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

I've created a feature page on this here: http://peswiki.com/index.php/Directory:Mikhail_Dmitriev_Gravity_Wheel

Mikhail Dmitriev Gravity Wheel - This Russian inventor has been developing gravity-based power systems for years and says that the design has been widely replicated in Russia, even powering some houses. He says he has posted all necessary information to build the device, in which a small amount of power input generates much greater power output. (PESWiki; January 30, 2011)

I also created an animation.

This is not a dream, this is a reality.
All  procedures that you mentioned I have  realised, they already passed  and  done :
- the working model exist;
...

Where is it? We have to verify it.

Wm2d works according to the laws of physics. Therefore it is impossible to simulate a perpetual motion, except by setting conditions with unphysical parameters or by exploiting software bugs (every one having played with wm2d knows that it is possible to modelize virtual pseudo-perpetual machine using the software holes).

I welcome anybody who's keeps their work open source & non-commercial. Dmitriev deserves both my respect & benefit of the doubt when it comes to his claims.

Every time it seems I think of replicating an overunity device, one more pops up that seems all the more appealing. Yet I can't help but wonder, if I were to put this in my car, which direction would the ratchet go best: to get energy from accelerating, or decelerating? Why does it always go back to cars? ::)

Therefore it is impossible to simulate a perpetual motion, except by setting conditions with unphysical parameters or by exploiting software bugs (every one having played with wm2d knows that it is possible to modelize virtual pseudo-perpetual machine using the software holes).

Wm2d uses constraint based physics, constraints rules are used throughout the simulation to continuously modify velocities and position. One of the main constraint is energy conservation. So wm2d will never show you a violation of conservation of energy if you use rods and pins unless the simulation step size is not low enough.

The only way to verify it is in a real lab.

What is odd is that that video is from October. Surely someone so sure of his design would have built perhaps a better one which does take the power out from the big wheel. It's one thing to show a spinning wheel using a motor, but another to speak of output numbers when there's no generator in sight.

@broli,

While I do agree that to overturn the existing perceptions in science that CoE is inviolable a working perpetuum mobile, replicable by independent parties has to be demonstrated, that is only because of psychological reasons characteristic for the society we live in. If it were for pure scientific reasons, there are already sufficient arguments categorically proving that CoE can be violated even for reasons inherent in the standard theory. Unfortunately, the scientific method is only paid lip service nowadays.

Here's another example of inherent violation of CoE in the standard theoretical physics. CoE in a system is stated by H = T + V = const where H is the total energy of the mechanical system, T is the kinetic anergy and V is the potential energy of that system.

Further, according to the most general equations in classical mechanics, namely, Hamilton's equations, we have partialdH/partialdpi = partialdqi/partialdt and partialdH/partialdqi = -partialdpi/partialdt where pi is the generalized momentum and pi is the generalized coordinate and t is time.

Form the above it follows directly that partialdqi/partialt = 0 and -partialdpi/partialt = 0. Therefore, qi = const and -pi= const.

In other words, in order for Hamilton's equations, which are the equations of motion (that is, equations valid for v =/= 0) to be in effect for a conservative system that system has to be at velocity v = 0, that is, the system must be at rest. Thus, in order for CoE to be in effect the most general equations of motion in mechanics require the system to be at rest.

As seen, the basics of theoretical mechanics don't comply with its own CoE requirement when the system is in motion.

This is just one more example of the fallacies the science ruling today is subjected to. To keep them from becoming widely known there is vigourous propaganda and suppression which knows no limits to intimidation, mockery and manipulation.

@Omnibus .Very interesting post , but could you please state categorically if you think this device is a fraud , or if you think it could work . If you look at all the videos in The article posted in Peswiki news today , you will notice that one version of the device does not have a drive motor . The "flails" that swing the weights are powered by a chain drive from the shaft . This is interesting , because it is obviously an attempt at a looped self runner . If the device is , as claimed about 200% overunity , this could work because a chain drive in good condition can be better than 95% efficient . If that leaves even one watt to spare as output , then we have cracked it . For replicators , there are at least two alternatives to the expensive one way ratchet bearings . One is , cheap ratchet spanners . the other is a bicycle rear hub with freewheel sprocket . If you want to attempt the motor drive version , a car windscreen wiper mech contains a motor with suitable reduction drive gearbox.

I don't know if it's a fraud or not but the whole approach here seems very similar to all these Kapanadze's, Torbay's, Abeling's and what not, trying to wet the appetite of gullible investors or to make others make it (for lack of own funds) and then claim it and so on. If it's a self-runner the guy should go out of his way to help other parties reproduce it. So far I consider it void of any merit as an OU device. The ball is in his court. If we need a "brute force" device with minimal input energy we already have the one by Paul Sprain. That's the best I've seen so far and yet he still needs to not only prove it really is OU but to make it self-sustaining.

Suddenly I smell Bullshit . AS described in my last post , one version has the weights moved by a device chain driven from the shaft . This version obviously failed to work , because if you look at one of his motorised versions , it still has that same sprocket mounted on the main wheel shaft . So why would he dismantle a self sustaining version in order to make a motorised version? That would make as much sense as destroying some diamonds to get carbon to make carbon brushes . He claims that several Russians are powering their homes with it . So why wouldn't one of them bring this technology to Europe and try to make a fortune with it ? Enough Russians find the money to come here to take low paid jobs . If it smells like bullshit it is bullshit . No exceptions . The guy is either deluded , or for reasons beyond me , is lying .

@neptune,
 I really like this idea, but like you I am sceptical. For the output claims he has made to sterling, I would have to ask, "where's a video of one that's powering a house?". I think we'll see soon though, because it does look easy to build, and I'm sure someone will replicate soon. On a positive note though, He is open sourcing and seems to not have anything to hide.

@gdez . No one wants to believe this is real more than I do . But wishing does not make it so . Free Energy is not a religion , but is in danger of becoming one . That way lies madness . As always we must wait and see , and wait and wait...
