"One of them," she explained, "is the nice man who moved into the boardinghouse. He wants to take me to the movies. Did you notice that they came when it ought to be my lunchtime? He asked when I went to lunch ..." Holmes came in. He scowled. "One of my men says that one of those characters has been buying him drinks and asking questions about what we're doing." Burke scowled too. "We can let your men go home in three days more." "I'm going to start loading up," Holmes announced abruptly. "You don't know how to stow stuff. You're not a yachtsman." "I haven't got the shaft under control yet," said Burke. "You'll get it," grunted Holmes. He went out. Pam giggled again. "He doesn't want me to go to the movies with the nice man from Security," she told Burke. "But I think I'd better. I'll let him ply me with popcorn and innocently let slip that Sandy and I know you've been warned that bomb shelters won't find a mass market unless they sell for less than the price of an extra bathroom. But if you want to go broke we don't care." "Give me three days more," said Burke harassedly. "Well try," said Sandy suddenly. "Pam can fix up a double date with one of her friend's friends and we'll both work on them." Burke frowned absorbedly and went out. Sandy looked indignant. He hadn't protested. Burke got Holmes' four workmen out of the ship and had them help him roll the bronze shaft to the pit and let it down onto a cradle of timbers. Now if it moved it would have to penetrate solid earth. The most trivial of computations showed that when the bronze shaft had flown thirty miles, it hadn't done it on the energy of a condenser shorted through its coils. The energy had come from somewhere else. Burke had an idea where it was. Presently he verified it. The cores and windings he'd adapted from a transparent hand-weapon seen in an often-repeated dream--those cores and windings did not make electromagnets. They made something for which there was not yet a name. When current flows through a standard electromagnet, the poles of its atoms are more or less aligned. They tend to point in a single direction. But in this arrangement of wires and iron no magnetism resulted, yet, the random motion of the atoms in their framework of crystal structure was coördinated. In any object above absolute zero all the atoms and their constituent electrons and nuclei move constantly in all directions. In such a core as Burke had formed and repeated along the shaft's length, they all tried to move in one direction at the same time. Simultaneously, a terrific surge of current appeared in the coils. A high-speed poleward velocity developed in all the substance of the shaft. It was the heat-energy contained in the metal, all turned instantly into kinetic energy. And when its heat-energy was transformed to something else, the shaft got cold.
