Hi AquariuZ ,

so you say, that this wheel does not work using centrifugal forces ?, cause
otherwise from 9 to 12 o´clock the weights would be pushed by the centrifugal forces
outwards to the rim and not going up your outer barrier in center...


No, no I do not say this. The torque is on the right, the momentum pushes the weight out and up, past the lower barrier, where it will have lost its kinetic energy and gets pulled up by the momentum where gravity starts pulling it down and thus it meets the upper barrier on the outside and moves up that one to finally land in its own socket again at 12:30

Quite simple really.

Model is not done yet, it promise it is worth the wait as it seems to work exactly as I think it does.

Just do not want to post half baked

Its getting better..

http://www.youtube.com/watch?v=_VbxHhE3_7I&feature=channel

Are you still running it via a motor or
is this already running itsself ?

Your KAD7 file under Version 8.x
has still inconsistences...
Just takes ages to render frame 1...
Can you please post your newer files please ?

Many thanks.

Here it is.

I Still use a motor, because of the testing. Curve, timing, catch&Hold..  I want it smoother and more natural.. 

well, it's fun!   8)

Here is the file:

Stefan, please hear me out.

With just the 4 arms in your video, no guides, if it spins fast enough, the balls will be stuck to the outer end due to centrifugal force, right.

Now add a trapdoor at the end of each arm, so if the trap door springs open, the ball will go flying out in the appropriate direction.

Now add an external curved ramp mechanism below the wheel, so that if the trapdoor opens above it, it will catch the ball and allow the ball's momenum to carry it back to the top.

You also need a trigger to unlatch the trapdoor near 6:00 so the ball will fly out at the correct time.

The trapdoor should stay open until that arm reaches the top, and should only close when a ball reenters the wheel at the top, then it should latch until it reaches bottom again.

The wheel will need to be spun up with all balls onboard until it reaches a speed where a ball escaping through the bottom of the wheel will have enough momentum to go up and around the ramp and reenter the wheel at the top. When the required speed is reached, the trapdoor latching/unlatching mechanism can be engaged.

The ramp length and wheel speed need to be synchronised so the ball reenters the same arm at the top it departed from at the bottom.

What you end up with, once it gets up to the required RPM, is a wheel with balls on one side and no balls on the other.

I'd be very interested in seeing a WM2D video of what I just described. If you don't understand what I said, just ask questions.

Thanx,
0c

If I only would know, how to design such a system with WM2D.

I am no WM2D Pro, so I only can do basic things.

Regards, Stefan.

Here is my little contribution :P

Edit: wow I just had a good thought, if the weights raised like they do in my drawing (below) but straight under the axle and above the axle, the weights have no weight on the wheel, their weight is applied to the axle instead, so long as they raise in a straight line...

Well, I've worked out the power cycle for the Sjack Abeling Gravity Wheel - and here it is.

http://i136.photobucket.com/albums/q171/frank260332/Sjackcycle.jpg

So it looks as though his gravity wheel really will work, though as he says, why someone didn't find this out a long time ago just by chance is a bit of a mystery.

Still, I suppose before knowledge of the Carnot cycle and the Leibniz calculus it would have been a bit of a mental stretch.

When I first recognised that the acceleration leg (d2x/dt2)and the rate of change of acceleration leg (the adiabatic leg - d3x/dt3) gave the potential for a power cycle I couldn't see where the other return legs were going to come from. But then I realised that cos everything is turning round the returning legs are the same as the outgoing legs. Tricky, eh!

But what on earth has this got to do with a Carnot cycle you may ask?

Well, think of the balls being thrown around as monster molecules and the structure enclosing them as the cylinder. The equivalent of the thermal potential change is the gravitational potential change and the adiabatic leg (the balls rising up) is where the motion energy is exchanged for gravitational energy.

If you don't understand what I'm on about (or even what I'm smoking  ;) ) I can't say I blame you.
And if you want to ask questions I'll do my best to answer them.

Oh, and one more think to note. The containing structure can be made as stiff as needs be so no significant power is lost to the structure.

@Cherryman,

I’m looking at your KAD9.wm2d file. You had set the Torque on Polygon 5 to 1 on x and y1, as far as I can see. I reset it to zero on both axes and re-renedered it. It appears that it can still make full turns. There’s a problem with the fourth steel ball, however, which existed even with the original torque which I don’t know how to fix. Mind you I’ve never worked with WM2D before.

Neither do I  ;D

Untill i have a satisfying setup, i do not much with the parameters of WM2D, but feel free to try of finetuning it will help.  Good luck.

When you change the material of the Body(5) - Polygon to Standard (whatever it means) from the initial Wood w/ steel balls weighing 100kg it makes 2 full rotations. During the third rotation there's a problem w/ the second to last ball. Nevertheless, if I'm doing it right, I think this is a notable achievement because it means that the wheel regains on its own what it has lost. It appears that it's now only a matter of fine tuning to have a working gravity wheel. Good job @Cherryman.

Indeed, that's the basic of the  K.A.D. System. Althoug it should work also without the flying Ball, i'm testing that right now.

I keep looking and reading, but after so many builds, I think I will wait on a video or other proof. Simply put, ramps have always been tried and so far no proof of one working. If Sjack has it patented, why not show the working wheel?

With Custom (don't know what it means) material works even better. Unfortunately, don't know how to make a video out of it. Hope Stefan can help in that and have it uploaded to youtube for others to see. Of course, the way it is now with a wheel weighing almost 3tons and 100kg steel balls one can hardly call it a laboratory scale experiment. Wonder if it can be scaled down. Nevertheless, excellent idea, @Cherryman. Hope it will lead to a working model. Good luck.

In fact, it seems I'm getting even better results with 0.1kg steel balls and 0.5kg wheel made of Custom material. I got 4 full turns but stopped the rendering because if I let it go further the program crashes for some reason and restarts the computer. Wish I knew how to make a video to show it to those who don't have WM2D.

I can do that, place upload the WM2D file then i will make you a video
