"Half armed, at least. Ah, for something to soak up electrons. I'm now wondering if this electron gun is such a good idea."
"Might squirt some protons out the other direction," offered Hadley.
"That would leave us without either," said Don. "We'd be like the man who tossed baseballs off of one side and himself off the other—Hey! Of course we have some to spare. We can cram electrons out of the business end, thus stripping the planetary rings from the atoms in our cathode. From the far side we'll shoot the canal rays, which in effect will be squirting protons, or the nuclei. Since the planetaries have left for the front, it shouldn't be hard to take the protons away, leaving nothing. At our present voltages, we might be able to do it." Channing began to figure again, and he came up with another set of anodes to be placed beyond the cathode. "We'll ventilate the cathode and hang these negative electrodes on the far side. They will attract the protons, impelled also by the positive charge on the front end. We'll maintain a balance that way, effectively throwing away the whole atomic structure of the cathode. The latter will fade, just as the cathodes do in the driving tubes, only we'll be using electronic power instead of sub-electronic. Y'know, Hadley, some day someone is going to find a way to detect the—we'll call it radiation for want of anything better—of the driver. And then there will open an entirely new field of energy. I don't think that anybody has done more about the so-called sub-electronic field than to make a nice, efficient driving device out of it.
"Well, let's get our canal-ray electrodes in place. We've got about two hours before they realize that we aren't going to come in at Mojave. Then another two hours worth of wild messages between the Relay Station and Mojave. Then we can expect someone to be on the lookout. I hope to be there when they begin to look for us. At our present velocity, we'll be flirting with the Asteroid Belt in less than nothing flat. That isn't too bad—normally—but we're running without any meteor detector and autopilot coupler. We couldn't duck anything from a robin's egg on up."
"We'll get your anodes set," said Hadley.
Walt Franks grinned at Arden Channing. "That'll burn him," he assured her.
"It's been on the way for about twenty minutes," laughed Arden. "I timed it to arrive at Terra at the same time the Solar Queen does. They'll send out a special messenger with it, just as Don is getting aboard his little scooter. It'll be the last word, for we're not following him from Terra to here."
"You know what you've started?" asked Franks.
"Nothing more than a little feud between husband and self."
