The Archimedes Screw has been used in the past as a means of drawing water at low level to a higher level. Its design has been attributed by some experts to the ancient Greek scientist Archimedes.

The earliest pumps were devices for raising water, such as the Persian and Roman waterwheels and the more sophisticated Archimedes screw. The mining 

A positive-displacement pump traps fluid from a source and then forces the fluid to move to a discharge location. Most Archimedean screws have three flights, or three separate helices winding around the central core. Archimedean screws typically rotate at around 26 rpm, so the top of the screw connects to a gearbox to increase the rotational speed to between 750 and 1500 rpm to make it compatible with standard generators. PDF | On Jun 1, 2013, Dirk Nuernbergk published The Archimedes Screw: Lessons in Calculus - Volume Calculations | Find, read and cite all the research you need on ResearchGate Archimedes screw systems are run of river systems and therefore the timing and variation of water flows is unaffected. Archimedes screw systems do not attempt to “store up” water in a reservoir. Archimedes screw systems produce hydropower cost effectively.

ASCE Journal of Hydraulic Engineering Volume 126, Number 1, January 2000, pp. 72-80 THE TURN OF THE SCREW: OPTIMAL DESIGN OF AN ARCHIMEDES SCREW. By Chris Rorres ABSTRACT: The geometry of an Archimedes screw is governed by certain external parameters (its outer radius, length, and slope) and certain internal parameters (its inner radius, number of blades, and the pitch of the blades).

The Archimedes screw has been for pumping water millennia. Archimedes screws driven by wind mills were one of the primary means of dewatering the low-lying polders in the Netherlands until the advent of practical fossil-fuel driven pumps. Variations on the Archimedes screw are also found in Archimedes, the most famous mathematician and inventor in ancient Greece.
