Abstract: A solar receiver for converting solar radiation into thermal energy. The solar receiver includes a heat-absorbing solid body, a fluid system to provide a flow of working fluid proximate to the heat-absorbing solid body, and a movement device to move the heat-absorbing solid body such that one or more surfaces of the heat-absorbing solid body are periodically exposed to incident solar radiation. The incident solar radiation heats a portion of the heat-absorbing solid body which in turn heats the working fluid.

Abstract: A solar receiver and associated components, systems and methods for use with a concentrated solar power plant. The solar receiver including a heat-absorbing solid body, an optical arrangement configured to direct light on to the heat-absorbing solid body, and a heat exchanger cowl proximate the heat-absorbing solid body arranged to provide a flow of working fluid over the rotor. In use, the light from the optical arrangement heats the heat-absorbing solid body which in turn heats the working fluid proximate the heat-absorbing solid body. The heat-absorbing solid body is movable relative to the optical arrangement from a first position to a second position such that the heat-absorbing solid body does not overheat.
