Buoyancy/gravity wheel - another approach?

Funny picture

Well, cause the movement happens in liquid, if it works, it will be a low rpm system.
We must count the energy needed to pump the air down and the work it can do

Many "what ifs" here, but what if the tube around the wheel is pumped up and have an even shape - except the tube is compressed at the botton due to the higher water pressure. If the tube is pumped up, and the rollers are preventing the air from evenly spread on both sides, shouldn't the tension in the tube surface at the top be greater than in the bottom? This will in that case force the upper roller to move away from the tube. The lower roller is helped by the water pressure to compress the tube and release some of the tension down there, so the roller at the bottom is forced clockwise with less force.

Then if both rollers are fixed, the wheel is forced to turn. As no water is pushed up or nown - generally no mass is moved anywhere - the only force left is the difference betwen the tension in the blown up tube between the top and the bottom.

In the top you will then have a continously repelling system that is greater than the one in the bottom. The bigger the wheel is, the greater this difference will be. The wheel is then turning clockwise.

In an opposite case, the tube can be filled with liquid and let the whole wheel work in air, so there is more pressure at the lower roller than the upper - and the wheel will turn counter clockwise.

as bad drawing as the last one LOL , but I think you get the idea.

What do you think?

Well, i think the buoyancy force will affect the whole setup not only the tube and so,  no rotating force will appear. Thats why my idea has "near independent" air balloons.

Take a look at this idea for a bouyancy machine.


All you have do to is.
1. push the object down into the tub
2. switch the valves.

surely the work in should be less than the work out.

and all the lift is free.

it works because the water is locked into the tube similar to the locks
in canals that lift ships rather than dropping down the tube and water
is not liftted except for the little bit in the tub.
1. with valves closed push down into tub of water and position under the tube.
2. open bottom valve with upper valve closed.
3. when above the bottom valve and at the top valve close it and open top valve.
and then it pops up to the top.

then you have its weight that can do work.

Looks nice!
Now you need automatic valves that is activated by the buoyant material. Only one problem; How do the buoyant material jump out of the upper reservoir and down in the lower reservoir so it can repeat the cycle?
