Thermal solar systems have been around for years, a proven technology.
For mass deployment you need to focus on the manufacturing, installation and maintenance issues: total-cost-of-ownership drives the cost per KWh.
Sandia Corporation and others unveiled their second generation thermal solar collectors recently. The focus on mass deployment is visible.
The new SunCatcher is about 5,000 pounds lighter than the original, is round instead of rectangular to allow for more efficient use of steel, has improved optics, and consists of 60 percent fewer engine parts. The revised design also has fewer mirrors — 40 instead of 80. The reflective mirrors are formed into a parabolic shape using stamped sheet metal similar to the hood of a car. The mirrors are made by using automobile manufacturing techniques. The improvements will result in high-volume production, cost reductions, and easier maintenance.
If nothing else, the view is stunning.
