Brilliant, I'm surprised I haven’t heard of this before.<br>Would this work just as well with liquids as does the original Archimedes screw!,(reply>), It is brilliant for vertical(!) elevation of granular material, from powders through to even ground-up glass.  Archimedes is fine for horizontal or shallow inclines. With a big screw to casing gap for liquids to flow around, it is not meant for water etc .  Granular materials do great.
