If I do want to give my Empire a nice boost, I would much rather build Atmospher Converters, as the effect of these facilities is much more marked. But obviously, it is only if I am patient enough to wait for thirty turns before the atmosphere is changed.

I was playing yesterday, and it seemed to me that on some planets I had 2 atmosphere converters, and they were converted faster than other planets. Is this true? Can multiple converters and climate control facilities on one planet produce results quicker?
