Most cooking methods-baking, boiling, frying-date from stone-ax days. They all heat food from the outside in. The Raytheon Co., prolific spawner of radar tubes, has shown short-order cooks something new; a "range" which cooks food from the inside...
...Raytheon expects airlines to be the first big "Radarange" buyers. Quick lunch restaurants are prospects too. Radarange will grill a hamburger sandwich or a hot dog in 35 seconds. It bakes foam-light cup cakes, biscuits, or gingerbread in 29 seconds. It shuts itself off automatically...
Radarange is still too expensive for the home. But eventually, Raytheon hopes, a housewife will be able to slip a pot roast into the range and rush it to the table before her homecoming husband has parked his overcoat. For rare roast beef, rich brown outside, warm pink within, he will have to wait awhile: it is still beyond Radarange...
Like the short radio waves (about 80 megacycles) now used for television, microwaves (over 300 megacycles) cannot be sent beyond the horizon. But Raytheon's engineers say that microwaves have two advantages for transmitting pictures: 1) they can be relayed more easily, by means of automatic pickup and amplifying stations in towers about 30 miles apart, and 2) they can carry a picture on a narrower band in the spectrum, thus providing a great many more channels for transmission...
...Raytheon plans to use a system of automatic transmission of microwaves along such a chain of towers, as an alternative to the expensive coaxial cables used in television. Raytheon's broadcasting stations will scan a wide area, transmit what they see from coast to coast...
