You know how a quartz crystal oscillator in a radio-control apparatus will break, if you work it on a very heavy load at the peak? They simply smash the crystals of metal in the same way. Only they project their field." "Then our toughest metals are useless? Can't something tough, rather than hard, like copper or even silver for instance, stand it?"
"Once arrived at the bottom, nearly six miles down, we shall attach the cable to some secure anchorage, by means of a radio-control, operated from within the bell, and then, with the bell free, we shall make explorations, as extensive as possible. The radio-control of which I have spoken governs also the attachment of the cable to the bell.
The radio-control, which is so familiar in its thousand applications to-day, was then a new thing, having been invented only a year or so before the deluge, and De Beauxchamps's form of the apparatus was crude. The underlying principle, however, was the same as that now employed transmission through a metallic wall of impulses capable of being turned into mechanic energy.
Whirling with a very soft hum hardly audible, it left her hand and floated upward across the room. Circling the casements up near the ceiling, and then heading downward straight for Elza! And I saw, too, that the woman was guiding it by a tiny radio-control. The thing was so unexpected that I stood gaping. But only for an instant.
Edison's statement, yet I ventured to remind him that several distinguished scientists had declared that the airship America could not fail to destroy the German fleet. "Pooh!" he answered. "I said the America expedition would fail. The radio-control of torpedoes is uncertain at the best because of difficulties in following the guide lights.
They were my grandmother's jewels." "But, my dear, how could he get out?" "Well, how does he get in? What's his radio-control good for; won't that help him? What is he going down there for if he can't do a little thing like that, to oblige?"
