Wheel vs. lever...

The latest test takes the weight from noon to 9 pm but when it goes past 4.30-5 the weight goes outside the circle and would take work to lift it back into a balanced position. Now the hard part is to get the switching to work with the power that is created from the rotation/leaning. Indeed it is a very clever idea to avoid the losses in the reset.

Using crude measurements


1. set   One nut moved horizontally 1.5 in. with less than 1.5 units of work
2. lifts an equal nut 5.5 in  366% OU
3. reset 1.5 units of work

giving a minimum of 183% OU.

So manually one marble would lift another marble 5.5 units and 1.5 units of that work out could reset the machine to repeat the process.

But I would guess half a marble would move the marble  horizontally increasing the OU to over 600%.

So picture this. A marble machine where you move the marble to do the set and it lifts another marble 5.5 inches which can then be partially used to reset and move the arm back so its balanced. You then do the reset and then the set and all you have done is roll 2 marbles  horizontally to make at least 3.5 units of free work.

As my neighbor says "There you have it".

It was a friend of mine who made this sketch, which has since disappeared and was plagiarized by this site. there are a lot of TDCs on this planet!!. It's a wrong direction, the imbalance of any kind can never reset, and that's logical, forget Newton's laws, just experiment, it's never going to work in this direction, but there are others.

Thanks for sharing this method. It has lots of merritt but what I have found is that when weight is shifted  as in this case just past noon that half of the wheel becomes bottom heavy and that has to be corrected before it gets to the bottom. And usually one thinks that adding more weights will fix it but I have found that often it reduces the work out because now there is more mass to move.

So my current effort is to add something to undo the bottom heavy problem before its too late in the rotation. But without some clever geometry it will counter affect the rotation.

Currently I do not have a wheel but a "seesaw/pivot/rotation" that works best in reverse of the drawings.

But the great point in this design is that it has a smaller "reset" loss than other designs I have seen and worked with. When the shifted weight starts the wheel to turn the "reset loss" is not near zero unless the weight is at the bottom and with a wheel in motion that would be tough to time correctly.

I am only using 2 weights/arms
