The development and use of an indoor solar cooking system powered by solar thermal energy is described. The system uses a concentrating evacuated tubular collector to supply thermal energy to a high temperature cooking surface so that heat can be used for cooking in day time. The system incorporates a passive downward energy transfer system between the solar collector and the cooking surface. The cooking system can be installed indoors and the collectors placed on any convenient place, without the need for pumps or thermo syphon loops to transport energy from the solar collector to the cooking surface.
