Hi Fletcher,

QuoteWork using only gravity force as the Prime Mover would have to have the ability to create on demand asymmetric forces that in turn produced torque.

You are right on the money. The mass can be used to asymmetrically self re-gauge itself especially in a geodesic fall. 3 axis lever.

Love the weights under the bench idea. Its one of those ideas that is so simple- but only after someone[you] has thought of it.

Thanks Neptune - necessity is the ... 
One feature I just realized I forgot - and will add tonight - Mond's bottom stop.
In a way I wish the blocks and 2x6 block were fastened to the top of the riser so I could limit its travel but I will add a stop under that bottom cross member. Then when I add the 16Lb weight I will see the "pre-charge" happen because of incoming water instead of being caused by adding the weight.

@Fletcher - I like your analysis method - comparing and calculating the outer riser height.
I'll try to get some numbers to plug in to that methodology.

Merging that comment by Fletcher and the hydraulic comparison reminder posted by Webby might be interesting.

Hi Seamus,

I will explain simply.

A heavy ball in a open cylinder.

A shaft stuck through the middle of the cylinder so that it is precessed. (first lever)

A heavy ball on an incline does what?

A heavy mass pushing a long lever arm does what? (2nd lever)

The torque from the lever arm with a beam at 90 degrees can make a virtual wedge lifting cylinder behind the heavy ball creating an incline with a wheel.

A beam at -90 degrees from the lever arm can create a counterbalance or fall in front (by dropping the cylinder) of the heavy mass. (3rd lever)

The ball has only one direction to go to re-gauge itself.

Hi Seamus,

I just started this project and this is my third printed cylinder. From my experiments it take very little energy to push the lever with the weight aiding. Like all gravity devices I need to build bigger more mass. So far my designs have been iterative I've been fixing issues as I come across them. I can tell you why this 3rd version will not work and working on a 4th larger version so I can get a 2" sphere with a lighter weight printed lever, but I am open to your thoughts on why it won't work and if so do you see a way to use this leveraged fall to aid a motor?

Hi Seamus,

I appreciate your input.

I don't understand what you mean by bottom though. The ball and lever portion are on the slope due the counterbalance and wedge behind it. The bottom where the rim of the precessed cylinder is contacting the ground is about a quarter of the way from lever arm between the counterbalance. In other words the lever and ball are always on a slope with the true bottom being slightly in front of the lever.

This is where I'm not understanding, logically you would think two objects on a slope would want to seek lowest point especially when a heavier object is behind it. The bottom is always being pushed ahead on the rim of the cylinder ahead of the lever and weight.
