Knitel's InfinityPump

[reada]

To be honest it's not that difficult to demonstrate. The biggest hurdle will be friction due to the cylinder walls, but this can be minimized with the right solution.

what is if one would reduce friction to a minimum by plastic bags - one on the upper half of the wheight the other plastic bag containing the lower half - no tight cylinder - inflateable volumes, depends on the material of the bag, but weight could be reduced
and one should use springs to pull the empty bag back up, while emptying the upper one

our maybe its just a stupid idea
i didnt do the math - just brainstorming

Excellent observation/animation

Will save lots of time

Raises a point that appears could be solvable ?

I think it's worth a try after a few refinements. The problem would be creating a seal around the piston, that will allow easy movement in both directions.

I like how you animated the displacement. Out of these designs I think the one I drew has a better chance, if at all. Would you please animate mine?

If you are learning about wheel and self movement every build is worth something for there is always a lesson.

Here's an improved animation I did that should fill the holes  . Cooperation leads to success. Btw I don't think that indention is needed at the bottom.
