...Boulris is back on the beam again this afternoon, the varsity may give Yale's rather undistinguished pitching staff a rough time. The Eli hurlers who were on display here three weeks ago showed a lot of windup but very little in the way of dazzling pitching...
...heart of Raytheon's projected system is an "Amplitron" tube, a chunky object 2 ft. high. The tube transmits as much as 25 h.p. on a beam of 10 cm. waves shot into the air by a dish antenna. A nest of these tubes can be focused at a point about 50,000 ft. up. Some of the beams' energy will wander off into space, but Raytheon scientists believe that a saucer-shaped receiver can capture 35% to 50%. Turned into heat, this energy could drive a gas turbine which would drive the helicopter blades...
Conferring with helicopter people, Raytheon's scientists concluded that a sky station will have to leave the earth under ordinary chemical power and buzz its way up to the spot where the power beams come to a focus. Then its microwave-fueled engine will take over. Test prototypes will carry a human crew, but later models will be automatic. Once they have been maneuvered into the focal spot, they will be kept there by electronic devices which sense when they are beginning to drift out of it. If the supporting beam fails, the station will drift down gently, supported...
...result of Dr. Johnson's experience, crewmen of Galveston (and ships being similarly equipped) are now protected against overexposure to high-energy radar beams by a simple device: on his uniform, each man has a little neon lamp, which glows when he is exposed to danger. At the warning glow, all he has to do is step aside, out of the beam's path...
