Abstract: Miniaturized gas turbine generator made using automotive turbo charger, by using optimized combustion camber design. The fuel being used here to power the gas turbine is Bio-Diesel which is one of the eco friendly fuel available .The engine can run on any eco friendly fuels .Here the power is been extracted by using impulse turbine at the exhaust of the engine. The combustion camber is optimized in such a way that the efficiency is more than 90%.
