What device (thing with at least one moving part) in constant motion, has given the longest service?
lisab said:You mean with only original parts?
[/URL]Andre said:That's a bit ambigeous, would there be maintenance carried out, are worn down and corroded parts replaced? Anyway, these things lasts milleniums:

http://en.wikipedia.org/wiki/Salisbury_cathedral_clockThe Salisbury Cathedral clock, a large iron-framed clock without a dial located in the aisle of Salisbury Cathedral. The clock dating from about 1386 is the oldest working clock in the world. The clock is one of the group of 14th to 16th century astronomical clocks to be found in the West of England. (See also Wells, Exeter, Ottery St Mary, and Wimborne Minster.) It can be dated to around 1386, and most of the parts are original.

The filament vibrates, therefor, it moves.lisab said:binzing, I swear you and I have resonant brain waves sometimes. I had this same thought, but since there are no moving parts I didn't post it.
Danger said:What the hey?! You're a Canuck too?
Astronuc said:I'd vote for the Solar System - sun, planets, moons. Continuous motion, as far as we know, since before humanity, something on the order of 4-5 billion years. And no lubrication or adjustments required.
Before the solar system would be the galaxy in which we are located - billions of years older.
One did not specify if the device was natural or not.
I think BIG!wolram said:Give some people an inch and they will take billions
~christina~ said:LOL I thought of this...not sure if it can be called service though. http://en.wikipedia.org/wiki/Drinking_bird

Danger said:If I give W an inch, I tell her that it's 6...
tribdog said:why are you giving wolram any inches?
wolram said:LOL, you guys exaggerate the smallest things.
wolram said:Mean while back to the thread.
Danger said:'W' is the PF name for my wife. I refer to Wolram as 'Woolie'.
I'm sure that's not the only reason.tribdog said:what a fool I am for really thinking you were having sex with wolram.
tribdog said:<sarcasm>really? what a fool I am for really thinking you were having sex with wolram. </sarcasm>
Danger said:I'm sure that's not the only reason.
wolram said:Bloody H---, he would have to have the longest Thingy wotsit in the world to have sex with me, Besides i like Danger very much but only as a friend.
"Longest Service: Continuous Device Motion" is a measurement that tracks the duration of a device's continuous movement without interruption.
This measurement is typically measured in hours or days, depending on the device's capabilities and the specific needs of the study or experiment.
Any device that is capable of tracking continuous movement can be used, such as fitness trackers, smart watches, or even smartphones.
Tracking this measurement can provide valuable data for understanding an individual's activity level and patterns, which can be useful for health and fitness research, as well as for monitoring patients with certain medical conditions.
One limitation is that it may not accurately reflect all types of movement, such as activities that involve little or no arm movement, like cycling. Additionally, the accuracy of the measurement may vary depending on the device's sensitivity and the individual's movement patterns.
