How does perpetual motion machine fits the principal of conservation of energy?

Perpetual motion would only fit the principle of the conservation of energy if it was a machine that moved that did not have any friction or produce any sound or produce any form of heat or energy that could be lost in any way. Since no such machine is possible to create, as far as we know, perpetual motion is declared an impossibility and does NOT fit the principle of the conservation of energy. Energy will undoubtedly be lost somewhere in a moving system.

If the efficiency of a machine is always less than 1 why is the principal of conservation of energy still obeyed?
Conservation of energy is not violated because some of the energy is always lost as heat (due to friction).
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.)
A time can come when you will be able to design a machine which can go on working for ever without the expenditure of energy is it possible?
Perpetual motion machines have fascinated people for centuries. However there are some scientific reasons, at least for now, that this would not be completely possible. Here's a deal: You get the law of conservation of mass/energy repealed, and I'll build your perpetual motion machine.
What is a machine that puts out as much energy as it takes in?
Such a fictional machine would be called a "Perpetual Motion Machine".
What law of thermodynamics states that energy cannot be created or destroyed?
The First Law is simply conservation of energy. It is impossible to create energy out of nothing, or to make energy disappear entirely.The First Law is simply conservation of energy.

How do you prove conservation of energy If you read Feynman's Lectures ch 4 what is meant by the whole reversible machine experiment?
a reversible machine is a machine which is in itself a perpetual motion machine I am guessing.

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.

Why cant there be a perpetual machine?
It isn't entirely clear what you mean with "perpetual machine". If you mean the old dream of the "perpetuum mobile", such a machine would violate the Law of Conservation of Energy; there are various reasons to assume that this law can't be violated:* Despite lots of attempts, by thousands of ingenious inventors, and over centuries, nobody has managed to violate Conservation of Energy so far. * Violating Conservation of Energy would also violate lots of other laws of physics, which are generally considered to be true. For example, Conservation of Mass, and Conservation of Momentum. * By Nöther's Theorem, the possibility that the amount of energy changes over time would be equivalent to the laws of physics changing over time! - Nowadays, the Law of Conservation of Energy is normally derived from Nöther's Theorem.
In what way is a machine subject to the law of energy conservation?
The law of conservation of energy was never found to be violated. The relevance for a machine is that a machine can not produce more energy than is put into the machine.

From time to time people claim to have invented a machine that will run forever without energy input and develops more energy that it uses Why would you have reason to question such a machine?
Friction and entropy overcome all devices eventually. DaVinci called perpetual motion a shimia. A ghost or illusion.Answer2. Such a machine would violate Conservation of Energy, creating energy from nothing.The Second Law of Thermodynamics.
