    • A central solar receiver comprising a tubular housing with a central axis, a radiation admitting aperture and an absorber chamber having an outer wall, two oppositely located ends, an inner-wall-forming substantially tubular transparent window co-axial with the tubular housing. The solar receiver further comprises injection means near a first of the oppositely located ends and at least one egress opening means near a second of the oppositely located ends. The injection means are capable of injecting into the absorber chamber a multicomponent fluid mixture comprising at least one radiation absorbing component and are so designed that the fluid mixture is injected into the absorber chamber adjacent and essentially tangentially to the outer wall, whereby contact between the mixture and the window is reduced. The egress opening enables the egress of the fluid mixture from the absorber chamber.

    • A solar thermal collector incorporates an extended reflector surface constructed to concentrate radiation from a radiation source along a focal line. The reflector surface is oriented in a generally upward facing direction relative to the earth with the focal line above the reflector surface. A tracking system supports the extended reflector surface for double axis tracking of the sun by relative motion of the reflector surface to different tracking positions for optimizing concentrated radiation at the focal line. The tracking system is constructed to maintain the focal line of the extended reflector surface in a substantially horizontal orientation relative to the earth during tracking. An elongate absorber is positioned substantially at the focal line for absorbing and converting radiation to heat energy. An elongate absorber housing is coupled to the extended reflector surface and is constructed for positioning the elongate absorber substantially along the focal line. The housing provides an insulating enclosure for the elongate absorber for reducing conduction heat loss. The housing is formed with an elongate aperture oriented in a generally downward direction relative to the earth for receiving and passing concentrated radiation from the extended reflector surface to the absorber. A leveling system is coupled to the absorber housing. The leveling system is constructed to maintain the absorber housing in a substantially horizontal attitude with the aperture facing downward relative to the earth during tracking to suppress convection heat loss from the absorber and absorber housing.

    • The present invention provides a method of and apparatus for producing power from solar energy wherein a solar collector heats gas supplied to a gas turbine; compressors compress the gas, the gas being compressed and stored gas during a first period of time, with the stored compressed gas being supplied to the gas turbine during a second period of time to produce power by driving an electric generator. Preferably, the first period of time is during periods of off-peak electricity, which normally occur at night. The second period of time is during the day. The solar collector preferably comprises tracking reflectors for focusing solar radiation and a receiver for receiving the focused solar radiation and also heating the gas. The solar radiation receiver preferably comprises a rotating ceramic member. Furthermore, a combustion chamber is preferably provided to heat the gas entering the gas turbine and is operated by a temperature sensing/control unit when the solar radiation received by the receiver is insufficient to heat the gas entering the gas turbine to the required temperature. The electric motor used to operate the compressors preferably comprises the electric generator of the gas turbine. Furthermore, heat generated during the compression of the gas and contained therein is transferred to another fluid in a heat exchanger which comprises part of waste heat converter for producing electrical power therefrom.
