The Physics of Perpetual Motion The first law of thermodynamics is the law of conservation of energy. It states that energy is always conserved. It means that energy can be neither created nor destroyed. Instead, it simply changes from one form to another. To keep a machine moving, the energy applied should stay with the machine without any losses. Because of this fact alone, it is impossible to build perpetual motion machines. Why? To build a perpetual motion machine we must accomplish many things: 1.) The machine should not have any "rubbing" parts: Any moving part must not touch other parts. This is because of friction that would be created between the two. This friction will ultimately cause the machine to lose its energy to heat. Making the surfaces smooth is not enough, as there is no perfectly smooth object. Heat will always be generated when two parts rub on each other (and that generation of heat is energy transference i.e, the motion machine losing energy). 2.) The machine must be operated inside a vacuum (no air): The reason for this has to do with the reason listed in number one. Operating the machine anywhere will cause the machine to lose energy due to the friction between the moving parts and air. Although the energy lost due to air friction is very small, remember, we are talking about perpetual motion machines here, if there is a loss mechanism, eventually, the machine will still lose its energy and run down (even if it takes a long, long time). 3.) The machine should not produce any sound: Sound is also a form of energy; if the machine is making any sound, that means that it is also losing energy. For the sake of argument, let's just say that somehow, we are able to build a perpetual motion machine. Will we be able to get energy from it? Yes, but only up to the energy that is used as an input to start the movement. A perpetual motion machine in real life will just be an energy storage. We must remember that the energy cannot be created; it always has to come from something. So, if you happen to be able to build one, you will need energy to start the motion. This is the only energy that you will be able to harvest, since, as stated previously, energy cannot be created. Kind of a pointless device, really.

When see the majority of the comments ,I have little hope, this will become a developed country. Most of the people lack in knowledge about physics and chemistry and believe these kind of machines save sri lanka.But we must appriciate the effort of Mr. Wikum puts on his inventions.

Eaka aththa...! Ancient Hela King Rawana used and flew the "Dandu-Monara-Yanthraya" using this principle. Nothing to do with Newton's Theories or any other theories of Thermodynamics or of Conservation of Energy. It works... It just works...!!
@@ashen1073 I'm doing my MSc in quantum mechanics at University of Surrey UK. The typical Newtonian physics you learn at school are not always objectivey true. There are many exceptions, like when it comes to quantum particles like electrons (which give electrical energy). So please don't dismiss someone based on your basic knowledge of physics. When you go deeper into the concepts you realize there are many more mysteries which conventional sciences cannot explain. Try to always keep an open mind.
