<p>A solar energy collection and conversion system in which a cassegrain minor system (31, 33) is rotated about a diurnal axis, which axis is adjusted for seasonal variations in the incidence of the sun"s rays on the earth"s surface. Along the diurnal axis used for rotation of the collection system an elongate cavity (11, 13) filled with translucent or transparent fluid material is used for direct absorption of the sun"s rays. This is accomplished by providing the wall of this cavity (11, 13) with highly reflective surfaces so that substantially all of the incident solar energy is absorbed directly by the fluid medium and only an insignificant portion is absorbed by the cavity walls (11, 13). The fluid within the cavity may be maintained under extremely high pressures and temperatures in order to utilize this fluid as a heat storage medium. Such heat storage is facilitated by apparatus (175, 179, 187, 197) which permits a change in the volume of the reflective cavity (11, 13) in response to the temperature or pressure of the fluid within the cavity. </p> |
