I'll do that as soon as you post the cost to run 500 miles of superconducting lines to carry megawatt power.

Temperature in superconductors has nothing to do with voltage I have no claim to be an expert in superconductors, but I would assume that they still must have some finite resistance. If so the power dissapated in the wire generates heat. Finally- power is a function of voltage. I do know that usually superconductors are thought of as being limited by some current density above which they lose superconducting ability, but then power is a function of current too- isn't it. One could jump to the conclusion that the problem above a certain current density is localized heating- in that I'm just guessing. Do you know? In the big picture Ah is right- technology is nowhere close to economically sending power through superconducting wires. Thats probably many lifetimes away, and if someone said it's not then likely he's an idiot. Eric
