The interior was, to put it mildly, luxurious and ultra-modern. Smooth, flowing instrument panels and storage lockers molded into the walls, foam-rubber chairs growing out of the decks, bunk-seats sunk into the bulk-heads, and transparent-topped tables sprouting their chrome frames from the fore and aft lounge decks. They finished it up with a small lavatory and an electric hot-plate in the bulk-head cubicles just off the forward lounge. Finally, transparent plexiglass was fitted into the long port-hole slots along the hull, and a large plexiglass dome was mounted over the control pit above the smoothly tapered nose. Then they papered the plexiglass and manned a spray-gun, giving the entire outer skin a thorough coat of shimmering black lacquer. The complete construction took all of six weeks working from dawn to well after sunset. When it was finished, Smitty took the truck and went into Stockton to purchase the three automobile batteries which would be used to power the ship. That night, Morrow sat at his drafting table scrawling rough diagrams and pencilling in mathematical notations around them and on the back of the papers. His table lamp threw a bright pool of light in the corner of the dark, shadowy workshop. The night was completely silent, save for the distant sighing of the wind through the pines outside, the faint scratching sound of his pencil, and the clicking and whispering of the slide-rule in his hands when he paused to compute some factor in the diagrams. Building and weight-testing the gravitors that went into the ship had led to speculation of other possible uses of the mechanisms. The possibilities were many, and Morrow spent his spare-time working them out. His ability, however, was limited. First, there was the electronic efficiency of the gravitors, the increased power gained from battery storage-cells, the decreased loss of power within the circuits and mechanism. If electrons worked more efficiently in a gravitor's field, then mechanical and chemical power might work just as well. It appeared, on paper, that a small, one-horsepower gasoline engine might deliver the equivalent of a hundred horsepower or more in electrical energy, if it were incorporated into a gravitor field. Morrow worked this "gravitor engine" out the best he could, cursing his lack of knowledge in mechanical engineering. It might work, but he didn't have the knowledge to tell exactly how it could be made. It wasn't his line.
