Surprising that anyone still thinks the Penrose model could work. Microtubules do not exhibit harmonic motion like violin strings. The reason is that all motion at the length scale of cells or smaller is heavily overdamped.

The environment within a cell is nonintuitive. To find out more about this, read “Life at low Reynolds number” or “Mechanics of Motor Proteins and the Cytoskeleton” by Joe Howard.
