The invention relates to a heat engine for using environmental heat of uniform temperature, which is in a state of internal equilibrium such as, e.g., normal heat from air or water. Apart from directly driving vehicles, it is particularly suitable for relatively large stationary drives such as, e.g., for generating electrical energy in power stations. In order to be at all able to use heat of uniform temperature, i.e. without the presence of a natural thermal gradient with respect to a heat reservoir located outside the heat engine, according to the invention the heat engine is designed with a two-part gas circuit. In this case, the working medium of the one subcircuit is compressed via a two-stage compressor with intermediate cooling and fed to a binary nozzle, while the other part of the working medium (cold and uncompressed) is sucked in directly by the binary nozzle after previous absorption of heat from the environment and of the waste heat derived from the intermediate cooling. The mixed product which is obtained from the two components of working material from the two subcircuits in the binary nozzle and which has the new pressure (the mixed pressure) and the new temperature (the mixed temperature) is finally fed to an expansion machine (gas turbine), and fed again expanded and cooled to the environment (in the case of open operating mode) or to the heat exchanger (in the case of closed operating mode) for the purpose of renewed absorption of heat. Since before this the working gas ... Original abstract incomplete.
