f/2.8; iso/200; 1/20s; 28mm

The Archimedes screw is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. It was one of several inventions and discoveries traditionally attributed to Archimedes in the 3rd century BC.

The Archimedes’ Screw consists of a screw inside a hollow pipe. The screw is turned usually by a windmill or by manual labour. As the bottom end of the tube turns, it scoops up a volume of water. This amount of water will slide up in the spiral tube as the shaft is turned, until it finally pours out from the top of the tube and feeds the irrigation systems. It was mostly used for draining water out of mines.
