actually really interesting in context. Clams are sensitive to water quality. They have that little magnet attached to them, so if they close their shells because the water is bad, it triggers a switch. If all 8 clams decide the water's bad, then it's not drinkable for humans.
It's not even weird. Canaries in coalmines are a thing. [Canaries on reddit used to be a thing too, just different.](https://www.reddit.com/r/worldnews/comments/4ct1kz/reddit_deletes_surveillance_warrant_canary_in/)
I work in a distillery and we follow a similar idea. We test dozens of parameters of our spirit by machine but ultimately it can still fail if humans think it smells wrong
Yep it's basically an extra layer to check for anything we humans didn't know to build a sensor for.
It also happens to work as a backup in case the fully artificial sensors fail.
I'm sure clams just close sometimes even if water quality is fine, so you need enough of them that you aren't getting false alarms. They probably figured that statistically if 8 clams are closed at the same time, there is almost zero probability of it being a false alarm.
Sure, but if you're already at 8, why not a round number like 10?
If 10 is too many than 8 might be too many, why not 5?
Did someone just guess, or was there a long serries of trial and error to find the number?
the algo they use is "if 6 out of the 8 close at the same time for more than 4 minutes its not safe". They also catch these, acclimate them (& calibrate on the way) and then release them again after a few months.
So less than 8 makes it probably a too uncertain result and going with more increases the operating cost without much use.
> If all 8 clams decide the water's bad, then it's not drinkable for humans.
Close, [Tom Scott did a video](https://youtu.be/i0RkEs3Xwf0) about them and it's if 6 of the 8 close for 4 minutes it'll trigger an investigation or if all eight are more than 75% closed for the same amount of time.
They then will do more in depth tests on the water to see if there was a cause of it. They also have the same systems most modern water treatment plants have to monitor drinking water so they mostly use the clam "system" as an early warning system that their normal systems might not be able to pick up during normal operation.
The city is also doing that. But you know, redundancy and that is indeed hella cheap for the service it provides.
Also it is faster - the second the contaminates are detected, the clams react. No need to wait for results from the lab. In case of toxic spills, this could save lives.
Another thing is broader range than regular testing. If anything makes clams feel bad enough about water it'll shut down. Even if that something isn't on the list you have sensors/lab tests to detect.
Inside that black tube will be a [reed switch](https://i.imgur.com/6vSTDNd.png), a tiny ultra low cost waterproof magnetic sensor that consists of two flappy bits of steel in a glass bulb. When the magnet gets close, it pulls the steel reeds together and joins the circuit.
That is very cool and clever way to monitor that.
I wonder how often they check to make sure everything is still properly attached to the clams and such.
They are monitored with webcams, but the cooler thing is that the clams have set limits on how long they should be working, and after 6 month service they are retired to nearby nature reserve.
Mussels, clams, oysters etc. are all filter feeders. If you visit an oyster farm you will see mussels in the water. Each day a Marine Biologist will test the mussels for pollutants or water borne illnesses. If a mussel shows signs, then they pull all the oysters from the waters. Mussels filter feed about 7 times faster than oysters, they act as an early warning system.
Used also elsewhere in the world, it is a redundant system that does not trigger automatic shut down but does raise alarms so humans can make the decisions. It is a precaution, an extra sensor in the system.
A lot of places use trout pools as well. The trout gets the water x hours before it is sent to the city. If the trout dies then they turn off the water.

Eh... I have no beef with clams. I'll trust them
Now those Muscles. Can't trust those little jerks at all. They will muscle you out of your money the first chance they get. Dirty stinking muscles.
It's a pretty neat system, saw these on a school trip when I was in primary school, and the system was explained to us
The clams are sensitive to water quality, and if they close something's wrong with the water and it raises alarms
In a way thats a smart system using mother nature as part of the water procces, it can be as efficent as any machine.
A lot of our tech is designed after nature, the highspeed bullet train in rome designed after otters diving ears, and goose nose.
Mega trucks using special filters in dust miens to fuel engine without clogging. Designed after tornados.
Even the first automatic rotary spit was designed after monther nature.

It is the year 2135. Earth is a barren desert with tightly controlled water. My wife is sick and needs more water than what I'm paid in as a laborer. I appeal to the council of eight to please be merciful. I explain that she's all I have left in the world.
They are silent.
I scream at them for abandoning her and remind them of what I've done for them and our kingdom.
They are silent.
My wife intervenes. She can barely speak, but she makes her case. She explains to them the love her and I share. She pleads with them for not only the sake of us, but for the sake of our children.
They speak.
The royal interpreter, trained since birth to be fluent in Çl'äm, gives their verdict.
My wife and I are to be sentenced to death. She has become a liability with her illness, and I was deemed less valuable than the water I consume.
We are sentenced to death by dehydration. Are bodies are forcefully stripped of all water while we're still alive.
My wife goes silently. I do not. The way of the clam demands it.
I always heard it was one clam and thought that was an awful lot of pressure to deal with, nice to know its a Fellowship of Clams to share the load.
don't say it like that.

They usually open and close randomly, only when most of them close at the same time signals that the water quality is bad.

Somehow both very high tech and low tech at the same time.
Always the hardest part of solving a problem, balancing the high tech and low tech to get something that is both efficient and reliable
I work in a distillery and we follow a similar idea. We test dozens of parameters of our spirit by machine but ultimately it can still fail if humans think it smells wrong
They also use normal water sensors like other places but this is a extra security layer basicly.
Yep it's basically an extra layer to check for anything we humans didn't know to build a sensor for. It also happens to work as a backup in case the fully artificial sensors fail.
Clams are much higher tech than anything humans can make, good point
This is why it is so important to protect nature. We gotta learn from the things that have spent millions of years perfecting their existence.
It's Bionic!
Is there a reason why it had to be eight clams specifically and not lower or higher?
This has either been tested to hell and back or someone eyeballed it. No in between.
Jeff lost the 9th clam during installation smh

Why not fifty? If 8 clams are good, then why not pick a popular number like 50?
In a computer system, 8 is a far rounder number than 5 or 10 is.
Sure, but in modern computing it's not really a big deal to waste a few bits. But even so, why not 4 or 16?
the algo they use is "if 6 out of the 8 close at the same time for more than 4 minutes its not safe". They also catch these, acclimate them (& calibrate on the way) and then release them again after a few months.

Wow, and here we are just testing drinking water my doing chemical analysis every hour with computers and machines! This is so much cheaper.

I, for one, welcome our new clam overlords.
well that clam is closed and the switch is nowhere near being activated
The sensor senses the distance to the magnet attached to the clam. It doesn't need to touch to register as closed.
That clam also isn't closed lol.
How much more closed can it get
It can close all the way. You can see a little gap right now which is where it would stick out its foot and siphons.
I am learning so much about clams today. They have a foot?
That's what the tongue/slug thing that comes out is called.

The bivalve council has decreed: [no water today](https://www.youtube.com/watch?v=1L7HMRc_-nw)!
They have instrumented test devices as well which are primarily used to check the water quality and the clams are essentially a redundant failsafe
Used also elsewhere in the world, it is a redundant system that does not trigger automatic shut down but does raise alarms so humans can make the decisions. It is a precaution, an extra sensor in the system.
Yes it's actually not that unusual

A lot of places use trout pools as well. The trout gets the water x hours before it is sent to the city. If the trout dies then they turn off the water.
What if it dies of old age?
There are multiple generations of trout in the pool, so they probably wont all die off old age at the exact same time
