Beverly Clock

See also Cox's Clock: https://en.wikipedia.org/wiki/Cox's_timepiece I'm sure Wikipedia used to have a much better write up, and more info on other clocks of a similar type. It's a shame they started on deleting and merging so much of the historic and esoterica - they lost a lot of accuracy and good data in the process. Now the best write up and photo is at http://www.douglas-self.com/MUSEUM/POWER/oddclocks/oddclocks...

It's not self-correcting, though, just powered by energy harvesting from atmospheric pressure changes. The Clock of the Long Now was supposed to be self-correcting. There's a mirror setup to focus the sun on some part which expands and provides a correction input. That project is decades behind schedule, although Bezos is now having one built for him on land he owns.

That's a very sloppy article right there. The lede is ridiculous, saying it is "still running... since 1864" which is contradicted in the body. The mechanism that actually powers it, not mentioned in the lede for some reason, but instead we are briefly led to believe that it was powered by a wind-up mechanism that hasn't been touched. Lastly, a rather pitiful assortment of references. This could be a better article if someone cared enough.
