    And it uses cheap and plentiful gold as the back plating to enhance reflectivity.

    Funny how that works, innit? The race to higher efficiencies and the race to more practical solutions often do not have much to do with each other.

    Well sometimes in practice once the scientists have built a very expensive Proof Of Concept, the engineers will be able to find a more economical way to get close to the same result.

    Sometimes, yes; sometimes, no. But we try. :D
