Abstract: A compressor-less micro gas turbine has a compressed working medium container for maintaining a gas turbine under pressure. A combustion chamber is in fluid communication with the compressed gas container for receiving a gas from the gas container and heating the gas within the combustion chamber to create an expanded gas. A heater heats the combustion chamber to expand the working gas therein. A turbine in fluid communication with the combustion chamber for receiving the expanded gas. The expanded gas drives the turbine. A generator is operatively coupled to the turbine. The turbine provides a mechanical input to the generator causing the generator to produce electricity.
