ooh, shiny. sounds like a nifty way of plugging one of the problems with modular power suits: lava protection. (a full q-suit gives you nice fire protection but wow is it expensive)
What's the energy cost going to be like? Cost per fire tick prevented or something like that?
What about instead of energy, it being instantly refilled with coolant cells or heat dissipated in a reactor (sounds silly, but it would be free and take a LONG time).
If GregTech is installed it could be cooled in the Vacuum Freezer.
Okay, i'll add that. You will be required to have a Enchanted Book of Silk Touch (or Fortune) to get the enhancement.
Add that, if it detects GregTech, it changes the recipe to require 2 RockCutters (a silktouch tool) + 2 energy flow circuits.
Also, I'm thinking of a crazy overcomplicated system of duplicating items. It will require exactly as much UU as it would if you craft it normally, but it will a bit more clever.
Maybe add something similar to EqEx EMC, however that "EMC" value is UUM dependant. Lets call it Matter Unit.
Lets say, that 16 wood has 1 MU (1 UUM). Values are based on actual UUM recipes.
If you are duplicating 64 planks, it would require 1 MU, multiplied by 1,005.
It would first detect the value of the MU of all basic components, then multiply the total value by 1,005 for every crafting step required, 1,01 for every processing required (macerator, extractor, any other kind of machine), 1,05 for centrifuge/electrolyzer recipes (GregTech). If it can't UUM certain components, it will request them. [For example if you need certus quartz (dust) for AE stuff]
Those multipliers stacks, so if something requires, for example, 10 craftings and 20 processings, it would cost :
All raw components MU values * 1,005^10 * 1,05^20 = 1,22019... (1,22) MU of all raw components.
That would make complicated items considerably expensive to duplicate.
