To put an end to this topic one should conclude that while it was good to know there is such an attempt that attempt is sheer nonsense in addition to misunderstanding of basic concepts of physics. It has to be ignored outright.

        Hi  !

    A short comment regarding Dmitriyev's movie on net.

    His site is:   www.youtube.com/watch?v=FQ02MjqBk7s

    Really,he has no solution for a self-sustaining torque unbalance,on the same side of the fulcrum (the only one problem of a possible PM ),but there are,in my opinion,some interesting sequences:

      -a good fulcrum (0-14 sec.)

      -an useful up-down pendulum/eccenter free fall (23-30 sec.)

      -a practical free fall of a variable arm (40-62 sec.)

      -a limited rotation due to a starting torque unbalance (66-100 sec.)

    Regarding these test sequences of the movie,as valuable,maybe,we can employ them,to bring forth some new developments...the first step is to know,the next is to understand.

             All the best! / Alex

       -  Hi !

An additional plain comment about Dmitriyev's movie on net:

   -a good fulcrum is not sufficient: the friction must be "paid",anyway...so we must "minimize" the total weight,as much as possible.

   -if we want to remove out more useful gravity power,we must increase the free gravity fall ("torque avalanche" ),or the size,dimensions.

These two states of circumstances,require a simultaneous "mini-max" arrangement (see "Wheel vs. lever..." topic).

       All the best! / Alex

    Hi !

  The "key thread" of this wheel begins with Villard,Taccola,da Vinci...

  As a matter of fact ,this type of gravity wheel ("patented" by "dmfed" in Russia) ,is an old german "technical inheritance "(around 1712) :see "Maschinen tractate"/MT13 drawing.

  It doesn't work.

  Why?

  Read Bessler's bitter and deceptive comment about "greed"...

  Mikhail's "lesson" is that we can make easy simple tests,but a good starting point isn't a guarantee to finish this so long "marathon".

     All the best / Alex
