...CONDITIONERS: Some units give a lot of cooling power for a dime's worth of electricity; others give less than half as much. The trick to separating the gluttons from the economizers lies in dividing a model's advertised cooling power, usually expressed in B.T.U.s (British thermal units), by its wattage. If a unit requires 2,000 watts to produce 10,000 B.T.U.s of cooling power, it has an efficiency rating of 5, and that means it is a dog. Running it on "high" for 24 hours a day, every day for a month, uses...

...message every pilot seeks is where to find updrafts, or lift, that will provide precious altitude. Lift comes in three main forms: thermals, ridge currents and mountain waves. Thermals are capricious updrafts generated by such sun-warmed spots as hilltops, deserts, parking lots and plowed fields. Large fires at garbage dumps will also do the trick. In competition, pilots try to gain altitude by rising with one thermal, then diving to another near by. They may be detected by clouds, airborne debris, hawks or odors. "Thermals pick up the odor of the ground where they form," says Lloyd Licher...
...presumably thought it safe to take a holiday in Italy to soak up some sun and get treatment for a troublesome eye condition. That, as it turned out last week, was a royal mistake. While the King was bathing his eyes with mud and mineral water at a thermal spa on the isle of Ischia off Naples, his kingdom was peremptorily converted into a republic. Leading the coup was his cousin and brother-in-law, ex-Prime Minister Sardar Mohammed Daoud Khan...

It is designed to replace the makeshift sunshade erected by the first crew to protect the orbital workshop's bare spot where it lost its thermal and meteoroid shielding...
