In a method for converting heat energy into mechanical energy, carbon dioxide, which is stored in a reservoir (11) is used as working medium in a cyclic process and heat energy is fed to the working medium during the cyclic process. The working medium is then isenthalpically expanded in an engine (15), a part of the heat energy absorbed is drawn off and converted into mechanical energy; one fraction of the working medium leaving the engine is then converted by sublimation into crystalline carbon dioxide and then melted and in turn fed to the reservoir. The other vaporous fraction of the working medium remaining is, on the other hand, compressed adiabatically and introduced as condensate into the reservoir (11). By means of this method it is possible without any great difficulties and without major design expense to utilise the limitless environmental heat available as mechanical energy. In so doing, no environmental damage occurs nor does any pollution have to be accepted. <IMAGE>
