So the birdkill is actually from a separate focal spot near the absorber where standby heliostats are focused? Interesting, I did not know that! Makes me wonder why standby heliostats would need to be focused at all? Couldn't their aimpoints be randomized over a much larger volume near the receiver, while still being standby and able to quickly move back onto the receiver when needed?

By the way, I’m happy to find someone with CSP knowledge on HN. Are you working in the field?
