I saw this article about a “huge” solar farm in Arizona. I’ve been reading a lot of physics non-fiction and sci-fi lately, so my definition of “huge” has been expanded. All of Arizona isn’t exactly “huge” to me right now, and this solar farm would just be a glint if seen from orbit.

Just a thought, but at a certain scale, the mirrors focusing energy can’t just be placed on the surface of the earth and pointed at a tower or other collector. At “enormous” scale, because of the curvature of the earth, the mirrors will actually have to point to something under the normal continuous surface earth, or the light would have to be re-reflected along the surface (the way microwave towers do today). That would really be something to see.
