Posted by Bert Hickman 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
