 Yes I understand all you have said. But I don't see the travel. But I will await your build.

AB Hammer your right about the travel....I did some basic math to this.... the counter weight(red pulleys) need a lot weight

I rounded in Yortuk's favor but at the end you need over 6.5 times of swinging  counter weight to center weight , just to balance this
IMO this will not work and wastes peoples time.

You're a funny guy. What part of "THIS IS NOT TO SCALE" do you not understand?

Whatever weight it takes to move the main weight is what the counterweights must weigh. Whatever diameter the counterweight wheels must be to turn the rollers to move the main weight across the main wheel is the diameter they must be.

This picture is to give people the general idea of how this system works. I'm glad you have an opinion on it. Since it is your opinion alone, then it is a waste of YOUR time. There are many people who DON'T think this is a waste of time and are now making their own sims and models because they see that this will work.

I hope you find something better on which to spend your time.

actually your right this is my opinion....I should not force/tell other people this is a waste time

also I did not prove this wheel will not work. The final math would involve the center weight force minus the counter weights force as per positon on the wheel.  I threw in numbers to show how much of a relationship the force each wheel has to each other and the center weight.

Your right there is probably a perfect counter weight/ counter weight diameter and position.  When this is acheived you will have a balanced wheel that will turn as far as the friction will allow it.

I guess I'm making this a little personal....but when you see "breakthrough" ...I was a little let down

As I mentioned in a previous reply, I did get a similar design to work in Phun(although only temporarily due to Phun's limitations).

The holy grail of gravity wheel design is getting the weight back to the top to restart the process. This seemed to work in my simulation but this is such a simple design, it wouldn't take a lot of effort to throw one together to validate it.

I'd be willing to take a crack at it once my pendulum project is complete.

Actually you did Lilhawk,

You don't need more precise maths to show the unworkability of the design. Even on rough calculations the discrepancies are far too large to be made up for by a more precise approach.

Charlie (noonespecial) asked me to post this from the other thread:

another solution is to let the whole set up flip on a horizontal axis.

yeah - maybe even start the rotation when the weight is lifted just over halfway up...?

Tomorrow I'll post a video of a simulation showing this working as described.

I apologize but because of personal reasons it looks I won't be able to do the video until tomorrow.

Yortuk,

I tired to respond to your personal message but it crashes each time I do.
You can send me an email at purelyprimitives@charter.net.

Thanks,
Charlie
