Cube-Root-of-Two Gears by OSKAR

Hi iMaterialise fans,

Cube-Root-of-Two Gears is a gearing system that features a cascade of three Cbrt(2)-to-one gearing ratios, resulting in a two-to-one overall gearing ratio. How can that be? The cube root of two is an irrational number, whereas gear ratios are supposed to be rational. What is happening here?
