High Temperature Superconductor (HTS) cryocooling is costly and maintenance prone. Recent investments have developed HTS technology and markets, but little progress has been made in the critical enabling cryocooler technology. Infinia Corporation?s innovative Multi-Cylinder Cryocooler (MCC) addresses commercial needs in a cost-effective manner and to a significantly higher degree than any existing alternative due to a unique integration of Infinia?s proven long-life, high-reliability, maintenance-free flexure bearing and clearance seal technology with a patented high capacity, double-acting free-piston Stirling cycle configuration. During Phase III, Infinia proposes to address commercial needs in a very cost-effective manner. Phase III would produce refined second and third generation MCC units that would culminate in a real world field demonstration at an HTS installation such as a transmission line.
