A heat engine (H) has a heat input means (10) and a work output means (20). A property of a first working substance is cyclically changed in a first subsystem forming a property modulator (1). The property modulator is provided with a work transfer input means (3) and a work transfer output means (4), a heat input means (10), a heat transfer input means (5) and a heat transfer output means (6), the sum of said work transfer input and said work transfer output being equal to zero over a cycle of the heat engine. The property modulator (1) is connected to a second subsystem forming an energy converter (2) wherein said change in the property of the first working substance of the property modulator induces a corresponding change in a property of a second working substance of said energy converter. The energy converter (2) is provided with a heat transfer input means (7) receiving a heat input which is equal in magnitude but opposite in sense to the heat output of said heat transfer output means (6) of the property modulator (1), a heat transfer output means (8) delivering a heat output which is equal in magnitude but opposite in sense to the heat input of the heat transfer input means (5) to the property modulator (1) and means for converting said change in property of said second working substance of the energy converter (2) to work delivered to said work output means (20).
