...over his intercom system and fielding rapid-fire phone calls: "Hello. Yes. No. Tomorrow. Fine. Goodbye." Then, dictating memos over his shoulder, he would go off on his rounds, turning up onstage to admonish a stagehand ("Don't smoke on our stage, please"), switching off the lights in sub-basement storage rooms, climbing into the uppermost rafters to check on a special staging effect...
Like a well-trained dolphin, the miniature experimental submarine maneuvered docilely around the waters of California's Santa Barbara yacht basin. No propellers, no jets were visible along its sleek, 10-ft.-long hull, yet the sub was obviously moving under its own power, gliding silently at about 2 m.p.h. 3 ft. under the surface. There was not a motor on board, but the odd little boat was being propelled by the same electrical phenomenon that causes rotors in electric motors to turn: electromagnetic force...
...storage batteries send current through a large coil wound bow to stern, inside the cylindrical section of the hull, setting up a magnetic field in the surrounding sea water. The same batteries send electric current through the salty water between two electrodes, one on each side of the sub. Because the current flows at right angles to the magnetic field generated by the coil, electromagnetic force is exerted against the conductor-which in this case is the sea water itself. As the sea water is pushed back-like the armature of a motor-the sub reacts by moving forward...
...Mechanical Engineer Stewart Way, a specialist in magnetohydrodynamics. As far back as 1958, he recalls, "I had a hankering to develop an electrical submarine without propellers or jets." But in those days there was one insurmountable problem: to develop a magnetic field strong enough to propel a full-size sub, Way calculated, would require a conventional magnet weighing 500,000 tons-almost 80 times as heavy as an entire Polaris submarine. Working out some method of propelling a small-scale experimental sub seemed a waste of time...
...climax comes at the site of the clot, where the navigator (Donald Pleasence) turns out to be an enemy agent, hijacks the sub, and tries to kill the patient by ramming a neural ganglion. Not a second too soon, Hemonaut Boyd sinks the sub with the laser gun. The villain is then devoured, head first, by a white cell that resembles a large, aggressive hominy grit. Whereupon the survivors follow the optic nerve until they squirt out of the tear duct and are rescued from a teardrop that looks like Lake Michigan. And then back, BACK, BACK to normal size...
