Another would-be technical breakthrough was the Bell "phonautograph" of 1874, actually made out of a human cadaver's ear. Clamped into place on a tripod, this grisly gadget drew sound-wave images on smoked glass through a thin straw glued to its vibrating earbones.
By 1875, Bell had learned to produce audible sounds -- ugly shrieks and squawks -- by using magnets, diaphragms, and electrical current.
Most "Golden Vaporware" technologies go nowhere.
But the second stage of technology is the Rising Star, or, the "Goofy Prototype," stage. The telephone, Bell's most ambitious gadget yet, reached this stage on March 10, 1876. On that great day, Alexander Graham Bell became the first person to transmit intelligible human speech electrically. As it happened, young Professor Bell, industriously tinkering in his Boston lab, had spattered his trousers with acid. His assistant, Mr. Watson, heard his cry for help -- over Bell's experimental audio-telegraph. This was an event without precedent.
Technologies in their "Goofy Prototype" stage rarely work very well. They're experimental, and therefore half-baked and rather frazzled. The prototype may be attractive and novel, and it does look as if it ought to be good for something-or-other. But nobody, including the inventor, is quite sure what. Inventors, and speculators, and pundits may have very firm ideas about its potential use, but those ideas are often very wrong.
The natural habitat of the Goofy Prototype is in trade
