Perpetual motion machine on magnets?

Sometimes you look at the Internet pages, again and again ... And, sorry, you look exactly like a ram in front of a new gate. It seems that the yard is not the 21st century, but the 16th. The dawn of the era of humanity's transition from manual production to machine production. But the sensation is not at all the triumph of reason and science, but quite the opposite. Otherwise, the eternal engine on magnets would not arise again and again-an idea whose absurdity was repeatedly and convincingly proved.

Simplified to the bottom, the idea of any perpetual motion machine looks like this: some simple (or incredibly complex - depends on the imagination of the "inventor") the mechanism, once launched, works as long as desired. But since any other mechanism works by borrowing energy from outside (which is required by the law of conservation of mechanical energy), it turns out that the eternal engine is fueled by energy from nowhere.

The absurdity of this fact, however, is not so obvious as the impossibility of dividing the number by zero. Otherwise, how can you explain the fact that for two and a half centuries, poorly educated artisans and learned men have offered countless designs of perpetual motion machines, among which was the motor on magnets? And the impossibility of their endless work was constantly proved not only theoretically, but also experimentally! (At times, it came down to the construction of prototypes.)

Finally, in 1775 the French Academy of Sciences decided that henceforth the projects of perpetual motion would not be considered.

The "age" of this historical resolution is three centuries already. Do you think humanity has grown wiser? Judging by the "tutorials" on the sites "How to build a perpetual motion machine on magnets with your own hands" - a bit.

It is only worth reading the writings of the "inventors"! Here you and the new materials in the form of neodymium magnets, and homegrown "single field theory", and the proclamation of the knowledge of the school physics course is sufficient to build a perpetual motion machine. But that's what is typical: almost all the "inventors" devote a huge amount of their writings to the angry criticism of "pseudoscientists" who reject the "unique" perpetual motion machine on magnets. How they brand teachers of schools and universities, "clogging brains" and "zombie youth"! How do they sort out almost from the letter the answers sent from academies of sciences, institutes and laboratories, abundantly seasoning them with bilious commentaries. Immediately the reader is informed: it turns out that in Europe and America a perpetual magnet motor is already built and working. (No reliable reference, however, for some reason is not given.)

Worst of all, that all this pseudo-scientific nonsense actively multiplies and litter the search engines. Therefore, when you try to find scientifically reliable information about whether it is really possible to scoop up energy from nowhere and whether a simple perpetual motion machine on magnets will help, for example, to save electricity, "the unrecognized geniuses of all times and peoples" brazenly climb into the first lines of issue. And, even more sadly, liars and charlatans who collect donations for building their absurdity are many times more numerous than those who are sincerely mistaken. And, unfortunately, they believe ...
