I knew some of them ...but learned a fair bit too...

The Beverly Clock (6:36) has come no closer to being a perpetual motion machine than any other that attempted to be one.

Except it doesn't "pretend" to be one at all :roll:
or did you miss that salient point. :coffee:

6:36 "It's the closest anyone has ever come to creating a perpetual motion device..."
As I said: "The Beverly Clock has come no closer to being a perpetual motion machine than any other that attempted to be one."

Even though I provided a pointer to the exact moment in the commentary that I objected to, you missed mine.

No point to miss ...it wasn't pretending to a PMM.....yours was just an inane comment.

The clock is a fascinating device harnessing the energy of atmospheric changes to avoid winding.
A barometer has no pretence of PMM nor does the clock... :roll:

Atmos clock

Jaeger-LeCoultre's Atmos clock on display.
Atmos is the brand name of a mechanical torsion pendulum clock manufactured by Jaeger-LeCoultre in Switzerland which does not need to be wound manually. It gets the energy it needs to run from temperature and atmospheric pressure changes in the environment, and can run for years without human intervention.
The clock is driven by a mainspring, which is wound by the expansion and contraction of liquid and gaseous ethyl chloride in an internal hermetically sealed bellows. The ethyl chloride vaporises into an expansion chamber as the temperature rises, compressing a spiral spring; with a fall in temperature the gas condenses and the spring slackens.[1] This motion constantly winds the mainspring. A temperature variation of only one degree in the range between 15 °C (59 °F) and 30 °C (86 °F), or a pressure variation of 3 mmHg, is sufficient for two days' operation.

Read the comment I objected to already. FFS, after pointing to it, which didn't work because you didn't follow the pointer up, I even quoted it to you, hoping that you will at least read it. No such luck.

And don't put words in my mouth. I never used the word "pretend". Additionally, I mentioned "other [machines] that attempted to be one."

Your misses are getting boring really fast.
