Recover energy from gravity

[rc4]

the container must be like that for have angle constant
why turn ?

[Gabriele]

Nope

[Gabriele]

Can be?

P.S: Are you surethe fall of the container doesn't balance energetically the energy gained from volume rised from revolving?

[rc4]

the volume is always the same with last image (parallelogram)

[rc4]

If the helix is in a parallelogram, I compute the volume less forces Fr-Fl but the weight come from the full volume of helix inside water, but there is less surface due to the helix, so the weight is lower than in the first parameter. The total is 0, but if the first parameter is not exactly that, the sum is not 0. In my calculation, I don't compute f1 and f2 forces of the weight, I consider the full weight, but it is less, it's Weight - (f1 -f2)*surface, so the sum is not to 0.
