Elon Musk revives his plan to power the United States entirely on solar: “All you need is a 100 by 100 mile patch in a deserted corner of Arizona, Texas or Utah (or anywhere) to more than power the entire USA.”

Well, Musk could put a huge parabolic mirror in orbit and always have the sun shining, 24/7, on the panels. It isn't entirely impossible at this point. It would also burn through any cloud cover. The only thing that would prevent this from working would be dust clouds, such as from volcano eruptions, or nuclear ashes.

Then you wouldn't need backups!

But then again, if your array is 100mi x 100mi, the mirror would have to be what, 400mi x 400mi? Even multiple ones would have to be incredibly huge.

Indeed.

For my /s/BittersweetSeeds project (barely started but will is my New Years resolution, and I rarely bother with resolutions) I was trying to conceptualize the industrialization of space and power. I had soooo many ideas, including giant mirrors, conversions, Microwave transmissions, etc etc etc. As I researched I realized many things were scientifically impossible, some pure fantasy, and many things were incredibly impractical at any scale. My process was to come up with ideas and determine how they wouldn't work, then build work arounds. And repeat. If I couldn't build a work around, then it would not be valid. The same is true for the related political and economic stuff.

Further, there are countless problems with the current efforts with space, including the re-usability, space debris, etc.

None of this is really touched on much until Act 3.
