It can't. That's the simplest way to explain why no successful perpetual motion machine
has ever been built.

What law of thermodynamics allows perpetual energy machines?
The first law might allow a perpetual energy machine where energy is extracted from the surroundings to power the machine, but the second law explains why such a perpetual motion machine won't actually be able to work.
What is the need of the second law of thermodynamics?
Second law of thermodynamics used for prove of process reversibility, it provide the concept of system loss capability to perform work. Second law of thermodynamics is an effective tools to debunked pseudo-science in the field of perpetual energy (perpetual magnetic generator) and hoax energy saving scam.
Could you review the laws of thermodynamics?
Zeroth law of thermodynamics: If two systems are in thermal equilibrium with a third system, they must be in thermal equilibrium with each other. This law helps define the notion of temperature.First law of thermodynamics: Heat is a form of energy.Because energy is conserved, the internal energy of a system changes as heat flows in or out of it. Equivalently, perpetual motion machines of the first kind are impossible.Second law of thermodynamics: The entropy of any closed system not in thermal equilibrium almost always increases.Closed systems spontaneously evolve towards thermal equilibrium -- the state of maximum entropy of the system -- in a process known as "thermalization". Equivalently, perpetual motion machines of the second kind are impossible.Third law of thermodynamics: The entropy of a system approaches a constant value as the temperature approaches zero.The entropy of a system at absolute zero is typically zero, and in all cases is determined only by the number of different ground states it has
What law of thermodynamics is unavailable for doing work?
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
What is another name for the Law of Disorder?
Second Law of Thermodynamics
Why can't electric suppliers use electric motors to spin the generators?
If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.
What is the difference between perpetual motion machines of first kind and perpetual motion machines of the second kind?
Neither first or second kind of perpetual motion machines can be constructed, beacuse their existence violates the first law of Thermodynamics
What law of thermodynamics allows perpetual energy machines?
The first law might allow a perpetual energy machine where energy is extracted from the surroundings to power the machine, but the second law explains why such a perpetual motion machine won't actually be able to work.
Do you still use perpetual motion machines today?
We have never invented a perpetual motion machine and never will. A perpetual motion machine relies on the fact that we can get as much or more energy out of a machine than we put into it. However, this is in contradiction to the Second and First Law of Thermodynamics, respectively. The First Law of Thermodynamics states that you can't get more out of a system than you can get in. This is along the lines of 'energy cannot be made, only transformed'. The Second Law of Thermodynamics states that you can't be 100% efficient; some energy will always be lost to heat. An example uses Carnot (heat) engines; it would only be 100% efficient if we could reach absolute zero, which is impossible.
Why is imposible to create perpetual motion machine?
From the second law of thermodynamics, "It is impossible to convert heat completely into work in a cyclic process." Thus, energy in a system is gradually lost. Because of this, the energy will eventually run out (though it may take a very long time), and perpetual motion is impossible.
What is the need of the second law of thermodynamics?
Second law of thermodynamics used for prove of process reversibility, it provide the concept of system loss capability to perform work. Second law of thermodynamics is an effective tools to debunked pseudo-science in the field of perpetual energy (perpetual magnetic generator) and hoax energy saving scam.
Why is a perpetual motion machine not possible?
It's not possible because it would violate one or both of the laws of thermodynamics. The first law of thermodynamics says that you can't create energy from nothing, or to out it another way, you can't get more energy out of a machine than you put into it. The second law says that no machine is 100% efficient. You must actually get less energy out of a machine than you put into it. The laws of thermodynamics apply to the entire universe and all bodies within it, including alleged perpetual motion machines.
The fact that usable energy is always lost in an energy transfer is due to what 1 Newton's first law of motion 2 the second law of thermodynamics 3 Newton's second law of motion 4 the first l?
The second law of thermodynamics.
What is perpatual motion?
It is the idea of a machine continuously producing energy, without energy input - or producing more energy than what is put into the machine. This would violate the First Law of Thermodynamics (conservation of energy), and in general, it is not believed to be possible. No process is known which violates the conservation of energy. (A "perpetual motion machine of the second kind" would violate the Second Law of Thermodynamics; this is generally believed to be impossible, too.)
Which thermodynamic law has to do with entropy?
The second law of thermodynamics, generally stated, is that the entropy of an isolated system always increases in any natural process where change occurs. In a system at equilibrium, of course, the entropy remains constant.
Acoording to second law thermodyamic there is no machine which doenot work on extenal agenice but how Cosmic Polymath prepared a Perpetual motion machine?
A "perpetual motion" machine basically is one that violates either the First or the Second Law of Thermodynamics. This really isn't possible, according to our current knowledge of physics. Nobody - I repeat, NOBODY - has ever created such a machine. Sure, there have been lots of claims about creating such machines, but no such claim has stood up to a close scrutiny.
Who was the first person to try to make a perpetual motion machine?
the second person who wanted electricity.
