I don't agree that solar is proceeding at a snail's pace anymore.
There is currently a great deal of research activity surrounding
quantum level engineering of this stuff. For example, behold
the Spinach Solar Cell:
While I am being a bit flip, there is a lot of single molecule
layer engineering going on in a lot of fields (LCD Displays, solar
cells, semiconductors, pharmaceuticals, etc). An advance in
any one of them advances all of them.

And collecting that heat requires a plumbing system which is
in a naturally corrosive environment. This is better than a
man-made reactor *how*?
