He believed he used coke and
took one pound per horse power. He should not like to cross the Channel
in the electric launch, if there was a heavy sea on, for shaking
certainly did not increase the efficiency of the accumulators, but a
fair amount of motion they could stand, and they had run on the Thames,
by the side of heavy tug boats causing a considerable amount of swell,
without any mishap. Of course each box was provided with a lid, and the
plates were so closely packed that a fair amount of shaking would not
affect them; the only danger was the spilling of the acid. Mr. Crohne
had remarked that a torpedo boat of that size would have 100 indicated
horse power, but then the whole boat would be filled with machinery.
What might be done with electricity they had, as yet, no idea of. At
present, they could only get 33,000 foot pounds from 1 lb. of lead and
acid, though, theoretically, they ought to get 360,000 foot pounds. Iron
in its oxidation would manifest theoretically 1,900,000 foot pounds
per lb.
