First message sent with atomic battery powerIn 1954, to demonstrate to reporters the functionality of the atomic battery newly developed by RCA (Radio Corporation of America), chairman David Sarnoff used the electricity it generated to produce a sound message. With a telegraph key in circuit with the battery and an ordinary telephone amplifier he tapped out two sentences: “Atoms for peace. Man is still the greatest miracle and the greatest problem on this earth.” The tone was faint, but distinct. The slim battery was made from two wafers. One was of a radioactive strontium metal against another of silicon. The particles bombarding the atoms in the silicon crystal released electrons that provided a small current of electricity. A 20-year half-life was expected for the battery. The inventors at RCA were Ernest G. Linder and Paul Rappaport.« |
