Abstract
A solar power arrangement for converting solar energy into electricity comprising; a solar chimney, the chimney having a flared base spaced from the ground the chimney including a transparent surface to allow solar energy to heat air within the solar chimney. A first air turbine drives a first generator, and the chimney including an exhaust. The first air turbine drives an air compressor and wherein the compressor includes an ambient air intake and a plurality of pipes for receiving compressed attached to the solar chimney. A plurality of heliostats focus solar energy on the pipes to heat the compressed air contained therein and a second turbine driven by expansion of the compressed air wherein the second turbine drives a second generator.
