  • Patent number: 7821151
    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.
    Type: Grant

  • Patent number: 5190453
    Abstract: A staged combustor including a first combustion stage for combusting a fuel rich mixture of a fuel and an oxidizer. A plurality of serially positioned secondary combustion stages, downstream the first stage, are provided for receiving secondary flows of oxidizer to the increasing mass of combustion efflux. The gradual increase of oxidizer/fuel ratios provide a resultant substantially stoichiometric combustion. A cooling system is provided for cooling these combustion stages.
