Abstract The statistical thermodynamics of far from equilibrium systems has undergone an amazing development within the last years. These recent results reached far beyond linear response theory and replaced the usual thermodynamic inequalities between work and free energy by equalities. Nevertheless, these new relations were recently extended to the context of thermodynamic processes with feedback, where the manipulation of a mechanical parameter is based on the information obtained from measurements of the same parameter. One of the most striking results of this thermodynamics of feedback is that the information accumulated by the observer determines the upper bound for the work extracted in cyclic process. In this proposal, we intend to develop a model such that the observer is included in the system and extend the above mentioned results to this situation. We want to verify, for example, whether such model would transfer energy from a cold to a hot reservoir at the expense of recording information but without absorbing any amount of external work.
