http://www.epicphysics.com/ An animation showing the screw pump designed by Archimedes of Syracuse. The Archimedes screw was designed to lift water from low lying areas to higher areas for irrigation purposes. Archimedes screw can also be found in today's machines, from industrial manufacturing plants right down to miniature pumps in modern engines.
