When is a machine not perpetual motion? When it can be convincingly explained! Eureka!

Are perpetual motion

machines possible?

 

So, at 3:26, if something is called a perpetual motion machine, then this implies that it can't be explained how it works, because it doesn't use any Laws of Physics, and thus does not work outside of fraud or trickery. Instead, it uses hyperbole by its creator or promoter to make up for solid analysis? So, all I have to do, or anyone else for that matter, is be able to explain why something "appears" to be a perpetual motion machine, but actually isn't, merely because it doesn't defy any Law of Physics (such as the Drinking Bird Toy example), because it can readily be explained in terms we already know from having studied Physics, Thermodynamics, Electrical Engineering, Chemistry, Mechanical Engineering, etc? So, this use of the term: "perpetual motion machine", by Physics Girl, helps me to understand why so often this term is used in my face by (sometimes) not very friendly people whose patience has worn so thin, that any discussion of "apparent" perpetual motion machines never gets started, or maintained for very long, simply because no one has thoroughly, nor accurately, analyzed any candidate machine for either debunking it or explaining it - and so, consequentially, it does not exist as a true machine, but merely exists as an artistry of magic and imagination? Whew! I feel much better, now, because I understand that just because some machine is called "perpetual motion" does not make it so. In fact, it is our collective misuse of language that perpetrates this dilemma. So long as a machine can't be explained, so long is it a candidate for perpetual motion, but still not yet a fully-fledged, bonefide perpetual motion machine. In other words, a non-perpetual motion machine is a definitive machine while a perpetual motion machine is not. All we've managed to do is define what a machine is and exclude everything else which lies outside of our collective ability to define machines. A perpetual motion machine's only flaw is that it has yet to graduate to the status of a true machine and specific instances of "apparent" perpetual motion have yet to be explained. Well, it's back to the drawing boards and the study of basic and advanced scientific theory...
