1,000 W. Explanations: religious-community privacy; nothing to show; trade secrecy. The deciding record would be an instrumented independent test, which does not exist.

D. Lindemann's statement about the motor (p.16, PDF). [Corrected by the QE revision: the text says "if you try to build this motor ... it doesn't perform anything like what was described"; it never says he built one.] It is a first-hand-sounding statement by the book's advocate, with no build record, date, values or data. It stays in the record as evidence against the motor, weighed as his characterization. A dated, measured account of any build would settle whether it says anything about Gray's hardware.

E. Replications of the 1980s tube circuit. A present-day forum community exists (groups.io EVGRAY; Reddit r/plasma_pi), said to work on a simplified Lindemann circuit; it was not visited. No replication result is claimed or denied here.

What would settle it (summary)

1. Metered tube-circuit build with a cycle energy ledger and a dummy battery (claims 1-2, 5).
2. The Crosby/Maize report, or an equivalent instrumented dynamometer run with battery energy integrated (claims 1, 2).
3. Naudin's MEG primary data and an independent true-RMS repeat (claim 3).
4. Instrumented Testatika test; timing test for "instantaneous" propagation (claim 2).
5. Court, SEC, USPTO assignment and Nevada death records (claims 5, 6).
6. For a reader: the energy arithmetic above (Crosby 278:1, Adams 12.3:1, solar 28:1, arc-gap 2Va/V0, 15.3 J pulse) can be rerun by hand.

Open questions

• Is there a Crosby Research Institute report, and in what units were the figures?
• Did the 1980 "Regenerative Energy Recovery System" application or the Canadian and Japanese family members (CA 1030600, JP S50-74712) state measured results? They may differ from the US text; not read.
• What happened to the 1975 charges, and why does Lindemann's account (one charge, dropped; 1976 plea) differ from the AP count?
• What did Naudin actually measure on the MEG (COP above 1, about 1, or not stated)?
• What do present-day EVGRAY experimenters measure on the simplified circuit?
• How was 1989 cold-fusion replication handled (funding and publication barriers)? Not examined here.
• Whether DePalma's N-machine and the Dollard coil have any independent measurement (not searched).
• How the Tesla radiant-energy patents (radiation charging a plate) relate to Lindemann's spark-gap "radiant event": a reader question for the primer.

QE revision

Role: arbiter, after qe.md (verdict MINOR) and the QE deep reads (deep/free-energy-secrets-45a60f.md, sections for pp.7-21, 22-38, 39-70, 110-125, 125-139, 141-152). I re-read those deep reads, the saved rexresearch file (the 1980 application and the Crosby/Maize text) and made 2 web calls (Google Patents US 4,661,747 and US 787,412). Tags: [read] project document, [web] URL, [calc] my arithmetic. Page numbers are PDF pages. No central verdict changes; six sub-verdicts are sharpened or relabelled (see the table). The QE's remediation items (a) to (j) are answered in order.

(a) The "own build" statement corrected

p.16 reads: "But I discovered soon enough that if you try to build this motor according to the principles outlined in this patent, it doesn't perform anything like what was described in the Valentine articles ... If you happened to get into the discharge path of those capacitors, you'd be thrown clear across the room. What's more, the amount of energy that could be recycled from this arrangement is negligible" [read: p.16]. He received the patent in 1978. No build record, date, values, instruments or witness is given. It is documented in one source, his own book; he has a stake (he sells the later "cold electricity" explanation). Weight: it implies first-hand experience and is evidence against the motor as described in the press, but it is not a documented replication and not evidence about Gray's hardware. Silence on details is not evidence either way. I corrected the three places that used "own build" (claim 1 agreement list, the absence table row, section D). Related first-hand statements in pp.39-70: "I have tried dozens of methods to combine the voltage from one source with the current from another ... It doesn't work" (undated, no data, p.67), and Fig. 34 is "DRAWING BY: Peter Lindemann D.Sc., August, 2000" with no build [read: p.66]. The contrarian's and physicist's use of the motor statement as a build is withdrawn; their other points stand.

(b) The Greek priority

US 4,661,747 (Appl. No. 791,508, filed 25 Oct 1985; division of 662,339, filed 18 Oct 1984, which became US 4,595,975) prints "Dec. 16, 1983 [GR] Greece 24388" [read: p.117]. Google Patents confirms a Greek priority of 1983-12-16 but lists it as GR73274A / GR72864B [web: https://patents.google.com/patent/US4661747A/en]. The application number printed in the book therefore does not match the web header; one of them may be an OCR or database variant, which I cannot resolve. Why an Idaho inventor filed in Greece first, who the Greek applicant was, and what it described, are unknown. The filing is about 10 months before the US parent. Deciding record added: the Greek patent office (OBI) file for the 16 Dec 1983 application and its publication GR 72864, with the applicant's name and text. It could show whether a 1983 disclosure contained numbers that the US text lacks.

(c) What the 1980 application and the patents say about measured results

The saved text of Gray's 10 April 1980 application, "Regenerative Energy Recovery System, e.g., for Electromagnetic Propulsion" (an unidentified British application number), reads [web: saved copy of https://www.rexresearch.com/evgray/1gray.htm]: - Back emf "can result in energy loss ... A regenerative energy recovery system ... employs switching 6 to discharge a capacitor 3, through an inductive load 5, e.g., a motor. When capacitor 3 is discharged, a diode 4 creates an alternative circuit path through which inductively maintained current may then continue to flow, for example to charge a battery 7." - Phase A: battery No. 1, "shown as 24 V", raised by a DC-to-DC converter to charge a capacitor "to a high voltage of about 2000 volts". Phase B: the discharge "is rapidly passed through switch number 1 ..., through the inductive load (item 5) and through the now closed switch number 2 (item 6), and through the energy recovery battery number 2 (item 7)". Phase C: switch 1 disconnects the capacitor and the inductive current continues through items 5, 6, 7 in a closed loop. - The inventor "believes this to be a more efficient use of energy". It describes "a part of the EMF, that is normally lost" as recaptured. Result: the 1980 application is the plainest statement of the mechanism: the recovery battery sits in the discharge path itself (phase B) and then carries the freewheeling current (phase C). It contains two numbers, 24 V and about 2000 V, and no measurement, efficiency, run time or witness. The saved text ends there; whether the Canadian and Japanese family members differ is not read. The same holds for the circuit patents: no volts, amperes, farads, ohms, hertz, watts, rpm or efficiency percent appear in pp.110-123; every efficiency statement is hedged ("on theory", "anticipated", "the inventor's contention") and none claims output above input or a radiant effect [read: deep/ pp.110-125]. The radiant-energy reading is Lindemann's. These documents are the inventor's own description and are not test results.

Lindemann's four FIG.1 criticisms were checked on page images [read: page image p.115]: #42 drawn shorted between the high-voltage node and ground, with the load-line terminal open (confirmed); #28 a triode symbol with a floating grid and no heater (confirmed); #36 a plain box with two arrows and no coil symbol (confirmed; the patent text calls it the load inductance); #38 wired to the batteries through switch 48 but no return loop through the load is drawn (partly confirmed: right about the loop, wrong that no battery connection is shown). The drawing is a hybrid: the charging chain is conventional, the discharge, control and recovery parts are not closed, and the patent gives no component values. The patent calls FIG.1 "a schematic circuit diagram"; Lindemann calls it more a block diagram. Both are characterizations; the checks side with Lindemann on the drawing facts. This does not change claim 1: it supports the point that nobody can build a working copy from the drawing, which weakens any "failed replication" reading as much as any "worked" reading.

Fig. 34, Lindemann's own "probable schematic", is his conjecture, not Gray's. It has internal slips: the battery roles are swapped between p.55 (battery 18 runs, 40 is charged) and Fig. 34 and pp.64-67 (40 runs, 18 is charged); the timer box says "10 usec" while the text says 10 to 50; the text calls the front end "identical to Gray's" while Fig. 34 draws an electromechanical vibrator and two gaps for #42 [read: deep/ pp.39-70]. His energy ledger: no input or output figure for any Gray device. "100 times greater" has no number behind it and may be a restatement of Gray's 1%/99%. The 99% "lost in the voltage drop" is his statement. [calc] A 12 V battery fed from a 3,000 V capacitor gets 12/3,000 = 0.4% of the energy carried per coulomb, so "near zero" recovery through the spark-gap path is right and the gain must come from somewhere else if it exists; my first-pass 2 Va / V0 result for the arc loss still holds. Lindemann reads "2 micro-farads" and "4000 Volts DC" on a capacitor in a photograph he had scanned; the images in the PDF are too coarse to confirm. [calc] 0.5 x 2e-6 x 3000^2 = 9 J (16 J at 4,000 V).

(d) "203 hours" is a projection

The AP/Tattler-type text: "The system will operate continuously for 203 hours ... since the total battery power consumed is only 26.8 watts per hour" [web: saved copy of https://www.rexresearch.com/evgray/1gray.htm]. A text apparently from EvGray Enterprises ("Power Plant of the Future", an interested party; the author is unidentified in the file) reads "The total battery power consumed by the motor during a 21-minute run was only 9.75 watts; this equals 26.8 watts per hour. The system operated continuously for 203 hours (8-1/2 days)". So the only run length stated is 21 minutes. [calc] 9.75 Wh over 21 min is 27.9 W, not 26.8 W; 5,454 Wh / 26.8 W = 203.5 h; 5,454 / 27.9 = 196 h. The two texts disagree about tense and the second contradicts its own 21-minute run. The 203 hours is an extrapolation from a short run unless a long run is documented elsewhere, and no such document is known. The arithmetic of the ledger stands (278:1 if the units are W and Wh), as does the unit slip. The mathematician's and primer's "run time 203 hours" should read "projected 203 hours (from a 21-minute run)". The 1973 test table in the second Tattler article adds an internal tension: "100 horsepower and 66 pounds of constant torque" and "brake horsepower ... 32.06" at "better than 2,500 revolutions per minute for more than 30 minutes" [read: page image p.11]. [calc] 32.06 hp at 2,500 rpm corresponds to 67 lb-ft, matching the 66 lb figure; 100 hp would need 210 lb-ft. Both numbers are in one paragraph and no tester or dynamometer is named.

(e) Witnesses, history and statements restored to the record

Each is described with its source and stake; none is a measurement. - 1973 demonstrations (the Tattler, 1 and 8 July 1973; the reporter, Tom Valentine, is also the author of the 1977 NewsReal piece; both are advocate press) [read: pp.9-12 and page images pp.7, 10, 11]. Magnet toss in Gray's laboratory, Van Nuys: a 6 V car battery, capacitors, two 1.25 lb electromagnets; "a voltmeter gradually rose to 3,000 volts" (the digit is uncertain on the image); the top magnet "hurled into the air" more than two feet and "remained cold"; Richard Hackenberger (Gray's Vice President of Engineering; formerly Sony, Sylvania, US Navy per the Tattler) caught it and said "only 1% of the energy was used - 99% went back into the battery". Fritz Lens operated the battery. Two unnamed "knowledgeable physicists" are described as bewildered. Gray says the magnets have been popped "for the past 18 months with that same battery". Second demonstration: a 15-amp motorcycle battery, two capacitors, six 15 W bulbs, a 110 V television and two radios, "the small battery was not discharging"; C. V. Wood Jr., president of McCulloch Oil, "began looking around for hidden outlets"; a 40 W bulb dropped in water, hand and finger in the water, "no shock". Instruments mentioned: a voltmeter only. No ammeter, calorimeter, run time or meter on the battery is described. This is the most-cited evidence for Gray and it is a witnessed demonstration reported by a sympathetic journalist, with the load and the battery state not measured. It is not a controlled test, and it was not examined by any neutral party on record. Wood and Hackenberger are named people who could have been asked later; no later statement from them was found. - The EMA motor test in the second article: four 6 V batteries, "better than 2,500 revolutions per minute for more than 30 minutes", "found to be as fully charged as they were at the beginning" (the page image is partly small print) [read: page image p.11]. The 100 hp/32.06 bhp tension is in (d). - Gray biography [read: p.21; Lindemann's uncited narrative; each item documented in one source, his book, except as noted]: third EMA prototype "successfully tested for 32 days straight before it was torn down for analysis" (no load, instrument or witness); nominated "Inventor of the Year" by the "Los Angeles Patent Attorney's Association" by February 1976; a "Certificate of Merit" from Governor Reagan (no date or document); letters to "every member of Congress ... and the President, Vice President, and every member of the Cabinet" offering the technology for SDI with "not a single reply"; the car with Paul M. Lewis; the late-1970s statement that Zetech, Inc. acquired the technology. The NewsReal 1977 article independently (but also by Valentine) reports a guilty plea to "a minor Securities and Exchange violation". The Tattler (1973): "Gray ... one of 14 children"; NewsReal 1977: "one of six", "dropped out of school at 14" (a discrepancy in the sources, stated). Also in the Tattler: a Wall Street offer of 20 million shares at $25, "bankruptcy" proposal, Japanese interest. - Letter of 11 October 1973 signed "Renate Gray" for EVGray Enterprises to Lindemann: "due to our security we are unable to give out any information about the motor or the company" [read: page image p.13]. It shows the company withholding information three months after the press demonstrations. - KeelyNet informant (anonymous, 2000; research/ notes) [web: saved KeelyNet mirror]: a claimed "1,000 HP" at 10,000 rpm (with the page's own 1 hp = 760 W slip); "the FBI and others suppressed anything they could"; a promoter who "gathered lots of investor money for Gray, with as much as 60 million being placed offshore"; Gray "worked for NASA as a mechanic" with Dr. Alexei Popov. One anonymous source each. The $60 million statement bears both ways on claim 5: a promoter's fraud, or money that vanished. Brian Desborough's testimonial of "incoming spikes over 1000 amps" [read: p.156] is an interested-party endorsement with no instrument named. - Lindemann's own first-hand items: the 1986 bulb test with Tom Brown (a filament bulb lit with the two men about 6 and 8 ft from the transmitter, no sensation, no instruments, no bulb rating) [read: pp.50-51]. The mathematician's near-field reading (two bodies in the field of a large coil) is a physics explanation, not a refutation of the account. The photo of the discharge was taken by Alison Davidson in 1986 and supplied by Brown [read: p.50]; the caption's 400,000 V is "anyone's guess", 4 A RF ground current "measured on a radio frequency ammeter", under 2,000 W from the wall; no output power is given. - Lindemann's anti-fraud stance, for balance: he names a con man who raised "more than $100,000,000 ... barred from doing business in the State of Washington ... jailed in California" (unnamed in my notes; checkable in public records) and lists Keely, Hubbard, Coler and Hendershot as undecided [read: ebook p.5]; he writes "The patent office is crammed with hundreds of 'permanent magnet motors', none of which work, to my knowledge" [read: p.150]; and he calls Gray's "peak apparent power" explanation "clearly not true" [read: p.67].

(f) Deciding records added

Borderland Labs videos (1987-88) and "unpublished photographs and unreleased video footage of experiments (1986-1989)" [read: pp.153-154]; the Crosby Research Institute report (and who "Dr. Norm Chalfin" is); the Greek patent file (b); Tesla's 1892 "Dissipation of Electricity" lecture and the Scientific American 1872 account of Thomson, to check the Vassilatos statements; Dollard's own publications and measurements for the impulse-duration claims; Tewari's hydrogen report; Austrian patent AT 155744 (1939, Doczekal) and DE 42 44 016 A1; Constable/Atmos Engineering rainfall and gauge records. These join the earlier list (court, SEC, USPTO assignment, Nevada death records, Zetech and Western States records, KeelyNet 1990-91 files).

(g) Claim 2: Tesla's 471,240 km/s and the other Tesla patents

Tesla's 787,412 [read: p.136; web: https://patents.google.com/patent/US787412A/en, sentence confirmed]: the earth resonance needs, first, the earth's diameter to be "an odd multiple of the quarter wave length - that is, of the ratio between the velocity of light and four times the frequency"; second, low radiation, frequency below 20,000 per second, "the lowest frequency would appear to be six per second"; third, a wave-train lasting "not less than one-twelfth or probably 0.08484 of a second", "taken in passing to and returning from the region diametrically opposite the pole over the earth's surface with a mean velocity of about four hundred and seventy-one thousand two hundred and forty kilometers per second". There is no derivation. [calc] 471,240 / 299,792 = 1.572 (pi/2 = 1.5708); 0.08484 s x 471,240 km/s = 39,980 km, about the earth's circumference; at 6 Hz c/(4f) = 12,491 km against a diameter of about 12,742 km [memory, high]. The quarter-wave condition uses c, so the patent itself uses c for the wave and a larger "mean velocity" for the surface passage. The geometric reading (a path along the surface of half a circumference, pi R, divided by the straight-line light time across the diameter, 2R/c, gives pi/2 times c) fits the digits; it is a reading, not something the patent says. It would then be a bookkeeping figure for the surface path and not a signal faster than light. The patent states no experiment, site, date or witness. So the patent does not support "instantaneous" propagation: it gives a finite, specific time. The "instantaneous, incompressible" language comes from Vassilatos (p.36: "Should the path be 300,000 kilometers long, the impulse at the source end will reach that point as quickly as at all other points", "According to this view") and from Steiner via Lindemann. Tesla's 1897 patent 593,138 uses 185,000 miles per second (about 297,700 km/s, about c) as an illustrative speed [read: p.127]. "Thousands of times greater" in 787,412 describes an electrical movement in a resonant secondary, "directly proportionate to the inductance and frequency and inversely to the resistance", that is the quality factor Q = omega L / R [memory, high]; the "many tens of thousands of horse-power" is a rate of flow in the oscillating system, not power delivered from a source. Lindemann reads the quoted sentence as "a gain in power" [read: p.46]; the text does not say power. Tesla's 685,958 explains charging by "minute particles of matter" emitted by the sun, positively electrified, with the ground as "a vast reservoir of negative electricity"; "ether" is only the view he declines to adopt [read: p.131]. So Lindemann's ether and radiant energy are not in Tesla's own patents; they are his and Vassilatos's reading.

(h) Claim 2: the Vassilatos chapter, item by item

[read: deep/ pp.22-38] The chapter is Vassilatos's narrative (author-publisher of "Secrets of Cold War Technology: Project HAARP and Beyond", 1996, with a stake in the thesis); it has no footnotes or tables. It names one primary Tesla work, the lecture "Dissipation of Electricity" (about Christmas 1892), with two short quotations, and the year 1842 for Henry and 1872 plus Scientific American for Thomson; no patent number appears. The experiments, with what each offers: - Disruptive discharges, exploding wires, "gunshots", shockwaves felt through glass and copper at "nearly fifty feet": no instrument or data. - The 1892 oil-bath experiment ("a hole, some two inches in depth"), impulse-time dependence, magnetic arc quenching: attributed to Tesla's lecture; the two-inch figure is the only measure; I did not check it against the lecture, which is not in the folder. - Pulse thresholds (p.30): above 0.1 ms pain and mechanical force; 100 microseconds or less not felt; 1.0 microsecond a sense of heat; shorter pulses cool breezes and vacuum-globe light; credited to Tesla and "elucidated by Eric Dollard, who also successfully obtained the strange and distinct effects". No instrument is named; the 100 ns threshold in Lindemann's item 9 does not appear in this chapter. Dollard's reproduction is one sentence, with no date, apparatus or measurement; he is cited three times and never referenced. - "10,000 volts per inch" of coil (24 in to 240,000 V), "zero current" in long secondaries, "interception current" of hundreds or thousands of amperes (Dollard's statement): numbers quoted, no instrument or source. - The U-shaped copper bar with shorted lamps (p.33): documented in this chapter only; unnamed "witnesses"; no ratings or voltage. [memory, medium] Tesla's 1891-92 lectures show lamps lit across a heavy copper bar with high-frequency or impulsive current, where the bar's inductive impedance diverts the current; that is an ordinary-physics reading, not checked on the web here. - Superluminal "raylines" and "radiant matter" incompressible and massless: no cited measurement. Weighing: single-source or uncited does not mean false, and the Tesla lecture and the Thomson account are real documents that can be checked. As evidence the chapter gives claims, not data. It does not change a verdict: instantaneous propagation stays "Tested, not supported" for the physics (timing of radio, radar and GPS) and the vocabulary stays "Not testable as stated"; the pulse-duration effects (cool, painless, light-giving short impulses) are testable in principle with an oscilloscope and a calibrated source and "Never properly tested" as stated, since the only supporting statements are uncited. Safety note: the claim "impulses under 100 microseconds are completely safe" is not supported by any measurement in the folder; high-voltage capacitor discharges can injure whatever their duration. [memory, medium, not web-checked]

(i) Verdict changes after deep reads 1 and 3

Gray's FIG.1 is not a complete working schematic (checked on images); Lindemann's critique of the drawing holds. This does not overturn any final verdict; it sharpens them. The Borderland articles (pp.141-152) also change three sub-verdicts, below.

(j) Page numbers and process corrections

This revision uses PDF pages. The first pass mixed printed and PDF pages (the physicist's "p.59-60" for the 99%/100:1 passage is printed; PDF pp.67-68). Spot checks agree with the QE: the "99% lost in the voltage drop" and 1000:1 quotes are correct as quoted; the motor patent figure (12 V batteries, 18 capacitors at 3,500 V) is correct. Process notes: the Investigator's time on run 1 (472 s) is below 9.5 minutes, so the unreached sites are "not reached (stopped early)" (a sites.md fix for the next run, not mine). Web checks this revision: 2 of the 8 budgeted; the unchecked [memory] items are the ones listed in the first pass, plus the Tesla 1891-92 short-circuit lamp demonstrations (medium), and no verdict rests on them.

Open questions that remain

• The Greek file for the 1983 priority, and why the book prints 24388 while Google Patents lists GR73274A / GR72864B.
• Whether the Canadian and Japanese family members of the 1975 patent, or the full 1980 British application, contain any measured result.
• Whether a Crosby Research Institute report exists, and whether any run longer than 21 minutes was documented.
• Who Dr. Norm Chalfin is, and who took the 1973 EMA test measurements.
• Whether the Tattler's second-article engine figures (100 hp against 32.06 bhp) were corrected in the original print.
• The 1986-89 Borderland footage and photographs, and any instrument record of the Dollard coil measurement (the 4 A and under 2,000 W figures).
