YES!!! The 'Slinky' --- as we all know --- can NOT move in 'perpetual motion' unless the STAIRCASE upon which it is set-in-motion (i.e., gravity-feed) is ALSO moving (forever) as well!!! Bottom line, EACH of the depicted 'SLINKY/STAIRCASE' units will be operating independently at EACH of the Apogee-D7's drive WHEELS!!! Simply an ASTONISHING, automotive engineering achievement!!!
