Conant’s one great fear was that Kidder would some day take an interest in world events and begin to become opinionated. Good heavens – the potential power he had! A little matter like swinging an election could be managed by a man like Kidder as easily as turning over in bed.
The only thing he could do was to call him periodically and see if there was anything that Kidder needed to keep himself busy. Kidder appreciated this. Conant, once in a while, would suggest something to Kidder that intrigued him, something that would keep him deep in his hermitage for a few weeks. The light pump was one of the results of Conant’s imagination. Conant bet him it couldn’t be done. Kidder did it.
One afternoon Kidder answered the squeal of the radiophone’s signal. Swearing mildly, he shut off the film he was watching and crossed the compound to the old laboratory. He went to the radiophone, threw a switch. The squealing stopped. "Well?"
"Hello," said Conant. "Busy?"
"Not very," said Kidder. He was delighted with the pictures his camera had caught, showing the skillful work of a gang of Neoterics synthesizing rubber out of pure sulphur. He would rather have liked to tell Conant about it, but somehow he had never got around to telling Conant about the Neoterics, and he didn’t see why he should start now.
Conant said, "Er… Kidder, I was down at the club the other day and a bunch of us were filling up an evening with loose talk. Something came up which might interest you."
"What?"
"Couple of the utilities boys there. You know the power setup in this country, don’t you? Thirty per cent atomic, the rest hydroelectric, diesel and steam?"
"I hadn’t known," said Kidder, who was as innocent as a babe of current events.
"Well, we were arguing about what chance a new power source would have. One of the men there said it would be smarter to produce a new power and then talk about it Another one waived that; said he couldn’t name that new power, but he could describe it. Said it would have to have everything that present power sources have, plus one or two more things. It could be cheaper, for instance. It could be more efficient. It might supersede the others by being easier to carry from the power plant to the consumer. See what I mean? Any one of these factors might prove a new source of power competitive to the others. What I’d like to see is a new power with all of these factors. What do you think of it?"
"Not impossible."
"Think not?"
"I’ll try it."
"Keep me posted." Conant’s transmitter clicked off. The switch was a little piece of false front that Kidder had built into the set, which was something that Conant didn’t know. The set switched itself off when Conant moved from it. After the switch’s sharp crack, Kidder heard the banker mutter, "If he does it, I’m all set. If he doesn’t, at least the crazy fool will keep himself busy on the island."
Kidder eyed the radiophone, for an instant with raised eyebrow; and then shrugged them down again with his shoulders. It was quite evident that Conant had something up his sleeve, but Kidder wasn’t worried. Who on earth would want to disturb him? He wasn’t bothering anybody. He went back to the Neoterics’ building, full of the new power idea.
Eleven days later Kidder called Conant and gave specific instructions on how to equip his receiver with a facsimile set which would enable Kidder to send written matter over the air. As soon as, this was done and Kidder informed, the biochemist for once in his life spoke at some length.
"Conant – you implied that a new power source that would be cheaper, more efficient and more easily transmitted than any now in use did not exist. You might be interested in the little generator I have just set up.
"It has power, Conant – unbelievable power. Broadcast. A beautiful little tight beam. Here – catch this on the facsimile recorder." Kidder slipped a sheet of paper under the clips of his transmitter and it appeared on Conant’s set. "Here’s the wiring diagram for a power receiver. Now listen. The beam is so tight, so highly directional, that not three-thousandths of one per cent of the power would be lost in a two-thousand-mile transmission. The power system is closed. That is, any drain on the beam returns a signal along it to the transmitter, which automatically steps up to increase the power output. It has a limit, but it’s way up. And something else. This little gadget of mine can send out eight different beams with a total horsepower output of around eight thousand per minute per beam. From each beam you can draw enough power to turn the page of a book or fly a superstratosphere plane. Hold on – I haven’t finished yet. Each beam, as I told you before, returns a signal from receiver to transmitter. This not only controls the power output of the beam, but directs it. Once contact is made, the beam will never let go. It will follow the receiver anywhere. You can power land, air or water vehicles with it, as well as any stationary plant. Like it?"
Conant, who was a banker and not a scientist, wiped his shining pate with the back of his hand and said, "I’ve never known you to steer me wrong yet, Kidder. How about the cost of this thing?"
"High." said Kidder promptly. "As high as an atomic plant. But there are no high-tension lines, no wires, no pipelines, no nothing. The receivers are little more complicated than a radio set. Transmitter is – well, that’s quite a job."
"Didn’t take you long," said Conant.
"No," said Kidder, "it didn’t, did it?" It was the lifework of nearly twelve hundred highly cultured people, but Kidder wasn’t going into that. "Of course, the one I have here’s just a model."
Conant’s voice was strained. "A model? And it delivers—"
"Over sixty-thousand horsepower," said Kidder gleefully. "Good heavens! In a full sized machine – why, one transmitter would be enough to—" The possibilities of the thing choked Conant for a moment. "How is it fueled?"
"It isn’t," said Kidder. "I won’t begin to explain it. I’ve tapped a source of power of unimaginable force. It’s – well, big. So big that it can’t be misused."
"What?" snapped Conant. "What do you mean by that?" Kidder cocked an eyebrow. Conant had something up his sleeve, then. At this second indication of it, Kidder, the least suspicious of men, began to put himself on guard. "I mean just what I say," he said evenly. "Don’t try too hard to understand me – I barely savvy it myself. But the source of this power is a monstrous resultant caused by the unbalance of two previously equalized forces. Those equalized forces are cosmic in quantity. Actually, the forces are those which make suns, crush atoms the way they crushed those that compose the companion of Sirius. It’s not anything you can fool with."
"I don’t—" said Conant, and his voice ended puzzledly.
"I’ll give you a parallel of it," said Kidder. "Suppose you take two rods, one in each hand. Place their tips together and push. As long as your pressure is directly along their long axes, the pressure is equalized; right and left hands cancel each other. Now I come along; I put out one finger and touch the rods ever so lightly where they come together. They snap out of line violently; you break a couple of knuckles. The resultant force is at right angles to the original forces you exerted. My power transmitter is on the same principle. It takes an infinitesimal amount of energy to throw those forces out of line. Easy enough when you know how to do it. The important question is whether or not you can control the resultant when you get it. I can."
