There is probably no true Nikola Tesla fan who hasn’t crossed this taught. This genius drew up plans for a death ray and an earthquake machine, the ideas that put him into conflict with big businesses and the authorities. He was also paranoid that his technology might end up in the wrong hands, so he buried 80 trunks of his findings in secret locations worldwide. These both bold and dangerous ideas led the FBI to search his laboratory to find the documents. After that, 60 years have passed, and the items remained classified, and a few years ago, the FBI released some of the files. The files offered some clues about the whereabouts of his research into weapons.
