Archimedes Screw | Tethys Engineering

A helical surface surrounding a ventral cylindrical shaft. Historically designed to efficiently transfer water up a tube, an Archimedes screw is a helical surface surrounding a ventral cylindrical shaft. Energy is generated as water flow moves up the spiral and rotates the device. The slow rotation implies coupling to a generator through a gearbox.

Archimedes' screw - Wikipedia

An Archimedes' screw, also known as the water screw, screw pump or Egyptian screw, is a machine used for transferring water from a low-lying body of water into irrigation ditches. Water is pumped by turning a screw-shaped surface inside a pipe. It is named after Greek philosopher Archimedes who first described it around 234 BC, although there is evidence that the device had been used in ...

Build an Archimedes Screw | STEM Activity

The Archimedes screw was invented by Archimedes, an ancient Greek scientist. It was originally used to pump water out of the hull of a large ship to prevent it from sinking. Eventually its use expanded to other applications, like moving water from low-lying bodies of water to higher irrigation ditches, or moving other liquids like chocolate!
