Last week an aspirant to the French Academy of Sciences, Dr. H. Barjot, printed in Paris his suggestion to the Academy of a temperature-differential power plant the inverse of Academician Claude's. Dr. Barjot would generate his power in Polar regions where water under the ice is 32° F. (freezing) or warmer and the air above 20° below zero or colder. He would pump sub-ice water into a surface tank partially filled with butane or some other hydrocarbon of low vaporization point. In the tank the ice water would freeze and release it? comparative heat...
...front cover} Should an ancient fire-worshipper, reincarnated, return to the contemporary U. S. scene, it is perhaps in a steel-mill that he would find his most congenial employment. For the heart of the steel-mill is the flame of its furnace, and the power of the steel-mill is the heat of that flame. Cold and solid is steel to the layman. Hot and liquid it is to the steelworker, who is essentially one of dozens of cooks attending a titan's kettle of boiling muck. To him, it seems, the fiery mess is continually boiling...
Officials of the Bureau of Standards affixed 700 stamps to envelopes, put them in a revolving barrel, turned it with electric power until the edges of the envelopes were worn off: Not one stamp left its envelope. Results: proof that there is no base for recent charges that U. S. stamps do not stick on as long as they used...
Over Lake Union, at Seattle, last week put-putted a great seaplane; its propeller moved not, its engine was dead. Motive power came from a small outboard motor affixed to the floating cabin, as to the rear end of a rowboat or canoe. Pertinent utility of the outboard motor: the seaplane can toddle to its dock without the great draft and ungainly power of its flying engine...
Getting heavy planes off the ground requires more power than flying them straightaway. Hence, attempts to shove them upward from inclined planes; hence, the device of the German Dr. Hugo Junkers, which last week's despatches reported successful. He places the plane which is to fly, on the wings of a large three-motored auxiliary plane. The auxiliary leaves the ground with its load, when good flying height is attained, the top ship takes off from the auxiliary, which returns to its field. Last week the U. S. gave Dr. Junkers letters patent for his idea...
