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.
