Queries and what they returned

  1. "Rolf Schaffranke" "Rho Sigma" -> positive. It led to the Chappell Natural Philosophy Society wiki entry (see the naturalphilosophy-wiki note); a Reddit r/TownsendBrown post saying "Rho Sigma is the pseudonym for Rolf Schaffranke (1921-1994). He died in Hayesville, N.C., and was buried in Stone Mountain, Georgia" (snippet only, not opened); a Jeane Manning Substack saying Schaffranke used the pseudonym "for fear of being ostracized by his peers" (snippet only); and AbeBooks "Sigma, Rho [= Rolf Schaffranke]". [web: google results page]
  2. "Schaffranke" NASA Marshall Peenemünde obituary 1994 -> partial. The AFU (Archives for the Unexplained, Sweden) book list has "Bearden, T.E. & Schaffranke, Rolf: The new Tesla electromagnetics and the secrets of electrical free energy, 1982?" https://www.afu.se (2018 book-list PDF). No obituary found.
  3. Schaffranke "Post-Relativistic Concepts" OR "Space Energy" symposium pdf -> positive. It led to the New Energy News Nov 1993 article by Schaffranke (see the newenergytimes note) and to John Davidson's The Secret of the Creative Vacuum, which cites "letters to Rolf Schaffranke, 1973" (see the archive-org note). A particlephysicist.files.wordpress.com PDF cites "Schaffranke, 'The Development of Post-Relativistic Concepts in Physics and ...'" (snippet only).
  4. "Shinichi Seiki" anti-gravity Uwajima -> positive. The only English hits relay the book's own paragraph (zamandayolculuk.com, Scribd) plus the naturalphilosophy wiki. This led to the Japanese spelling 清家新一 (Seike Shin'ichi).
  5. 清家新一 反重力 宇和島 ("Seike Shinichi anti-gravity Uwajima") -> positive. It found ja.wikipedia (see that note); departure-ruins.com and Instagram posts saying the "Gravity Research Institute" (重力研究所) was founded in 1973, later renamed the Space Research Institute (宇宙研究所), and closed when Seike died in 2009; and a 1992 YouTube clip of Seike.
  6. "Searl" 1983 Mortimer electricity board court prison "abstracting electricity" -> negative (no results with quotes; without quotes, only unrelated legal pages).
  7. "John Searl" 1983 prison electricity board Mortimer Berkshire newspaper -> partial. Scribd has "Antigravity The Dream Made Reality" (Searl's own book, with a list of his publicity "until 1983": "1. Life Magazine, USA. 2. Thames TV Program ..."). A FlipHTML5 copy of The UFO Technology Hackers Manual has the line "If I went to Reading and went through the newspaper I might find that Searl was sentenced for something else than not paying his electricity bill" (snippet), which points to Reading local papers for the 1983 sentence. Not opened (time).
  8. "Jan P. Roos" OR "Jan Roos" "pushing gravity" Austin -> partial. The only hits relay this book: Davidson's Secret of the Creative Vacuum, Wendelle Stevens' UFO Contact from Reticulum ("Jan P. Roos of the Association For Pushing Gravity Research seems to have come the closest to understanding ..."), and copies of Ether-Technology. No independent record of Roos or of his association.
  9. Saxl 1964 Nature "electrified" torsion pendulum gravity -> positive, as a citation trail. Saxl, E.J., "An Electrically Charged Torque Pendulum", Nature, 11 July 1964, p.136; Saxl & Allen, "Observations with a Massive Electrified Torsion Pendulum: Gravity Measurements During Eclipse", IRI Report #702 (cited in T. Valone 2012, ScienceDirect, and in an AIAA paper). It also found Hathaway & Williams 2021 (see the arxiv note).
  10. "Arthur Cain" Searl "mill-wheel" OR "mill wheel" -> negative. The only hit is a copy of the book itself. Cain's "published testimony" has no other source online.
  11. Searl Cain Mühlrad Antrieb Flugscheibe (German: mill-wheel, propulsion, flying disc; tried because the Cain quote may be translated from a German source) -> negative.
  12. Hilgenberg 1931 "Über Gravitation, Tromben und Wellen in bewegten Medien" -> positive. The book Roos cites is real: Ott Christoph Hilgenberg, Über Gravitation, Tromben und Wellen in bewegten Medien (On gravitation, vortices and waves in moving media), Berlin 1931, self-published, 78 pp. Holdings: WorldCat; Met Office Library (https://library.metoffice.gov.uk); BSH digital library (Annalen der Hydrographie 1940 lists it). There is a history-of-geophysics paper, "Ott Christoph Hilgenberg in twentieth-century geophysics" (academia.edu). Hilgenberg is better known for his 1933 expanding-earth book Vom wachsenden Erdball [web: snippets]. The 1931 ether-sink gravity theory sits on the expanding-earth line of thought.
  13. Schaffranke "Raum & Zeit" OR "Raum und Zeit" Einstein Äther Danzig -> the page did not render (AI-mode loading screen), so it was re-run as 14.
  14. "Schaffranke" "Raum & Zeit" (verbatim mode) -> positive. It found raum&zeit articles by Schaffranke (see the raum-und-zeit note). Scribd "Gravity Field Energy Insights" says: "A German edition was titled 'Forschung in Fesseln' (Research in Chains)". Konstantin Meyl's Scalar Waves cites "Rho Sigma (Dr. Rolf Schaffranke): Forschung in Fesseln, das Rätsel der Elektro-Gravitation, Ventla-Verlag, Wiesbaden, 1972, Page 67". Hidden Energy (Manning) cites "Rolf Schaffranke's Ether-Technology, Young Harris, GA".
  15. "Forschung in Fesseln" "Rho Sigma" Elektro-Gravitation Verlag -> positive. Bibliographic record from AbeBooks, Amazon.de and Booklooker: Forschung in Fesseln: das Rätsel der Elektro-Gravitation, Ventla-Verlag, Wiesbaden-Schierstein, 1972, hardcover; reissued by VAP (Verlag für Außergewöhnliche Perspektiven) 1994 (ISBN 3922367909) and 1996 (ISBN 3922367917). A German original therefore predates the 1977 English book by five years. It also led to the Inexplicata/Bergier text (see that note).
  16. "Electrodynamic Gravity" Sarasota -> positive. Electrodynamic Gravity, Inc., P.O. Box 1976, Sarasota FL was William J. Hooper's company; it holds his patents (see the google-patents note). Scribd "Antigravity Burridge": Hooper "After retirement he became Research Director of Electrodynamic Gravity, Inc., Sarasota, Florida. Dr. Hooper passed away suddenly on February 14, 1971" (snippet).
  17. "Searl" 1983 "Mortimer" laboratory raid electricity prison Wormwood -> negative (only unrelated genealogy and catalogue pages).
  18. 清家新一 フォン・ブラウン (Seike + von Braun) -> negative. Nothing ties Seike to Wernher von Braun beyond the book. A Qiita article (2023) reads Seike's Ultra-Relativity (secondary; not opened). Lazydog.sakura.ne.jp reports a Seike lecture at a Kyoto University festival (snippet).
