Underwater propulsion system

Claim 1

IN COMBINATION, A CLOSED CYCLE HEAT ENGINE CONTAINING A WORKING FLUID, A COMBUSTION SYSTEM HEAT SOURCE, AND HEAT TRANSFER MEANS OPERABLE TO CONDUCT HEAT ENERGY FROM SAID COMBUSTION SYSTEM TO SAID WORKING FLUID, SAID COMBUSTION SYSTEM BEING CAPABLE OF HEATING SAID WORKING FLUID TO A TEMPERATURE ABOVE ABOUT 1000*F. SUITABLE FOR THE EFFICIENT OPERATION OF SAID ENGINE; SAID COMBUSTION SYSTEM BEING COMPRISED OF A MOLTEN ALKALI METAL FUEL TAKEN FROM THE GROUP CONSISTING OF LITHIUM AND SODIUM; AN OXIDIZER CONTAINING REACTIVE FLUORINE ATOMS IN THE MOLECULE, SAID OXIDIZER BEING COMPRISED OF ONE OR MORE OF THE MATERIAL TAKEN FROM THE GROUP CONSISTING OF CXCLYFZ, WHEREIN X, Y, AND Z ARE INTEGERS, X HAVING A VALUE IN THE RANGE OF FROM 1 THROUGH 10, Y HAVING A VALUE OF ZERO OR GREATER, Z BEING ALWAYS EQUAL TO OR GREATER IN VALUE THAN Y BUT NEVER ZERO AND THE VALUE OF Y PLUS Z BEING CONSISTED WITH THE VALVE OF X IN ALKANE AND CYCLOALKANE TYPE ORGANIC COMPOUNDS; AND MEANS TO ADD SAID OXIDIZER TO SAID FUEL IN THE GASEOUS STATE IN A CONTROLLED QUANTITY WHEREBY THE HEAT GENERATING COMBUSTION REACTION MAY OCCUR, THE REACTION PRODUCTS OF SAID COMBUSTION SYSTEM BEING NONGASEOUS AND SUCH THAT SAID COMBUSTION SYSTEM OPERATES AT NEARLY CONSTANT VOLUME.
