In collaboration with Sunpartner Technologies, Lyon, France-based Vision Systems will unveil a solar-powered, autonomous dimmable aircraft window dubbed Energia next month at the NBAA Convention in Las Vegas. Using Sunpartner’s Wysips (“What You See Is a Photovoltaic Surface”) technology, solar energy is harvested on the ground or in flight and stored in a battery integrated into the window. The generated electrical energy allows the dimmable system to run during the flight. The design eliminates the need for network cabling, making installation and maintenance easier.
