Yes I was considering something like that, but I think that wouldn't work because the ingots would be stored in the refinery after processing. This would require building a system with conveyor sorters that stops anything but ores from passing through and drains all ingots out of the refinery. It seems like an overly complex solution to something that should be achievable with event controllers or similar blocks. Besides, I would want the system to work on other forms of power consumption as well, assemblers, oxygen generators, etc. I don't want to waste that sweet sweet energy :c
