ABSTRACT
Instantly I had this glaring flash of something so obvious a child of six could have thought of it. If a clockwork gramophone can produce that volume of sound, then why not apply the principle to building a spring-driven radio. That was the Alka-Seltzer moment, the moment the tablet hits the water and begins to fizz. I left the television set on, with the narrator still submerging viewers in a tidal wave of dismal statistics and, late as it was, went to my workshop. A good idea turns every cog in your mind, making you scared of bed in case the whole machine grinds to a halt. (Bayliss 2000: 244)
