Dynamic Window Breakthrough

Researchers at North Carolina State University in the US have developed a new dynamic window material that can tune out certain wavelengths of light and block heat to suit the conditions. 

Three Modes Now Possible 

The Dynamic window glass can be used to switch windows between three modes: transparent, or “normal” windows, windows that block infrared light (helping to keep a building cool), and tinted windows that control glare while maintaining the view. This three-mode option is a step forward from existing dynamic windows based on electrochromism (using an electric stimulus to change opacity) which can only switch between clear or dark modes.
