🌾 Steppe Windmill: Sails, Wind Power, Gearing and Millstones

A wooden Ukrainian-steppe post mill (vitryak) in 3D: a blade-element model of its twisted lattice sails, the Betz limit, the brake wheel and stone nut gearing, and the stones that turn wind into flour. Turn the mill into the wind, reef the canvas for a gale and find the best sail pitch.
