A device for converting heat into mechanical energy is disclosed. The device includes a channel flow boiler having at least one channel adapted to heat a working fluid for generating a liquid-gas mixture; an expansion device adapted to expand the liquid-gas mixture; and a movable element arranged such that the expanding liquid-gas mixture at least partially converts an internal and/or kinetic energy of the liquid-gas mixture into mechanical energy associated with the movable element; wherein the channel flow boiler and/or the expansion device is adapted to supply heat to the liquid-gas mixture.
