Linerman-Peter (Peter A. Lindemann): central claims

Sources: two PDFs, both by Lindemann (D.Sc.), who has a commercial stake (Clear Tech, Inc.; he sells the book and runs free-energy.cc). No document in the folder is a test report. Patents are the inventors' own descriptions. The folder name "Linerman" is a spelling of "Lindemann".

Text note (not a source gap): both works have usable text. 81 of the 156 pages of free_energy_secrets.pdf were OCR; p.7 (the 1973 Tattler article) and the drawing sheets pp.85-91 are badly garbled. After the QE round every part of the book except the reference and back-cover pages (pp.153-156) has a deep read: the Tattler reprint, Chapter 1 and Gray biography (pp.7-21), the Vassilatos chapter (pp.22-38), Lindemann's Chapters 3-4 (pp.39-70), the Gray motor patent (pp.74-81), the Gray circuit patents (pp.110-125), the Tesla patents (pp.125-139) and the two Borderland articles (pp.141-152). Page numbers are PDF pages (printed page = PDF page minus 8). Page images were checked for the patent drawings, the Dollard photograph page, Fig. 34 and the Tesla patent p.136.

1. Lindemann's reading: Edwin Gray's "cold electricity" is Tesla's "radiant energy": a capacitor discharged across a spark gap in Gray's "conversion switching element tube" releases an Electro-Radiant Event that the output grids collect, and Gray's own explanation of the gain is wrong. The radiant-energy reading is Lindemann's alone; Gray's patents (US 4,595,975, 4,661,747) and his 1980 application describe higher efficiency from pulse timing and recovery of inductive-load (back e.m.f.) energy into a second battery, "on theory", with no figures and no radiant-energy or over-unity claim. Lindemann's four criticisms of Gray's FIG.1 (#42 drawn shorted, #28 grid unattached, #36 no coil symbol, #38 no return loop) were checked on the page image and hold, #38 only in part.
2. Radiant energy is a longitudinal, instantaneous, ether-borne effect that does not obey Ohm's law, thermodynamics or Maxwell's equations, so output can far exceed the energy lost in the primary discharge (Lindemann gives about 100:1 for Gray's circuit and about 1000:1 for the Methernitha Testatika; no input or output energy supports either figure). He cites Tesla's patent 787,412, which states a "mean velocity of about 471,240 km/s" (about 1.57 times the speed of light, close to pi/2 x 300,000 km/s) for a wave-train crossing the earth, but gives no derivation and does not say it exceeds c.
3. Seven families of "free energy" devices (radiant energy, permanent magnets such as Bearden's MEG at 6 W in, 96 W out, mechanical heaters, super-electrolysis, vortex/implosion engines, cold fusion, solar-assisted heat pumps) are "proven beyond all reasonable doubt", though no test report is given.
4. The First and Second Laws of Thermodynamics are not universal, so machines that draw heat or ether energy without a matching input are possible (Tesla's "self-acting" engine, Constable's etheric projectors, DePalma's rotating-magnet generator).
5. Gray's patents and press demonstrations (1973-76) are real but his venture was raided, prosecuted and ended (Lindemann's account: LA DA raid July 1974, a grand-theft charge that "couldn't stick and was finally dropped", a March 1976 plea to two minor SEC violations, death in April 1989 "under mysterious circumstances"). Beside it, a 1975 AP wire found by the Investigator reports 12 counts filed in May 1975 (1 conspiracy, 8 grand theft, 3 securities) with no outcome given; NewsReal 1977 (in the book) reports a plea to "a minor Securities and Exchange violation". Death year differs by source: 1989 (Lindemann), 20 April 1990 (VA-derived Find a Grave and FamilySearch records), 1993 (an anonymous KeelyNet informant). The biography's birth year is 1925, the contents page prints 1923. Lindemann's account is the only source in the folder for the raid, the dropped charge, the 32-day endurance test of a third EMA prototype, the Reagan certificate, the Inventor of the Year nomination and the SDI letters. The 1973 demonstrations (Tattler, Valentine; witnesses Hackenberger, Lens, C. V. Wood Jr., two unnamed physicists) report only a voltmeter reading and spoken efficiency figures.
6. Free energy is kept from the public by four forces (wealthy families and central banks, governments, charlatan inventors, and the public's own conduct), which Lindemann says are really one force of "unspiritually motivated" human behaviour, so the public must build devices itself. No evidence is offered for the murder, arson or patent-suppression claims.

Lindemann's statement about the motor (p.16): "if you try to build this motor according to the principles outlined in this patent, it doesn't perform anything like what was described". It implies first-hand experience but gives no build record, date, values or data; it is not a documented replication and is not discarded.

Narrower point the reviewers must keep straight: the text of Gray's motor patent US 3,890,548 claims only partial recovery of energy and requires a continuing battery supply; its geometry (13 1/3 degree steps, 27 firings per revolution) is internally consistent. The press and Lindemann go further than the patent.
