Muggle train of its own design may appear in Russia


Levitating transport could well become the system of movement of the future. High speed, economy and the complete absence of harmful emissions make this technology extremely attractive, especially in the current realities, where the fight for the environment is gaining momentum.


On the eve of the Russian scientists also contributed to the development of a promising transport system. MEPhI specialists conducted a thorough study of the physical mechanisms of magnetic levitation, the results of which will significantly expand the prospects for the use of high-temperature superconductors in the creation of new engines, bearings and kinetic drives.

Experiments have shown that in addition to the complete absence of resistance to electric current, superconductors have another unique property. The material pushes a magnetic field out of its volume. In turn, this means that a magnet placed above a tape from a high-temperature superconductor will not fall, but will levitate at a certain height. In addition, such a “magnetic transport” will not be able to go off the rails during movement, since the tape and magnet will literally be “tied” to each other due to the quantum nature of the superconducting state.

According to the professor of NRNU MEPhI Igor Rudnev, experiments using high-temperature superconductors have clearly demonstrated the unconditional promise of using the material in magnetic-levitation systems. In the near future, Russian scientists intend to apply the results obtained during the study to create maglev, magnetic bearings and superconducting motors.

    RUSSIA is big, and we really need such trains and such technologies! Only our oligarchs will wait for the state to build, and then privatize.

    In RUSSIA you need to live a long time in order to survive to a good one!

    Trains are needed, yes.
    Maybe aliens will come and build them for us ...

    Superconducting levitation based on the Meissner effect is expensive. Transport should be cost-effective. A different approach is needed here. There are prerequisites for this - they are embedded in Maxwell's equations, however, in a different form of representation, expanded. Muggle technology becomes purely electrodynamic (in the classical sense), with the possibility of levitation at zero speed and without the need for any magnets or superconductivity, which leads to a significant reduction in the cost of the motion control system and the maintenance of the track web. This is primarily due to the fact that the rotor part placed in the track web can be made of aluminum, like a squirrel cage rotor of an asynchronous machine. The main difficulty in creating the required electromagnetic fields is transferred to control algorithms, which at the current level of development of digital technologies will not cause special difficulties. It is possible that this particular alternative will make it possible to obtain an acceptable level of profitability of the Muggle and it will open its doors wide for those who wish to fly above the ground. To confirm or refute this, experimental research is needed, as they say, the devil in detail. So the thing is small - start ...

        There are currently 3 magnetic levitation technologies:

        1. Electrodynamic suspension EDS with superconducting magnets
        (JR-Maglev, Japan);
        2. EMS electromagnetic suspension on electromagnets
        (Transrapid, Germany);
        3. Inductrack Permanent Magnet Technology Halbach array
        (HyperLoop, USA).

        The video shows the project "Russian Maglev". By technology, it can be assigned to the 3rd group. Each of the technologies has its advantages and disadvantages, but all of them, as practice shows, are unprofitable. In muggle, a combination of 2 systems is implemented: levitation and movement. The second, as a rule, is a linear electric motor. Most likely, the achievement of profitability is associated with the organic combination of these systems.

    1. "... complete absence of harmful emissions" - nonsense. Electricity, and a lot, is generated by friction of your pants?
    2. "... superconductors" is the key word. Industrial applications are questionable even in the near future. There is no available and inexpensive technology to maintain the superconductivity parameters yet. You can create an advertising demonstrator for several kilometers and trumpet people in the ears about environmental friendliness, but it will come out as with alternative energy in Europe - without significant government support, it was and will be unprofitable. You will overcome technological limitations, then come with projects.

    Another blah blah project. Like, in the USA, China, Europe and Japan there will be - let's blah blah too ...
