A machine that keeps going and going without any sort of external power.
If you manage to invent one you'll become a very rich person.

A perpetual motion machine is a machine that will continue running forever without any kind of external power supply. It goes forever because it never loses any energy to friction.
No such thing has ever been made because no one has been able to make a completely frictionless machine.

It defies the laws of physics because energy has to be lost through movement and friction hence perpetual motion is not possible, although it hasn't stopped people from designing some pretty imaginitive machines.

A machine that does not use any external power, batteries, atomic power, solar power, etc. It just runs forever just using the natural forces, magnetism and gravity.
It is impossible to make.

Theoretically it is a machine that has no internal resistance and uses a much power to run as it produces so that once started it will run on its own power forever.

A fantasy, because you'll never overcome friction.
It's a device that can sustain it's own movement once it is set in motion. They don't exist.

If you believe in evolution, the universe is one.......
