"... And that's the way it lines up, Ole. The CAA won't clear his ship for take-off, and the Space Force won't either. And if he tries it without the O.K. of both of them, he'll be right back in Alcatraz."

"He hasn't violated his parole yet, though?" Winstein's voice came distantly.

"No." Elshawe cursed the fact that he couldn't get a vision connection with New York. "But, the way he's acting, he's likely to. He's furious."

"Why wouldn't he let the Space Force officers look over his ship?" Winstein asked. "I still don't see how that would have hurt him if he's really got something."

"It's on the recording I sent you," Elshawe said.

"I haven't played it yet," Winstein said. "Brief me."

"He wouldn't let the Space Force men look at his engine or whatever it is because he doesn't trust them," Elshawe said. "He claims to have this new drive, but he doesn't want anyone to go nosing around it. The Space Force colonel ... what's his name? ... Manetti, that's it. Manetti asked Porter why, if he had a new invention, he hadn't patented it. Porter said that he wasn't going to patent it because that would make it available to every Tom, Dick, and Harry—his very words—who wanted to build it. Porter insists that, since it's impossible to patent the discovery of a new natural law, he isn't going to give away his genius for nothing. He said that Enrico Fermi was the prime example of what happened when the Government got hold of something like that when the individual couldn't argue."

"Fermi?" Winstein asked puzzledly. "Wasn't he a physicist or something, back in the Forties?"

"Right. He's the boy who figured out how to make the atomic bomb practical. But the United States Government latched onto it, and it took him years to get any compensation. He never did get the money that he was entitled to.

"Porter says he wants to make sure that the same thing doesn't happen to him. He wants to prove that he's got something and then let the Government pay him what it's worth and give him the recognition he deserves. He says he has discovered a new natural law and devised a machine that utilizes that law. He isn't going to let go of his invention until he gets credit for everything."
