Machine · Concept M1c

Large-format solar concentrator

Same construction method as M1a (wooden frame, flat mirrors, evacuated tube, hand tools), with a receiver tube ≈3.05× longer (137×1860 mm) to melt larger volumes of plastic per cycle.

🔴 Concept not built — dimensions, weight and costs obtained by documented extrapolation from the validated M1a design, not from a physical prototype.
