Google Patents WO2013155644A1 - Perpetual motion machine Thanks to Suresh Vishwanathan from Bangalore, India, for this question.WO2013155644A1 - Perpetual motion machine Only by engineering a solution by which an object in motion can consume some store of energy or gather energy from an external source can we approximate perpetual motion.” “The laws of physics indicate that perpetual motion would occur if there were no external unbalanced forces,” he says. Is perpetual motion possible? According to Frey: No, but things can be engineered to approximate or mimic it. But inevitably, its spring needs to be rewound.” Carefully designed, a grandfather clock exhibits short-term perpetual motion. A mechanism called an escapement ensures the push is always in the right direction, counterbalancing the drag force on the pendulum. We use a weight to provide push and gears to modulate the force of the weight. “Grandfather clocks rely on a pendulum that appears perpetual, but in fact, it is only engineered to act that way. For objects like the moon, the unbalanced forces are small compared to what would be needed to slow down such a large object, so the changes are very slow.įrey swings back to pendulums. For objects here on earth, the forces are relatively large and tend to slow motions down after a short period of time. Why? Because even in space there are unbalanced external forces. Even so, with advanced instruments and careful measurements, we can determine that the moon’s motion is changing: it gets farther away from the earth on average by about two centimeters each year. It goes around the earth every month and has been doing so at almost constant speed for a very long time. Perpetual motion requires an initial force and a sustaining force.”Īs it turns out, the moon is very nearly a perpetual motion machine. If you could pump forever, you would swing forever but once you remove that energy, you soon stop. A playground swing is a different kind of pendulum,” he notes, “but you can keep it going by pumping your legs. This is because of friction with the air. As it turns out, “external unbalanced forces” - non-zero net forces outside applied to the object by another object - are everywhere in our universe.ĭan Frey, an associate professor of Mechanical Engineering and Engineering Systems, explains it this way: “If you take a metal washer and put it on the end of a string and start it swinging, it goes back and forth but eventually it stops. The second part of Newton’s first law of motion, however, throws a wrench in the process. In the late 1600s, Sir Isaac Newton penned a famous law: “Every body remains in a state of constant velocity unless acted upon by an external unbalanced force.” The first part of the sentence (up to “velocity”) suggests that perpetual motion is not only possible but inevitable for any object already in motion. For details, we must begin with Sir Isaac Newton… By Jason M. Is it possible to construct a perpetual motion machine?
