However, if the battery were discharged below
its starting capacity, by any peradventure, the car could be started
by the old-fashioned cranking method.

Using an automobile lighting system for house lighting implies that
the car be stored in a garage near the house or barn; as this battery
is too low in voltage to permit transmitting the current any distance.
One hundred feet, with liberal sized transmission wires is probably
the limit.

That such a system is feasible is amply proved by an occurrence
recently reported in the daily papers. A doctor summoned to a remote
farm house found that an immediate operation was necessary to save the
patient's life. There was no light available, except a small kerosene
lamp which was worse than nothing. The surgeon took a headlight off
his car, strung a pair of wires through a window, and instantly had at
his command a light of the necessary intensity.

Another manner in which an automobile engine may be used for house
lighting is to let it serve as the charging power of a separate
storage battery. The engine can be belted to the generator, in such a
case, by means of the fly wheel. Or a form of friction drive can be
devised, by means of which the rear wheels (jacked up off the floor)
may supply the necessary motive power. In such a case it would be
necessary to make allowance for the differential in the rear axle, so
that the power developed by the engine would be delivered to the
friction drive.
