Re: Batteryless radio
If I recall correctly there was a clever wrinkle in Bayliss’s design (or it may have been a second generation of the original) which basically added an electronic/electrical element to a traditional clockwork escapement which basically provided PWM regulation of the output. This made the whole thing vastly more efficient and provided a much longer run-time from the same spring compared previous “open loop” regulation mechanisms which ran the generator at constant speed and threw away any excess power generated through an old-school analog regulator...
