The idea of perpetual energy is that converting one energy source to another would have at least a 100% conversion rate. For example, say you have a machine that uses 50 watts to produce 150 watts of electricity. That is a 300% conversion rate. This is impossible because in that scenario, 100 watts of electricity was created. The laws of physics (conservation of energy) states that energy is not created or destroyed, it is only converted into another type of energy. You can't even convert energy at a 100% rate of conversion, because another law of physics (the first law of thermodynamics I believe) states that whenever energy is converted, some amount of energy is converted to heat. You can prove this by rubbing your hands together, or you could touch a light bulb that has been on for hours, it will be hot. For these reasons, perpetual energy is impossible, you will never be able to create energy, or even retain 100% of it when converting it.
Perpetual motion machine is impossible because of the loss of energy due to friction or some other factors. This becomes clear in case of heat engine too. Certain amount of energy will be lost in irreversible way. Hence perpetual motion becomes impossible.

Perpetual motion is impossible if there is any friction, or any other removal of linerar or angular momentum.
From the second law of thermodynamics, "It is impossible to convert heat completely into work in a cyclic process." Thus, energy in a system is gradually lost. Because of this, the energy will eventually run out (though it may take a very long time), and perpetual motion is impossible.
A perpetual motion machine of the first kind it what we usually mean by a perpetual motion machine. A device which once started will continue to run and do useful work forever without the need to add energy to keep it going. The laws of physics make such a device impossible.
A perpetual motion machine has been deemed impossible by physics; the US patent office allegedly will not consider applications claiming perpetual motion.
Theoretically it is impossible. Many have tried and many continue to attempt to develop a perpetual motion machine. Only if there is no friction and no energy is lost to the surroundings, would perpetual motion be possible... No. Such machines are not possible, although until the end of mankind people will perpetually try to imagine or create one.
No one. Perpetual motion has not been invented yet.
Perpetual motion machines are theoretical only. No one has actually invented one. A perpetual motion machine would have to be able to provide its own source of energy to continue operating.
People would like it a lot, if it existed. Perpetual motion is impossible: a whimsical fantasy of ignorant fools who ignore the laws of physics; and as such anyone who mentions the possibility of perpetual motion existing is considered an idiot.
There is no answer to your question because a perpetual motion machine is impossible. If one could be built, its own motion would be considered work.
it isn't, the trick is to use technology that doesn't cause friction - kind of like what's found in the computer you are now using to read this - that's the only clue I'm giving you!
