Chapter 9: The Irresistible and the Immovable

The generator Arcot had brought was one of the two spare generators used for laboratory work. He took it now into the sub-station, and directed the Talsonian students and the scientist in the task of connecting it into the lines; though they knew where it belonged, he knew how it belonged.

Then the terrestrian turned on the power, and gradually increased it until the power authorities were afraid of breakdowns. The accumulators were charged in the city, and the power was being shipped to other cities whose accumulators were not completely charged.

But, after giving simple operating instructions to the students, Arcot and Morey went with Stel Felso Theu to his laboratory.

“Here,” Stel Felso Theu explained, “is the original apparatus. All these other machines you see are but replicas of this. How it works, why it works, even what it does, I am not sure of. Perhaps you will understand it. The thing is fully charged now, for it is, in part, one of the defenses of the city. Examine it now, and then I will show its power.”

Arcot looked it over in silence, following the great silver leads with keen interest. Finally he straightened, and returned to the Talsonian. In a moment Morey joined them.

The Talsonian then threw a switch, and an intense ionization appeared within the tube, then a minute spot of light was visible within the sphere of light. The minute spot of radiance is the real secret of the weapon. The ball of fire around it is merely wasted energy.

“Now I will bring it out of the tube.” There were three dials on the control panel from which he worked, and now he adjusted one of these. The ball of fire moved steadily toward the glass wall of the tube, and with a crash the glass exploded inward. It had been highly evacuated. Instantly the tiny ball of fire about the point of light expanded to a large globe.

“It is now in the outer air. We make the--thing, in an evacuated glass tube, but as they are cheap, it is not an expensive procedure. The ball will last in its present condition for approximately three hours. Feel the exceedingly intense heat? It is radiating away its vast energy.

“Now here is the point of greatest interest.” Again the Talsonian fell to work on his dials, watching the ball of fire. It seemed far more brilliant in the air now. It moved, and headed toward a great slab of steel off to one side of the laboratory. It shifted about until it was directly over the center of the great slab. The slab rested on a scale of some sort, and as the ball of fire touched it, the scale showed a sudden increase in load. The ball sank into the slab of steel, and the scale showed a steady, enormous load. Evidently the little ball was pressing its way through as though it were a solid body. In a moment it was through the steel slab, and out on the other side.

“It will pass through any body with equal ease. It seems to answer only these controls, and these it answers perfectly, and without difficulty.

“One other thing we can do with it. I can increase its rate of energy discharge.”

The Talsonian turned a fourth dial, well off to one side, and the brilliance of the spot increased enormously. The heat was unbearable. Almost at once he shut it off.

“That is the principle we use in making it a weapon. Watch the actual operation.”

The ball of fire shot toward an open window, out the window, and vanished in the sky above. The Talsonian stopped the rotation of the dials. “It is motionless now, but scarcely visible. I will now release all the energy.” He twirled the fourth dial, and instantly there was a flash of light, and a moment later a terrific concussion.

“It is gone.” He left the controls, and went over to his apparatus. He set a heavy silver bladed switch, and placed a new tube in the apparatus. A second switch arced a bit as he drove it home. “Your generator is recharging the accumulators.”

Stel Felso Theu took the backplate of the control cabinet off, and the terrestrians looked at the control with interest.

“Got it, Morey?” asked Arcot after a time.

“Think so. Want to try making it up? We can do so out of spare junk about the ship, I think. We won’t need the tube if what I believe of it is true.”

Arcot turned to the Talsonian. “We wish you to accompany us to the ship. We have apparatus there which we wish to set up.”

Back to the ship they went. There Arcot, Morey and Wade worked rapidly.

It was about three-quarters of an hour later when Arcot and his friends called the others to the laboratory. They had a maze of apparatus on the power bench, and the shining relux conductors ran all over the ship apparently. One huge bar ran into the power room itself, and plugged into the huge power-coil power supply.

They were still working at it, but looked up as the others entered. “Guess it will work,” said Arcot with a grin.

There were four dials, and three huge switches. Arcot set all four dials, and threw one of the switches. Then he started slowly turning the fourth dial. In the center of the room a dim, shining mist a foot in diameter began to appear. It condensed, solidified without shrinking, a solid ball of matter a foot in diameter. It seemed black, but was a perfectly reflective surface--and luminous!
