I am very happy to see your ideas on how to get rid of the tracking device.
That is the right way for constructing large solar reflectors.
Your two other ideas
(1) multiple focal points ( ripples in your words) and
(2) Multiple reflectors with parabola as the second reflector are asloworth persuing.
Can you draw a geometric construct with sun at 9 oCLOCK, 12 oCLOCK AND 2 pm?
