Feature to use 9 full stacks of items in the crafting grid allows you to use more compact recipes, like:
x64 x64 x64
x64 x64 x64
x64 x64 x64
= x1 item
I disagree with the recipes above. I'm believing into uselessness of these recipes, since the balance of this game is completely different than minecraft. Also this topic most suitable for Mod Development category, because the developers didn't say what they were planning electricity.
Btw, I'm reading a lot about the production of aluminum now, this is a very complex process (Bayer process + Hall–Héroult process), because even for such a simple thing, you need to add a lot of multiblocks, which sooner or later will definitely should to be added (I'm only talking about a hypothetical tech mod). For example, an electrolyzer is a useful thing even without aluminum. Luckily, all the necessary materials are already in the game (but there is no ore for soda etc., some materials could be gained through "ore washing machine" or in a more immersive way with more chemical formulas and mooore multiblocks)
