Hi Pete, Thanks for the kind words! The machine you're describing is the Tesla Reciprocating Mechanical Oscillator (sometimes called his "Earthquake Machine") patent number 514,169 (Feb. 6, 1894, "Reciprocating Engine"). There's also a related patent, 511,916 (Jan. 2, 1894, "Electric Generator"). The device created low frequency vibrations which, if tuned to a structure's natural resonant frequency, could cause increasingly larger oscillations within the structure until (in theory at least) it shook itself apart. There is an in-print book available that decribes the device in great detail: "Nikola Tesla's Earthquake Machine: With Tesla's Original Patents Plus New Blueprints to Build Your Own Working Model" A web site that you may also find useful is at: Hope this helped, and best regards, -- Bert --
: Dear Sir,
: This is a fantastic web-site.As I perused the varoius pages, it came to
: me that you would be a person who might point me in the right direction
: concerning a subject that intrigues me.
: Do you have any information about the oscillator that tesla invented,
: whose resonant frequencies caused small, localized earth tremors? I've
: come across spotty reports of foundations of buildings being badly
: shaken.I've used ultra-sonic cleaners in my prior line of work, and have
: speculated that Tesla's phenomenon may be something akin to these
: commercially available instruments.
: Thank you in advance for any answer you may bring , and for the
: wonderful site.
: Sincerely, Pete Schade
