The linked article does not go into many details about what they are measuring. So I have to wonder: could this property be used to make thinner wires for conducting electricity in bulk (e.g.: hosing wires, or transmission lines) by stacking lots of very thin layers into a cable. I imagine there would be a good amount of development work to make manufacturing such a layered cable, so it would not be right around the corner. But is there any physical barrier to such a development?
