SmarterShade uses optical filters to revolutionize window shades - CES 2014

The video discusses smart glass, a type of glass that changes opacity with electric current. The current technology is expensive, prompting research into optics and polarization. The result is a new film-based smart glass that doesn't require electric current, making it more affordable and easier to implement. This innovation has significant potential for energy efficiency in buildings by controlling solar heat gain and improving insulation.
