In terms of micro turbines, a good fit for the Rossi reactor would be the supercritical carbon dioxide (S-CO2) Brayton-cycle micro turbines. The supercritical CO2 Brayton cycle provides the same efficiency as helium Brayton systems but at a considerably lower temperature (250-300 C). The S-CO2 equipment is also more compact than that of the helium cycle, which in turn is more compact than the conventional steam cycle. The size of such a micro turbine operating at 65% efficiency might be comparable to that that of an auto water pump matching the power production of a Rossi reactor in the megawatt range.
