“Some of the fundamental laws of physics are so simple and obvious that no one doubts their justice, and no one is involved in their verification. In particular, this applies to Ohm’s law, according to which the direct current in the circuit (in any case at its low density) is equal to the voltage divided by the resistance: I = U / R. This is followed by other rules of electrical engineering. For example, according to the Joule-Lentz law, the heat W allocated to the resistance R is directly proportional to the voltage drop across it U, the current I and the duration of its passage t, that is, W = R-U-1-t. Therefore, if two identical resistances are sequentially included in a closed circuit, then the same amount of heat should be allocated to them in a unit of time. It seems quite obvious that, bypassing the first resistance, the electrons are not able to either acquire additional energy or lose it.

But does Ohm’s law really hold for resistances of all kinds at low current densities? Interested in this issue, I performed a series of simple experiments. Two, if possible, the same resistance, I included in the DC circuit, and next to them attached sensors sensitive thermometers. Each resistance, together with its “own” sensor, was placed in a separate thermostat.

In the first experiments, as resistance, I used incandescent lamps (calculated for a voltage of 2.5 V and a current of 0.15 A). Turning on the current (its source was a reducing stabilizing transformer and a rectifier included in a household circuit with a voltage of 220 V), I measured the temperature in thermostats for an hour; then changed the lamps in places and repeated the measurements. Five series of similar experiments showed that the metallic resistances gave off the amount of heat in full accordance with the classical laws of electrical engineering, and no matter where these resistances were located.

I did not make measurements using resistances of other types, but I performed the experiment using electrolytic cells as a resistance in which ordinary tap water was decomposed on stainless steel electrodes; the result again did not reveal any anomalies.

But if electrolysis of water was carried out in a porous, heterogeneous medium, the picture turned out to be different.

I filled the electrolytic cells with a mixture of quartz sand and tap water, acidified for better electrical conductivity by several drops of hydrochloric acid (which, generally speaking, is not necessary). And the first experiments gave amazing results, not corresponding to the classical laws of electrical engineering.

Namely, the temperature in the thermostat located in the course of the motion of the electrons turned out to be much higher than the temperature in the next thermostat! At a voltage of a current source of 220 V and its strength of 0.5 A, the difference was 90°C, which significantly exceeded the error value of previous experiments. In total I performed 10 similar experiments and noticed that the difference in temperature between cells clearly depends on the current strength in the circuit and can reach even a few tens of degrees.

I also noticed that on the first cell the voltage drop was higher than the second one (150 and 70 V, respectively), which explains the increased heat release. But the main question remained without an answer: why is there such a noticeable asymmetry, if before and after the experiments the resistance of the cells were the same? After all, this effect should not be!

It can be assumed that in the first cell the electrons for some reason lose some of their internal energy and therefore in the second cell they are no longer able to interact with ions as intensively. But in fact the second cell too (though not style strongly) heats up. True, in the sand-water electrolytic cells there are many local and rather sharp differences in the resistance of the medium, as a result of which the electrons in it are sharply accelerated, then they are sharply slowed down. Is not this the reason for the effect that I observed?

Of course, my assumption that after passing a certain device, the electrons can seem to get tired, giving the environment some special energy, contradicts the laws of nuclear physics, according to which the electron does not have an internal structure and has only a reserve of external kinetic energy. But if I’m wrong, then let me point out the error, preferably by repeating my experiments.

…The original idea of the experiment is an anomalous heat release in a granular medium. It turned out not quite what was supposed to be found, but still, the result is interesting. It looks as if the charge carrier, ions and electrons, interacting tightly with each other in the first cell along the current, lose some of their internal energy. And, of course, all this happens in an internally divided, more or less ordered environment.

Unfortunately, the lack of calorimeters, tools for accurate determination of the amount of heat released do not allow to receive data at a quantitative level. But the qualitative result is also a good result.

In the first approximation, the generator of electromagnetic energy can look like a slurry of magnetic microscopic balls in an external medium. According to all the above, the ordered array should periodically change its properties (and hence the magnetic flux) in time. It remains to add to it a coil with a wire to get a more or less perpetual generator.

In the case of a teapot, things are as follows. Let the table on which it is left to cool – a highly ordered structure of many identical elements, in a closed volume (it can be large). The energy of boiling water is first distributed throughout the volume. Then, macroscopic temperature fluctuations will arise in the system. The period of their appearance in this or that place can be calculated or even organized. We put the cooled vessel at the right time in the right place – and it boils.

This structure can work in an open space, attracting the energy scattered in the medium, raising it to the previous high level.

To such systems, undoubtedly, one can class living beings, beginning with the simplest unicellular ones. The body consists of billions, trillions of pores, membranes opening and closing according to a certain rhythm. For its life, it attracts more energy than it consumes when digesting food, which is proved by some scientific studies. Obviously, living, ordered matter is a kind of perpetual motion machine – however, not quite perfect yet. At the very least, food is needed for metabolism, cell replacement, and the like.

High orderliness is possessed by forest massifs, crops of crops, ice cover, possibly, deserts and dried salt lakes. Here, first of all, it is necessary to look for anomalous heat releases, and even radiation.

The energy (thermal, electromagnetic) that passes through the massif of matter evenly brings order into it. A standard example is the Benard cells, hexagonal honeycombs emerging in the oil layer on the heated surface. Thus, systems reanimating energy can be created, including a melt, from a solidification, under conditions of thermal energy inhomogeneity.
