Random thought as Facebook presented me with a advertisement for a GPS trackable dog collar with a charging base. With my luck every time the dog got out it would be with a dead battery. I seem to remember back when wearables were starting to be a thing that everyone was talking about watches charging themselves from the motion of your arm swinging. The technology must not have panned out?

I remember seeing ads for solar powered Casio watches.

Well - I've got two Casio AL190W-1AV watches I bought on ebay 8 years ago ($20 for the pair, shipped) - no battery at all; the solar panel charges up a capacitor, which will power the watch for a few weeks after being exposed to light for a half-hour or so.
Last week, I actually found the spare one I had sitting in a closet since bought. The display was out completely, but within 15 seconds or so of being exposed to light it came back to life.
