This is the part of the factory that produces Biomass. The fermenter on the right produces biomass from excess saplings from the tree farm. The 2 machine on the left are squeezers producing apple juice from apples that I collect with a forestry multiblock farm set up as an orchard. Apple juice gives a 1.5x bonus on biomass per sapling so it is worth using over water. The water pipe is an emergency is apple juice runs out. The whole thing is fed using logistics pipes connected to my unified logistics system.
Opposite the biomass production is the Biofuel production. Biomass is converted to Biofuel in the 5 Stills. The liquid fueled boilers require Biofuel instead of Biomass. This biofuel is then stored in the iron tank.
Under the floor is a mess of pipes, liquiducts and energy conduits feeding the machines. This isnt neat as nobody will see it and none of it ever needs maintenance.
This is the steves carts tree farm that provides saplings for biomass production. You might be able to tell from the shape that it used to be an old forestry arboretum.
This is the new multifarm producing apples. It also is producing rubber atm as I had a sudden shortage last night.
Here is a close up of the steam engine arrays. Nothing fancy, redstone underneath, steam on top, and energy conduit down the middle.
Here is the guts of the turtle charging station. The gates emit redstone when the adjacent energy cell is full, and the turtle acts on the colour of the redstone to know which to collect. The redstone signal also has the side effect of turning on the adjacent panel indicating it's full.
The smoke from the chimneys is indeed smoking blocks from Twilight Forest. These are hugely common in fire swamp biomes.
A couple of full base shots to finish up.
