Robert Heinlein - Expanded Universe

"Oh, no, I didn't say that. You use the breeder pile to make the fuel, then you use the fuel anywhere and anyhow you like, with something like ninety - two percent recovery of energy. But you could junk the power sequence, if you wanted to."

King's first wild hope of a way out of his dilemma was dashed; he subsided. "Go ahead. Tell me about it."

"Well - it's a matter of artificial radioactives. Just before I asked for that special research allotment, Erickson and I - Doctor Lentz had a finger in it too," he acknowledged with an appreciative nod to the psychiatrist, " - found two isotopes that seemed to be mutually antagonistic. That is, when we goosed 'em in the presence of each other they gave up their latent energy all at once - blew all to hell. The important point is we were using just a gnat's whisker of mass of each - the reaction didn't require a big mass to maintain it."

"I don't see," objected King, "how that could - "

"Neither do we, quite - but it works. We've kept it quiet until we were sure. We checked on what we had, and we found a dozen other fuels. Probably we'll be able to tailor - make fuels for any desired purpose. But here it is." He handed him a bound sheaf of typewritten notes which he had been carrying under his arm. "That's your copy. Look it over."

King started to do so. Lentz joined him, after a look that was a silent request for permission, which Erickson had answered with his only verbal contribution, "Sure, doc."

As King read, the troubled feelings of an acutely harassed executive left him. His dominant personality took charge, that of the scientist. He enjoyed the controlled and cerebral ecstasy of the impersonal seeker for the elusive truth. The emotions felt in his throbbing thalamus were permitted only to form a sensuous obbligato for the cold flame of cortical activity. For the time being, he was sane, more nearly completely sane than most men ever achieve at any time.

For a long period there was only an occasional grunt, the clatter of turned pages, a nod of approval. At last he put it down.

"It's the stuff," he said. "You've done it, boys. It's great; I'm proud of you."

Erickson glowed a bright pink, and swallowed. Harper's small, tense figure gave the ghost of a wriggle, reminiscent of a wire - haired terrier receiving approval. "That's fine, Chief. We'd rather hear you say that than get the Nobel Prize."

"I think you'll probably get it. However" - the proud light in his eyes died down - "I'm not going to take any action in this matter."

"Why not, Chief?" His tone was bewildered.

"I'm being retired. My successor will take over in the near future; this is too big a matter to start just before a change in administration."

"You being retired! What the bell?"

"About the same reason I took you off watch - at least, the directors think so."

"But that's nonsense! You were right to take me off the watch - list; I was getting jumpy. But you're another matter - we all depend on you."

"Thanks, Cal - but that's how it is; there's nothing to be done about it." He turned to Lentz. "I think this is the last ironical touch needed to make the whole thing pure farce," he observed bitterly. "This thing is big, bigger than we can guess at this stage - and I have to give it a miss."

"Well," Harper burst out, "I can think of something to do about it!" He strode over to King's desk and snatched up the manuscript. "Either you superintend the exploitation, or the Company can damn well get along without our discovery!" Erickson concurred belligerently.

"Wait a minute." Lentz had the floor. "Doctor Harper... have you already achieved a practical rocket fuel?"

"I said so. We've got it on hand now."

"An escape - speed fuel?" They understood his verbal shorthand a fuel that would lift a rocket free of the earth's gravitational pull.

"Sure. Why, you could take any of the Clipper rockets, refit them a trifle, and have breakfast on the moon."

"Very well. Bear with me... ." He obtained a sheet of paper from King, and commenced to write. They watched in mystified impatience. He continued briskly for some minutes, hesitating only momentarily. Presently he stopped, and spun the paper over to King. "Solve it!" he demanded.

King studied the paper. Lentz had assigned symbols to a great number of factors, some social, some psychological, some physical, some economic. He had thrown them together into a structural relationship, using the symbols of calculus of statement. King understood the paramathematical operations indicated by the symbols, but he was not as used to them as he was to the symbols and operations of mathematical physics. He plowed through the equations, moving his lips slightly in subconscious vocalization.

He accepted a pencil from Lentz, and completed the solution. It required several more lines, a few more equations, before they cancelled out, or rearranged themselves, into a definite answer.

He stared at this answer while puzzlement gave way to dawning comprehension and delight.

He looked up. "Erickson! Harper!" he rapped out.

"We will take your new fuel, refit a large rocket, install the breeder pile in it, and throw it into an orbit around the earth, far out in. space. There we will use it to make more fuel, safe fuel, for use on earth, with the danger from the Big Bomb itself limited to the operators actually on watch!"

There was no applause. It was not that sort of an idea; their minds were still struggling with the complex implications.

"But Chief," Harper finally managed, "how about your retirement? We're still not going to stand for it."

"Don't worry," King assured him. "It's all in there, implicit in those equations, you two, me, Lentz, the Board of Directors and just what we all have to do about it to accomplish it."

"All except the matter of time," Lentz cautioned.

"You'll note that elapsed time appears in your answer as an undetermined unknown."

"Yes.. . yes, of course. That's the chance we have to take. Let's get busy!"

Chairman Dixon called the Board of Directors to order. "This being a special meeting we'll dispense with minutes and reports," he announced. "As set forth in the call we have agreed to give the retiring superintendent two hours of our time."

"Mr. Chairman - "

"Yes, Mr. Strong?"

"I thought we had settled that matter."

"We have, Mr. Strong, but in view of Superintendent King's long and distinguished service, if he asks for a hearing, we are honor bound to grant it. You have the floor, Doctor King."

King got up, and stated briefly, "Doctor Lentz will speak for me." He sat down.

Lentz had to wait for coughing, throat - clearing, and scraping of chairs to subside. It was evident that the Board resented the outsider.

Lentz ran quickly over the main points in the argument which contended that the bomb presented an intolerable danger anywhere on the face of the earth. He moved on at once to the alternative proposal that the bomb should be located in a rocket ship, an artificial moonlet flying in a free orbit around the earth at a convenient distance - say fifteen thousand miles - while secondary power stations on earth burned a safe fuel manufactured by the bomb.

He announced the discovery the Harper - Erickson technique and dwelt on what it meant to them commercially. Each point was presented as persuasively as possible, with the full power of his engaging personality. Then he paused and waited for them to blow off steam.

They did. "Visionary - " "Unproved - " "No essential change in the situation - " The substance of it was that they were very happy to hear of the new fuel, but not particularly impressed by it. Perhaps in another twenty years, after it had been thoroughly tested and proved commercially, they might consider setting up another breeder pile outside the atmosphere. In the meantime there was no hurry. Only one director supported the scheme and he was quite evidently unpopular.
