How to make a perpetual motion machine?

The question of creating a perpetual motion machine excitedman, perhaps, from the very time when the ancient savage ran out of wood in a fire and he was too lazy to follow new ones. He began to dream, "Now if one log burned forever ..." Such an eternal branch is an abstract example of a perpetual motion machine. Modern people, far from savages, still think about how to create a perpetual motion machine. And if you leave out specific examples, the perpetual motion machine is some system that does more useful work than the amount of energy that was reported to it. And if we transfer part of the output energy to the input of the same system, we get the engine running without fuel, in other words, perpetuum mobile of the first kind.

Early attempts to create

For centuries, manytheoretical hypotheses, how to assemble a perpetual motion machine. The earliest mention is the idea of ​​the Indian mathematician Bhaskara, a wheel with obliquely fixed flasks, not completely filled with mercury. According to the laws of the lever such a wheel due to the rolling of mercury through the flasks had to constantly rotate. The idea itself did not justify - those flasks where the mercury is closer to the center of the wheel, it turned out more, and they balanced the rest. The wheel did not even move. After it there were jagged wheels with loads, a flask of water, which was supposed to constantly push out the light body and rotate the generator, but everything was in vain.

Theoretical rebuttal

The basic postulates of physics are thatthe existence of such a machine is impossible. This is what the first law of thermodynamics, formulated by physicists in the nineteenth century, affirms. And really, if you think about it - a perpetual motion machine constantly spends energy, doing work. But to him the energy from the outside does not come from - there is no fuel. And it turns out that energy is extracted from nowhere. And the impossibility of such is the law of conservation of energy, one of the theses without which our universe would not exist, or, at least, it would be arranged differently. After all, nothing is created from nowhere and nothing disappears without a trace.

Current state of affairs

Today, the World Wide Web hasa lot of video instructions, how to make a perpetual motion machine at home. But all this is cheating and staging. In any, even the most impeccable at first sight project of the perpetual motion machine there is some nuance that will turn all the advantages into dust. Of course, you should not leave it completely. Despite the fact that the perpetual motion machine or its similarity has not been created, the result of attempts has been several models of pseudo-motors, which, although they did not take energy from nowhere, but worked with a high coefficient of efficiency. In other words, very little fuel was spent on the engine itself, most of the resource was spent on useful work. A fuel-efficient engine is, of course, not perpetuum mobile, but it's also not bad.
