Some of the most astonishing Tesla stories are dubious claims that have originated from the mythos surrounding Tesla and are either lies or unverified rumor. Amongst these colorful tales is that Tesla invented a steam-powered mechanical oscillator and while experimenting with it Tesla allegedly generated such a resonance that he was forced to use a sledge hammer to terminate the experiment, just as the police arrived. An article was published saying: "Tesla claims that in a few weeks he could set the earth's crust into such a state of vibration that it would rise and fall hundreds of feet and practically destroy civilization. A continuation of this process would, he says, eventually split the earth in two."
