The upward flow of the bubbles will create a vacuum in the tube that will have a pulling resistance on the floats as well as they will have a resistance on the curve when they flow against the floats.

Look closer at the tube, it is not solid there is still a gap for the devices to ride through. Water is dispersed from the tube by the bubbles. This makes it less buoyant so the weighted floats can go down easy so the lifting side has full buoyancy for the lift to create the rotation. The only true problem is can I get enough bubbles to make the process work with in the closed loop of the design.

@ ABhammer,

I mean what Farid suggest. But my idea is a little bit modificated. I didn't thought to press air in the vessel but softballs (balls filled up with air).
If they are risen in the vessel they could fall down outside the vessel. But the key is how is it possible to get them in the vessel. The idea with a compressor or an air pump could be efficient enough.

AB Hammer, any upward or downward flow will create a current in the direction of the flow and the current will act like a suction. Some examples would be the effects of a sinking ship and the effects of the rising of the ship after it has sunk.

Greetings Nightlife

Since you have been looking at sinking ships, you need to look at how bubbles can sink ships as well.
