Huh. I thought planets on repeat orders only went through their orders once each turn. It turns out that planets execute exactly 21 orders each turn, going through the list multiple times if it's shorter than that and on repeat. So, to do a resource conversion once per turn, put some units on the planet (troops will do), give the conversion order, fill out the queue to 21 orders with unit launches (any type, regardless of what's actually on the planet), and turn on repeat.

As for the storm creator, I tried that in a test game a while back with the latest patch, and it didn't work. Maybe it's because storm creators are destroyed on use now and weren't earlier (I don't know whether that was changed in a patch or not), but it's not a problem in stock any more.
