Table IV- APP-2, (Cont'd) Pointing (to sun) requirement less stringent. DC output compatible with DC-RF converters Much experience with silicon solar cell space power systems; history of continued improvements. High voltage DC power transmission imposes design complexities to minimize weight. Ground test difficult (large, light weight structures). Maximum Theoretical efficiency - 22% for silicon cells. Potential long life, low maintenance with gas bearings; no wear out mode identified. Non- corrosive working fluid. Coupling of ground-based and aerospace turbomachinery technology required but net demonstrated High temperature (1800-2000*F) materials required for high efficiency (38-40%) conversion systems - technology developmen
