B One magnet motor that does not break any thermodynamic rules

  1. Feb 3, 2017 #1
    I am wondering how efficient this engine can get, I am thinking if one used a superconductive magnet that is really strong?

    Questions for you:

    1) What is Thermal/Thermo avout this mechanism?

    2) It appears to be a simply synchronized weak motor. What am I missing?

    3) Superconducting magnets in motors could be more efficient. Why aren't they used now? (The answer is not that scientists and engineers are missing something obvious)

    This looks about as efficient as the bobbing duck engine

    My first thought is that the magnetic saturation of the nickel is likely a more limiting factor than type of magnet.

    The third question; Today its neccesary to use liquid helium to get a superconductive to work.

    Correct! Yeah, not very practical for most motor application... :smile:

    Interesting. Too bad the energy conversion efficiency is so low, but still an interesting mechanism for some situations...

    Maby this type of engine can bee used to power a very smal generator to load a mobilphone where there is no electricity available? Maby at night when solarcells does not work?
