Calculations of the thermodynamic and electrical properties of dry combustion plasma (DCP) produced by seeded combustion of a typical charcoal CSC, show that its adiabatic flame temperature and electrical conductivity are remarkably higher than those of conventional plasmas from fossil fuels hitherto employed in experimental MHD generators. Both these properties are strongly dependent on the concentration of HxOy species in the plasma. The results have been compared with data on the conventional plasmas.
