I was poking through the roadmap and saw this:

"Some way of extracting fuel from Thaumcraft nodes?"

Perhaps if you can use Venenum, Metallum, Potentia, and Praecantitio essence in some kind of machine to produce Yellorium? Or piping them in directly to an individual reactor, like you do Steam into the Turbine. Turning a Wisp/Mana Bean farm into RF this way would be awesome.

Could you post some pseudo code? This would be cool to add.

I think lore wise it would look like this:
Radioactivity has similar properties to flux (the letter is far waker tough). If you handle vis incorrectly, flux is being made.
