A sodium-chlorine generator generates electricity. Chlorine gas is combined with sodium metal in a boiler. The reaction is exothermic and generates sodium chloride as a biproduct. The heat can be used to boil water to generate steam. The steam generated can be used to turn a turbine, which produces electricity. The reactor can use a heat exchanger to connect a boiler that is separated from reactor. The rate and output of the reaction can be changed by pressurizing the chlorine gas with the reactor and by preheating the sodium before the reaction. The sodium chloride can be recycled to generate sodium metal and chlorine gas for a subsequent use.
