Group: Experimentalist Hero Member Posts: 2072	I came across an astonishing discovery by Danil Doubochinski, which dates back to the Soviet years 70/80 and which seems to be little talked about despite a lot of perspective it opens up, not only in the macroscopic classical field, but also in the quantum field. The basic model is simple: it is a pendulum with a permanent magnet at the end. At the equilibrium position is placed a coil powered by an alternating current with a frequency of 50 to 1000 times the natural oscillation frequency of the pendulum Surprisingly, we observe: the pendulum always oscillates at a frequency very close to its natural frequency the pendulum synchronizes to an amplitude that is quantized, there may be several where the oscillation is stable the amplitude depends on the initial impulse given to the pendulum but not on the intensity of the current in the coil if the current is too low, of course the pendulum stops because it can no longer extract enough energy from the coil at each pass the pendulum adjusts itself to compensate for the losses, and is in phase with the electrical signal as it enters the magnetic influence zone of the coil several pendulums can be placed together that will synchronize on the current of the same coil, although each can have a very different natural oscillation frequency. https://www.youtube.com/watch?v=ZYx9QiK9Dp8 This could explain much more complex phenomena, such as the oscillations of the electronic layers around the atomic nuclei, or the synchronization of the planets of the solar system. It's not particularly the pendulum itself but the principle that could be interesting for us. The fact that the pendulum adjusts itself to the alternating current, and that there is no need for a reed relay or other passage detector to synchronize the current in the coil, but for a simple alternating current, is rather practical, especially since multiple synchronizations can be obtained. It's not a parametric operation, so it's new from my point of view. The phenomenon does not only concern the pendulum, but also electromagnetic fields (not yet deepened the question) or anything else, just use the equation m (d²x/dt² + 2.dx/dt + ω₀².x) = A.f(x).sin(ω₀.t) using physical parameters other than mass and distance ( f(x) represents the variation of intensity of the coil field around the central position). Douboshinski explains all this here: https://arxiv.org/abs/0711.4892 Erratum: I had mispelled his name ("~~Dubochinsky~~" instead of "Douboshinski").

Group: Experimentalist Hero Member Posts: 2072	Quote from: giantkiller on 2019-04-08, 17:24:05 Capture the harmonics... It is quite the opposite. The pendulum frequency is a sub-multiple of the current frequency. We must see each period of the current as a packet of energy that can be used by the pendulum as it enters the coil's area of influence. Then when it passes over the coil, no energy can be recovered because the signal is alternating, cancelling each other out in average value. We therefore understand that this possibility of energy extraction from the coil by the pendulum must be done with a precise phase of movement with respect to the coil and the current, requiring a pendulum period as close as possible to a multiple of that of the current, and that there are several stable possibilities especially if the frequency is high because then it is easier for the pendulum to find a period close to a multiple of the current period. However, the higher the frequency, the lower the energy of a period and the less easy it will be for the pendulum to discriminate the right period because we can have many of them in a short time, so in practice there is a frequency limit to the device. But the most surprising thing is still the pendulum's tendency to achieve stable movement, while the high frequency of the current would suggest that the vagaries of the phase relations between the pendulum and the current will cause random movements. [2019-04-10] This article is really the synthesis that should not be missed on the subject: http://www.21stcenturysciencetech.com/2006_articles/Amplitude.W05.pdf . It explains in simple terms the interest of Douboshinski's discovery, its key points, and what it can bring beyond the limits of Newtonian mechanics and Planck's quantum mechanics, towards which this article is very critical. He even gives practical advice on how to build such a pendulum (see the § "How to Build a Douboshinski Pendulum"). The perspectives of the system seem very interesting in our field, since it seems that an oscillating system can tune itself on another system oscillating at much higher frequencies (why not the atom?), to naturally draw energy from it. « Last Edit: 2019-04-10, 09:24:01 by F6FLT » --------------------------- "Open your mind, but not like a trash bin"

Group: Guest	Quite remarkable, at first glance I was tempted to believe that if the pendulum swings to its upper position it leaves the zone of influence of the AC electromagnetic field....but this of course is not so - it stays connected What happens is a parametric variation of the coupling-factor k of both magnetic fields. Graitiy is partly involved influencing this parametric variation of k which is sinusiodal The other factors are hard to visualize and very difficult to measure: Is the magnetic field component of the ac-coil modulated by the swing-by of the pm-field ? Are there fine-strucures building up within the ac-magnetic field which then synchronize to the different pendulum frequnecies ? How can we measure these fine-structures if so ? Spectrum-analyser ? No easy This has to be condsiderd while thinking about the configuration of other systems we might have in mind Mike

Group: Experimentalist Hero Member Posts: 2072	The influence of the coil is short-range, so the author only takes it into account when the permanent magnet is close to the coil. The magnet certainly induces an EMF in the coil, but if the circuit is well designed, for example in the form of an LC circuit, it will have a high impedance at the pendulum frequency, so the induced current will be negligible and there will be no feedback effect on the permanent magnet. As for the "fine-structures", I do not see what this is about. We cannot say that there is a real parametric effect. When this is the case, a parameter is artificially modified at the right time of oscillation, which introduces in phase energy into the system. Not here. With Doubochinski, we have a non-linearity related only to the functioning of the pendulum: when the amplitude becomes large, the oscillation period is no longer constant, it depends on the amplitude. The pendulum uses this fact to adjust its period with that of the coil signal, by modifying the amplitude. It seems that the quantization effect cannot be obtained when the amplitude is low so that the pendulum period is constant and equal to √(L/g). I put everything I found on the subject here: http://exvacuo.free.fr/div/Sciences/Divers/Douboshinski/ I discovered that despite his age, Doubochinski still seems to be active as scientific and technical director of the small French company "Quantix". The company seems credible, it is approved by the Ministry of Advanced Education and Research. It states: "A part of the scientific and technical team has already been set up, in particular with former students and collaborators of Dr Doubochinski". The company is looking for financing. They do R&D and apply the Doubochinski principle to vibratory phenomena, particularly for cooling effects with high efficiency, using pressure waves. « Last Edit: 2019-04-15, 11:22:32 by F6FLT » --------------------------- "Open your mind, but not like a trash bin"
