Their claim is that directionality of power transfer is the reason directionality of wires makes the difference..Hence, the verbage about the power company selling you power..
But the link you post has not a thing approaching a credible justification for directionality. Nada..
Power transfer is simply...current times voltage.. if it is a positive number, the transfer is in one direction..if the product is negative, it is in the oppisite direction..
However, the wires see the current that is being moved, and the incredibly small voltage gradient along it's length, which is simple IR drop.
Each wire does not really see the gradient of voltage that it's partner has...the dielectric does, of course...but not the wire..
So, other than the actual dissipation within the wire (which is very easily measured....the explanation you have linked to does not provide any information...it only appears to be a layman's attempt at bringing in some really good sounding technical verbage to the party..
If they really want to bring grain elongation directionality into the game, they really should learn about the drawing process and it's limitations..like, the lubrication used as the wire is pulled through the die..I've been bitten by that one big time..
