chemical potential as noted above fig4 a 4f depict the exemplary motion of the focus element actuation system 3 as the solar power generation device 100 transitions from the inactive or closed state to the active or open state when the solar power generation device 100 becomes active the restriction ring 19 is allowed to drop as the restriction ring 19 drops the potential gravititional energy is converted into electrical energy that is transmitted to the sensing system 9 and the tracking system 2 for example the restriction ring 19 may spin an electric motor which in turn creates electrical energy for the other systems energy may also be transferred back into the mechanism for raising and lowering the restriction ring 19 when the restriction ring 19 reaches its final position the focusing elements 6 are fully deployed and the solar power generation device 100 enters the active state when entering the inactive state the solar power generation device 100 may perform a similar process as opening however the steps are performed in reverse the restriction ring 19 may rise thus closing the deployed focusing elements 6 once the focusing elements 6 are fully close the solar power generation device 100 may enter the inactive state a manual override not.
