with a double helix, I have a double entry, so double Fl-Fr, why you think you don't have Fl-Fr ?

With this single or double helix you can mutiply the numbers of turns without increasing difference of force from right side to left side... the area covered by the helix in the lateral wall is the same with few or many turns... consequentially you can do same work with less liquid... this aren't my word but yours! and with that helix i think it is possible to achieve overunity

Not from gravity but from temperature. Take this circular helix. The helix is closed to itself, no end. The helix has gas inside at pressure P. Put in a container with pressure at 0, this give energy e1. Increase diameter of the helix without change the volume, the pitch decrease and this give energy e2. Move out helix, this need energy e1. The sum is e2.

Second image:  increase d, sure c must change too.

Why from temperature? Energy come from pression....if in the container the helix will change shape due to torque...

imagine a helix with 2 ends (not close to itself), if diameter increase the energy needed come from these 2 ends, but without 2 ends, if diameter 'd' increase, I don't lost energy from these ends, sure if the number of turn is the same this would say the diameter 'c' decrease in the same time but it's not a problem I think

Talkin' about your first idea.. I'm not sure volume increase using an helix insted a common linear hose....

no the first idea don't work, the volume is the integral of the section along the lenght

for the second idea with pressure, I think it's possible to change the number of turn and increase diameter in the same time without change the volume.

In this case,witch value has the pression inside the container,considering the empty flexyble hose inside. F/1 or F/2?

the section increased in the same time, pressure is higher due to the larger volume but the section (surface) is larger in the same proportion. If you want to have the small section you need to basculate (slope) the container in the same time you move up or down.

had you try to understand second idea with pressure ? Entry a circular helix with gas inside, the lenght of helix is N*sqrt(r²+(p/2pi)²) with N the number of turn, r the radius and p the pitch. When the helix is inside container where there is 0 pressure, I transform the pitch to radius (volume = constant).

If there is a torque that change the shape of the helix,it would be better put she in a container ful of water,and varing the pressure by a weight on the surface...maybe...

if the diameter increase, this give energy from a torque (think about a helix with 2 ends, you will see that is ends that lost energy), sure I can't increase diameter from nothing all along the helix, but like helix has pitch length, I can reduce pitch so I can increase diameter. I don't think pitch lost energy because it's linear not circular. This need to be compute for verify.

Another idea with 2 spirals. One spiral turn clockwise, another turn anticlockwise. The container move down with a velocity relative of the angular velocity of spirals. The container move down with the additional volume from the black cable. Black cable is empty and has no weight in theory, in practice imagine it with very thin walls, and it is full of of air inside. Black cable give a up force, but this force is not give to the container, spirals control this force. Container move down with additional weight from the volume of black cable. Spirals turn only, they don't move down. Cable is rool up around red cylinder like a helix.

Second image: the cable slide only, cones don't turn like that no torque from up force inside water.

Watch this, quite an interesting and practical idea to convert gravity into light.

Best,
