Whats a good power source to run a mass fabricator. I would say that im in a medium stage of the game, not too advance, but working my way up there, i have about 64 solar panels that are providing more than enough power to power 10 machines, so i have made a MFSU to store the extra EU. But its still not going to power a machine that needs 1m EU to make 1 uu matter, any ideas?
