    • Ingenious as the system is, it could not compete with contemporary electrical systems. The flood merely exposed one of the weaknesses of maintaining a large scale system of pressurized air pipes. Electric (not electronic) wires were/are much simpler and cheaper to install and service, with very little impact on infrastructure. The self winding clock company in America also had the advantage of being able to synchronize individual clocks with observatory time over telegraph wires already in place. Like the canal system vs. the railway, it was really obsolete as soon as it was perfected, and I'm surprised it lasted four decades.

    • there are simple clocks that use the frequency on the power grid to tick the clock forward. When the grid is under peak load during daytime the frequency slow down when the power station machinery is under load. They use the night time to "catch up" and run with higher frequency. Most simple cheap office clocks, and clocks in schools and other public buildings are of this type and should keep the time if not damaged. ( or a power outage )

    • Doing some basic back-of-the-enveloped calculations and making reasonable assumptions about the number of subscribers, the size of the network, and the expected losses, I am not sure I believe that there only is a single central source for all the compressed air. But I absolutely can believe that there is a single authoritative time source. As for a network of auxiliary compressors, it would be trivially easy to build repeating stations every so often. All you have to have is a reliable source for compressed air, and a valve that opens and closes whenever it detects a pulse from the master clock. And since this is the age of early electrification and of ubiquitous steam engines, we can assume that producing compressed air is a solved problem. So, it is plausible that the distribution network included some sort of repeaters as it expanded over larger parts of the Paris metropolitan region. With only marginally more effort, you could even build a mechanical "reclocking" device that regenerates the 20:40 duty cycle of the signal. You'd still obtain the sequence of pulses from the central clock, but you would regenerate the actual timing of each individual pulse from scratch. All of this can be done with straight-forward mechanical components. The beauty of this system is that the duty cycle doesn't need to be super precise, and neither does anybody care about phase shift nor jitter. So, a lot of problems that modern time-keeping solutions spend enormous resources on (c.f. atomic clocks and GPS) are completely out of scope and don't need to be addressed. The only thing that matters is generating precisely 1440 pulses of approximately 20s per day. And that's easy to do with a mechanical repeater.

    • @@cardboardboification I am sure that small leaks are actually part of the design requirements. The most basic design would use bellows in each subscriber's device that are somewhat leaky. This not only ensures that the bellows won't explode when the 20s pulse keeps inflating an already full airbladder, it also means that you don't need to add any extra mechanical components to deflate the bellows. 40s should be enough for air to leak out. The beauty of this system is that it is very tolerant of variations in bladder performance and variations in absolute flow rate.

    • @ke I dunno. Thousands of tiny leaks add up, and compressed air isn't free. They'd want to limit leaks to keep down the necessary size of the compressor's engine, and the fuel it would consume. You could put some sort of pressure switch into each clock, so that when the pressure falls, it opens a relief valve for the bellows. That's not in the design animated here but that seems like a simplification. They might just de-pressurise the system at the control centre. Have the outlet pipes connected to pressure for 20 seconds, then just connect them to an exhaust pipe for the other 40, let those little weights in all those clocks push the air back out again. If the pressure can reach every clock in 20 seconds, they should all be able to exhaust back to ambient in 40. You could keep the bellows from exploding with another valve activated by the bellows when they inflated to be high enough to trip a switch. Or else just do what pressure cookers do, for emergencies, have an outlet valve with a weight on it connected to the bellows, if pressure gets high enough to lift the weight, air escapes.

Keep in mind those transistors are only a few atoms across, so sensitive than quantum mechanics can cause electrons to just teleport to places they shouldn't be. The machines that make them are so sensitive to vibrations, a truck driving by outside would cause the chips to be ruined. There was *some* simplicity to them back in the days of electron tubes and relays, but as soon as it went digital it became a manufacturing marvel.

    • It's an interesting debate. I found myself thinking of all the electronic innovations to minimize difficulties and randomness, of which binary is possibly the very biggest. Designing an 8- or 16-bit computer in the 80s was relatively simple. Clock speeds were so low, you hardly had to know anything about the actual behaviour of electricity. However, there was genius behind that simplicity; I'm still baffled when I think about how binary logic and 2s-complement math were invented. And as speeds increased and the analog behaviour of electricity started impacting digital systems, more brilliance was needed. Op-amps are a comparable marvel of simplification in analog electronics. They're very easy to use, but not at all easy to design. (And again, high speed causes big problems.) In mechanical clocks, the basic design of the escapement doesn't vary much. Like digital electronics, it reduces a lot of variables to a series of discrete steps. However, I'm sure the design of an escapement must balance a lot of hidden issues.

    • I was wondering this too and looked it up: "At the Paris Observatoire a high-standard astronomical regulator clock was kept running on correct mean time by astronomical transit observations, being corrected daily. Pulses of electricity were sent every second to secondary clocks around the city, the wires being run through ducts in the sewers. Two loops starting and ending at the Observatoire carried thirteen clocks between them, the farthest being at a distance of seven and a half kilometres, or nearly four and a half miles from the observatory. The clocks were of a high standard, so they could keep good time even if the synchronising pulses failed. (The pulses synchronised the clocks but did not drive them, they were weight-driven in the conventional way) The secondary clocks were furnished with second-hands, and were placed so that they could be easily seen from the street, usually in prominent positions. They further distributed time by sending electric signals once an hour to synchronise various public clocks. The system came into operation in 1878." So it appears that electronic synchronization was in use at this time but just not cost effective at the level for mass production. However, having a few extremely well made electronic clocks was worth the cost.

    • No, you don't need a "more powerful air burst". Since its a sealed, enclosed system, it just meant, you needed a longer airburst. The airburst of 20 seconds were enough to move all clocks on each "branch". When all clocks on a branch were "full", the system would just build pressure without using it, and release the pressure out of some safety valve or similiar. Think like this, you put 1 baloon on a air compressor. It takes pretty quick to blow it up. Repeat same thing with 100 baloons. You would still be able to blow it up, it would just take 100x longer time. You don't need more pressure or more power for that. So as long as each branch were limited to a specific number of clocks, it would work fine. Note how there was a large pipe connecting to several smaller pipes, this ensured so each branch shared the same air amounts. Yes, if one branch got 1 clock too much, it would "steal" air from another branch eventually, so there was a upper limit how many clocks the whole network took. Thats why it was connected to a fee, because if too many clocks were connected, no clocks would work. So they needed to limit adoption, thats why there was a fee. If too many users would still join the system, they would need to elongate the time the system worked by increase the area of the airbrake so the valve would remain open for a longer time than 20 seconds. But they couldn't enlongate the airbrake previously, because if the system closed the valve too late, there was too few clocks to release air pressure quickly enough to ensure it was ready for another minute when the next pressure wave came. So the pressure advancer would be in a "open position" all the time. Thats why the airbrake needed to be adopted for the number of clocks on system, so if too few clocks were active, they would need a shorter open time, and if too many clocks are there, they would need to elongate the open time.

    • @@sebastiannielsen Another source mentions that they later expanded to a second facility for greater pressure generation, so presumably if this had caught on in a big way they would have ended up with air stations dotted all over the place operating relatively few clocks per unit. Perhaps the substations would even be synchronized to a higher master clock in the same manner.

Think like this: Connecting a wheelnut gun requiring 5 bar to a compressor. If you connect 10 such guns, you dont need more pressure - its not like you need 50 bar. You however need much more liters per second at 5 bar.

    • There is theoretically no pressure drop since it was a closed system. Leaks were inevitable, however as long as they were kept to less than the amount necessary to pressurize the system for each pulse, they had no effect. The leak would be detected by the clocks that appeared out of sync.

  • This is excellent, thank you. I absolutely love clocks of all sizes. At college in Southern Ohio, I weasled myself in charge of the so-called South Green Tower Clock, which had 4 faces and each hour hand was 7 feet long. It was all electric, but I lubricated things, re-sync'ed with the WWV radio signal, and changed out the clockface lightbulbs. It also had an amplified bell toll (Westminster Quarters) that I programmed to play between noon and 9PM because no one in college wants to be woken before the crack of noon. I've also built Regulator-style clocks and worked on in-building master clocks. Just fascinated with clocks. I was scratching my head on this pneumatic system because of the lag. But, if you think about it, all of the clocks will be in the same minute within the minute. Back then seconds were unnecessary. :)
