A similar recent invention is the Olds Elevator: https://youtu.be/-fu03F-Iah8 https://youtu.be/-fu03F-Iah8

  That's wild. I'm still a bit unclear as to the advantage it has over rotating the screw, though? The inventor mentioned less dust and wider tolerances, but why?

    The material completely fills the tube, so there's no space for dust.

    At the bottom the tube has scoopers to bring the grain inside and those need to move trough the grain. If you keep the tube static the grain would need to go inside by gravity alone and I guess that does not work as well
