Is there a perpetual motion machine in the world, and is there a perpetual motion machine in the wor

No. Historically, there have been many people who wanted to design a machine that would not consume any energy, but could do a steady stream of external work. Such a machine is known as a perpetual motion machine.

Historically, many types of perpetual motion machines have been proposed, as shown in the illustrations on this page. Although people have tried a variety of ways and made a variety of efforts, the perpetual motion machine has failed without exception. People call this kind of machine that does not consume energy a type of perpetual motion machine.

The discovery of the law of conservation of energy has made people further realize that any machine can only transform energy from one form to another, and cannot create energy out of nothing, so it is impossible to create the first type of perpetual motion machine. Is it possible to build a heat engine that completely converts different forms into each other without loss?

This heat engine has no condenser, only a single heat source, and the heat it absorbs from this single heat source can be used to do work without causing other changes. No! This imaginary heat engine is called a perpetual motion machine of the second type.

Although it does not violate the law of conservation of mass, it is also impossible to achieve because the conversion of mechanical energy Hanoi energy is directional. Therefore, a perpetual motion machine cannot exist.

To add up, the reason why the first type of perpetual motion machine is impossible is because it violates the first law of energy, and the second type of perpetual motion machine cannot be made, and while it does not violate the law of conservation of energy, it violates the directionality of energy transfer.

No, it exists only in the case of theory because the force is consumed during the motion.

No, because gravity is insurmountable, at least on Earth, and gravity is too small to ignore, not non-existent.

No, because energy loss is unavoidable.

There is no such thing as a perpetual motion machine in the world. A perpetual motion machine is a machine that does not require input energy from the outside world or only needs an initial energy to do work forever. It is impossible to manufacture such a machine because it violates the laws of conservation of energy and thermodynamics.

One of the ways in which the first law of thermodynamics is expressed is that the first type of perpetual motion machine is impossible. <

It can't exist.

Illusion 1, there is no equivalence between perpetual motion and long-term operation! We can't deny that someone has made a machine that can move for a long time, and it looks like a perpetual motion machine! But we have to distinguish between a "perpetual motion machine" and a machine that can run for a long time are completely different concepts.

"Perpetual motion machine" refers to a system that can last forever, and those so-called "perpetual motion machines" that can be made are only mechanized movements within a certain period of time, and with the loss of time and gravity, friction, etc., these so-called "perpetual motion machines" will eventually stop moving!

Illusion two, if you can't see the power source, you don't have the power source! Many people think that the earth is a huge perpetual motion machine, because the earth has been orbiting the sun for billions of years, and in the process of operation, the entire earth is still doing work, and the earth does not consume any energy, so the earth is a perpetual motion machine!

This statement is obviously unscientific, for example, we take a rope, one end of the rope is tied to a stone, if we want this stone to make a circular motion through the traction of this rope, we must give the stone a rock centripetal force, that is, to consume energy by hand and then transfer to the rope.

And the same is true for the movement of the earth, we know that the reason why the earth has been moving in a circle around the sun is because the sun provides it with a steady stream of centripetal force, and the ** of this energy is the gravitational force between the celestial bodies, that is, the earth has a steady stream of energy input, and the sun is this power source, so the earth cannot be a perpetual motion machine!

Illusion three, as long as the energy generated by its own movement can maintain its own motion, it is a perpetual motion machine! In itself, this statement is true, if the work done by a machine through motion can be converted into its own power, when this transformation reaches 100%, it can indeed be regarded as a perpetual motion machine. But this is not possible in real life!

In fact, there is a perpetual motion machine on the earth, but we can't see it with our right eye, and there are many mysterious things that are so big that science cannot study them

There is no such thing as a perpetual motion machine on Earth. A perpetual motion machine is a machine that can do work without consuming energy, which is unattainable on earth and violates the law of conservation of energy.

There is no real perpetual motion machine on Earth. It can be said that the perpetual motion machine does not exist, because it violates the law of conservation of energy, and the current science and technology have not yet developed a machine that can continue to do work without consuming energy.

Yes! Those who borrow real perpetual motion materials should respect the founder! The founders did not disclose the premise, and they could not make it public, but they also had to bear all the responsibilities!

There shouldn't be, because this is all nonsense, and no one has come at all, so without some evidence, I think it's impossible.

There is simply no perpetual motion machine on Earth, because the perpetual motion machine itself violates the conservation of energy.

Of course I don't know. Because this thing has not yet been discovered, and we can't deny the existence of something that is going to be discovered, so I don't know if there is one.

People are perpetual motion machines, and people who work at high intensity only eat more than one pound of food a day.

Perpetual motion machines are there, but we don't

Where there is a permanent magnet, there is a perpetual motion machine.
