Under water gravity wheel

[Low-Q]

Hi,

I've made a drawing of a gravity wheel idea. I like the idea, but I cannot imagine 100% how it should work, or not work.

There is two weights, one on each see saw. These are pivoted with the green dots.
In that position there is an expanded air volume at the left side, and no air volume on the right side. The configuration of the weights and the pivots makes sure that it happens. With this configuration there will be more buoyancy on the left side than the right side.

The arrangement can be copied in numbers in order to even possible uneven run.

What do you think?

Here is an example with more of those arrangements.

It is an intriguing concept well worth a deeper look. My initial objection was it needs to get over the 12 oclock position to continue, which I doubted it would, but maybe it will.

some points.
the water pressure is higher at the bottom. so pushing the air down will take more effort than appears in the diagram.
at the very apex (12 oclock) there is no energy available to push the air down.
at 12:01 the energy available is very small, will it be enough?

Redraw your diagram at 12 oclock and see if it still looks feasible.

At 12 o'clock the bottom cylinder will be "inflated" and the top will not. The main concept is to have the majority of air volume on the left side. If it is, there will be unbalance in the buoyancy effect which will force the wheel to rotate. However, the weights have to change positions all the time while following the rotation, so they could counter balance the wheel. I have started to make some simulations in Phun. I have not yet succeed to make an air-tight cylinder. I will figure something out.
