I just realized that this is a mirror plant, not one with acres of actual solar cells. I don’t think this design uses acres of toxic coatings.
OH! On further review, you are right; so this is one of those with boilers on towers.
So, they have to supplement output by using natural gas? Guffaw. I wonder if that is so they can have output at night? That is the inherent weakness of solar/wind juice; sometimes, like once a day, hours at a time, the natural source doesn’t cooperate.
