Abstract The Keely Motor has been the subject of endless discussion over the past 120 years. John Ernst Worrell Keely's original patent was filed with the US Patent Office in 1872 and to this day resides in the 'Reserve' section under 'Motors, Hydropneumatic' and not generally available to the public. During all these years no indication of any kind was ever given as to its mode of function, its energy source or any principle of operation. In fact this motor was on display in The Franklin Institute in Philadelphia for many years labeled a perpetual motion machine. How does it work? What principle of physics is used in its design? Can these concepts be used today? This paper reveals for the first time answers to most of these questions. The answers are found in principles of water hammer, (cavitation, implosion) and vibration physics. Click to view photo gallery of this motor. |
