"Look here," interrupted DuChane. "Isn't it possible that the coating on the sphere somehow acted as a storage reservoir into which your current poured until it built up this—this terrific potential you've mentioned? I mean—well, perhaps this storing up of power multiplied the current generated by your dynamos, until they overcame the objection Lamberton pointed out—that of obtaining sufficient power to produce the atomic stress."

"Nonsense!" Eli retorted reddening. "That imbecile has not the brains to grasp even my basic theory. There is no connection between my conversion coils and the mud coating!"
