The problem is not density but collection surface area. The most efficient solar system is not photovoltaic cell but concave mirror for hot water boiling. Sometimes, change the definition of the problem does not make the "real" problem go away. We will just say "neat!" and move on the tackle the real hard issue of cost and solar collection surface area.

Yes. I agree, that concave mirror for hot water boiling is the most effective way.
Actually that way is also transform the problem .
