Three times the airplane dragged the "sleeve" target, at the end of a 2,000 ft. line, across the sky. Once it was not fired upon because both ship and target were too close to the sun. Once only two guns of the battery had firing data from the new electrical automatic range-finding apparatus. Spectators at the show-the 11th annual meeting of the Army Ordnance Association-later learned that the total of 200 rounds fired had made only a score of shrapnel tears in the red cloth finger. Previously they had seen two four-gun, multiple-mounted...
Coincident with his 47th birthday last week, Professor Robert Hutchings Goddard, Clark University rocket inventor (TIME, July 29), disclosed his invention of a sun engine. His laboratory model consists of a parabolic mirror one foot in diameter, which focuses sunlight upon a hollow glass sphere five-eighths of an inch in diameter. The sphere contains water and finely divided carbon. The focused light passes through the clear water without heating it. But when the light strikes the opaque carbon, the carbon heats almost instantly and in turn heats the water, which turns to steam. The steam escapes through a hole...
...would contain, instead of pulverized carbon, mercury sprayed continuously at the focus point of the reflected light. The mercury spray would turn instantly to mercury vapor and in turn vaporize the water which would operate a steam turbine. The turbine would operate an electric generator. Efficiency of such a sun engine would be 50% of the sun energy fused.* Professor Goddard calculates that such an engine would produce 30 h.p. while operated under a clear sky between 10:00 a.m. and 3:00 p.m., when sunlight is strongest in the U. S. If storage batteries were used, the owner could...
Director Dr. Charles Greeley Abbott of the Smithsonian Institution has worked on sun engines. There is one, the Eaneas, working at low efficiency at Pasadena, Calif. At Meadi, near Cairo, Egypt, the Shumann engine produces 60 h.p. Its reflectors cover an acre. If an efficient and practical sun engine can be built, its sun source of energy is not only free but stupendous in quantity. The energy falling on a square mile of earth on a bright sunny day with a clear atmosphere is equivalent to two or three million horsepower. According to Dr. Abbott the sun energy reaching...
...Significance. The boredom and inertia so frequent in Author Hemingway's The Sun Also Rises (TIME, Nov. 1, 1926) never occur in A Farewell to Arms. He has gone back to the cause of that weariness-the desolating conflict of nations. In that time bravery and rapture were gloriously commonplace, scarcely aware of the exhaustion which was to follow...
