We consider ways of increasing efficiency of solar trough receiver pipes by decreasing the leading thermal radiation losses. We study the use of a secondary concentrator, a “solar funnel”, which reduces the area that emits thermal radiation. We further increase efficiency by use of a heat mirror on the glass cover which reflects the thermal radiation being emitted by the receiver pipe back onto itself.
