<p class=MsoNormal>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<o:p></o:p></p>
