A screw conveyor is a machine that uses rotating helical screw blades called "flighting" affixed to a central shaft and supported at either end by bearings. The Archimedes screw is commonly used to safely move fish out of tanks for processing (The Pescalator is an example of the Archimedes screw being used for this purpose). Archimedes screws are also used for materials such as powders and grains. Compared to other low head turbines, such as the Kaplan, the hydrodynamic screw is technically very simple with significantly lower installation and operational costs. Archimedean screws are an old idea (attributed to Archimedes of Syracuse in the 3rd Century BC), but until recently – within the past 10 years, they have always been used to pump water uphill. The screw is connected to a gearbox, to step up the rotational speed, which is in turn connected to a generator which maximizes the torque of the screw to produce power. On setting it up at an angle with the water level and turning the shaft manually or by a windmill, the water raises up the helical structure of the screw … • as a stand alone power generator in remote locations. • to provide safe fish/eel passage while generating power on existing large scale hydro electric dams. there are some marks and scuffs, but overall these are in very good condition for their age.
