Abstract :
Two designs that were developed as part of the advanced Stirling conversion system (ASCS) project managed by NASA Lewis Research Center are described. Each design features a free-piston Stirling engine, a liquid metal heat pipe receiver, and a means to provide about 25 kW of electric power to a utility grid while meeting the US Department of Energy´s long term performance and cost goals. An independent assessment showed that both designs are manufacturable
