The Calefactor has 3 numbers when I hover over it with the curser. red/white/blue, the blue number increases with as it gets Neutral power. the book also says that you can have a chance to double ores if you have all three powering it. so it can accept all three power. the prism does not have a gui so I cannot put power into it. it gets power passively and shows 2500 power. what I cannot do is get that power out of it. it won't connect to the calefactor like the neutral obilisk does.
Is Crystal Wrench top purple? If it is green, it has fixed source destination, you can switch it off by shift-clicking on some vanilla block.
Also, you will probably want to put mana battteries (one per mana type) and power consumers through them. Light and dark "obelisks" have ridiculously small internal capacity.
Calefactors do accept all three power types, but I haven't noticed them doubling ores. But they do double food.
