N.F.P.'s version of the battery is a thin, blackish wafer about the size of a half dollar, enclosed in protective glass. It has two electric terminals like any other bat tery, and when it is exposed to bright sunlight it generates about half a volt. A square yard of the batteries would light a 100-watt lamp or run an electric fan. A few acres would give enough power for a fair-sized town...
...Pivner's brain is a sheer pulp of newspaper headlines, self-help manuals and radio commercials ("Hi, gang! Your friend Lazarus the Laughing Leper brings you radio's newest kiddies' program, The Lives of the Saints, sponsored by Necrostyle ... Don't forget, kids, Necrostyle, the wafer-shaped sleeping pill...
...Bell Solar Battery resembles a miniature xylophone. It is made of wafer-thin strips of specially treated silicon, linked in series. Silicon is a semiconductor, i.e., under certain conditions it can be made to carry electricity...
Last week Radio Corp. of America demonstrated a sub-thimble-size radioactive battery that is somewhat more efficient. A film of Strontium 90 is spread on a wafer of silicon. When its beta particles shoot into the silicon, each of them releases 200,000 fresh electrons, which are collected as an electric current by a spot of silicon-antimony alloy...
...electric current, and their electrified liquid slowly dissolves the germanium. When they have almost drilled through the slab, leaving only a few ten-thousandths of an inch, the current is quickly reversed. The drilling stops, and the reversed current deposits metallic indium on both sides of the thin germanium wafer. The result is a transistor with two indium electrodes to which wires can be attached...
