Method and system for converting solar energy into electricity

Abstract

There is provided a method and a system for converting solar energy into electricity by means of a magnetohydrodynamic (MHD) generator. The method comprises providing an organic liquid reservoir having an ejector nozzle positioned at the inlet port of a MHD generator, providing a liquid alloy reservoir in fluid communication with said inlet port, and heating said organic liquid to its boiling temperature by means of solar energy absorbers so as to form high pressure vapors of the organic liquid adapted to propel the liquid alloy through said MHD-generator, whereby solar heat energy is converted into mechanical energy and said mechanical energy is converted into electrical energy in said generator. The system comprises an organic liquid reservoir having an ejector nozzle positioned at the inlet port of said MHD-generator, a liquid alloy reservoir in fluid communication with said inlet port, a solar energy absorber adapted to heat said organic liquid to a boiling temperature to form vapors adapted to be emitted from said nozzle and to propel the liquid alloy through the MHD-generator wherein solar energy is converted into mechanical energy and mechanical energy is converted into electrical energy.
