Crucibles of Creativity: The Labs (continued)
Having recovered quickly from the defeat and failure
of a decade of striving in iron mining, Edison decided in 1900 to make a
better battery.
Huge and efficient generators of electricity were
already in use. Called dynamos, they were progeny of the first 90
percent efficient generator developed by Edisonthe "long-waisted
Mary Ann." A necessary auxiliary to these dynamos was a means of storing
power for a long period. The storage battery was in common use, but it
was of lead-acid construction, heavy, and destroyed itself in rather
short order. Edison, the master innovator in the power field, saw the
need for a battery which would last longer and be lighter. He believed
that electric motors were superior to gasoline engines for use by the
infant auto industry and that a better battery would make electric cars
truly competitive.
By 1901 the West Orange lab was gearing up for the
new quest. He hired a staff of about 90 men under a chief chemist,
gathered a huge assortment of materials to be tested by the Edison
method, and began the search. For years they experimented intensively.
Always, it seemed that when they had developed one characteristic in a
battery which was desirable they found another which was not.
Edison obtained many patents during this period
before finally coming up with a nickel-iron-alkaline battery. It was a
great improvement over lead-acid types in several ways. It was slow to
decompose and it was light. It also was reversible; that is, upon
charging, the battery would reassume its internal physical structure. It
held a charge for an extremely long time without recharging, but it was
expensive and could not deliver enough power for its weight to make it
useful in all-electric autos. Nor could it provide the heavy initial
current needed to start a gasoline buggy.
Despite these problems, the nickel-iron-alkaline
battery was a magnificent example of the Edison quality and was used in
mining and railway devices. Some Edison batteries have been known to
last a generation. He could well be proud of his handiwork.
A bakery in Lincoln, Nebr., not only
used Edison storage batteries to power its trucks but advertised its
then novel way of baking bread, by electricity. While working on the
nickel-iron-alkaline storage battery in the early 1900's, Edison also
produced poured cement houses.

A foray into the world of building construction
consumed his interest for a while. He wanted to utilize the then idle
heavy machinery at Ogdensburg. He converted it to manufacture cement and
built a complex of factory buildings around the old lab entirely of
reinforced concrete. He tried to interest the public in prefabricated,
poured homes, remarkable structures which, when iron molds were removed,
contained stairways, rooms, halls, cellars, and conduitsall of
concrete. But the idea was too advanced for that day, and Edison gave it
up.
As he took up new experiments and invented various
devices, Edison would form manufacturing companies. He started almost
200 companies and corporations. Today power production utilities across
America bear his name in the fashion of Consolidated Edison of New York
City. McGraw-Edison Corporation is the direct descendant of Thomas A.
Edison Industries, Inc., and only in 1972 did the corporation vacate the
reinforced concrete production facilities around the red brick lab on
Main Street in West Orange. And, of course, General Electric traces its
lineage to him.
