Russia's most useful eavesdropping weapon is a tiny, kopeck-sized reflector. It was such a reflector, installed inside a plaque of the U.S. Great Seal in the Moscow embassy, that U.N. Ambassador Henry Cabot Lodge displayed to the Security Council last year. When an infra-red beam is aimed at the reflector from outdoors, it acts as a microphone. Alternatively, but less reliably, the infra-red beam can be trained on any imperceptibly oscillating object, such as a metal lampshade or empty highball glass, that can act as a crude reflector for conversation...
...satellite packed with electronic equipment and acting as a relay station for forwarding floods of messages almost instantaneously around the curve of the earth. Echo I, the 100-ft. balloon satellite, which is still a striking naked-eye spectacle in the sky, showed the value of a large, passive reflector from which to bounce radio waves. Transit satellites I-B and II-A were U.S. Navy prototypes for a network that will outmode all previous methods of air and sea navigation. The U.S.'s Pioneer V lived up to its name by spinning into an orbit around the sun, still...
Solar Stove. A 14-lb. aluminum-coated steel disk that cooks by focusing the rays of the sun on its grill has been developed by Los Angeles' American Landscape Products, Inc. The 32-in. reflector gathers enough heat to grill a steak in twelve minutes, boil water in two minutes. Price...
...sphere may collapse, pushed to a pancake by air drag and pressure of sunlight, or drawn together by the Mylar's "memory" of the way it was folded in the launching rocket. But a flattish or crumpled shape may continue to serve for years as a good radio reflector, which is the basic job that Echo was sent up to perform...
When the Army Signal Corps bounced the first radio signal off the moon in 1946, there were high hopes that the moon would soon serve as a reflector to angle microwave radio messages around the curve of the earth. Nothing much happened for 14 years; the practical difficulties proved considerable. But last week the Navy proudly announced the establishment of man's first practical communications system by way of the moon, linking Washington and Hawaii. To celebrate the occasion, Navy officials displayed a radio photograph sent from Hawaii via the moon, of the carrier Hancock with its crew lined...
