Sjack Abeling Gravity Wheel and the Worlds first Weight Power Plant

Looks like there is as much resistance to different ideas here as there is in the scientific community. Those who have the resources don't want to explore concepts that differ from their own.

I'd really like to see what a skilled wm2d user like Hans or Mondrasek could do with these proposals.

Oh well ...

It isn't that Oc. Put quite brutally, the designs shown in this thread to date have simply no chance of working. Why make a simulation of something that obviously cannot work.

You must, in evaluating a design, look at what energy is available and how much energy is required to induce rotation. This is sometimes hard to see. In your design it is so obvious that it cannot work that it makes a good case to illustrate what I mean.

I have annotated your design below, it should be self explanatory.

If gravity was the only mechanism to be considered, you would be correct ... and you may very well be correct anyway. When the ball exits the wheel at the bottom, its gravitational potential is pretty much spent. But it still has momentum, momentum that is dependent on the rotational speed of the wheel.

I have already stated this is not a self-starter. If it can work, it will also depend on having enough momentum to climb the chute to a point above the axle and still be moving faster than the spoke so when it is recaptured by the wheel, near the hub, the impact contributes a bit of positive energy in the direction of rotation. How fast does the wheel need to spin for the balls to gain enough momentum? Can the wheel rotation speed be maintained? Is there an optimum angle for the impact? Those are questions I would think the simulation could answer.

AquariuZ answered questions about my initial design, which used gravity to try and rejoin the wheel. Well gravity wasn't fast enough to keep up. So I have modified the concept to use residual momentum to rejoin the wheel at a point near the hub, where the rotational speed is slower. At some rotational speed, the balls should be able to rejoin and transfer some energy back to the wheel.

Gravity provides some rotational energy on the ride down. The impact as the ball rejoins the wheel provides additional energy. Is the sum of the energy inputs enough to keep the wheel rotating? That's my question. And I don't have the math background to calculate the answers.

If I had the software, I'd sure try. But I'm afraid I can't justify $3,000.00 just to satisfy my curiosity. I was hoping you might be curious enough to give it a whirl.

Here is a simulation similar to Omnibus' "Hockey Stick". It is easy to see why that won't work either.

Omnibus,

I know one meaning of 'closed' and sure, these drawings are closed path...but I think the wm2d cannot deal with open path (like a straight line or maybe two layered drawings.(?))

I made one more file as a 'compound' path (like clipping holes in paper) instead of layer.

If that doesn't work you might open the file in Text/Notebook (it's ascii) to see the element's measurement description (beware: it's a damn long textfile)

Hans: You are a skilled user of wm2d...Are you able to import this file into wm2d?

good luck

Hans,

The rigid joints in your model are again on Optimized. Why?
