  This extended abstract contains an outline of the work reported at the
conference IQIS2018. We show that it is possible to exploit a thermalization
process to extract work from a resource system $R$ to a bipartite system $S$.
To do this, we propose a simple protocol in a general setting in the presence
of a single bath at temperature $T$ and then examine it when $S$ is described
by the quantum Rabi model at $T=0$. We find the theoretical bounds of the
protocol in the general case and we show that when applied to the Rabi model it
gives rise to a satisfactory extraction of work and efficiency.
