Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

[hartiberlin]

I wanted to make you a file with just one wheel, and decided to take the one that I allready uploaded and just delete the barriers and dumbbells on the far side.
Just for kicks I started the simulation... - And it kept running...

Hi Jubjub,
great animation.

Please try to export your3D model as a projected 2D model of the slotted wheel
as a DXF file and post it please here.
Maybe we can this way try it with the WM2D Simulation software.

@Dusty,
great work man,
keep on going.
In your last video, please try to remove your bottom barrier,
as it might just have too much friction.
Please read the comment I made at youtube.

Many thanks.

Regards, Stefan.

Hope @Cherryman saw @Jubjub's sim. It uses exactly the 3D sim software he was looking for.

Okay, I'm back with another report.  I know this is getting positively ridiculous to have this many video's of this gravity wheel, but I just want to show the step by step progress on the ideas as they develop.

As an over view of this project, after the patents were posted I proceeded to build a 3D model of the basics that were given.  After building the machine I had something real for testing which led to making changes for the purpose of seeing what might be better.  If an idea was worse then I went back to what worked better.  So far I made one change to the lower track and just recently I made one change to the upper track.  On the wheels themselves I tried four different slot layouts.

Now I'll explain each video test, and keep in mind I'm looking for the most rise in the dumbell and also the rotation of the wheels. 

In this video I'm showing new hockey slots that are aiming straight towards the axle from both sides.

In this wheel I flipped the two wheels and cut a new hockey end to test the opposite slot angle as compared to the original slots.

Here I've added the curved slots.

This was real interesting, I'm showing a test I thought up, showing that the wheel going past the 360 degree point by having the dumbell fall and follow the track.

In this video I removed the dumbell and attached a five lb weight and just had it fall and rotate, not following the track, and it went 16 inches less than the previous video.
http://www.youtube.com/watch?v=-qjStWmfvnI&feature=channel_page       video 0767

In this video I'm showing just one dumbell fall and follow the track.  This hockey slot track was the original slots on the wheel.
http://www.youtube.com/watch?v=74G_kSf5cS4&feature=channel_page      video 0768

Then this last video is showing the new upper track layout, with super fast acceleration.
http://www.youtube.com/watch?v=_pmdExy6xsQ&feature=channel_page     video 0769

One thing I haven't showed is that I have used 2.5 lb, 5 lb and 10 lb weights for the dumbells.  More weight actually slowed down the rotation and too little weight didn't provide enough torque.  It looks like 5 lbs. is just right.

So now I'm just about finished with this first wheel.  I have one or two more tests with the track layout for optimization of bumbell rise.  Then it's time to build a bigger wheel.  It will be six feet in diameter and will have all eight dumbell weights installed.  A bigger wheel will make more room for all weights and give a longer hockey stick for extra leverage.  On the lift side of the wheel the distance from the slot to axle will remain the same as you see in the current wheel, but the outer torque distance will increase almost twice the distance.  I'm going to use the curve shape on the bigger wheel.

Thanks

Great work Dusty

The last one is a WINNER. It matches the abeling "D"...

Hopefully you can create the same accelerating curves to run a full test but this looks promising...

What a monumental effort you are putting into this, thanks for persisting...

@ruggero and everyone else who doesn’t have wm2d, here’s a vid of a simulation with @Rusty’s type of a motor: http://www.youtube.com/watch?v=vf37W1C4uzc&feature=channel_page. Conditions are the default ones in wm2d and are supposedly ideal in terms of lack of Air  Resistance being set to None. However, static and kinetic friction is set to 0.300 while elasticity is set to 0.500 for all elements which is far from ideal. No need to mention that these parameters, especially friction, are very important to be set correctly and not overestimated â€" any common machine will stall if friction is made too high. Also, the weight of the spheres is 0.1kg while the weight of the grooved wheel is 1kg. Here @mondrasek may raise the same objections as the ones he raised concerning an earlier video (http://www.youtube.com/watch?v=9-dT4MZCtYo) simulating @eisenficker2000's idea, namely that the Animation Step (0.050s) and the Integration Error (0.010m) are too crude. However, try to change the geometry of this same model and you’ll see that the self-sustaining motion ceases although the same elements participate and the same confusion in calculations @mondrasek mentioned in connection with the earlier vid should be in effect.

Probably it should be mentioned that the symmetric grooves in Abeling’s patent unlike what apparently are grooves of various shapes seen in the wooden rotor of the machine in the barn seen in Abeling’s video may indicate that the problem with the trajectory of the dumbbells in a working machine may be more involved that what we’re portraying it in our renditions. @Rusty may be exploring that possibility so the present sim is just one basic variant along the road to what the solution may turn out to be.
