[Milsurplus] DC vs AC for power distribution

[J. Forster]

Well, it depends on who is telling the story.

Tesla was a 'mad' inventor. Not a real engineer. His real fucus was on
radiated power. In recent years he has become something of a cult hero.

The real brains behind AC was Charles Proteus Steinmetz, who worked for
Westinghouse and did the fundamental engineering.
