200 B.C.E. , which when twisted inside a cylinder, raises water from a lower level to a higher level, allowing irrigation of fields. The Archimedes Screw is an invention that revolutionized irrigation and water removal. It was invented by Archimedes in the third century B.C. The device was made up of a large screw enclosed in a cylindrical pipe. It is set at about a 45 degree angle. Further, archimedes screw come in different types, based on where they are to be used or planted. archimedes screw have high power supply capacities.
