A Perpetual Motion Machine by Another Name
The Keely Engine was a perpetual motion machine – a physics impossibility because it violates the first or second laws of thermodynamics. John Keely demonstrated a prototype to guests in his workshop. He poured water into its engine, then played a harmonica, violin, flute, or other musical instrument to activate the machine with sound vibrations. Soon, the device gurgled, rumbled, came alive, and provided pressures of up to 50,000 psi on display gauges. Harnessing that power, Keely arranged demonstrations in which thick ropes were ripped apart, iron bars were bent, twisted, and snapped in two, and bullets were driven through twelve inch wooden planks.
Keely made up science-y sounding terminology to describe the principles of his invention. Early on, he described his engine as a “vibratory generator”. Then he began to tell observers that they were seeing “quadruple negative harmonics”. At other times, he told gullible investors that he was going to make them filthy rich with his “hydro pneumatic pulsating vacu-engine”. If a listener sounded a note of skepticism, Keely drowned it with yet more science-y sounding phrases such as “vibratory negatives”, “atomic triplets”, “etheric disintegration”, and “atomic ether vibrations”.
