What ever happened to harnessing motion for energy?
Posted by: C(-)ris
Date: April 09, 2021 01:55PM
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?

Self-winding watch?



Saint Cloud, Minnesota, where the weather is wonderful even when it isn't.

Semi-related: Wasn't there a digital watch available for a while that had small solar cells on the face for recharging?

GPS and wireless data are pretty energy intensive.

I remember seeing ads for solar powered Casio watches.

They had those in the 1970s.

Don't tell Seiko.

Movement and solar powered watches are very much a thing.

Other applications, I have no idea.

But unless you attach a movement powered ankle bracelet to a dog's hind leg, it's pretty much a non-starter for a GPS tracker/xmtr.





Your boos mean nothing to me, I've seen what you cheer for.

Insisting on your rights without acknowledging your responsibilities isn’t freedom, it’s adolescence.

We are a government of laws, not men.

Everybody matters or nobody matters.

When a good man is hurt,
all who would be called good
must suffer with him.

You and I have memories longer than the road that stretches out ahead.

There is no safety for honest men except
by believing all possible evil of evil men.

We don’t do focus groups. They just ensure that you don’t offend anyone, and produce bland inoffensive products. —Sir Jonathan Ive

An armed society is a polite society.
And hope is a lousy defense.

You make me pull, I'll put you down.

I *love* SIGs. It's Glocks I hate.

I had automantic (self-winding) and solar powered watches in the '70s.

(Earlier for the autos).

The Citizen Eco-Drive solar powered quartz watches my wife gave me 10 years ago are still running. The range is still being made.

It worked...somewhat. I had a Seiko Kinetic watch that I liked quite a bit. It still has a battery in it. Replacing the battery required sending the watch to Seiko...it wasn't worth the effort.

I have a Pulsar Solar that I have worn for probably 20+ years. It has never been wound nor has the internal battery been replaced. Works like a charm. (Exact date of acquisition estimated.)

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.

That is exactly the one I was thinking of.
