So far, primary batteries have been applied only to the operation of
the smallest stationary motors. Their application in the near future
to traction may, I think, be entirely disregarded. Were it not a
purely technical matter, it might be easily demonstrated, with our
knowledge of electro-chemistry, that such an arrangement as an
electric primary battery driving a car is an impossibility.
In view of the claims of certain inventors, I regret to be obliged to
make so absolute a statement; but the results so far have produced
nothing of value.
