Synergy is a light refractive system inspired by the wings of the Blue Morpho butterfly. By redesigning the traffic light and switching from artificial to bioluminescent light with algae, Synergy reduces traditional energy usage and light pollution. The traffic light sequesters carbon above ground and converts it to oxygen. By using piezoelectric sensors on the rails of the subway to generate electricity and fiber optic cables to channel natural light from above ground into subway stations, Synergy creates a self-sustaining loop and a more sustainable urban transportation experience.
