Would this system work, if the air-water isolation problem (water leakage into the air tank) is solved?

If it would work, where does the input energy comes from? We obtain electrical energy as output, but where does the input energy comes from?

No it would not work, see the "float belt" design;

The Buoyancy Machine is a classic perpetual motion machine. It's been failing to work for centuries: http://www.lhup.edu/~dsimanek/museum/themes/buoyant.htm

The buoyancy from all the balls on right hand side is not large enough to push the lowest ball on the left hand side into the water in the deep, high-pressure, region. So the belt will stop.
