Possibly the most important industrial tools we would need is cutting tools. That's not kitchen knives. Those are easy. It's drill bits and lathe cutter heads. That type of steel can't be made with a water wheel and burning biomass.
High quality steel that can't be made in those conditions is also needed for rail tracks.
- dredmorbius 2y agoCanals are a reasonable substitute for railways in many cases. They're slower, yes, but can move far more goods at scale, and with only modest power inputs. In colder climates (should such exist), they also become ice highways in winter time, which permit for year-round bulk transport. Though the elevation gain/loss features of canal locks are lost in the latter case.
