Too nice to be true

Oil,water and air. We move the air inside the can,we loose the buyancy of the oil,we gain from removing the air.

Nobody is answering you because NOBODY can figure out what you are talking about.

It would help IMMENSELY if you LABEL which part is the Water, which the Air, which the Oil.
Also please Label Step 1, Step 2, Step 3, etc., as it CYCLES through the procedure.

So far NOBODY can figure out what you are getting at.

Ah come on Fatbird don't you know air is yellow, water is blue and oil is turquoise?   LOL ....   Well I agree it's hard to understand what he's showing here but I think I may be right on the colors.   But I'm not clear on what the benefit of this system will be.  If you are using air and/or hydraulics to move a cylinder up and down to gain energy I don't know if you can expect a gain but on the other hand since you are controlling a potentially heavy object by using counter forces of buoyancy and gravity then maybe there is something to the idea.
