Can perpetual motion machines exist?

We all may understand that perpetual motion comes from a hypothetical machine that works from the concept of an indefinite and infinite energy source that powers this machine. If you have doubts as to whether these machines really exist or not, searching for the solution may be just as elusive. Science hasn’t given sufficient information about it. Though in a practical sense, these machines can’t be possible since they violate so many scientific laws. The main reason why perpetual motion can’t be built into actual machines is based on simple laws. These laws follow the conservation of energy, in which the first law of thermodynamics states that energy is always conserved. That means energy can be neither created nor destroyed, and instead it changes from one form to another. In order to make a machine move and to keep that motion continuous, that machine should acquire energy that has zero losses possible. Due to these conditions, it’s not possible to build perpetual motion machines.

In order to make these machine work, certain conditions must apply. First, the machine should not have friction since this will cause the loss of energy. Second, the machine should operate completely within a zero vacuum. Reasons for this are the air and friction that may cause the loss of energy also. Another consideration is sound which is also another form of energy that isn’t allowed in a perpetual motion machine. It is also noise that will cause further energy loss too. Machines additionally will not work in a vacuum without an energy source. Otherwise it can only be used as energy storage by itself. Since we’ll need energy to making the machine run without that energy created by other means, it must be brought from outside and into vacuum -if that is possible! There have been those who have claim to have built perpetual motion machines. Charles Redheffer from Philadelphia had built one such machine called a “Power Generator” in 1812, but later he was exposed with proof of another source that was used to generate the energy. Likewise -Sir William Congreve in 1827, is rumored to have built a capillary machine which disobey the law of the liquids. He too was also exposed that he used an inclined plane to create the infinite illusion. For all those who propose to build a machine of this kind, you would require enough energy to start the motion needed to power it continuously. And since that is the only energy you can produce (since as stated above), this is energy can’t easily be regenerated at the same rate which energy loss takes into account.
