A CHEMOELECTRIC HEAT SOURCE FOR CONVERSION OF CHEMICAL ENERGY TO HEAT BY ELECTROCHEMICAL COMBUSTION WITHIN THE DEVICE TO BE HEATED, COMPRISING: (A) A BIMETAL CONTAINER HAVING NO EXTERNAL ELECTRICAL TERMINALS AND REQUIRING NO EXTERNAL ELECTRICAL CIRCUITRY BEING CONSTRUCTED OF TWO DIFFERENT METALS, PORTIONS OF EACH METAL BEING IN ABUTMENT AND IN DIRECT ELECTRICAL CONTACT WITH EACH OTHER AND A SUBSTANTIAL PORTION OF EACH METAL BEING EXPOSED TO FORM A PORTION OF THE INNER SURFACE OF THE CONTAINER, THE TWO DIFFERENT METALS WHICH FORM SAID CONTAINER BEING SUITABLE AS AND FORMING ELECTROCHEMICAL CELL ELECTRODES; (B) A SUITABLE ELECTROLYTE ADDED TO SAID CONTAINER FOR ACTIVATION THEREOF THUS FORM A SELF-CONTAINED HEATING UNIT, THE ELECTROCHEMICAL REACTION CREATED WITHIN THE UNIT BY ACTION OF THE ELECTROLYTE CAUSING AN IONIC CURRENT TO FLOW THROUGH THE ELECTROLYTE FROM ONE ELECTRODE METAL TO THE OTHER ELECTRODE METAL AND COMPLETE THE ELECTRIC CIRCUIT THROUGH SAID TWO DIFFERENT METALS IN CONTACT WITH EACH OTHER, HEAT BEING GENERATED BY CONVERSION OF CHEMICALS ENERGY TO HEAT AT A HIGH RATE ENTIRELY WITHIN SAID UNIT BY PASSAGE OF THE CURRENT THROUGH THE VARIOUS RESISTANCES OF SAID ELECTROLYTE AND TWO DIFFERENT CONTAINER METALS.
