Gravity wheel of Mikhail Dmitriyev

[gdez]

 There is a lot of smart, ambitious people on to the free energy movement, and more coming over everyday. I've only been into this free energy suff for about 2-3yrs and it seems that things are moving faster and faster, improving everyday. Just compare it to the egypt thing, when there is enough of us, there will be no stopping it. Just a matter of time.

One of the problems with understanding this device is the fact that stuff gets lost in translation . For instance in the Peswiki News article is the following quote . "For pushing of the weights ,requires a small amount of energy .BELT AND GEAR ON IT IS JUST NOT CAPABLE . I take this to mean that the self looping method with the chain drive was a failure . Was this due to a lack of power from the wheel to displace its own weights , or were there engineering problems beyond the capability of the inventor to solve . we are not told .
      Then we are shown some diagrams , presumably from the patent specification . These appear to show the weights being shifted by fixed stationary ramps . This method has been tried a thousand times , and failed [Basically Archer Quinn revisited .
     The device is described as a torque amplifier  . Not a power amplifier or an energy amplifier . I believe a simple reduction gearbox is a torque amplifier , and am more than willing to be corrected if wrong .
    No attempt is made to measur input and output . there is no load , generator or Prony Brake .Without these the whole device becomes a very inneficient slow speed electric motor [5% efficient?] please DISCUSS .

@neptune,
I had the same question about the chain thing and , I thought "why didn't he get the thing going with the small motor, and then just switch from battery to generator?" He seems to have the building skills to do that. And it seems that if his claims were true, he would have seen that right away. I'm not going to write him off just yet, but it seems like he's definitely getting a little far ahead of himself. I'm looking forward to seeing someone credible do a replication, and I can think of a few people that could probably build one of these things in 1 day. One thing i'll give Dimetriev is he seems to have confidence. If I had built one that has his claimed input/output, I think I could have done a more convincing video. What about this 4 stage 50kw one he talks about? I might have went with a video of that. Well, anyway I wish him luck and I'll be watching.

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.

Non-sense. 1) Hamilton's equations apply in whatever chosen referential frame. 2) "The system must be at rest" is a statement without meaning if you don't say in which referential (a system is always at rest in its own referential).

I wonder if someone will finally realize that a given weight which is limited to a fixed difference in altitude will not be able to do work. Whatever we try do do in order to make one part of a gravitywheel to work, will do the exact opposite action - trying to stop the wheel. Gravity cannot do work, because it is a permanent force, in one permanent direction. "Permanent" means "no change". No change will ofcourse not do work.

"Drinking birds" is the closest we can get a working gravity wheel - by using the same principles:
