...probable compositions (mainly hydrogen and helium), Russell concludes that 1) its diameter is perhaps 216,000 miles, or 40% that of its star-"big for a planet, but passable"; 2) its surface temperature is probably somewhere between 50 and minus 168 degrees Centigrade (122 to minus 272 degrees Fahrenheit...
...water furnishing the power. Advantage of the high-pressure, high-temperature turbine is that it makes the blades spin faster and more powerfully with less expenditure of fuel. In the newest Navy ships, the steam, under pressure of 600 lb. per square inch, is superheated to 850° Fahrenheit...
...using up its fuel supply at an increasing rate, will gradually get hotter during the next ten billion years. By that time the earth's surface temperature will be lifted to about 750° Fahrenheit, hot enough to boil away the oceans, char organic matter, and melt tin, lead and zinc. Then the last of the sun's hydrogen atoms will be converted into helium. With no more fuel on hand, the sun will cool and fade...
...problem of keeping warm high up is less critical. Temperatures of almost -70° Fahrenheit are encountered at extreme altitudes, but electrically heated suits have proved fairly satisfactory...
...developing equipment to send planes toward the stratosphere, whither the air battles of World War II are rapidly climbing. The refrigerated wind tunnel, an enormous doughnut 25 feet across, made of tubing three feet in diameter, contains a 300-m.p.h. wind that blows at temperatures down to -90° Fahrenheit...
