Perpetuum mobile and free energy

If you use the Internet to type the phrase "perpetuum mobile with your own hands" in the Google search box, the search engine will helpfully display a very impressive number (over 75,000) of various results, including pictures, detailed instructions and videos with the work of existing models. And although attempts to repeat the "success" of many authors at home always end in complete failure, this once again confirms the stubbornness inherent in human nature, which in no way allows a man to accept the action of the immutable laws of nature and makes him look for inexhaustible sources of unlimited energy.

In history, the perpetual motion machine is first mentioned in the poem of an Indian astronomer, mathematician and poet Bhaskara, which dates from about 1150. So, India can rightfully be considered the ancestral home of the first perpetuum mobile models. This poem describes a perpetual motion machine in the form of a wheel with obliquely mounted on the rim of narrow, long vessels that are half filled with mercury. The difference in the moments of gravity, which created the fluid moving in the vessels, was to make the wheel rotate constantly. But it was not possible to circumvent the laws of nature.

From that moment, the man's imagination constantly led to new ideas. However, instead of simple mechanics, modern inventors now offer Use electricity, magnet or gravity. For example, a magnetic perpetual motion machine involves placing around the circle of small magnets and exposing them to the magnetic field of a separately located magnet. According to the plan, repulsion of the same name and attraction of opposite poles of magnets should make the wheel spin without any interference from outside. But in reality this does not happen, otherwise long ago everyone in the apartment would have a similar unit.

It turns out that, no matter how much a person wishes, the eternal engine of any, even the most complex construction, contains flaws and does not work. And all because the principle of his work violates the first or second law of thermodynamics.

In 1775, more than two centuries ago, in Western Europe , the most authoritative scientific tribunal of that time, the Paris Academy of Sciences, opposed the belief in the existence of a perpetual motion machine. Already at that time, many well-known scientists have led many irrefutable proofs of the impossibility of perpetual motion. Around the middle of the 20th century, this fact was recognized by the Patent Office of the United States, exhausted by endless applications.

Nevertheless, there are still people who say that they invented another model of perpetual motion machine. As a rule, these are scammers who try to make money out of gullibility and ignorance of the laws of thermodynamics. However, it is possible that among these people there will be a new genius who will still come up with a compact eco-engine capable of extracting energy from the surrounding world in such volumes and with such a long period of work that it can be called "eternal".
