I have got a crude 3d-model (3ds max) that actually seems to work.
Tonight I'll let it simulate a couple of minuttes and upload the video for you. (Should be in about 10 hours from now)
There's no other force-input but gravity itself.

It's the simple hockey-stick model with 12 weights on each wheel - Oh and the trick was to use TWO wheels instead of just one  ;)

That sounds interesting Jubjub...

But isn't the "Dumbbell" design using TWO wheels? On the same axle?

@Jubjub,

Didn't know one can simulate natural motion in 3DMax. Thought you have to indicate the trajectory ahead of time and thus you force the program to calculate the motion along that particular trajectory which may be a completely unrealistic trajectory physically. Can you please post the 3DMax file here? I'm curious to see how you've done the running along a natural path..

It seems I threw the stick in the hen house with my requests to Groningen.

Just received about six emails from confused officials...

It seems the question now has been relayed to the correct department.

The plot thickens....

AZ

This whole governmental side of the story sounds very strange. Abeling writes:

Quote
We have permission to construct and exploit Weight Power Plants in The Netherlands.

How come, if such permission is indeed needed, the county of Groningen is the one to decide for the whole country of Netherlands?

Also, this

Quote
We can use the existing infrastructure.

doesn't make sense either because in countries such as the USA and, as far as I know, all European countries the utilities are obliged by law to buy the electric energy if someone produces such and decides to sell it to them.

It could very well be that the above statements are thrown in just to make the everything sound official and approved which for the gullible would mean that perpetuum mobile is a done deal, that it's real. Hope that's not the intention of these statements and what is really meant just isn't expressed well.

Snapshot.

Things i cannot place marked in red.

This could very well be a construction which is supposed to go between the plates.

Look at the bottom one, rotate left, what do we see? Looks like a stopper barrier to me.

I know...this is an old post from AquariuZ – but I think I have found something new and interesting:

What you call a "barrier", that I believe is actually a "Shooting" mechanism.

The whole guide tuns like a pendulum when a weight fall at 04:00, and push the "Shooter" to the left.
When the weight reach "weightlesness" around 09:00, the pendulum guide falls back....and the "Shooter" fire.

How does that look...?

@X00013,

I got it. To get rid of the background sheet just un-check in View the buttons for Background and Working (not intuitive). Then proceed in SolidEdge as if mm are meter and orient everything w/ respect to the zero of the coordinate system. Thus, when you import the created dxf in wm2d the new sketch will be positioned properly w/ respect to the earlier sketch (which is also drawn with respect to the zero of the coordinate system). This whole thing makes a lot easier the drawing and the import of the various details into wm2d. Now will have to figure out what the for of the track should be.

Due to the site being down for maintenance yesterday I was unable to upload anything until today.

Here's the link for the video of my rough version -> http://www.youtube.com/watch?v=3skVetNsbZY

As for the Max-file you'll have to wait until I get home from work (Yes, I'm at work right now...)

Ruggero, YES COULD BE

It is so sad I do not have a decent 3D modeling program nor the CPU cycles to correctly model...

Frustrating...

Jubjub, what software is this? And is there a free or demo version I can abuse? I wish to understand if this has accurate gravity modeling in it.

Also:in the patent or like dustys design the grooves are offset and do NOT point to the center axle... Other than that: full marks.

@Jubjub,

The way I depict motion in 3Dmax is by indicating a trajectory along which the body should travel and then letting the program calculate how the body should look like at each point of that trajectory. It can be any trajectory, even a physically un-realistic one such as, say, water running uphill. It’s like drawing a cartoon. I know of no way in 3DMax to have a, say, stone fall to the ground under its own weight, if the trajectory of this fall isn’t assigned ahead of time. In other words, as far s I know, there’s no way to do what wm2d does – solve the equations of motion for a body at given initial conditions and represent graphically these solutions. If what you’ve done in 3Dmax isn’t doing that then it’s just an illustration of something desired but not necessarily physically consistent such as the models with the attached motor @Cherryman was showing, or in 3D the models @tao was showing of Torbay device. I hope I’m wrong and 3Dmax can do also real life simulations showing the natural path of motion.

I'm using 3ds max - A 30-day trial can be downloaded from http://usa.autodesk.com/adsk/servlet/index?id=5659302&siteID=123112

I have uploaded my max-file to http://rapidshare.com/files/227559769/GravEng08_1.max (It's for Max 2009 and later)

@Omnibus,

You are both right and wrong about the whole trajectory thing.
If you model a a stone with a given weight, an unyielding groundplane, add some gravity and use max's Reactor to simulate the whole thing, the stone will drop to the ground (and bounce around depending of the amount of elasticity, friction and general surface shape).
However if you want to create a scene with a football penetrating a window you would set the animation up as you stated.
Something like animating the ball over 10 frames, and then let the physics system take over.

I've been using Max for more than 10 years, so I believe I've got the hang of it over the years. (My job is creating commercials, and visual effects for video and movies - how cool is that?  :D)

Hi Jubjub,

I too have been using MAX for several years for design visualization. Despite this, I've never been able to get reactor to work right. It always just "explodes" the objects in the system all over the place. Do you have any idea how to fix this?

@Jubjub,

So, what you're showing us is a natural behavior of the device, just like the the natural fall of the stone let go from some height w/ respect to ground? It isn't motion along a predetermined trajectory, correct? If that's the case then it's most interesting to discuss this further and see whether or not there might be hidden problems. Recall how many times we had working models in wm2d only to find out there might be something problematic with them.

If you create a reactor object with no trajectory (via. moving it from one position to another after moving the frame time) it will simply fall, endlessly if there's no ground plane...
