Claims

1. IN A SEA WATER BATTERY MADE FROM A PLURALITY OF MAGNESIUM SILVER CHLORIDE COUPLES CONNECTED IN SERIES, EACH OF SAID COUPLES BEING MADE OF SHEETS OF SAID MATERIALS SPACED A SHORT DISTANCE APART TO DEFINE A GAP, SAID BATTERY BEING MOUNTED IN A BATTERY COMPARTMENT, AND SAID COMPARTMENT HAVING AN INLET PASSAGE AND AN OUTLET PASSAGE IN COMMUNICATION WITH THE TOP AND BOTTOM OF THE GAP OF EACH COUPLE TO PERMIT THE CIRCULATION OF ELECTROLYTE THROUGH SAID GAPS, THE IMPROVEMENTS COMPRISING A PUMP FOR PUMPING SEA WATER ELECTROLYTE THAT HAS PASSED THROUG THE BATTERY BACK TO THE INLET PASSAGE, AN ADJUSTBALE FLOW CONTROL VALVE FOR CONTROLLING THE AMOUNT OF ELECTROLYTE IN THE OUTLET PASSAGE THAT RETURNS TO THE SEA, AND CONTROL MEANS FOR SAID VALVE, SAID CONTROL MEANS RESPONSIVE TO THE MAGNITUDE OF THE OUTPUT VOLTAGE OF THE BATTERY FOR CAUSING SAID VALVE TO VARY THE RATE AT WHICH ELECTROLYTE FLOWS BACK TO SEA AS A FUNCTION OF THE MAGNITUDE OF THE OUTPUT VOLTAGE OF THE BATTERY, WHEREBY THE OUTPUT VOLTAGE OF THE BATTERY IS MAINTAINED WITHIN A PREDETERMINED RANGE OF VALUES.
