can ne1 tell me abt de workin principle of perpetual machines???

Question

can dis generate electricity?cost of generation?weder pract possible...???

Answer 1

*Perpetual motion machines are a class of hypothetical machines which produce useful energy "from nowhere" - that is, without requiring additional energy input. Specifically, perpetual motion machines would violate either the first or second laws of thermodynamics. Perpetual motion machines are divided into two subcategories defined by which law of thermodynamics would have to be broken in order for the device to be a true perpetual motion machine. No genuine perpetual motion machine currently exists, and according to certain fundamental laws in physics they cannot exist. The history of perpetual motion encompasses not only energy-creating machines but also methods of exploiting nonobvious power sources, methods, and techniques and devices with no energy loss (or output). This timeline covers those and the discoveries of energy from sources that are "free" (i.e. does not cost anything) for consumption from the forces of nature which are well documented in scientific literature and other more fantastical forces. Perpetual motion machines, when hypothesised, are sometimes called free energy machines, though the term energy in that circumstance is being used in a sense outside of the scientific definition. Some are developed with elaborate machines in the style of Rube Goldberg or Heath Robinson. Some designs may appear to work on paper at first glance, but have various flaws or obfuscated external power sources that render them useless in practice; others remain untested.
*Perpetual motion refers to a condition in which an object moves forever without the expenditure of any limited internal or external source of energy. For example, electrons in an atom or quarks in a nucleus are in a state of perpetual motion. As well as being descriptive of motions beyond the scale of human lifetimes, for example in the phrase "the stars in perpetual motion wheeled overhead", the term is commonly used to refer to actual attempts to build machines which display this phenomenon. In the macroscoping world, perpetual motion is not possible, because the energy of a particle tends to randomly flow into its neighborhood, such that the original goal of producing an ordered work is lost.

Answer 2

You could create a machine that taps energy from the tides or the wind, but it's no longer a "perpetual motion" machine.
The term perpetual motion, taken literally, refers to movement that goes on forever. This is possible in the current theoretical understanding of physics as in Newton's First Law of Motion. However, perpetual motion usually refers to a device or system that stores and/or outputs more energy than is put into it. Such a device or system would be in violation of the law of Conservation of Energy, which states that energy can never be created or destroyed, and is therefore deemed impossible by mainstream physics. The most conventional type of perpetual motion machine is a mechanical system which (supposedly) sustains motion whilst inevitably losing energy to friction and air resistance.

Answer 3

No. - There are many scams out there,
but no real perpetual motion machine.
Total Energy in always = Total Energy out,
and there are always friction or other losses,
so if your told it's perpetual motion, you are
being lied to.

Answer 4

perpetual motion machine are a big skam you can't create energy unless u have a nuclear explosion

energy put into machine is lossed by friction. thus energy in is greater then energy out. check out friction gibbs free energy loss do to enthalpy and entropy

Answer 5

the laws of thermodynamics strictly prohibit this concept. The effeciency of the machine will always be less than one, thus you will have to put in more energy than you would ever get out.

Answer 6

perpetul machine work on a principle of electricity generating devices it can generate electriciy it works on a principle of nozzle devices. it can produce large amount of electricity with low cost of manufacturing.
