Schapiro (2011) introduced the BARM as an internal combustion machine, and Schapiro (2012) introduced the BARM as an external combustion machine. This article introduces the thermodynamics of an external combustion BARM in the physical approximation (Chap. 3), designed specifically for exploiting thermosolar energy. The economic and political aspects are discussed in Clause 4.3. A comparison between BARM and Stirling machines is the primary focus of this article. The efficiency of both machines as thermosolar energy exploiters is compared under two scenarios: in the first, the Stirling machine has no heat recuperator and the BARM no heat exchanger. In the second scenario, the Stirling machine is equipped with a heat recuperator and the BARM machine with a heat exchanger. That efficiency is dependent on the power flow through the machine has been taken into consideration. The thermodynamic description, that is the modelling of these processes, is a physical approximation valid not only for BARMs, but for all rotational volume displacement machines in similar application, for instance, in Pyatov (2010) and Pyatov and Schapiro (2010).
