"Did that. It says he caused a building to vibrate enough to be noticed elsewhere. Nothing about a great quake."

BOB: Well there are numerous books on Teslas EQ machine, but I had the impression after a few years of reading up on it, that Tesla decided the machine would only be used for the wrong purpose... However, most articles tell that the device attached to a beam in the building, was felt for a few city block and the police were called along with other authorities...and that shortly before they discovered the source, Tesla took a heavy tool and removed the device...As far as I know, it was never mentioned again. Many believe that the US government felt some of Teslas devices and notions could possibly be used by foreign governments...or some such tale...and most of his writings were magically taken after his death living in poverty...It certainly makes for interesting reading....but I have not the math credentials to know what the heck it is all about...I wish I could understand...I am just the kind of guy who would try and replicate...
