...high temperature (which favors efficiency) without high pressure, another reactor will have heat-resistant graphite as its moderator and will be cooled by a molten sodium-potassium alloy. Still another will have a novel gimmick. Its cooling water will be allowed to boil, and the steam generated will be used directly to drive a 5,000-kw. turbine. This cuts out the conventional heat exchanger used in the reactor of the submarine Nautilus to generate nonradioactive steam. Dr. Smyth did not say so, but the turbine will probably become so radioactive that it cannot be approached by humans...
...Britain's B.E.A.M.A. (British Electrical and Allied Manufacturers' Association) Journal, Engineer F. T. Bacon of Cambridge describes the most hopeful approach so far to a practical fuel cell. Bacon uses two diaphragms of porous nickel set close together with an electrolyte (a solution of potassium hydroxide) between them. Hydrogen gas at the pressure of 800 Ibs. per sq. in. seeps through one diaphragm, oxygen through the other. They combine in the electrolyte, and the energy of their "burning" appears as electricity, not as heat...
After careful discussion of the matter with Roommate Wepman, a Miami attorney's son with vague literary pretensions, Chemist Fraden decided to use potassium cyanide as a terminal agent. One evening last August, he put a vial of the stuff in his pocket, got a bottle of champagne, called on his parents and joyously announced that he had got a job. He poured three glasses of wine, added cyanide to two of them, and asked his parents to join him in a toast to his future. They drank and toppled to the floor...
...many other human bones found throughout Europe. The jawbone, according to the scientists' report in the British Museum Bulletin, fared even worse: it proved to be the jaw of a modern ape, probably an orangutan, which died at the age of ten. It had been artificially colored with potassium bichromate and an iron salt to make it look old, and its teeth had been pared to make them look more or less human. Unanswered still was the question of who had planted the fake. Dawson, who died in 1916 and whose monument stands near the Piltdown gravel...
...needs fat and carbohydrates from food to provide calories. He starts to take up nitrogen and rebuild muscle protein at the same prodigious rate as a one-year-old (suggesting that the growth hormone may have been switched on). The need for sodium goes down, while that for potassium goes up. Weeks or months later, the body replaces its store...
