Florida-based SAF-GLAS, which creates disaster-resistant and security-related glass products, recently introduced EnergyGlass at a solar seminar at GlassBuild America. This transparent glass incorporates inorganic nanoparticles into clear laminated glass. With its use of a proprietary polycarbonate interlayer and patented film, this turns a window into a 24-hour a day solar “farm.” (Photo by Ecstaticist, Flickr)
