    c'mon now , surely you can figure out why cross country transmission lines are not surrounded with liquid nitrogen.

    Most of that was related to telegraphs and self resonant lines/circuits. You didn't know that we don't use self resonant circuits to transmit AC power?

    Also with data transmission, we no longer rely on an impulse to excite a resonant line. We use a thing called modulation. Maybe you've even heard of some of these modulation techniques, like AM FM PSK FSK PWM PCM etc.

    And as to the principles of using increased wire size and reduced temperature to reduce circuit resistance, it was nothing new then and is nothing new now.
