- dredmorbius 4y agoManufacturing (and installation, operations, and maintenance) efficiencies are more likely governed by Wright's Law, a/k/a Experience Curve Effects, which holds that there is about a 20% efficiency gain with each doubling of output. <https://en.wikipedia.org/wiki/Experience_curve_effects https://en.wikipedia.org/wiki/Experience_curve_effects> This was first observed during WWII in aircraft and ship manufacture. Note that this tends to be gains toward some ultimate efficiency limit, so remains bounded. I've mentioned the concept a few times in earlier HN comments: <https://hn.algolia.com/?dateRange=all&page=0&prefix=false&query=by%3Adredmorbius%20wright%27s%20law&sort=byPopularity&type=comment https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...>
