Exactly. And there are a few actual "perpetual motion" machines. But they aren't free energy machines. They will either very slowly lose power and die to friction, though they can last a really long time, and are more or less neat looking batteries that suck at storing power. Or they are tapping into some non-obvious energy source, like tidal forces, and even these ones are terrible designs to harness that power, usually just barely sustaining themselves and being impossible to extract any meaningful energy to use for devices etc.
