NOVELTY - The compressor-less micro gas turbine (10) has a combustion chamber (4) which is in fluid communication with a compressed gas container for receiving gas from the gas container and heating the gas within the combustion chamber to create an expanded gas. A heater is adapted for heating the combustion chamber. A turbine (5) is in fluid communication with the combustion chamber for receiving the expanded gas. The heated gas drives the turbine. A generator (6) is coupled to the turbine. The turbine provides mechanical input to the generator and causes the generator to produce electricity.    USE - Compressor-less micro gas turbine for fuel cells, thermoelectric devices, combustion engines, and gas turbines.    ADVANTAGE - Prevents contamination of the turbine and protects the environment from the turbine since the casing is an active protective barrier between the turbine core and the ambient environment. Increases power and efficiency by varying the flow rate from the canister or the gas mixture using a valve or other flow control mechanisms. Enables simple replacement when the containers are expended since the working medium container and fuel container is easily accessible. Exhibits excellent portability due to the lightweight, high strength materials that makes up the compressor-less micro gas turbine. Exhibits high resistance to the effects of high temperature of the mechanical properties of the material since turbine is formed of polymer ceramic materials which provide low thermal conductivity and resistance degradation at operating temperatures required of optimal operation. Improves efficiency since the turbine provides mechanical input to the generator and causes the generator to produce electricity.
