Q: How do I get Ferrous Ingots or Ferrous Ore? I need them for Invar Ingots. DW20.
They are underground, diamond or gold level IIRC but not very often. If you have map from 1.4.2 they may be not generated, but you probably just didn't find any because they are quite rare
Also using TE's pulverizer, when pulverizing iron, you will occasionally get a ferrous dust.
I see; but what about the over flow problem? An wouldn't it be more efficient to use charcoal, because if it takes even 3 or 4 wood to match one charcoal, and you out all that in to a furnace and you get 200 smelts or whatever out of it, then yes in the long run it's more power but you'd still have to replace the fuel supply more often to compensate for the rapid deterioration of the planks.
Sawmill makes 6 planks per log. .3k heat per plank, or 1.8k heat per log. Charcoal is 1.6k heat per piece. Planks make more steam per log than charcoal, when sawmilled. Plus the sawmill also makes sawdust, 8 sawdust=1charcoal. The sawmill only takes 2mj/t, a 36HP boiler makes 144mj/t. So a Steve's Cart tree farm+sawmill+36HP boiler=142mj/t-any loss from golden pipes, redstone conduits, etc. Over flow can be handled easily. Sawmills output directly into a chest. Boilers can pull fuel directly from a chest. So put a chest next to your sawmill, chest next to your boiler, BC pipes, RP tubes, or golems keep the boiler chest stocked from the sawmill chest.
If your making way too many planks, either set up another boiler or 2, or scale back your tree farm. Want even more energy? Turn all the extra saplings you'll get into bio-fuel and crank up another boiler or 2. Squeeze apples for mulch for the fermenter, and apple juice. Trees are about the most OP energy source, imo. If you do go charcoal, I'd recommend smelting it in a coke oven. Takes zero fuel and makes creosote oil, which is more energy. Coke ovens are dirt cheap, all you need is bricks and sand.
Oh yea, I had a question too. BT battery boxes, which side do empty BT batteries go in and which side do full ones come out? And vice-versa, to keep a remote battery box full, which side do charged batteries go in and empties come out? I'm wanting to transfer BT juice from solar panels to bedrock level with enderchests and BT batteries.
