Big try at gravity wheel

[PiCéd]

I don't know but I wonder if they do the confusion with electrostatic, to see a big trick like that if it realy work it is not by the gravity.

@lota: nice try, I like the idea to use "meccano".

Here I identified the patent which is most likely relevant: http://www.overunity.com/13480/big-try-at-gravity-wheel/msg359666/#msg359666

But you might know that already.

The most important question is whether they need a motor to run the machine. I would be more inclined to believe in the machine if it only needs a motor to be started and then takes over by itself.

If the machine needs a motor constantly it will be a difficult case of establishing good input/output measurements and people will argue forever.

I've been following this for months, and trying to figure out how it works. I think I can see the principle:
- The position where the weight is carried on the down / up strokes is different.
- The linkage to the weight changes from the 'arm', to the 'big silver bearing'
- On the down stroke - the weight is held via the arm
- On the up stroke - the weight is held by the bearing

- It is not a 'soybean crusher', or any other kind of normal machine, that's for sure.

If it's a hoax - it's a very expensive, kinda pointless one.

The Renato Ribeiro mechanical motion energy generation machine
A viewpoint
The system principle applied in this machine by Renato is very well thought out and many working details can be discerned from the detailed photo's presented. I thank the designer for sharing his brilliant mind with this innovation so we can al advance in knowledge to the benefit of mankind.

System shown
What Ribeiro showed in his picture is that the (large) system is an evolutionary flow of refining this larger version model. I would guess that it is to a certain degree different to the initial "prove of concept" model. We need to keep in mind that the construction scope changes dramatically when you need to move heavy weights at a certain rapid speed. Moving unsymmetrical weights at some speed is no easy matter. Remember energy quantity is proportional to force(weight) & distance per time unit. The "per time unit" is speed or cycles per minute.
The American model shown to be build appears to be the same than the latest (improved) Brazilian model.

The overunity approach
The required concept for any over-unity system is to have a greater energy return than what needs to be provided to keep the system cycling.  Therefore, the energy to lift a weight must be smaller than the energy returned during decent or said differently, the return energy must be bigger than the lift energy. This can not be done by a straight forward linear physics process as the symmetry of standard physics prohibits this.
Therefore the process choosen between lift and descend has to alter so that the equation is no longer symmetrical, to do this a different natural aspect must be applied between the up & down parts of the cycle ( the physics presentation must be different to get a different outcome).
You basically need for an OU system to mess around with the physical process so that the "up" formula is different to the "down" formula (to achieve asymmetry). This messing around should not cost you more that you can gain, because we aiming to achieve a positive outcome balance sheet.  This is were innovation is required.

The Ribeiro overunity principle used
The principle used by Ribeiro to achieve energy gain is as follows (and I am open for possible correction and other viewpoints).
For the system to work, the upstroke should take less energy than the down stroke. To achieve this, the weight is levered down using a ~2x lever advantage. The weight is lifted using a 1x lever advantage. The travel height for the weight in both strokes is the same and this is where the advantage / gain is (and Ribeiro ingenuity was applied)

1.. Weight down stroke uses the extended lever effect (~2x distance x weight, being the parallelogram (roberval) and triangle distance from the fixed frame hinge)
2.. Weight up stroke uses the Roberval principle (~1x distance x weight, the triangle becomes part of the vertical roberval beam)

I would guess this gives the system a ~1x weight x distance energy gain advantage, it will depend on what the RPM the machine is capable off for how much energy it can deliver. (the reason for the multiple modifications).
The ingenuity is in the mechanical method used that changes the setup between up and down stroke. 

As you might remember from a previous tread where TK and others had a fall-out with Wayne Travis because they couldn't see the point, It was the same principle used by Wayne Travis in the Hydro ZED, using a differentiation process between the up & down stroke of his hydro ZED system in order to create asymmetry and thereby to work around the standard physics limitation. A changed lever between up & down strokes but UNCHANGED travel height. It is difficult for many people to see the subtle principle but necessary difference that is applied here.  It requires some persistent visualization to swing your head around the concept.

As a pointer for this invention, you must have wondered by now, what is that triangle doing there mounted with these big silver shine flanges and do pay attention to that complete assembly interactions with the robervall.

SALUT to the inventors of the new world, for the shared knowledge that provides us great inspiration
