Abstract
The present invention provides improved methods, apparatus, and manufacture for an Archimedes Screw using a strake design as a blade to increase the volume of water raised or lowered by about 10%. The invention, in part, alters the shape of the blades within the screw from a helicoid shape to a strake shape. A helicoid blade in an Archimedes Screw has been used since antiquity and has not changed since then, limiting the efficiency and manufacturing process. The strake shape allows a greater quantity of water to be contained within the screw and is a developable surface that enables easier fabrication than the helicoid shape.
