My point was that if pollution is a concern, researching Mining productivity 2 or higher is a relatively long term answer: yes, better than productivity modules but (due to the resource cost) still a bad idea in the short term. On the other hand, if pollution is not a concern, it isn't a "significant drawback" of modules.mmmPI wrote: Mon Oct 10, 2022 5:25 pmIt would create even more pollution if one had placed PM3 in its mining drill while doing the research !SoShootMe wrote: Mon Oct 10, 2022 5:09 pmTrue, but producing the science packs in order to research mining productivity bonus also creates (quite a lot of) pollution, and after Mining productivity 1 they are fairly/very expensive technologies.mmmPI wrote: Mon Oct 10, 2022 3:18 pm Another significant drawback of the prod modules in mining drill is that it increase the pollution per ore by a lot contrary to the mining productivity research.
The (one off) resource cost and (ongoing) increased power of productivity modules are separate concerns and I think pollution is very minor compared to these. For example, as you described, you can't create many Productivity module 3s for the total resource cost of researching Mining productivity 1-3; far fewer than you would need to fill a reasonable number of electric mining drills to get the same +30% productivity.
