I just had another idea for a use for Iridium...
A TIME MACHINE
Said machine could be used to speed up time (speeds up day/night cycle, machines, crop growth, .ect) This machine would consume a large amount of energy (maybe as much as a Mass Fabricator without scrap) and would be crafted with say three iridium plates, an advanced machine block, and maybe a clock?
Just another idea,
