Big try at gravity wheel

[tim123]

Hi Red_Sunset
  I'm glad I invested in the meccano... I bought a job lot on ebay a few years ago, and it has served me well.

It's often easier to build things than to simulate them. I appreciate you taking the time to do the drawings. It has clearly helped you further your understanding, and if you think you know another way it might work, let us know...

I'm beginning to seriously wonder if the guy built the machine without prototyping it. It did go thru a load of modifications, and all the 'tweaks' they've added - well... Were they to improve output, or were they hacks to try and get it to work?

The fact he's building another tells us nothing at this stage. Until #1 is running and proven... I'm still mystified.

Ribeiro Patent Application text
[0046] The force of gravity exerted over the weight is trans ferred to the assembly through the central shaft. This shaft, depending on where the locks are exercising the support, if they are on the positive or neutral arms and when, transfer more or less force to the blue bar. This in turn transfers the force to the crankshaft arm that is transferred to the crankshaft where the torque is applied.

Can this statement be true?

The positive bars are the horizontal arms and the neutral bar is the vertical arm of the 1/2 Roberval.    The central shaft is the hinge at the bottom of the vertical roberval bar.
The overall total weight (roberval + Triange weight bar + weight hanged) is supported by the blue bar that connects to the crankshaft. The weight would be a vertical down force.

Question: How can this weight change depending on how the weight triangle connects to the roberval?  by means of the arc locks.

We do have an horizontal force imposed by the arc lock on the blue connecting rod to the crankshaft, this force when in the same direction than rotation would aid rotation. But to my observation, it would be counter for 1/4 turn and then aid for a 1/4 rotation (this is approx), so not sure if this could be the essence of the statement

Any idea's ?

Tim,
Do keep in mind, the objective of what the guy is building is to get orders. He is in business to make money.  I don't think he is still trying to prove anything, only to get a good working demonstration going.

So long you have a good sound principle, the rest is just a matter of engineering.

From what I can deduct, he has done his homework.  Sure there are always newer and better idea's that come along. What I think he is doing is trying to improve the energy density. This will in the end determine the investment cost per energy unit. And make the system more attractive.

The working of the system should be clear (apart from some details), from what has been said in previous mails, or isn't?

Hi,
     looking at this from the point of view as a mechanical device I would guess that a 20 kw
motor would get it to turn over fairly sedately.
  There would be a massive amount of loss due to friction of bearings and sliders, also if any
speed was obtained inertia would become involved and the thing would soon shake itself
to pieces.
   You would probably need to find a couple of million ft/lbs per minute from somewhere for
it to go by itself. In theory I suppose that as some weights go down they would balance the
ones that are rising. Where the excess would come from is a mystery.
   Where is The Koala when he's needed? Hibernating? I really would like to see a successful
outcome here so I'll keep on watching and hoping!
  From the investment point of view I would guess you could buy a 30 kw genset and run it
a good few years on what this machine would cost to build,house and maintain. I can't see
it running for that long before major problems started.

Hi

Red_Sunset, It is useless to think (reflect) about the system RAR energia.

I still repeat :

The machine does not exist. The workers are false.
All the images are forged. Everything is false



1 ) Supporting evidence :

Official text RAR energia Ltda : << Another similar equipment will be built in the U.S.A. at the Incobrasa Industries Ltd plant, a Company of the group, located in Gilman, IL. >>

But...
Update Google Maps by Digital Globe USDA Farm Service Agency, October 02nd, 2013
Official satellite picture : July 09th, 2013

The address of Incobrasa Industries, Ltd : 40°45'46.85"N  88° 0'44.25"W
The green arrow should show the building : Here

That's odd !!

There is no constructed building ( Second picture )
