...already discussing a preliminary contract. Sky stations could support search radars to watch for aircraft around the curve of the earth. A chain of them acting as microwave repeaters could carry TV programs and telephone conversations across continents and oceans. Fitted with big glass bulbs filled with neon or xenon gas, which glows red or blue when microwaves pass through it, they could serve as stratospheric lighthouses to guide aircraft flying above the clouds...
...interests were scientific. At 17 he built and flew a glider. At 18 he received the rare honor of working in the laboratory of the great chemist Sir William Ramsay. At 22 he read a science paper before the Royal Society (title: The Critical Constants and Orthobaric Densities of Xenon). Soon after the outbreak of World War I, young Cripps was recalled from driving a truck in France, rose to be assistant superintendent of "the largest explosives factory in the British Empire...
...afterglow of the gases they caught in a spectroscope. They found the colors to be not only those of excited oxygen and nitrogen, the most plentiful components of the air, but also of helium, which makes up only .0005% of the atmosphere and is exceeded in scarcity only by xenon. Conclusion: there is probably lots of helium in the upper atmosphere...
Since the first explosion reverberated through the world's laboratories, the fission of thorium, as well as uranium, has been demonstrated. Atom-wranglers at Columbia University have shown that, under various conditions, the fission of uranium yields krypton, strontium, iodine, xenon, tellurium as disintegration products. The flood of reports made it appear that atomic physicists are off on the biggest big-game hunt since the discovery of artificial radioactivity was announced...
...quarts of air there is one quart of krypton. An inert gas discovered in 1898 by Ramsay and Travers, krypton is scarcer and less volatile than argon, neon and xenon; its name means "the hidden one." In the U. S., small quantities of krypton have been obtained by Linde Air Products Co. and Air Reduction Co. during the fractional distillation (selective boiling) of liquid air, and sold to academic laboratories for $100 a litre if pure, $15 a litre if mixed. Argon or nitrogen at low pressure are the usual fillers for electric tamp bulbs manufactured...
