Patent ID: 7821151

Claim:
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 plurality of windows to allow solar energy to heat air within the solar chimney, a first air turbine driven by said heated air rising in said chimney wherein said first air turbine drives a first generator to create electrical power to drive a load, 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 coils containing compressed air looped around an upper portion of said solar chimney, a plurality of heliostats focusing solar energy on said coils 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 and energy from said first turbine in response to said energy load and in response to the amount of solar energy available to said second turbine wherein said first turbine includes a power shaft driving said first generator and a clutch and transmission selectively control an amount of power from said shaft driving said compressor.
