1. A solar receiver for a concentrated solar power station operating at light concentration values of up to 20,000, the solar receiver comprising:
a heat-absorbing solid body comprising a material with a melting point in excess of 1500° C., wherein the heat-absorbing solid body is a rotor and is frustoconical in shape, wherein the heat-absorbing solid body is hollow with an open end and an interior of the heat-absorbing solid body that is defined by an inner surface of the heat-absorbing solid body that is a truncated cone and faces the interior;
a light focuser having a structure to focus light through the open end of the heat-absorbing solid body and onto the inner surface of the heat-absorbing solid body; and
a heat exchanger cowl arranged to provide a flow of working fluid over the heat-absorbing solid body;
wherein the light from the light focuser impinges over time on portions of the inner surface of the heat-absorbing solid body and heats the heat-absorbing solid body which in turn heats the working fluid proximate to the heat-absorbing solid body; and
wherein the heat-absorbing solid body is movable relative to the heat exchanger cowl, wherein the inner surface of the heat-absorbing solid body rotates about an axis, and, after one revolution of the inner surface about the axis, the portions of the inner surface define a continuous portion that surrounds the axis and is exposed to the light.
