The main issue is that this only works on things that are tiny enough that a micro-layer of surface air can substantially affect their buoyancy. It's a cool trick, and I'm sure it has uses, but it's not going to do a thing for planes and ships. It'd be like trying to float a Buick by tying a party balloon to it.
