  • Patent number: 8347628
    Abstract: This invention relates to a Compressed Air Turbine-Generator, or CAT-G that will enable the ability to manage energy gathered from ecologically friendly sources, such as solar and wind power. Compressed Air Energy Storage, (C.A.E.S.), is a promising mode of clean energy storage. A major challenge facing this technology is the need to efficiently convert the compressed air energy into electricity. Conventionally, high-pressure air is used only to improve the efficiency of a conventional jet powered turbine generator. The focus herein is on a new technology that efficiently converts the energy stored in compressed air directly into electrical power without producing greenhouse byproduct gases or other pollutants. This new capability will add important flexibility to the optimization of ecologically friendly energy systems.

  • Patent number: 8041545
    Abstract: Concurrent Gradients Analysis (CGA), and two multi-objective optimization methods based on CGA are provided: Concurrent Gradients Method (CGM), and Pareto Navigator Method (PNM). Dimensionally Independent Response Surface Method (DIRSM) for improving computational efficiency of optimization algorithms is also disclosed. CGM and PNM are based on CGA's ability to analyze gradients and determine the Area of Simultaneous Criteria Improvement (ASCI). CGM starts from a given initial point, and approaches the Pareto frontier sequentially stepping into the ASCI area until a Pareto optimal point is obtained. PNM starts from a Pareto-optimal point, and steps along the Pareto surface in the direction that allows improving a subset of objective functions with higher priority. DIRSM creates local approximations based on automatically recognizing the most significant design variables.
