Fluid-driven “gears” could out-perform mechanical devices

US researchers have created a gear mechanism that uses fluids, rather than mechanical teeth, to generate rotation. They ...

Liquid gears could challenge 5,000 years of mechanical engineering

The study, published January 13 in Physical Review Letters, replaces the metal or plastic cogs of conventional gears with controlled flows of liquid. In their experiments, ...
