TL;DR

NYU researchers demonstrated a completely fluid-driven, contactless gearbox by placing two cylinders in a viscous glycerol-water mix; depending on spacing, the rotating liquid generated either opposing or same-direction motion, offering a wear-free, jam-resistant method that could revolutionize gear design and enable tunable ratios for soft robotics and distributed actuation.
