Essentia tubes feel like there's some secret holding the system back. That discovering it would open up millions of possibilities, but sadly that epiphany doesn't happen.
Also while essentia buffers let you fill up the jars they tend to have trouble with the thaumatorium and other requesting machines. They tend to block the suction and not feed in to thaumatoriums directly, at least in my limited testing.
People want their rows of jars to be on demand for alchemy.
I think Azanor or someone else needs to document the mechanics of essentia tubes more elaborately. Because all I know about them is that certain items produce suction of a type or untyped. To get essentia to travel you need to make sure the sources suction is the same type as the destination but be a lower value.
In the case of a thaumatorium while it requests essentia for a craft it's suction for that type goes up, if your jars have a loer suction then essentia will enter it.
Also only one type of suction can be present in a line of tubes at a time, multiple essentia sources of a different type gum up the system if one type of suction isn't cleared.
Essentia tubes mechanics are quite vauge.
