A user spent an afternoon with Claude Opus 5.5 working out exactly how a water mill runs: water fills buckets to drive the wheel, gears step rotation from 6 rpm to 120 rpm, and the millstone grinds grain—with the whole mechanism actually running. Efficiency sits at 46%, approaching the 60–80% of real water mills.
