What is Perpetual motion: Definition and 111 Discussions
Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate either the first or second law of thermodynamics or both.These laws of thermodynamics apply regardless of the size of the system. For example, the motions and rotations of celestial bodies such as planets may appear perpetual, but are actually subject to many processes that slowly dissipate their kinetic energy, such as solar wind, interstellar medium resistance, gravitational radiation and thermal radiation, so they will not keep moving forever.Thus, machines that extract energy from finite sources will not operate indefinitely, because they are driven by the energy stored in the source, which will eventually be exhausted. A common example is devices powered by ocean currents, whose energy is ultimately derived from the Sun, which itself will eventually burn out. Machines powered by more obscure sources have been proposed, but are subject to the same inescapable laws, and will eventually wind down.
In 2017, new states of matter, time crystals, were discovered in which on a microscopic scale the component atoms are in continual repetitive motion, thus satisfying the literal definition of "perpetual motion". However, these do not constitute perpetual motion machines in the traditional sense or violate thermodynamic laws because they are in their quantum ground state, so no energy can be extracted from them; they exhibit motion without energy.
HI Guys,
I have nothing to do ( home with the flue ) so I thought I'd post this and discuss the principles of PPM devices.
From what I understand the only way to achieve PPM is to generate a continuously changing event horizon ( Action horison )
This can be shown by example using solar...
This thought was inspired by reading the other thread "perpetuum mobile" where ZapperZ posted an interesting (but of course flawed) perpetual motion device. It was fun to analyze and to figure out why it didn't work and I was wondering if anybody else had neat ideas that seem to very...
its odd how many years have passed, but no one has accomplished it truly.
a perpetual motion machine is suppose to run forever.(Untill the Galaxy Collapses.)
i mean even if it wouldent be perpetual, it would last a good while like 7 to 10 decades of you family's tree like 300-500 years...
Perpetual Motion...
i have been tru some website regarding perpetual motion and all most 80% are out to motivate people into attemping to make perpetual motion, but ofcourse some are very non motivating,like this site. :(

i mean if such a device...
I guess this wouldn't be perpetual motion. But if you could lasso a photon wouldn't it keep pulling the object? Purly hypothetical of course. Maybe make a chamber that keeps the photons directed going one way, constantly pushing. That could turn a trubine in a genorator constantly creating a...
If conservation of energy can be violated classically, a la perpetual motion machines, what is that basic process or law which supercedes it? I often hear of complex physical systems supposedly creating more energy than input, but never have seen a fundamental principle characteristic to them...
I recently looked into a general theory of Perpetual Motion by using the gravity of some nearby large celestial object like the sun or perhaps for it being so close the moon. I attempted to solve that puzzeling mystey myself but got myself confused with equations and thoughts about Force...
I'm not sure if I got the name right, but anyways...
Suppose we have a nanoscopically small, but very clever device. (and with modern technology, this sort of thing is becoming almost practical...) It is basically just two compartments, with a hole in between. Contained in the compartments...
