A SYSTEM FOR MAINTAINING A PREDETERMINED TEMPERATURE AT A GIVEN LOCUS, COMPRISING A REACTION VESSEL AT SAID LOCUS, METAL IN SAID VESSEL OF THE TYPE THAT COMBINES EXOTHERMICALLY WITH HYDROGEN TO FORM A HYDRIDE, SAID METAL REMAINING IN SAID VESSEL THROUGHOUT OPERATION OF SAID SYSTEM, A SUPPLY O HYDROGEN, VALVE MEANS FOR ADMITTING A CONTROLLED FLOW OF HYDROGEN FROM SID SUPPLY INTO SAID VESSEL AT DESIRED TIMES AND FOR CHANGING SAID FLOW AT OTHER DESIRED TIMES AND FOR STOPPING SAID FLOW AT STILL OTHER DESIRED TIMES, THE ADMISSION OF SAID HYDROGEN INCREASING THE PRESSURE IN SAID REACTION VESSEL AND THEREBY RAISING THE TEMPERATURE OF SAID METAL DUE TO THE EXOTHERMIC COMBINATION OF SAID METAL WITH SAID HYDROGEN, PUMPING MEANS FOR EXTRACTING HYDROGEN FROM SAID VESSEL, THEREBY LOWERING THE PRESSURE AND TEMPERATURE OF SAID REACTION VESSEL, TEMPERATURE SENSING MEANS AT SAID LOCUS, AND CONTROL MEANS ACTUATED BY SAID SENSING MEANS FOR ACTUATING EACH OF SAID VALVE MEANS AND SAID PUMPING MEANS ACCORDING TO WHETHER THE TEMPERATURE AT SAID SENSING MEANS IS HIGHER OR LOWER THAN SAID PREDETERMINED TEMPERATURE.
