Nikola Tesla revealed that an earthquake which drew police and ambulances to the region of his laboratory at 48 E. Houston St., New York, in 1898, was the result of a machine he was experimenting with at the time which.
"I was experimenting with vibrations. I had one of my machines going and I wanted to see if I could get it in tune with the vibration of the building. I put it up notch after notch. There was a peculiar cracking sound. I asked my assistants where did the sound come from. They did not know. I put the machine up a few more notches. There was a louder cracking sound. I knew I was approaching the vibration of the steel building. I pushed the machine a little higher."Suddenly all the heavy machinery in the place was flying around. I grabbed a hammer and broke the machine. The building would have been about our ears in another few minutes. Outside in the street there was pandemonium. The police and ambulances arrived. I told my assistants to say nothing. We told the police it must have been an earthquake. That’s all they ever knew about it."
Then some shrewd reporter asked Tesla at this point what he would need to destroy the Empire State Building and he replied:
“Vibration will do anything. It would only be necessary to step up the vibrations of the machine to fit the natural vibration of the building and the building would come crashing down. That’s why soldiers break step crossing a bridge."
Tesla is the only person which after his death got raided by the FBI, they seized all of his blueprints, they cleaned out his room, closet, and even took his slippers.
His inventions have since then been perfected over this time. They had all his blueprints and notes. It would be naive think they did nothing with that information.
Love and Light to all,
