DESIGN OF A 1.5 KW PORTABLE, ELECTRIC GENERATOR

THE EXPERIENCE GAINED FROM THE DESIGN AND OPERATION OF TWO PREVIOUS PROTOTYPES WILL BE USED AS THE BASIS FOR THE SYSTEM DESIGN AND PERFORMANCE EVALUATION OF A THIRD GENERATION FREE-PISTON STIRLING LINEAR ALTERNATOR SYSTEM CAPABLE OF RELIABLY PRODUCING 1.5 KW OF 60 HZ 120 VAC SINGLE PHASE POWER OR 1.4 KW OF DC POWER AT 12 OR 28 VOLTS. THE MACHINE WILL BE ABLE TO USE ANY AVAILABLE LIQUID FUEL, WILL BE HERMETICALLY SEALED, AIR COOLED AND RUGGED. ITS EXPECTED CHARACTERISTICS ARE: WEIGH ( EMPTY) 35 KG SIZE 70X30X45 CM (FIELD PACKAGE), FUEL LOAD 10 LITERS FOR BETTER THAN 12 HOURS OPERATION. COST IN COMMERCIAL PRODUCTION IS APPROXIMATELY $800. IT WILL REQUIRE ONLY ROUTINE MAINTENANCE OF THE BURNER (CLEANING) AND WILL BE STARTED BY CLOSING AN IGNITION SWITCH OR DEPRESSING A STARTER BUTTON. POWER CONDITIONING WILL BE AUTOMATIC WITH ANY LOAD FROM ZERO TO 1.5 KW. OVERLOADS OR SHORT CIRCUITED LOAD WILL DESTORY THE SYSTEM.
