...General Electric researchers, who for years have studied lightning bolts striking Manhattan's Empire State Building, showed more interest last week in hydrogen-cooling for generators at the powerhouse. Since hydrogen is the lightest of all gases, it circulates with much less friction than air. As a result of cooling generators by hydrogen rather than air, the power output per pound of fuel is increased by 20%, and the fuel saving on a 200,000-kilowatt unit tots up to $20,000 a year. There is no fire or explosion hazard, because oil seals keep the hydrogen purity...
...which it is difficult to find the real beginning of anything, and he is sure that too many textbooks attach personal labels to epochal discoveries. No one has the faintest idea who invented the wheel, the pulley, the boat, the sail. And who really invented those later marvels, the friction match, the barometer, the airplane, the steamboat...
NACA's research director, Dr. George William Lewis, was proudest of a new wing developed during the past year. Approximately one-half the drag, i.e., the speed-killing characteristic, of the modern airplane is caused by its wings. Most of the wing drag is caused by air friction along the surface which, as the plane speeds through the air, changes from a smooth or laminar flow near the leading edge to a tumbling, churning turbulence farther back on the wing...
...replaced Irving with Corky Cornelius, who, while he plays just as loud as Irving did, has many more ideas . . . Next item of interest is that Bob Zurke is leaving Bob Crosby to form his own band and to record for Victor. While it's true that there was some friction between Bob and the other members of the band, readers must remember that the big booking agencies are getting grey hairs trying to find new bands to fill the spots which are opening for name band attractions, and that every effort is being made to entice good side-men away...
...troubles of cantankerous "problem children," but rather of boys who are meeting their obligations with reasonable success. If the University recognizes the validity of the Study material, if it studies the every-day problems of every-day individuals, it may be able to lubricate those many points of friction constantly developing in administrative machinery...
