Self-Sufficient Stabilized Carbon 60/min

Zero-input charcoal production line. 3 sandleaf farms, 2 carbon lines, and no bus space consumed, outputting enough charcoal to fully utilize one Forge of the Sky. Put one or two of these anywhere, and then you can place your Forge(s) near any convenient water supply. Or, replace the stash with a Forge and place the whole thing oriented to the wet side of your factory site.
