I've been dragging through forum discussions quite a bit. Here's a thread that has some comprehensive notes, with links to things confirmed by Azanor and the source code: Aura and You: All About Thaumcraft 3 Aura Mechanics | Feed the Beast
Crystal clusters can recharge vis, but they do so very
slowly, and they can actually charge a node above its maximum, which is interesting, but guess what that causes?
Also, they can only be discovered through knowledge fragment research, so they're a bit of a shot in the dark.
On the other hand, Azanor has said that if you can get to 10 over the node max, a dull ore will turn back into an elemental ore, and if you can get to 100 over, it will turn a block of stone into an infused ore.
I'm doing some code diving myself to work out the flux generation. I'll report back when (if) I figure anything out.
