I'd like to see how an aluminum can could be crushed into a sphere/ball of the smallest volume. Seems it would be a space saver for recycling, make it easier to melt down, an possibly provide other uses? I was thinking maybe cylinder comprised of lobes that rotate to reduce diameter, then cup shaped piston pushing into cup shaped anvil.
Not sure how to incorporate auto-feed, or discharge, and all in the simplest means, possibly using things that don't have to be fabricated.??
