if one was able to make a perfect concave mirror with half a cube shape perfect mirror in front of it ( so thermally isolated from outside with a perfect vacuum inside it) And a black body almost covering the front of the Concave mirror that is red hot and another much smaller black body in the focal point of the perfect concave mirror ( perhaps white hot) could one take the higher temperature heat from the white hot body and put it through a heat engine with the red hot black body been used as the cold sink (heat needs to be added at the red body temperature) So the heat rejected by the heat engine is not lost but recycled by been concentrated by the concave mirror and reused. Could a system of higher than cannot efficiency be created?
