2026-10-08 Tesla Society Switzerland (teslasociety.ch)

Found via Google "teslasociety.ch Handwerker": a Prezi page ("DonZ Device", 2019) cites http://www.teslasociety.ch/info/handwerker/colde.pdf. The live URL returns 404 (2026-10-08). The Wayback availability API gives a capture of 2013-12-28 (http://web.archive.org/web/20131228084323/http://www.teslasociety.ch:80/info/handwerker/colde.pdf); downloaded, it is byte-identical (MD5 06587505...) to the "Tesla and cold electricity - revised English version" deck from deltaavalon.com, so only one copy is kept in research/files/.

Bearing

The Swiss Tesla Society (founded in Zurich, 1956, per a Google snippet from thepeopleshub.org) kept a Handwerker folder (/info/handwerker/) on its site, at least until late 2013; the Japanese blog also notes "Teslasociety" in Handwerker's PowerPoint. A sign of recognition within the Tesla-society community (supporting information, priority 2); no evaluation or test by the Society was found. Next run: list /info/handwerker/ in the Wayback (the CDX server was rate-limited this run) and search the Society's site and press pages for Handwerker.
