No doubt if it was cheap and easy we would have it.
How much more air would be required to achieve lift off at a given depth? Is it as simple as another bottle or same bottle design under more pressure? As life vest rises to the surface and water pressure reduces, a relief valve could release air pressure?
Too hard? Too expensive?
