But that engineering problem has proven remarkably difficult.  I am thinking in the short term.  next 30-50 years.  It’s nukes and coal for baseload until we can get space-based solar going, if we ever do.

What about lunar-built-and-launched solar power?  Or putting solar panels
on eternally-sunlit parts of the Moon (after having built them on the Moon,
to reduce transport costs) and beaming from there?
