primarily because of a highly reflective, precisely shaped mirror that focused almost all the reflected light onto the absorber. McDonnell Douglas, Suntec Systems, and Solar Kinetics designs were down about 10% in efficiency at temperatures near 3000C. The General Atomic FMSC performed at a lower level at low temperatures because of large reflected light spillover, but only about 3 to 4% lower than the others near operating temperatures of 300oC. Even the best of these collectors can be significantly improved. Show Less
