When Daddy was 19,
electricity came to Indianola in the form of DC current; this marked
the beginning of the end for those long winter nights. The DC current
also worked just fine in replacing the kerosene street lamps. Daddy
remembers one night overhearing two ladies walking down the street and
remarking what a vast improvement the electric lights were.
This was the age
of intense competition between AC and DC type of electrical distribution.
Thomas Edison, championing DC distribution, used armature brushes to
devise a way of realizing DC from an electric motor generator. On the
other hand, Westinghouse was puruing his electrical transformers, which
could conveniently step up the voltage so as to save loss in transmission
lines. It was an epic technological struggle between Edison's DC power
and Westinghouse's AC. Westinghouse won, hands down; AC electricity
is now used almost exclusively everywhere in the world.
