SOLYNDRA --what type of glass is SOLYNDRA made of ? It is illegal to use annealed glass on roofs -facades- skylights- awnings etc. -ONLY TEMPERED SAFETY GLASS THAT BREAKS SAFETLY INTO MINI PIECES CAN BE USED IN CONSTRUCTION ON ROOFS. There is nothing special about solar collectors that exempts the solar industry from safety laws regarding the use of glass in construction . The IAMPO 2006 SOLAR CODE SAYS THAT ONLY TEMPERED GLASS CAN BE USED IN SOLAR COLLECTORS. Annealed glass breaks into dangerous razor sharp dagger like spears when it breaks. SOLYNDRA statement that a curved surface collects more energy than a flat surface is absurd. Please have someone at SOLYNDRA take a course in geometry and learn what the ANGLE OF INCIDENCE TO THE GLASS MEANS. I T IS IMPOSSIBLE FOR A CURVED SURFACE THAT COVERS THE SAME AREA TO COLLECT AS MUCH ENERGY AS A FLAT SURFACE. Even at solar noon at 0 angle of incidence to a flat surface ONLY THE 10 TO 2 O'CLOCK POSTION IS AT an EXCELLENT ANGLE OF INCIDENCE ! As the sun moves off due south or the collector surface moves off due south - evacuated tubes or any curved surface is at a disadvantage to a flat surface. Gator tom
