...small, probably a cylinder a few feet in diameter, but it will have to generate something like 100 times the energy of the massive reactor of Britain's Calder Hall nuclear power station. This means that it will run very hot, and will be kept from flashing into vapor only by the stream of liquid hydrogen forced rapidly through it. On the other hand, the core need work for only a few minutes. By that time the propellant will have been exhausted, and the rocket will be on its way into deep space...
...During launching and reentry, the space pilot will have his pressure suit inflated. In relaxed, straightaway flight, he will be able to deflate his suit, open his visor and rely on cabin air. The air will be filtered, probably through lithium hydride, to remove carbon dioxide and excess water vapor from breath and sweat. It will also be cooled and deodorized...
...series of thin marble cutouts, rubbed pebble-smooth, that sometimes suggest chic mannequin sil houettes, and sometimes ancient Gaulish coins. Hajdu also produces metal bas-reliefs, which he calls "orchestrations of light and shade," that bring to mind the pulsations of a Spanish dance or the interlocking vapor trails of high-flying jets. At best they reflect the inspiration he found in the art of ancient Mesopotamia, to create a world "real in facts but invented in forms...
...surface burns off, leaving a mat of silica fibers arranged so that they cannot be easily blown away. At 3,000° F. (about the melting point of iron), they begin to soften, but melted silica is sticky, viscous stuff that clings tight until it turns to vapor. The vaporizing process draws heat from the remaining Astrolite and tends to keep it cool...
...converter is made of two plates of tungsten that are a fraction of a millimeter apart. Between them is a vapor in near vacuum. The plates are so treated that they have different electric potentials. (G.E. will disclose neither the vapor nor the method of treating the plates.) The plate with the higher potential is heated to about 1,500° centigrade, the other to around 1,000° centigrade. The first plate is hot enough to release electrons; the second is not. Clouds of electrons boil off the hotter plate (the cathode) and are attracted to the cooler plate...
