There is a clockwork wind-up radio available for survivalists -- wind
up electronic devices are obviously possible. It's just whether it's
efficient, where batteries are easily available and otherwise practical.
I wonder if a "self-winding" mechanism would be more practical?
They've been proven in wrist and pocket watches for centuries, and
the bugs are all worked out. I wonder if something larger would
be practical? (or arrays of small ones)
I also wonder if Seiko ever released the specs for their electronic
self-winding watch? I think it was just a crude generator coil
hooked into the same self-winding flywheel -- but saying something
by Seiko is crude is not exactly natural. Seiko watches always had
a high degree of precision.
Scaling it up...
Does anyone know if a self-winding mechanism was ever put on a full
sized clock? Something like a ship's chronometer would have been
a natural, since the movement on the water would have kept it wound.
