A solar chimney includes a solar collector which heats air in the chimney, producing updrafts which can be harnessed to perform useful work. The solar collector may be located inside or outside the chimney. The device may include a reservoir for storing a heat transfer fluid, thus enabling the device to be used during both day and night. The solar chimney may be equipped with both internal and external solar collectors, operating in parallel. The solar chimney may also be equipped with multiple external solar collectors, connected in parallel to a reservoir. The solar chimney of the invention provides a convenient and practical way to convert solar energy into electrical power.

1. Apparatus for collection and use of solar energy, comprising: a) a solar collector, the solar collector including: i) a generally cylindrical outer casing having a first aperture for allowing solar radiation to enter the outer casing,ii) a generally cylindrical inner casing, disposed within the outer casing, the inner casing having a second aperture for allowing solar radiation, having passed through the first aperture, to enter the inner casing,iii) a generally cylindrical intermediate casing, disposed between the inner casing and the outer casing,iv) a target substrate, located within the inner casing, for absorbing solar radiation in the inner casing,b) a generally cylindrical chimney, spaced apart from the solar collector, the chimney providing a path for flow of air by convection so as to perform useful work,c) a closed-loop conduit containing a heat transfer fluid, the conduit extending inside the chimney so as to comprise a heat exchanger for transferring heat of the fluid to air inside the chimney, the conduit being in fluid communication with heat transfer coils located inside the solar collector, the heat transfer coils being positioned to receive heat from the intermediate casing and the inner casing, wherein heat transfer fluid circulates from the coils disposed in the solar collector to the chimney and back to the coils disposed in the collector, andd) a solar reflector, the solar reflector being located outside of the solar collector and outside of the chimney and outside any other component of the apparatus, the solar reflector having at least one dimension which is greater than any dimension of the first aperture, the solar reflector comprising means for concentrating solar energy into a high-intensity beam at a focal point located in a vicinity of one of said first or second apertures, and for directing said high-intensity beam into the solar collector,wherein the inner casing has a heat absorptive inner surface, wherein the intermediate casing has a heat absorptive inner surface, and wherein the outer casing has a reflective inner surface,and wherein the outer casing is sealed and evacuated. 2. The apparatus of claim 1, wherein said second aperture includes a lens for concentrating solar radiation onto the target substrate. 3. The apparatus of claim 1, wherein the outer casing is insulated.
