Hybrid solar thermal chimney

A solar power arrangement for converting solar energy into electricity comprising;

• a solar chimney said chimney having a flared base spaced from the ground, said chimney including a transparent surface to allow solar energy to heat air within the solar chimney, a first air turbine wherein said first air turbine drives a first generator, said chimney including an exhaust;
• wherein said first air turbine drives an air compressor and wherein said compressor includes an ambient air intake and a plurality of pipes for receiving compressed air looped around an upper portion of said solar chimney, a plurality of heliostats focusing solar energy on said pipes to heat the compressed air contained therein and a second turbine driven by expansion of said compressed air wherein said second turbine drives a second generator and wherein a controller controls the speed of said compressor in response to said energy load and in response to the amount of solar energy available.
