You asked for a test and asked a question, the one where my max lift was 1204g was done with the system assembled and using the feed tube and displacement piston for the input, the weights I gave for the  risers were with them out of the system.

Ah, Ok, I reread your post after a couple cups of coffee and now I get it, thanks.  I understood you used the full setup for the big lift, I just needed to know the input, and you gave me that, I think, if I can remember the weight that pushed the piston down.

And earlier you said something about a full riser sinking... does that affect your earlier sink weight measurements?

@see3d: your attitude is admirable. The essence of the scientific method is the search for one's own errors, the attempt to refute one's own hypotheses, the unflinching examination of data no matter where it leads, even over the cliff of career destruction ( google HeLa Adam Curtis Documentary).
Keep it up and thank you for your hard work.... I know how difficult numerical modelling of physical systems can be.

Yes, especially systems I didn't understand before I started.

Thanks for the kind words.

I have a personal motto:  Never give up!  How can someone be called a failure if he is still trying to succeed.  However, to give up is to admit failure.  I am allowed to refine my goals as I learn more though... :-)

Thanks for the video on the fountain.  Say, where did you find that human to do the grippy stuff for you on assembling it... LOL

It may even be possible just to float some plastic spheres of the right diameter on the water surface "ring" around the annular walls

Why not use some cheapie nylon rollers? A pair arranged vertically, repeated in a triangular or quad fashion (if viewed from top) should work, low friction, low weight.


Question: what is the desired mass target for actual risers themselves...weight wise...lighter is better, middling, or there some value they need to be optimally?


That is, should they be lighter than the water, or heavier, or neutrally buoyant...


Stated again, if sunk in the water sideways like a filled cup, assuming it is deep enough, they would a) float bigtime, b) float just under the surface, or c) sink fairly quickly d) sink like a filled Titanic.
