anything about batteries, Mr. Siegel?” “A little. I’m not an expert on ’em, or anything like that. I’m an electrician. But I know a little bit about ’em.” Sorensen nodded. “Then you should know, Mr. Siegel, that battery-making is an art, not a science. You don’t just stick a couple of electrodes into a solution of electrolyte and consider that 122 your work is done. With the same two metals and the same electrolyte, you could make batteries that would run the gamut from terrible to excellent. Some of ’em, maybe, wouldn’t hold a charge more than an hour, while others would have a shelf-life, fully charged, of as much as a year. Batteries don’t work according to theory. If they did, potassium chlorate would be a better depolarizer than manganese dioxide, instead of the other way around. What you get out of a voltaic cell depends on the composition and strength of the electrolyte, the kind of depolarizer used, the shape of the electrodes, the kind of surface they have, their arrangement and spacing, and a hundred other little things.” 122 “I’ve heard that,” Siegel said. Thorn smoked in silence. He had heard Sorensen’s arguments before. Sorensen didn’t mind discussing his battery in the abstract, but he was awfully close-mouthed when it came to talking about it in concrete terms. He would talk about batteries-in-general, but not about this-battery-in-particular. Not that Thorn blamed him in the least. Sorensen was absolutely correct in his statements about the state of the art of making voltaic cells. If Sorensen had something new—and Thorn was almost totally convinced that he did—then he was playing it smart by not trying to patent it. 123 123 “Now then,” Sorensen went on, “let’s suppose that my battery is made up of lead and lead dioxide plates in a sulfuric acid solution, except that I’ve added a couple of trifling things and made a few small changes in the physical structure of the plates. I’m not saying that’s what the battery is, mind you; I’m saying ‘suppose’.” “O.K., suppose,” said Siegel. “Couldn’t you patent it?” “What’s to patent? The Pb-PbO2-H2SO4 cell is about half as old as the United States Patent Office itself. Can’t patent that. Copper oxide, maybe, as a depolarizer? Old
