High temp superconducting materials (most of them) still require liquid nitrogen temps to operate properly. How do the keep these lines at these temps over long distances?

They can't run them long distances, period. The lines shown are enclosed in pipes full of liquid nitrogen, run underground, and for only 2,000 feet from point to point.

We're a long, long way from widespread superconductor usage.

Too bad the Roswell flying saucer wasn't wired with room temp superconductor wiring, so we could have been using the stuff for the last 50 years.

It did.

That is why we're trying to get to the next stable transuranic island. Dekacuprum and eckapalladium are essential ingredients, processed with a thetatransplatinum catalyst.

these things take time.
