| Abstract: | The overall efficiency of a system including a solar paraboloidal concentrator augmented by a new type of nonimaging second stage concentrator (shaped like the bell of a trumpet) and coupled to a heat engine is investigated. Typically, a relative increase of 10 per cent in system efficiency was found due to the second stage. |
