[BC] Happy birthday and thanks for the electricity Nikola

[Jerry Mathis]

Well, I'm not an expert either, but as I understand it, the advantage with
DC over long distances is the lack of inductive reactance in the wires, and
mutual coupling to the other conductors, which DOES introduce significant
power loss. Also, capacitance of the insulators is irrelevant.

Other issues I can think of include smaller insulators (no peak voltage to
deal with), and, at the receiving end, easier interface to a different power
grid with respect to not only frequency, but phase.
