Great, if frustrating reading there. I love the linked news article interviews with Lieutenant E.L. Zalinski.[1][2]
> Lieut, Zalenski's mirth interrupted him at this point. "Now," he resumed," when I started for Philadelphia I was careful to take with me a 10,000-pound gauge. That was my little equipment. This, as I suppose you know, or if you don't must take my word for it, is a standard instrument. Well, as soon as the Keely people saw this gauge they said to me, 'You had better not show it to Keely. It would only anger him!' Much I cared about angering him! I wanted justice. One of his partisans, however, informed Mr. Keely that I had brought this gauge with me, and the great man replied that he would not use it. In the course of his experiments he said he had got 50,000 pounds pressure. But—observe the but—he then remarked that he had broken all the pressure gauges he had. I then quietly rejoined that I had a pressure gauge which was only capable of registering 10,000 pounds. Said I, 'I would like to have you put it on, and break it for me.' Mr. Keely made no immediate reply to this. Shortly afterward, however, he remarked, with an air of feeble assertion, 'I do not believe in pressure gauges, anyhow.'"
