--- A perpetual motion machine is a hypothetical machine that could work infinitely without an external power source. Such a machine is impossible, as it would violate the first or second law of thermodynamics or both.
Energy can be neither created nor destroyed, only changed into other forms of energy. To work, a perpetual motion machine would have to produce more energy than it takes to operate, rendering the idea impossible. Still, it hasn't stopped engineers from attempting to circumvent or outright ignore the laws of physics.
Why a perpetual motion machine can never be built?
A perpetual motion machine is a hypothetical machine that can do work indefinitely without an external energy source. This kind of machine is impossible, since its existence would violate the first and/or second laws of thermodynamics. These laws of thermodynamics apply regardless of the size of the system.
What is the disadvantage of perpetual motion machine?
All break the laws of thermodynamics. In fact, we classify them based on WHICH law of thermodynamics they break. We have perpetual motion machines of the first kind - they violate energy conservation - they pump more energy out than they need to keep running. This includes most of the historical devices.
According to applicable laws of physics, a magnet motor can not run without external energy input. The same reason also makes it impossible for such a magnetic motor to generate energy autonomously.
The scientific objection to perpetual motion machines of this kind can be stated at the theoretical level in that they violate the second law of thermodynamics (that the entropy of a closed system tends to increase over time), or at the practical level in that they require the total elimination of friction and other ...
Why is perpetual motion considered impossible by scientists? Perpetual motion is considered impossible because it violates the first and second laws of thermodynamics. The first law, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transformed.
Has there ever been a successful perpetual motion machine?
For millennia, it was not clear whether perpetual motion devices were possible or not, but modern theories of thermodynamics have shown that they are impossible. Despite this, many attempts have been made to construct such machines, continuing into modern times.
People have suggested that placing the perpetual motion machine inside a vacuum would create a frictionless system. Unfortunately, even vacuums aren't ever 'perfect' vacuums and there is always some friction there that will stop the motion eventually.
Equivalently, "perpetual motion machine" (of the first kind) is a gadget that violates the conservation of energy. Planets don't - they move (almost) indefinitely but they don't do work and they're not being decelerated by any (significant) friction.
How close have we gotten to a perpetual motion machine?
Perpetual motion machines are fundamentally impossible. You can't get close to something that is impossible any more than you can get close to infinity. Note that the phrase ``perpetual motion machine'' is not used to describe an object that is in motion tending to stay in motion.
Perpetual Motion Machine (PMM) which can be applied to produce electricity, may be an alternative solution for the problem the world is facing today. The machine is designed to generate power from repulsive forces of permanent magnet without utilizing external sources.
1. Why is it impossible to create a perpetual motion machine? Perpetual motion machines violate the laws of thermodynamics, which state that energy cannot be created or destroyed, only transferred or converted. This means that a machine cannot continuously produce energy without an external source.
Despite this, because the mechanism continues to function, the Beverly clock is considered one of the world's longest running experiments, and is the closest anyone will ever see to a “perpetual motion machine.”
Although considered impossible by scientists, perpetual motion continues to capture the imagination of inventors. In 1900, Nikola Tesla claimed to have discovered an abstract method on which to base a perpetual motion machine, he wrote:
The closest machines we have to perpetual motion machines are various types of renewable energy technologies such as solar panels, wind turbines, and hydroelectric generators.
A magnet motor or magnetic motor is a type of perpetual motion machine, which is intended to generate a rotation by means of permanent magnets in stator and rotor without external energy supply. Such a motor is theoretically as well as practically not realizable.
What did Leonardo da Vinci say about perpetual motion?
"Oh, ye seekers after perpetual motion, how many vain chimeras have you pursued?" Leonardo da Vinci supposedly said of those attempting to make such devices. "Go and take your place with the alchemists".
The first law states that energy cannot be created or destroyed; it can only be transformed from one form to another. This principle implies that any energy generation process must adhere to conservation, making infinite energy seemingly impossible.
Perpetual motion machines can't exist because they would violate the first and second laws of thermodynamics. The first law states that energy cannot be created or destroyed, only transformed. Therefore, a machine that produces energy without any external input would violate this law.
