The energy needed to push the balls though the seal is where it fails.

The balls put the chain in tension. Thus any submerged ball experiences a tension force downwards. This will match the bouyancy force upward, so the system will pretty much stay in equilibrium. No free energies I'm afraid.
They are all filled with lighter than air air? Great idea! How does the chain know that one half of the balls must be heavier to go round?
