Leads for review

1. The inventor's own work

• Ten or more Handwerker documents existed on deltaavalon.com/immagini/ (2010-2013) that are not in the project folder, by file name: "Tesla and cold electricity" (English, Italian and German versions), "Tesla electricity English full version" and "... Verona Meeting" (Italian "Convegno Verona"), abstracts of the Verona meeting 15-04-2011 (Italian and English), "Tesla wireless" (English and Italian, "Tesla and the True Wireless"), "Tesla & l'auto elettrica wireless", "E-book L.M.D. waves and quaternions", "DELTA wireless power", "Water wireless power", "Wireless cold electricity" and "Wireless cold electricity - sailboat", "DELTA THOR earth pulse detector" and "DELTA THOR lightning detector", "Teslas prophecies" [web: Wayback CDX of http://www.deltaavalon.com/immagini/]. Bears on all claims; the E-book and the THOR detectors are new subjects. Only one was recoverable: research/files/2011-Handwerker-Tesla-and-cold-electricity-revised-English.pdf (2010 deck, 21 pp) [web: http://web.archive.org/web/20110813055236/http://www.deltaavalon.com:80/immagini/Tesla%20and%20cold%20electricity-revised%20English%20version.pdf].
• The 2010 "Tesla & cold electricity" deck (downloaded) adds experiments not in the folder: Tesla's "stout bars circuit" with lamps lit while short-circuited by a copper bar, and a 230 V/100 W halogen lamp lit under water; a flat-spiral coil whose lamp "repels the human hand, but attracts a suspended metal strip"; a vacuum-tube-driven Tesla coil; a receiving plate with a series neon lamp to earth; the claim that a Tesla coil's two main resonances obey f1 = (pi/2) f0 stated as a general rule (example f0 = 1 MHz, f1 = 1.57 MHz); and "MAGNETODIELECTRIC: is the dual of ELECTROMAGNETIC" [read: research/files/2011-...pdf p.11-22]. Bears on claims 1, 3 and on the paper's fo/f ratio.
• Two further Handwerker decks known only by their first pages: "Wireless electricity & longitudinal electric waves L.M.D., English full version, Verona meeting April 15, 2011" (41 pp) [web: https://www.scribd.com/doc/141881828/127929606-Tesla-Cold-Electricity] and "Wireless cold electricity: the electric sailboat setup" (2012), featuring the "G-03 Argon" generator prototype and a model sailboat with an aluminium-foil sail [web: https://www.scribd.com/document/118587128/Free-energy; https://studylib.net/doc/28693240/wireless-cold-electricity]. Bears on claim 5 (water antenna) and on the generator series (Xenon G-02 -> G-03 Argon).
• An earlier (2010) edition of the L.M.D. paper is listed on Scribd ("Tesla Coil", "2010 - DELTA Ingegneria") [web: Google snippet for https://www.scribd.com/document/... "Tesla-Coil"]. Comparing it with the 2011 revision would show what changed.
• His YouTube channel was "HorizonDelta" (joined 30 Aug 2010). In Feb 2012 it held 5 uploads, including "Tesla radiant electric energy receiver plate runs a motor (must see)" (2,496 views), "Wireless electricity by water 'antennae' - electric pendulum (must see)" (1,336 views) and "Tesla vs Einstein 1-0 Relativity ko - EU CERN experiment shows neutrinos faster than light speed" (1,671 views); the download page also names videos "Tesla & cold electricity", "Wireless power 1 & 2", "Wonderful lighting" [web: http://web.archive.org/web/20120201015033/http://www.youtube.com/user/HorizonDelta; Wayback of downloadsing.htm]. The channel is 404 by 2021. A 2016 re-upload survives: https://www.youtube.com/watch?v=qUvF-ZXejyI ("with his model boat electric sail, called G - 03 Argon"). Bears on claims 3, 5.
• He wrote articles on Tesla science and wireless in the Italian science magazine Heos, issues n.21, n.32, n.40 (2010) and n.1 (2011), and says DELTA articles appeared in Progettare, Rivista di Meccanica Oggi, Automazione Oggi, Watt, Il Giornale dell'Ingegnere [web: Wayback of homepageing.htm and downloadsing.htm]. Not yet found.
• Patent: ITVA20010043A1, "Device and method for fluid control", filed 29 Nov 2001, inventor Roberto Saverio Gab[riele?] Handwerker, applicant "Andromeda di Roberto Handwerker" [web: https://patents.google.com/patent/ITVA20010043A1/en; research/files/ITVA20010043A1.pdf]. An infrared fluid-state monitor; it shows a prior engineering-product career, not L.M.D. work. No patent on the L.M.D. claims was found.

2. Supporting information by others (witness accounts, demonstrations)

• Public demonstration, Verona, 15 April 2011, at the Confindustria hall, conference "Wireless electricity, auto elettriche, solar pond - Un nuovo mondo possibile", organised by Heos Editrice and Gruppo Giordano, moderated by Prof. Giovanni Bignami (named as president of COSPAR). Heos reports that Handwerker lit a "burnt-out" ("fulminata") halogen lamp in a basin of water and put his hand in the water "in the most absolute normality", and that "a small toy car without wires or batteries" was moved by wireless power transmission; the reporter adds "What practical developments these experiments may have, it is still too early to say" (translated). Handwerker is listed as "Delta Ingegneria - Busto Arsizio (Va)" [web: http://web.archive.org/web/20110830093118/http://www.heos.it:80/Cronaca_11/0100102_Casa-senza-fili-e-mobility-autonomia-energetica.htm]. A witness account by a publication that co-organised the event (an interested party); no measurements reported. Bears on claims 3 and 5 (wireless power, water) and on the "lamps lit in water" experiments.
• Marco Pizzuti, "Esperimenti scientifici non autorizzati" (2013), has a section on Handwerker (Verona demo "followed by local TV news" and attended by "several technical experts of the order of engineers"; the G-03 Argon sailboat "powered at a distance by a water antenna" through the insulating plastic of the tank; quotations from Handwerker) [web: https://www.nibiru2012.it/forum/idee-alternative/il-futuro-elettrico-di-nikola-tesla-15-135460.45.html, quoting the book; https://www.mangialibri.com snippet]. A popular book; it repeats the inventor's account, it is not a test.
• Tesla Society Switzerland hosted his "Tesla & cold electricity" deck under teslasociety.ch/info/handwerker/ (captured 28 Dec 2013) [web: http://web.archive.org/web/20131228084323/http://www.teslasociety.ch:80/info/handwerker/colde.pdf]. A form of endorsement by a Tesla society; no evaluation text found.
• No replication, test report or independent measurement of the L.M.D. or water-antenna claims was found in this run.

3. Closely related work

• Arbab I. Arbab and Zeinab A. Satti, "On the Generalized Maxwell Equations and Their Prediction of Electroscalar Wave", Progress in Physics vol.2, April 2009 (University of Khartoum; Omdurman Ahlia University) [web: research/files/Arbab-Satti-2009-Progress-in-Physics-electroscalar.pdf, from http://www.tuks.nl/pdf/Reference_Material/]. Their abstract: Maxwell's equations "are derivable from just one quaternion equation that only requires the Lorentz gauge"; new transformations produce a scalar wave; "This scalar wave exists with or without considering the Lorentz gauge"; the electroscalar wave "is found to be proportional to the electric field component along the charged particle motion"; "Maxwell equations are invariant under these transformations"; in the conclusion, "Maxwell equations are still exact and need no modifications". This is the source of Handwerker's equations (1)-(7) and of the Sigma field. Bears on claim 2. Arbab's later papers (arXiv:1003.0075, 2010; a 2014 arXiv paper; "The Analogy between Electromagnetism and Hydrodynamics", 2011) continue the line [web: Google results]. The 2011 hydrodynamics paper may relate to Handwerker's "hydrodynamics-electromagnetics analogy" (not read).
• Japanese blog "現代科学へのいちゃもん 239" summarises Handwerker's paper as an experimental detection of scalar waves with a Tesla coil and links it to Whittaker's work [web: https://aconkyou.web.fc2.com/nanamas/nana25a239.html]. A later account, sympathetic.

4. Historical record (incl. absence of evidence)

• The record goes dark in 2013. deltaavalon.com homepage captures are normal from Jan 2011 to 31 Mar 2013; on 29 May 2013 the homepage shows religious text ("God-believers and in particular Families are under heavy attack of dark evil forces", Psalm 7:6, 2 Chr. 20:15) and every PDF in /immagini/ returns 404; by 31 Dec 2013 the domain is a GoDaddy parking page; later a "Coming soon" page and parking [web: Wayback CDX timeline, research/pages/wayback-cdx-home-timeline.txt, home-20130529071515.html, home-20131231091640.html]. The YouTube channel HorizonDelta is 404 by Feb 2021. A Facebook commenter (2024-2025) says the channel and website "disappeared in 2013" [web: Google snippet]. Competing explanations to weigh: personal or family circumstances (the May 2013 homepage text suggests a personal crisis; that is a reading, not established); loss of interest or end of the hobby research; commercial reasons (product names Xenon G-02, G-03 Argon, DELTA Wireless Power suggest product intent); pressure or suppression (no evidence found for or against). Records that would decide: the Heos articles and any later Heos follow-up; Italian company register entries for DELTA Ingegneria and Andromeda di Roberto Handwerker (dates of cessation); the engineer's professional-register entry; the LinkedIn career record (an "Roberto S. Handwerker" worked as an engineer at PT S.p.A. 2016-2021, which, if the same person, means he returned to industry rather than disappearing).
• Google shows "removed in response to a legal request" notices on Handwerker queries; the Lumen notices (75850580, 95550170) could not be opened (403). These are commonly copyright (DMCA) removals of file-hosting copies; which results were removed, and who asked, is unknown.
• Professional standing: his own pages describe him as "Consulting Technical Professional of the Judge (C.T.U.)" for plants "from Lombardy to Sicily", fire-prevention certification (L.818/84), and "technical advisor to Italian Judges" [web: Wayback of consulenzeing.htm]; the site also lists a file "Dedica Gherardo Colombo.jpg" (a dedication from the Milan magistrate of that name, not opened). Location: Busto Arsizio (Varese) per Heos; "Milan" in his documents. The 2001 patent applicant "Andromeda di Roberto Handwerker" is in the Varese (VA) office series.

Corrections to earlier documents

1. deep/TESLA-THEORY-2-0d985e.md, section 1c ("Tension in the gauge step") and section 5 ("Gauge"): it says, from memory (medium confidence), that the Arbab-Satti novelty is that it does NOT impose the Lorenz gauge and that imposing it "removes the extra wave". Arbab and Satti's own abstract says the opposite on both points: Maxwell's equations follow from one quaternion equation "that only requires the Lorentz gauge", and "This scalar wave exists with or without considering the Lorentz gauge" [web: research/files/Arbab-Satti-2009-Progress-in-Physics-electroscalar.pdf, abstract]. So Handwerker's wording "by respect of the Lorenz gauge" follows his source; the deep read's recollection of the source was wrong. (Whether the scalar wave is physical, and whether the transformations really leave Maxwell's first-order equations unchanged, which the same deep read's SymPy check disputes, is for the Step 2 reviewers.)
2. deep/H2O-Wireless-electricity-2955b1.md and facts.json give reference [2] as "Arbab I.A. & Satti Z.A., ... Omdurman Univ., 2009". The paper was published in Progress in Physics, vol.2, April 2009, by Arbab (University of Khartoum) and Satti (Omdurman Ahlia University) [web: same PDF]. A citation detail, not a change of substance.
3. claims.md "Source gap" lists "his YouTube videos ('Tesla and cold electricity', 'Wireless by water antennae-electric pendulum')" as not found. The channel was "HorizonDelta" and is deleted; one Handwerker video survives as a re-upload (qUvF-ZXejyI); add this to the source gap.
