Abstract

A solar energy generator comprises a system (10) for concentrating solar rays (R), means (12) for absorbing and accumulating the heat of the solar rays concentrated by the concentrating system (10), and a heat utilization plant (14) operatively connected to the absorbing and accumulating means (12). The absorbing and accumulating means (12) comprise a hollow body (20) with a chamber (22) which is substantially isothermal at high temperature (greater than about 800 "C) and which is utilized in a high-efficiency thermodynamic cycle, for example, a gas cycle of the gas turbine type or a steam cycle for the generation of electricity with zero emissions. The hollow body (20) houses a plurality of capsules (30) containing a two-phase material or compound with a phase transition temperature substantially in the region of the range of temperatures that can be reached inside the chamber (22). The solar-ray concentrating system (10) comprises a plurality of concentrating mirrors (16) and collimating mirrors (18) with two stages so as to reflect the radiation towards the absorption and accumulation means (12).
