While he talked, Ishie had been busy inserting the carefully machined piece of quartz plate that Chernov had brought, into a conglomeration of glassware that looked like a refugee from the chem lab, and flipped a switch that caused a glowing coil inside a pyrex boiler to heat a small quantity of water, which must escape through the carefully machined capillary holes in the plate he had just installed. Each jet would pass through two grids, and on towards a condenser arrangement from which the water would be recirculated into the boiler by a small pump which was already beginning to churkle to itself. "O.K.," Mike said. "I dig the magnetic resonance part. And how you're using the stolen coils. But what's this gadget?" and he pointed to the maze of glass and glass tubing. "Oh. Permit me to introduce Dr. Ishie's adaptation of a French invention of some years previous, which permits the development of high voltages by the application of heat to the evaporation of a fluid medium such as water--of which we have plenty aboard and you won't miss the little that I requisitioned--causing these molecules to separate and pass at high speed through these various grids, providing electrostatic potentials in their passage which can be added quite fantastically to produce the necessary D.C. field which...." As he spoke, Mike's finger moved nearer a knob-headed bolt that seemed to be one of the two holding the glass device to its mounting board, and an inch and a half spark spat forth and interrupted the dissertation with a loud "Yipe!" "Confusion say," Ishie continued as Mike stuck his finger in his mouth, "he who point finger of suspicion should be careful of lurking dragons! "Anyhow, that's what it does. There are two thousand separate little grids, each fed by its capillary jet, and each grid provides about ninety volts." Tombu took the opportunity to inquire, "Have you got that RF field-phase generator under control yet?" He pointed to still another section of the chassis. "Oh, yes." The physicist nodded. "See, I have provided a feedback circuit to co-ordinate the pick-up signal with the three-phase RF output. The control must be precise. Can't have it skipping around or we don't get a good alignment." There was a gurgling churkle from the innocent-looking maze as the "borrowed" aerator pump from the FARM supplies began returning the condensate back to the boiler. * * * * * Major Steve Elbertson stood on the magnetic stat-walk of the south polar loading lock, gazing along the anchor tube to Project Hot Rod five miles away. "There are no experts in the ability to maneuver properly in free fall," he told himself, quieting his dissatisfaction with his own self-conscious efforts at maintaining the military dignity of the United Nations Security Forces in a medium in which a man inevitably lost the stances that to him connotated that dignity.
