Probably not original, but I'm surprised more solar implementations don't use a simple passive fresnel lens for a concentrator. Seems like a no-brainer for solar-thermal, and possibly a good idea for PV too, as long as the PV units are capable of handling the extra heat and energy; but I know nothing about PV tech.
