[文摘]:The development of a 1O-watt free-piston Stirling/linear alternator generator continues through fabrication and testing of a laboratory demonstration model. This model is the first generation of hardware for a program that will ultimately yield a long life maintenance-free 10 watt generator set. System efficiencies greater than 17 percent have been demonstrated and efficiencies greater than 20 percent are expected for subsequent generations of hardware with improved thermal insulation. The system has operated with a heat rejection temperature between 303 and 363 K, at a nominal heater temperature of 873 K. (Author)
