Abstract: A method and apparatus for receiving solar energy reflected from a heliostat configuration in which the apparatus is formed of converging vanes defining cavities therebetween, and preferably converging towards a cavity. The vanes may partially or completely define an enclosed volume. Surfaces of the vanes are provided with reflective surfaces near the outer portions of the receiver, selective surfaces at the intermediate portions and, optionally, absorbing surfaces at the interior portions. Cooling means are provided within the vanes of the receiver adjacent the selective and absorbing surfaces. In a preferred embodiment, a transparent barrier is provided transverse to the vanes substantially at the change from the reflective to the selective surfaces, and an infrared absorbing heat transfer fluid is flowed inwardly from the transparent barrier to the cavity to cool the receiver and absorb energy irradiated from the vanes and cavity.
