The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw,[1] is one of the earliest documented hydraulic machines. It was so-named after the Greek mathematician Archimedes who first described it around 234 BC, although the device had been developed in Egypt earlier in the century.[2] It is a reversible hydraulic machine that can be operated both as a pump or a power generator.
