A modified Brayton Cycle Engine employs solar radiation to heat a compressible Brayton working fluid for driving a turbine to which an electric generator is coupled for converting solar radiation to electricity. A compressor, also coupled to the turbine, compresses the Brayton working fluid before it is heated by the solar radiation. Heat from a solar MHD generator may also be used to heat the Brayton working fluid. A heat pipe can be used to efficiently transfer heat from the solar radiation or MHD generator to the Brayton working fluid. Spent Brayton working fluid exiting the turbine is passed through a heat exchanger to preheat compressed Brayton working fluid exiting the compressor before the compressed Brayton working fluid is heated by the solar radiation. The spent Brayton working fluid exiting the heat exchanger may be further cooled in another heat exchanger across which ambient air can be blown.
