...Germanium Crop. Dr. Hans Brauchli of Johns Hopkins University is one of many scientists who have been ransacking the earth for germanium, the rare and elusive metal that is made into transistors...
...knew that certain kinds of coal contain small amounts of it, probably concentrated in some way by the ancient plants that coal is made of. So Dr. Brauchli analyzed the ash of modern plants that grow in parts of the eastern U.S. where the water shows faint traces of germanium. He found that some plants, mostly from swampy areas near mountains, have as much as 5% of the metal in their ash. Apparently they "discard" the germanium, depositing it in outlying parts, such as leaves and bark. Dr. Brauchli believes that it might be profitable, in favored spots, to grow...
...demonstrated new applications for the germanium transistor, which can be used in place...
Transist-Ear. Minneapolis' Maico Co. will begin sale next month of a hearing aid the size of a cigarette lighter which weighs only 2½ oz. Three germanium transistors take the place of vacuum tubes for amplification, and in place of conventional batteries, Transist-Ear's power comes from a mercury capsule the size of a dime, good for 75 hrs. Replacement capsules cost about 25?. Price: around...
Electronics men are especially fond of transistors, those wondrous specks of germanium that perform like vacuum tubes while demanding almost no current and generating almost no heat (TIME...
