The submerged tidal stream device can operate in low flow velocities (1 m/s) that current devices are unable to. The inclined and horizontal turbines offer …
The Archimedes' screw, also known as the water screw, screw pump, Archimedean screw, or Egyptian screw, is a machine used to pull water from a low-lying water body. Water is pumped by turning a screw-shaped surface inside a pipe. Archimedes screws are also used for materials such as powders and grains. An Archimedes Screw ( Source)

The Archimedes Screw as a generator – Technology Overview. At least 400 Archimedes screw generators (ASGs) have already been installed in Europe since 1993 (Lashofer et al., 2012) and more are under construction, however there are currently few installations outside Europe. GreenBug connected the first ASG to the North American power grid in ...
Though these differences in length-scale may appear to be small, it is crucial to consider the effects of scaling on screw generator performance. Consider how the outer diameter (the primary length-scale) of an Archimedes screw effects the mechanical power ( Ps) and frictional power loss ( PL,f) during operation.
Although the Archimedes screw was developed for pumping water from lower to higher levels, the use of this device in recent years focuses on the generation of sustainable energy.

The working model of the Archimedes wind turbine consisted of a lightweight aluminum sheet of thickness 0.91 mm for the manufacturing of the blades instead of carbon fiber. The carbon fiberglass involved the casting processes that brought detour in fabrication and it raises the total cost.
Archimedes screw turbines are classified as small (1–10 MW) or mini (<1 MW) hydropower plants and are typically used at sites with a total elevation difference of 8–10 m and for discharges of 1–10 m 3 /s (Quaranta and Revelli 2018 ). The screws rotate around an inclined axis ranging from 22° to 35° from the horizontal.
