Uses
Along with transferring water to irrigation ditches, the device was also used for draining land that was underneath the sea in the Netherlands and other places in the creation of polders. A part of the sea would be enclosed and the water would be pumped out of the enclosed area, starting the process of draining the land for use in agriculture. Depending on the length and diameter of the screws, more than one machine could be used successively to lift the same water.
An Archimedes' screw was used by British soils engineer John Burland in the successful 2001 stabilization of the Leaning Tower of Pisa. Small amounts of subsoil saturated by groundwater were removed from far below the north side of the Tower, and the weight of the tower itself corrected the lean.
Archimedes' screws are used in sewage treatment plants because they cope well with varying rates of flow and with suspended solids. An auger in a snow blower or grain elevator is essentially an Archimedes' screw.
The principle is also found in pescalators, which are Archimedes screws designed to lift fish safely from ponds and transport them to another location. This technology is used primarily at fish hatcheries, where it is desirable to minimize the physical handling of fish.
It is also used in chocolate fountains.
In 2012, Jakub Halik, a Czech Man, lived for six months with an artificial heart designed based on Archimedes' screw by Dr. Bud Frazier and Dr. William Cohn from the University of Houston Medical Center.
