Tornado had to spin the moonrocks upward so that it could load up. Then it would release them in the other direction.

Attached are two CAD picks of 148s Archimedes screw from 2009. (Hid certain components to make it easier to view center.)

To answer your question of how they worked. You would have a center axis that would rotate 360 degrees. Attached to the center axis would either be fingers or brushes to move the balls towards the top. The spiral would raise in a clockwise fashion and the brushes/fingers would spin in the same direction.


Here are some other Archimedes screws from 2006/2009
1100-2009
233-2006
1771-2009

I agree with Martin. I don't think a screw is completely necessary as you can only possess 3 balls at a time.
